Preface of

‘‘AMS special


Dear Readers,

This issue, which is dedicated to the upcoming BAUMA 2010 that will be held in April in Munich, will consist of a one-time special edition of our scientific journal „ADVANCED MINING SOLUTIONS“.

The BAUMA 2010 Trade Fair in Munich Presents Itself in a Sensational Dimension! Once again this time in April in Munich, the international trade fair for Construction Machinery, Building Material Machines, Construction Vehicles and Equipment presents itself as the world’s largest fair in terms of area. The record area of 555,000 square meters already reveals the dimensions of this fully booked event. In order to meet the booking demand, new temporary halls have been set up prior to BAUMA. Thus, the BAUMA of this year achieves dimensions, which have not been achieved before. Based on the current state of knowledge, over 30,000 exhibitors are expected to attend BAUMA 2010, with a record share of 50% international exhibitors. Compared to 2007, this constitutes a further enhancement of BAUMA’s international character.

Issue 01 | 2010

The scope of this huge event, as well as the support of the numerous exhibitors in times of the general economic crisis reveal that in most of the industrial and threshold countries, the construction sector has grown more that the entire economic activity, thanks to public economic stimulus packages. The great interest in this exhibition evokes hope that in most countries, rising growth rates for the construction sector can be expected for the year 2010, and even more for the year 2011. The BAUMA 2010 sets the stage for the time after the crisis. The long-term outlook for the building industry, for the construction materials industry, for mining and for engineering can be positively assessed globally, due to the rapidly growing markets of Asia and other regions, like for example Brazil. Although the high growth rates of the years 2003 to 2008 are a thing of the past, for the year 2011 onwards, growing markets in the construction industry are predicted for India and China in particular, and in a smaller scope for the US, Russia and Europe.



Since the year 1954, in which BAUMA was held for the first time, the exhibition has undergone a constant development and has evolved into a globally leading exhibition for the entire construction machine industry. Thanks to its ever new record numbers it has grown into the biggest trade fair of the world. The internationally announced BAUMA innovation award, which is being awarded at the beginning of the exhibition, shows that BAUMA has also developed into a market place of innovative technologies and innovations in this sector.

The subject of environment and sustainability is also part of the comprehensive spectrum of this year’s BAUMA 2010. One main focus of the near future is for example the reduction of emissions, due to the fact that new exhaust guidelines are coming into effect. Since the Guideline 97/68/EG and the US-exhaust law „Tier 4 interim“ have been tightened, new threshold values for emission of non-road vehicles like dredgers, road rollers and milling machines will

exhaust gas recirculation alone will not be sufficient any more. In order to meet the regulated reduction of emissions with new technological lines of sight it will be necessary to rethink and further develop in the area of exhaust after-treatment. It will be interesting to discover the answers that manufacturers have found. It is for the above-mentioned reasons that, prior to BAUMA, we have decided to use the new dimensions of BAUMA as an occasion to issue a special edition in which we are aiming to inform on selected innovations, new technologies and product novelties, which can be discovered and experienced on the exhibition from the 19th to the 25th April 2010. In this issue we will slightly deviate from the usual form of our magazine, in order to adjust ourselves to the innovative character of BAUMA. Instead of the section on “Further Training”, which is being continued in the next issue of AMS, we will report on the BAUMA innovation award. The nominations of this award are differentiated and assessed in the five categories of machinery, machinery component, construction process / construction work, research and design.

come into effect soon. The regulation of lower exhaust values challenges the construction machine sector into developing new, alternative technology solutions. As an example it is required to reduce threshold values for particles by 94 percent, compared to the current stage III A. Previous engine modifications like mechanical and electronic control, common-rail systems, charging and

In judging the nominated innovations, the jury of experts has paid particular attention to the following criteria: • Forward-looking development • Practical use • Contribution to environment and humanization of work • Improvement of efficiency and productivity while reducing energy and costs at the same time • Image value for the construction equipment, building material machinery industry or the construction and building material sector

This is followed by our “Transfer of Technology” section, in which we present some new technological developments, as well as first experiences in the application of new technologies. Subsequently, in our “News and Reports” section you will find a selection of current product novelties, which on the occasion of BAUMA are being presented to the expert public by manufactures for the first time. We thank you for your trust and hope that we manage to please you with this extraordinary special edition. Your AMS-ONLINE editorial team

There are three nominations in each category, and the award is being given to one of each at the onset of the exhibition. Within the framework of this special edition we will introduce to you a selection of the innovations that we believe are the most spectacular ones.

New product! New vertical drilling machine TERRA-DRILL for geothermal power With 35 years of experience in horizontal trenchless pipe and cable laying the Swiss manufacturer TERRA AG has joined the vertical drilling market with the development of its TERRA-DRILL. The design of this new vertical drill for geothermal power has taken 2 years. The aim of this intensive devolvement was to develop a compact geothermal drill that would be as powerful as conventional large drilling machines, but small enough to be employed in residential gardens for the heating of existing old buildings.

New Design Most often, large vertical drilling rigs cannot be used in gardens, as their massive weight and steel crawler tracks ruin the existing garden. If they are to be used, they are often lifted into the garden, which is difficult and expensive. This is why the TERRADRILL has a modular design. Drill rig and power pack are separated. In the transportation mode the TERRA-DRILL is only 0.95 m (37.4”) wide. It can drive through 1.00 m (3.3 ft) wide entrance doors. Its low weight of 2.1 tons (4’620 lbs) and it is rubber crawlers prevent damage to the garden and pathways.

Pic. 1: The new vertical rig TERRA-DRILL 4007 V for geothermal bores.

Machine technology The TERRA-DRILL 4407 V can drill vertical bores up to a depth of 120 m (400 ft) in most ground conditions. It has a torque of 4’400 Nm (3’300 ft.lbs) and a pull back force of 70 KN (7 tons). Casing pipes up to 178 mm (7”) OD can be drilled down to the upper rock edge. These casings protect the bore channel from collapsing. Smaller casing pipes with 133 mm (5.2”) OD and 152 mm (6”) OD can also be used. The 5“down-the-hole hammer is equipped with a drill bit of 150 mm (6”). It drills through most rock and mixed ground. This large 5 inch bore channel allows the geothermal sonde to be lowered the final drilling depths. The 5“ down-the-hole hammer is powered by an air compressor supplying 19 m3 /min @ 21 bar (630 cfm @ 3’000 psi) to reach optimum productivity. If smaller compressors are to be used, a 4” down-the-hole hammer is offered. The drill rods are 1.5 m (5 ft) long and have a diameter of 89 mm (3.5”).

Issue 01 | 2010


RESEARCH & INNOVATION The TERRA-DRILL is equipped with a small power pack allowing it to be self propelled. The separate main hydraulic power pack is driven by a 24 kW (33 HP) Diesel engine, which is “clean” and fulfils the world wide environmental emission requirements for the foreseeable future. The duplex piston pump in the power pack hydrates the compressed air to ensure a continuous discharge of the drilling mud.

The new patented duplex connector (mud spill preventer) The TERRA-DRILL operates with only one driving head. Thus TERRA has designed a new patented duplex connector (mud spill preventer) which allows simultaneous insertion of the casing pipe, the down-thehole hammer and the drill rods. The duplex connector conducts the drill mud cleanly into the mud containers ensuring that the job site is always clean. As soon as the casings have reached the upper rock edge, the bayonet connection of the duplex connector is released. From that moment on only the drill rods with the down-the-hole hammer proceeds to drill further down.

Triplex clamping and break-apart system The TERRA-DRILL is equipped with a triplex clamping and break-apart system. The assembly and disassembly of the casings and the drill rod is undertaken hydraulically.

Cable winch with handling device The electric cable winch and the specially developed rod handling device enables the lifting and loading of a single casing and a single drill rod simultaneously into the drill rig whereby they are assembled hydraulically. The handling device is also used for the disassembly of the heavy casing pipes.

Air drilling and fluid drilling In rocky ground it is recommended to use the air drill method with the down-the-hole hammer as it is faster. If the geology consists of loose ground, even at great depths, the TERRA-DRILL can be equipped with an optional drilling fluid pump to allow drilling using the “fluid method”. Here up to 600 ltr/min (160 gpm) of bentonite drilling fluid is pumped into the bore channel with a pressure of 4-6 bar

RESEARCH & INNOVATION Pic. 3: The newly designed and patented duplex connector (preventer) allows a simultaneous drilling of casings and drill rods. It conducts the drill mud cleanly into the mud containers without spillage..

(60-90 psi). This drilling fluid is pumped through the drill rods and tricone chisel at the drill face and forces the bentonite back to the top of the bore to stabilise the bore channel and remove the spoil. At the top the Bentonite is conducted via the duplex connector (mud spill preventer) into both mud containers.

Supported by the BFE The Swiss association “Gütesiegel Erdwärme“ (Association for Geothermal Drilling Companies) has published, that 1.400.000 meters (4.600.000 ft) of geothermal earth drilling had been completed in Switzerland in the year 2007 using large drilling rigs. At present there are approximately 300 large drilling rigs operating in Switzerland. The Swiss Federal Office for Energy (BFE) supports the design of the completely new geothermal drill rig TERRA-DRILL with the aim of utilizing geothermal power even in small residential properties.

Innovative drilling procedure for below-surface geothermal energy With the use of the electro-impulse procedure (EIV) decisive savings in drilling costs can be reached for below-surface geothermal energy. In the earth‘s crust (lithosphere) there are nearly inexhaustible reserves of thermal energy stored. In order to produce electricity from this, the hot dry rock technology is used. For this, at least two drillings are sunk into the hard bedrock. Hereby. one drilling serves as injection drilling, the other is an extraction drilling for the heat transfer medium. The rock functions as heat exchange.

Pic. 1: Destruction of rocks by electro-impulse procedure in different kinds of rock (Granite, Basalt, Limestone, Sandstone).

Above ground, the extracted heat is conducted to a steam cycle by which a turbine can be moved. This technology offers the opportunity of building a base load power plant independent of the wind and the sun. The required temperature level in the rock for an economical power plant stands at 130°C and is reached only at depths of 3000 m. Conventional drilling equipment is suitable for the sediment rock of oil - and gas deposits. In rock such as granite it drills only very slowly (1 – 2 m/h) and wears out quickly (a lifespan of 50 – 60 h). Changing the equipment due to the wearing out, so-called roundtrips, is very time-consuming as the entire drill string has to be dismantled and then reinstalled. At a drilling plant‘s daily cost of € 18,000, these standstill times run up enormous costs. Depending on the case, the total costs come to € 8 – 13 Mi for 5,000 m of drilling. The economic success of a below-surface geothermal energy project is connected to the availability of an economical drilling technology.

Issue 01 | 2010

EIV offers a technical alternative to the conventional drilling procedure. It uses the destructive effect of the high energy electrical charges which are produced inside the to be loosened material. The loosening process is, then, fundamentally changed. Instead of the ultimate compressive strength of the rock, its tensile adhesive strength must now be overcome. This means a reduction of the loosening resistance of 90% in the mean. The electrical voltage used consists of 300,000 V and discharges itself within 1/10,000,000 s. The pressure and the temperature in the resulting breakdown canal increases abruptly, which causes the rock structure to fail. Hereby,the electrodes between which the breakdown is produced are lying on the rock only loosely. In the framework of a project supported by the Federal Ministry of Environment, Nature Conservation and Nuclear


RESEARCH & INNOVATION Safety, a machine concept was developed by which this innovative loosening procedure can be integrated into the drilling technology. Thereby, a down-hole-tool was created that can be integrated into the drilling process like a conventional drilling tool. Changes to the drilling plant or additional equipment is not needed. Supplying the energy takes place via a flush-driven drilling engine which runs an electric generator. Its voltage at the start is reshaped over a rectifier and conducted to the surge voltage source (Marx principle) which generates the surge voltage for the output process. The output electrodes are arranged in such a way that the drilling hole floor level is reduced full-surface without the EIV drilling system having to rotate in the hole. The discharge of the drilling cuttings takes place in the conventional mode via flush – drilling. A flushing-medium that satisfies electric drilling and electrical requirements has already

been tested successfully. The technical challenge for the practical implementation of the EIV drilling system consists foremost of the adaptation of the electrical and electronical components to the high temperatures of up to 200°C in the drilling hole. Additionally, there are the high pressures of 100 bar and the small drilling hole diameter of 12 1/4“ (311 mm). Concepts on the basis of already existing technical solutions show that the realization of a prototype is possible despite these high requirements. The main advantage of the EIV drilling system is that wearing out does not occur due to the absence of mechanical forces to the mining equipment. A burn-off of the electrodes due to the charges is not to be expected. The lifespan is presently estimated at 500 h. The number of equipment changes due to wearing out is minimized. The aim is to completely avoid them. In addition, there is the to be expected drilling speed in the granite of 4m/h.

RESEARCH & INNOVATION Pic. 3: EIV – Drilling Tool for deep geothermal wells

The savings potential in respect to the drilling costs is calculated at 30% on the basis of the average return method with drilling data from practice. The result of this development shows that the utilization of the EIV technology makes it possible to lower the drilling costs and, hence, the energy accrual costs for below-surface geothermal energy to that of the water-and wind power level.

Die BAUER Maschinen GmbH nominated for the BAUMA Innovation Award 2010 A new development of Bauer Maschinen GmbH was nominated for the BAUMA Innovation Award 2010 in the category „Machinery Component“. What is simply called „Down-The-Hole flushing head for dry drilling rods“ represents a breakthrough: This Bauer innovation enables to significantly increase the performance of Kelly drilling rigs for drilling in rocks. Additionally, this innovation results in an ecological benefit: The „Down-The-Hole flushing head“ supersedes the cost-intensive set-up of a slurry drilling system with slurry tank and slurry treatment plant. This new method has been successfully used several times: In May 2009 in Finland, since then also in Russia – in Vladivostok, and for the building projects of the Olympic arena in Sotchi–, in Singapore and in Australia.

The Bauer Down-The-Hole flushing head The Kelly drilling system is the most efficient method for the production of bored piles as the intermittent soil extraction from the borehole is not energy efficient and the drilling tool can be selected for each soil layer without any loss of time. Furthermore, the required space for the equipment and the boreholes are reduced to a minimum.

Upon reaching the rock layer, the newly developed Down-The-Hole flushing head can be used together with the subjacent roller bit full section drilling head or a roller bit core barrel – as any other Kelly drilling tool – coupled to the Kelly bar. An air supply hose which is coiled outside the borehole is connected to the Down-The-Hole flushing head.

Upon drilling in very strong rock – as often required - passive drilling tools, also with the use of roller bits, can only achieve a very slow drilling progress as the loosened rock chippings are not instantly removed and therefore strongly interfere the further loosening process of the rock by the roller bit. Due to the telescoping of the Kelly bar and the permanent rotation of the drilling tool, the supply of flushing energy to the drilling tool was not possible until now. Longtime efforts to seal the Kelly bar and to turn it into a „flushing Kelly“ or to direct a simultaneously rotating hose downwards were never successful or suitable for jobsites. Previously, an improvement was only achieved by an extensive refurbishment of the drilling rig towards a flush drilling system with multiple drill pipe sections and the respective method for the slurry circulation (flushing head, slurry tank, etc.); there was a high demand of energy for the fluidic extraction of the rock chippings throughout the complete length of the borehole.

Pic. 1: Practical use of Down-the-hole-flushing head

Issue 01 | 2010


RESEARCH & INNOVATION If the drilling tool touches the drilling horizon and is pushed downwards by the feeding system of the drilling rig, the stator of the Down-The-Hole flushing head is seized with the lever system at the borehole wall. This avoids the connector of the air supply hose to simultaneously rotate with the rotor, which transfers the rotation of the Kelly bar to the drilling tool. The air flushing is conducted to the rotor via the pneumatic multiport swivel and drives the flushing by risers in the drilling tool using the air-lift method. The rock chippings are permanently transported to a tank in the upper part of the drilling tool. The transport of the loosened material to the surface is intermittently carried out in the same way as upon Kelly drilling by retracting the Kelly bar and emptying the tank outside the borehole.

Pic. 2: Schematic illustration of Down-the-hole flushing head

With the same method, besides air also water, hydraulic oil or electric current can be lead downwards, which for example also enables the driving of a Down-The-Hole hammer.

Norton-Clipper - Foam Drilling System The patent-pending Foam Drilling System from Norton-Clipper is an innovative solution for diamond drilling in reinforced concrete. It replaces water as a coolant with foam.

The Foam Drilling System Using foam as a coolant allows a much easier collection of the coolant and slurries which means ability to work on job-site that need to remain very clean and exempt of water contamination; this can be for instance drilling holes for pipes in a inhabited house, where it is very difficult to perfectly protect the surrounding; this can also be very regarding job sites like nuclear plants where water contamination is forbidden. An obvious benefit is time saving : instead of spending hours to protect the surroundings against water spraying, or to clean the job site after drilling, the contractor can install his equipment very quickly and leave the job-site without spending time to clean it. This brings great benefits for instance on small renovation job sites. Another benefit is saving of water : to generate the foam, water is mixed with a environment friendly foaming agent, however while drilling, the consumption of water is reduced by 2/3 thanks to the effect of the foam!

Pic. 1:

Practical use of the Foam Drilling System

Pic. 2: Recording from the practice

This system can be used jointly with all standard wet drilling rigs and motors existing on the market, so the contractor does not have to invest in additional equipments. However it cannot be used with standard diamond corebits : it requires special type of corebits, adapted to foam drilling, and developed by Norton-Clipper. The Foam Drilling system is made of a compact and easy to move foam-drilling-unit (including a compressor and a tank, which is transforming water into a foam having the right consistency), a transformer tank and a vacuum. Foam drilling will soon become the preferred solution for professional drilling contractors.

Glass beads instead of gravel or sand as a supporting material in bore wells An innovation from Ochs that guarantees that water catchment wells have a longer, better and more economic service life.

Glass beads as a supporting material in bore wells Pure and clean water is the most important raw material for human life. Bore wells are required to extract ground water. These wells consist of three essential components. • The bore hole, the depth and diameter of which are determined by the position and thickness of the waterbearing soil layers to be opened up. • The well filter pipe to be fitted inside the bore hole, through whose slots water can flow from the well pipe.

Gravel or sand has been used as supporting material until now. In Germany, these are recorded in DIN 4924 for well construction that describes the minimum required material properties. Naturally occurring gravels and sands impose limits on the requirements in terms of roundness, dimensional accuracy, surface quality and, in particular, the strength of the individual particles needed by modern well construction. The innovations from OCHS GmbH consist in using glass beads as a supporting material between the bore hole wall and the well filter pipe. This pipe has the following decisive benefits for well construction:

• The supporting material in the annular space between the fixed bore hole wall and the well filter pipe.

The selection of this material is of crucial importance when constructing wells. Its purpose is to support the layers of soil particles at the wall of the bore hole in such a way that clear and sand-free water is able to pass through the free pore spaces to the well filter pipe with as little resistance as possible. Selecting the right particle size and material is of crucial importance for the strength and problem-free operation of the well over many years. If the material is too fine, an unwanted filter effect will be created and block the pore spaces with the consequence that the well will run dry. If the supporting material selected is too coarse, the well will permanently transport sand particles and cloudy material with the water from the bedrock. Pic. 1: Comparison of conventional gravel and glass beads

Issue 01 | 2010



Pic. 2: By undersized particle blocked filter-slots

• Between four and ten times greater strength than comparable sand and gravel material • Optimal roundness for virtually the same particle size. This results in a greatest possible free pore space, regardless of the size, through which water can flow unimpeded. • A surface that is virtually perfectly smooth • Optimal size adjustment to the water-bearing soil layers is possible, as the glass beads can be produced between 0.4 mm and 16 mm diameter at 0.1 mm intervals. • Hygienically safe material combined with high chemical resistance, e.g. to disinfectants

The smooth surface, in particular, with the virtually perfect roundness of the glass beads guarantees that the water catchment wells can be operated more economically. Water can flow through the glass beads unimpeded with as little resistance as possible. This can result in high potential savings in the electrical energy required to transport water from a great depth, as the overall fall in the water table in operating the well is reduced. As glass beads can be supplied without undersized and undersized particles, these can be optimally adjusted and fitted to the native soil. The slot width of the filter pipes can, in turn, be adjusted to the size of glass bead selected and therefore enables water to flow as far as possible unimpeded from the soil layers to the pump. A great deal of ground water has considerable quantities of dissolved lime, iron and manganese. Abrupt changes in pressure and, in some cases, temperature conditions in the area in the immediate vicinity of the well, coupled with the supply of atmospheric oxygen as a result

of reducing the water table and microbial activities mean that magnesium deposits in the supporting material are a well-known problem. This can lead to regular costly well cleaning and regeneration measures. If these are not carried out or are carried out too late, this can cause irreparable damage to the well. As laboratory experiments have proven, using glass bead with a smooth surface can make it far more difficult for deposits to build up and to settle in the annular space. Extending cleaning intervals results in a lower financial outlay in maintaining and operating the well. The additional costs for a well using glass bead instead of gravel or sand represents between 5 and 10% of the total building costs. If you offset these additional costs of building against the anticipated savings to operate and maintain the well, the profitability of using glass bead is guaranteed, particularly in view of an expected service life for a modern well of 30 years.

The acoustic Geo-Scanner: An innovative development for the industry of construction and mining machinery The successful implementation of construction projects and energy-efficient and quality-oriented extraction of mineral resources in unconsolidated soft soil depends on a precise knowledge about the shape and properties of soil layers. Foundation of constructions as well as mineral deposits, e.g. of fossil energy resources, industrial and construction minerals, are mostly found in the younger sediments of the upper earth crust, which consists of layers of cohesive (clay, silt, coal) and non cohesive (sands, gravels) materials. Both the stress deformation behavior and the hydraulic properties of these sediments are significantly different. In particular, the cohesive sediments, such as clays, influence the technical feasibility, economic viability and overall success of a construction or mining project considerably. In mining operations one of these layers is the goal of extraction while surrounding layers are considered as overburden or waste rock. These so called hanging wall and intermediate layers are non unproductive and therefore have a highly negative effect on the economics of the mining project .Usually exploration work has to be executed to get information about the underground conditions. The conventional technologies provide only selective or spot information and do not supply values of quality distribution within the deposit or the effectiveness of compliance with a given horizon in the underground. The exploration is always a crucial factor in the trade-off between efficiency and safety of the project. In many construction and mining sites a project accompanying inspection of the real subsoil conditions is not or insufficiently possible. The use of large open pit mining equipment such as bucket wheel excavators, any kind of dredging equipment as well as pile foundations in civil engineering are examples. To address these issues the Department for Surface Mining and International Mining at the Clausthal University of Technology

has developed a system based on an acoustic principle - Geo-Scanner - for online exploration of soil. The integration of this acoustic device at construction and mining machinery shall optimize machine design. This leads to an increase in economic and energy efficiency and environmental protection at construction and mining projects.

Detectino The Glassy Ground Every year, digging causes millions of Euros worth of damage to buried supply lines because in many cases no site plans are available. To avoid these costs, the multi-sensor detection system DETECTINO was designed by the Clausthaler Umwelttechnik-Institut GmbH, the University of Frankfurt Institute of Geoscience, the machine building company ProKasro and the Detectino GmbH. Since 2007 the consortium is working on this versatile, cost-effective mobile device which is able to identify buried supply lines in the ground using a DIN-based object-type-key. In addition using differentiated GPS, the location and depth of the lines will be determined and plotted into existing cadastral maps with accuracy in the range of centimeters.

Detectino The requirements (ground radar antennas, metal detectors and electromagnetic probes) are installed on a mobile platform that is small enough for supply line detection on footpaths. The sensor system is connected to a standard PC which transmits the measured data to a data base where they are processed by new computer intelligence technology and mapped into a virtual image of the area‘s underground down to a depth of 4 meters. Because of the fact that this system operates differently from conventional systems in an online mode, the operator can see the results live in a user-friendly 3-dimensional visualization and navigate with mouse clicks through the underground. So on the one hand it leads to the possibility to perform earthwork without damage, on the other hand it leads to a quality control for laying supply lines according to regulations and respectively to complete cadastral plans. The described requirements were particularly challenging in this project: non-contact sensing, location accuracy in the range of centimeters using differentiated GPS and provision of position and depth information which can be used to update existing mapping and support 2D or 3D display in online mode.

Pic. 3: Radargram analysis with computer intelligence technology

Possible target groups for this type of system are:

• verification or completion of existing maps,

• companies that install supply lines,

• ability to narrow down hazard zones to eliminate or minimise damage to existing underground structures during digging,

• electricity, water, sewage, gas and communications network operators,

• availability of a database which contains topographical information and existing supply line networks.

• the insurance industry, • companies that are responsible for digging up, repairing or installing new lines, • local government and other agencies

with a main interest in: • more efficient resource planning (personnel and equipment) based on knowledge of the situation in the underground,

The development phase and initial field trials show that the Detectino system, which uses the latest mechatronics technology, IT and geophysical sensors, meets the requirements profile, and the use of the device will soon be offered as a service. Excavation damage and its costs can thus be significantly reduced and implementation of effective planing on-site will lead to a huge increase of efficiency by using the system Detectino.

• a mechanism to disable digging equipment when it comes too close to lines that have been detected, • efficient (fast), cost-effective survey of critical or unknown areas to assess risks (leaks, flaws, etc.),

LiebherrLH 120 C material handler Specially designed for the movement of bulk materials, the Liebherr LH 120 C material handler makes its first public appearance at the 2010 “Bauma” trade fair. Within Liebherr’s extensive material-handling range, this is an entirely new purpose-built design.

LH 120 C MATERIAL HANDLER In response to the continual increase in bulk material handling worldwide, Liebherr has adopted a new approach for the LH 120 C, based on an innovative concept. The new machine, weighing approximately 135 metric tons, is the result of a development process that takes practical material handling requirements into account. To emphasise the new development principles that it incorporates, a new LH designation has been adopted for machines in this series. A new design, the high-performance LH 120 C is a versatile, cost-effective material handler and therefore an interesting alternative for dockside work as well, where cranes with a low level of mobility are still being operated in many cases. The Liebherr LH 120 C material handler is powered by a 400 kW (543 hp) Liebherr diesel engine. The square layout of the crawler-track undercarriage gives the machine, which weighs 135 metric tons, its high level of stability.

The LH 120 C’s multi-circuit hydraulics and its Liebherr diesel engine have been matched together for optimum results. Lower engine speeds together with hydraulic components and hoses of generous cross-section keep fuel consumption to a minimum. By the systematic use of modular assemblies, both the basic LH 120 C and its attachments can be ideally matched to operating requirements in specific situations. As a result, material handling capacities are high, but costs per ton remain low.

Pic. 1: The new designed LH 120 C

As on the current generation of Liebherr crawler excavators, the LH 120 C is equipped with Positive Control multi-circuit hydraulics, an efficient, high-performance system for maximum reliability and rapid load handling cycles.

A high proportion of inhouse production is a guarantee of reliability Liebherr components, including the engine and the hydraulic pumps, are specially designed and rated for material handling work, and ensure extended operating life and maximum economy.

Issue 01 | 2010



Pic. 2: The new design of the LH 120 C

Functional machine design, wellplanned ergonomics Special attention has been devoted to the machine’s design in order to optimise its functions while retaining well-defined, brand-specific styling features. The LH 120 C represents a new standard in the user-oriented design of large machines, and with its strong brand attributes sets itself apart effectively from competitors. Equally close attention was paid to ergonomics during development of the LH 120 C. All parts of the machine can be reached easily and safely by the steps provided. The LH 120 C also has an entirely new cab that sets even higher standards in interior space and operator convenience. Windows of generous size provide the best possible view of the work and surrounding areas. The cab is so spacious that two persons can be accommodated in comfort. All the controls are conveniently located within the operator’s immediate action radius. A new touch screen using an intuitive control principle provides a rapid display of all relevant operating data. Another feature of this new control concept is that the pedals have been kept clear of the driver’s field of view.

Servicing points such as the central lubricating system, hydraulic fluid level, engine oil etc. are neatly laid out and easy to reach. The fuel tank on the right is exceptionally large, so that lengthy work sessions can be undertaken before refuelling is necessary. The fuel tank has its own integral access steps for easy access without any unnecessary increase in the width of the superstructure.

Among the notable features contributing to Liebherr’s high safety standard are the strongly built, convenient access platforms and ladders. The cubic body panel outlines make the engine compartment easy to reach in safety, and provide a roof under which maintenance work can be carried out even in poor weather. Large maintenance flaps with an electro-hydraulic opening mechanism make servicing work even easier on the LH 120 C.

Innovative SL 750 EiControlPlus Shearer Loader

Technology with Human Traits

The developed innovative Eickhoff shearer loader is the global solution to safe and highly efficient mining of the worldwide most essential energy raw material, the coal, in landscape-saving underground longwalling. A completely newly developed automation package targets the power of three Formula 1 racing cars to the coalface while avoiding collisions with the surroundings.

Eickhoff SL 750 EiControlPlus Shearer Loader Nowadays, a machine of this rating is capable of mining up to over 1 million tons of coal a month! Given the harsh mining environment, such production rates impose significant challenges on the‚ pilot‘ of the mining machine. Up to recently, the machine operator being only equipped with a radio control, had to operate the machine with all its functions and, like the pilot of an aircraft, navigate the mining system three-dimensionally through the deposit to be extracted. Dust, rockfall, humidity, noise and constraints to the operator‘s vision are all grounds for the users‘ demands for far-reaching automation of the mining process. Hence the machine is expected to automatically orient itself as far as possible to the boundaries of the coal layer and to execute production autonomously. With the automated Eickhoff SL 750 EiControlPlus shearer loader it is possible for the first time to realize the idea of an automatic longwall operation where men can focus on monitoring functions in secure and unencumbered surroundings. This leading-edge machine is equipped

Issue 01 | 2010

with capabilities of ‚seeing‘, ‚hearing‘ and ‚feeling‘ which, all in all combined, are skills only human beings used to be capable of, and thus represents a genuine revolution. The newly developed Eickhoff SL 750 shearer loader is currentily considered as the smartest mining machine worldwide. The machine state information, the monitoring information on the surroundings and the collision hazards of the mobile machine, and the information on the position of the mining system relative to the deposit boundaries is detected by completely newly developed, linked sensors. Algorithms evaluate the sensor data and generate control information therefrom. The navigation system imparts the machine a sense of orientation in the naturally formed coal seam. The shearer thus reacts by itself to the continual changes of the underground plant requiring adaptation of far over 1000 hinges and articulations on every single machine pass.



Pic. 1: Schematic overview

Eickhoff EiControlPlus is subdivided into logical partial systems which are the haulage automation for the motion sequence of the machine and the extraction automation for controlling the extraction height and the three-dimensional direction of the mining motion. The haulage automation automates all motion sequences along the face during the extraction pass and includes haulage direction and speed, changes in direction, conveyor load protection, collision warning and avoidance. The extraction automation controls the position of the cutter drums such that the mining system autonomously follows the deposit boundaries, thus avoiding unnecessary extraction of undesired surrounding rock.

control tasks in the highly stressful surroundings of the machine and can focus, from the mine control centre, on monitoring and optimization tasks for the system.

One essential feature of the system is the powerful and transparent communication structure between the machine and the mine control centre via which all relevant information is transferred online through redundant and compatible communication paths.

This ground-breaking innovation is the result of a fruitful cooperation between research and industry. Young innovative engineers and highly specialized seniors bring in their skills to achieve a long dreamt-of goal.

This unique holistic approach to shearer loader automation brings about considerable advantages in terms of sustainable extraction of raw material, and of hard coal in particular. The Eickhoff SL 750 EiControlPlus shearer loader is therefore at the forefront of a machine generation which will enable fully autonomous mining systems in the future. The operators will then be relieved from the active

This obviously goes hand in hand with environmental and resource protection: Selective mining saves over 1 million tons of CO2 a year since less surrounding waste rock needs to be conveyed to the surface over several kilometers on belt conveyors and through shafts. Thin seams which are nowadays often unrecoverably left behind in a given deposit und thus lost forever, can now be mined again in fully automated operations. This concerns the majority of the global hard coal deposits.

Cooperation partners are the machine builder, Eickhoff Bergbautechnik GmbH in Bochum, the mining company, RAG - Deutsche Steinkohle, and the Institut f端r Maschinentechnik der Rohstoffindustrie (IMR) of RWTH Aachen with its spin-off for industrial radar technology, the INDURAD GmbH.

Operations in Switzerland – from drilling Sedrun 2 shaft to operate with TIMDRILLING


he development of the Thyssen Schachtbau GmbH (TS) Sedrun branch (TS-ZNL Sedrun), which led directly to the setting-up of the Swiss-based TIMDRILLING Joint Venture, has once again demonstrated that full commitment and dedication at individual and team level can drive a successful marketing venture in a new country. From drilling Sedrun 2 shaft to operate with TIMDRILLING Thyssen Schachtbau’s activities in Switzerland commenced in 2002 and since then the company has been successfully involved in raise-boring and preventersupported core drilling work and other specialist mining projects. There is no doubt that the high point of these operations was the sinking of the 800 m-deep Sedrun 2 shaft, which was completed within 12 months using a shaft boring machine. Some of the ­planning, transport and installation work required for the permanent shaft winding system was undertaken in parallel with the shaft sinking and was then completed after the shaft t­ ouched bottom.

Issue 01 | 2010

In order to provide real hands-on support for the tunnelling operations and to carry out specialist civil engineering and shaft construction work in the Alpine regions, most notably in Switzerland and its neighbouring countries, three project partners – namely Implenia BAU AG (created by the merger of the two Swiss construction companies Zschokke and Batigroup), Thyssen Schachtbau GmbH and ICOS of Italy – got together to set up the TIMDRILLING project group on 06.12.2006. The common strategic objective is to develop the TIMDRILLING Joint Venture into a stand-alone company by 2010.


TRANSFER OF TECHNOLOGY Market entry with the sinking of the Sedrun 2 shaft and installation of the permanent heavy-duty winder After lengthy preparations and negotiations the contract to sink the 800 m-deep Sedrun 2 shaft was awarded to the Sedrun II Shaft Boring Consortium in March 2002. This contracting group comprised RUC (South Africa), TS (Germany) and OESTUSTETTIN (Austria). A pilot hole first had to be ­drilled with an HG 330 raise-boring machine before the VSB VI shaft borer could be brought in to excavate the shaft to a diameter The VS8 VI grits its teeth to of 7.0 m. The sinking broke through to the level of the new Gotthard tunnel in June open the shaft out to 7.0 m. 2003, an achievement that was due in no small measure to the excellent support and (Photo: Employees TS Group) cooperation provided by the client, namely the TRANSCO ­tunnelling consortium, which was responsible for the dust extraction, drainage, debris clearance and materials supply services. TS had already supplied and installed the heavy-duty winder that was to be used for the sinking operation. The work subsequently needed to fit out this system as a heavy-duty shaft winding installation, and the first follow-on contract for the servicing and commissioning of this machine, provided the basis for long-term operations in Switzerland.

Commercial conditions for contracting companies working in Switzerland Companies wishing to engage in business activities in Switzerland first have to meet the following conditions: • Set up a branch office • Arrange for entry in the commercial register • Register with the taxation authorities (for capital gains tax and VAT) • Apply for residence and work permits for company workers

The branch office, which was first based in Zollikon, was entered in the commercial register of Zurich Canton in April 2004. The office subsequently moved to Sedrun (Graubünden ­Canton).

Another requirement for commencing operations in Switzerland is that all deployed workers must be paid in accordance with the collective bargaining agreement for the Swiss construction


TRANSFER OF TECHNOLOGY industry (LMV). While employees’ wages and salaries are taxed locally from the moment they start working in Switzerland, existing social security arrangements between Switzerland and the Federal Republic of Germany allow any pension insurance established in Germany to be retained for a period of six years. Once the first of the Thyssen Schachtbau employees had exceeded this time limit at the end of 2008 those concerned switched over to the Swiss pension insurance scheme on 01.01.2009. This also ended all BBG responsibility (German Mining Employers’ Industrial Liability Association) for these workers, this role then being taken over by the SUVA (Swiss Accident Insurance Fund), a company under public law that is responsible for statutory accident insurance in Switzerland. These changes, which were a legal requirement, also indicate that the TS branch office in Switzerland is gradually developing into ‘real’ Swiss company. The conversion to an independent subsidiary is planned for the end of 2010.

Mining expertise in big demand in the ‘land of the tunnel builders‘ A large number of tunneling and specialist civil engineering projects, most of which involved work for Alptransit Gotthard AG, have been carried out since operations commenced in Switzerland in 2002. The initiative first developed by TS has in turn been taken over by the Sedrun office and TIM-DRILLING. In addition to exploration drilling in the Faido and Sedrun sections of the Gotthard base tunnels the current ­scope of operations includes: • Preventer-supported rotary percussive and core drilling work for preliminary exploration of the tunnel drivage • Rotary percussive and core drilling without a pressure closing system • Conventional and mechanised shaft sinkings, mainly for tunnel and hydro electric works • Materials and heavy- load transport tasks, installation and operation of vertical and inclined conveying installations

• Installation of infrastructure and supply systems for tunnel construction projects • Injection work for strata sealing and reinforcement

In addition to the above activities the permanent Joint Venture TIMDRILLING will be providing the following specialist civil-engineering services as part of its longterm remit: • Raise-boring • Micro-tunneling • Ground freezing

The TIMDRILLING head office is at Sedrun in Switzerland.

TIMDRILLING project portfolio and future prospects TIMDRILLING is able to draw on TS‘ expertise in shaft-sinking and drilling along with the specialist civilengineering knowhow of Implenia Bau AG, with the Italianbased ICOS company bringing valuable experience in micro-tunnelling and ground-freezing to the overall group portfolio.

TIMDRILLNG‘s current activities are mainly focused on core drilling and percussive drilling work for the excavation of the Gotthard base tunnel. The geology, hydrology and geological make-up of these sections of tunnel are extremely complex and heterogeneous in nature. Sophisticated tunneling techniques were needed to drive through the fault zones, steep and inclined stratification and extreme strata overlap encountered along the tunnel route, an operation that posed a real challenge for the tunnel construction engineers.

Preliminary drilling was carried out during the drivage phase for better geological reconnaissance and in order to verify, confirm and/or modify the existing prognoses. Thanks to recent advances in drilling and strata-injection technologies tunnelling engineers now have access to preliminary exploration and strata reinforcement tools that can be employed effectively as the drivage advances. TIMDRILLING‘s future not only lies in drilling and injection work in the challenging environment of the Gotthard base tunnel but will also focus on raise-boring and shaft construction projects for the Alpine hydro electric industry.

New Sandvik universal button-bits for drilling big blast-holes with tophammers G

reat versatility, simple choices, rational inventories, higher penetration rates, straighter holes, longer bit life and lower energy consumption. These are the benefits Sandvik promises when rock-drillers change to RT300 UNIFACE, a new and exceptionally versatile series of threaded button-bits from 51-152 mm in diameter. Thanks to the use of one super-grade of cemented-carbide throughout and one universal face design per sequence of bit diameters, the user need now choose only the best button shape (Spherical or Ballistic) and best skirt design (Regular or Retrac) in order to obtain the best bit for the rock formation in question. As the leading component in the production chain, the drill bit plays a vital role in project advancement and must be chosen skillfully and decisively. Today this is hindered by a bewildering array of drill bits in the market, which can make it very difficult for users to choose exactly the right bit for the rock conditions. For any given bit diameter, some manufacturers can offer up to ten or more different designs. Not only does this make it hard to choose the right bit for the job, it also requires the ‘tailored’ bit to be changed whenever the rock conditions change, if optimal drilling is to be maintained. For years Sandvik has been trying to clear this minefield by consolidating more features into fewer drill-bit models in order to widen each bit’s range of application. Hardness and toughness, two normally mutuallyexclusive properties, are just two examples of such features. Now the firm has announced a double breakthrough. The first is XT48, a new grade of cemented-carbide that has the highest coexistence of hardness and toughness ever seen in one and the same tool, making it the world’s most universally applicable cemented-carbide for rockdrilling. The second is UNIFACE, a series of three new, patent-protected universal bit-face designs, one for Ø 51-64 mm bits, one for 70-96 mm bits and one for 102-152 mm bits. The Uniface design combines, synergizes and enhances, in a single drill-bit, diverse features that formerly necessitated two or more different models of bit. To qualify for the RT300-Uniface label, a drill bit must have both Grade XT48 cemented-carbide

Issue 01 | 2010

buttons (indicated by the suffix 48 in the ordering number) and a Uniface front. Expected to add value through higher productivity, better blasting results and lower rockexcavation costs, Sandvik says that RT300-Uniface bits will demonstrate quickly the practicality and benefits of greater universality.

Pic. 4: RT300 UNIFACE-Design: big button-bit-form “regular“

Choosing the right RT300-Uniface bit The guidelines for choosing the right Sandvik RT300Uniface bit are simple: Spherical buttons for very hard rocks; Ballistic buttons for less-hard rocks; Regular bit-skirt for solid homogenous formations; Retrac skirt for mixed, jointed or fractured formations. Thanks to the greater versatility of all Sandvik RT300-Uniface bits, however, their respective ranges of use are now much wider than before and the changeover boundaries are less strict.

New stepped retrac skirt balances wear and eases rotation All Sandvik RT300-Uniface ‘Retrac’ bits feature a patented new Stepped-Splines Retrac Skirt, which gives the best possible hole-straightness and retractability in mixed and/or and fractured rock formations. Since the long, splined skirt is stepped diametrically, bit rotatability improves immediately. In addition, any gage wear to the bit-face and bit-skirt is now more synchronous thanks to the steps on the skirt, and the skirt always has sufficient gage to provide good guidance in the hole. Not only does this improve the long-term rotatability of the drill bit, it also reduces wear, cuts energy demands and gives better quality holes.

TRANSFER OF TECHNOLOGY Why the RT300-Uniface design works best Sandvik RT300-Uniface drill bits combine the best features of the former Sandvik Flat-Face series of bits (for hard, abrasive rock formations) with those of the former Sandvik Drop-Center series (for mixed rock conditions and fractured formations). While the new bits exhibit characteristics of both designs, notably a combination of high, flat surfaces and deep recesses, they are much more than just a merger of the two designs. One striking characteristic is the high number of buttons in the face, as well as their more optimal placement and larger dimensions, which means that more hard-metal is presented to the rock more strategically and more efficiently. The foregoing features assure greater efficiency, higher productivity, straighter holes and less wear. As a result, more blast-holes of better quality can be drilled more economically in less time using less energy.

The 120 ton excavator with backactor equipment mines upper shell limestone with the tearing-/loading-initiation. In the MSV stone factory and its adjacent asphalt production, the upper shell limestone is processed into road construction material for the greater Stuttgart area and the nearby upper Rhine region Karlsruhe/Baden-Baden. Apart from the performance of the EX1200-6, particularly the customer support of the regionally responsible Kiesel-Ungeheuer company convinces the costumers. With the opening of its distribution and service branches, the company has just lastingly invested in the costumer service of the regions Stuttgart and North-Wuertemberg.

Shell Limestone for the Entire Region The Moensheim quarry, which has been in operation since 1978, is the lead plant of the MSW Mineralstoffwerke Südwest GmbH & Co. KG, a hundred percent subsidiary company of the Heinrich Metz company, with its headquarters in Stuttgart. The medium-size enterprise that is being lead by Albert Mertz almost in its fourth generation and with its own plants and shares, has been nationally active for over 80 years in the rock extraction, construction material production and logistics. Apart from shell limestone, the Mertz-offer also includes sand and gravel deliveries by road, train or ship from the Rhine valley, regional ready-mix concrete and asphalt

plants, as well as handling of old-building material. Thanks to the easy access, the approximately 300,000 tons of the MSW annual production from Moensheim reach a nationwide market: Located immediately at the A8 between Pforzheim and Stuttgart, Moensheim supplies the entire Stuttgart conurbation, as well as the upper Rhine regions Karlsruhe and Baden-Baden, due to the economic gravel return freights from the Mertz partner company. Currently the open wasting asset in Moensheim accounts for 4.5 hectar, in which upper shell lime stone with a depth of 25 -50 m is mined in wall heights of 5 meters, free of blasting. A large excavator with a backacter boom and a combined tearing-/loadingbucket is used, and two 60 ton steep-dumper trucks transport the rocks approximately 100 meters to the primary crusher of the 300-t/h processing.


TRANSFER OF TECHNOLOGY According to the leader of the operation Stefan Kunkel, the deposits in the current mining area will last for another one and a half years, after that the MSW will mine into the south direction, since the deposit still has a license for operation for the next 25 years. After that the cycle become considerably longer, which increases the demands to the cryptographic equipment extraction excavator and thus creates new possibilities for a tailored adaptation of the processing capacities.

Apart from the Hitachi steep-framed-dumper and the growing Zaxis- wheel loader family, which currently is mainly used for the reclaiming and dumps cultivation of non-metallic mineral processing plants, the German mining industry is mainly interested in Hitachi Hydraulic excavators with a charge weight of 50 to 120 tons. Hitachi responds to this by covering all typical service types in the German open pit mining with five well graded types from its quarry and mining program with its models of up to 800 tons charge weight. Furthermore, together with its delivery partner Kiesel, it adapts itself to customer-specific needs

Abb. 2: The broad reach of a maximum of 13.75 m allows for an economic tearing-maneuver without frequent relocations.

“After nine years and approximately 2000 operating hours, the service balance of our 120 ton machine rapidly deteriorated. Not only wearable parts and service costs, but only minor downtimes quickly have a negative effect on the organization of our one-shift operation.� This is how Stefan Kunkel outlines the change of demand, which at the end of last year led to a tender for new cryptographic equipment.

High-performance Dredger Concept Apart from making inquiries from its previous suppliers and service partners, MSW made inquiries from other suppliers in the 120 ton category, too. This also included Kiesel, which is the exclusive German partner of Hitachi. Parallel to the construction of its area-wide distribution and service systems in construction engineering, Kiesel has lastingly positioned itself in intensive project support of giant equipment in the mining segment.

Its specific construction and highstrength material make the shovel buckling resistant and thus enable full utilization of the high breakaway torque and tear-out force of the Hitachi EX 1200(according to ISO: 569 kN and 438 kN respectively). The 75SV2 system of the Kiesel equipping partner Esco, which is particularly designed for hard rock demands, is being used as sprocket system.

in the company organization, thanks to comprehensive options of its ZX- and EX models. This includes both loading-geometry of face-shovel and back-hoe dippers, down to the 50 ton model Hitachi ZX470, as well as special rock equipment for driver’s cabs and undercarriages. The Hitachi EX1200-6 is the smallest of the original Hitachi-EZ-mining excavator family. Since its introduction in 2005 Kiesel has already managed to place 8 machines of the 120 ton excavators, mainly in mining operations of the natural rock and chalk industry. Hereby, for the first time in Moensheim, a version of the current 6th generation back acter was applied. This version ensures a quick and highly productive loading operation through an optimized hydraulic function, while ensuring a long service life by targeted improvements in undercarriage, rotating assembly and drive chain. The new cabin and numerous improvements in operation and security, which further simplify operation and maintenance, also contributes to the improvements.

The Stuttgart branch of the regionally in charge KieselUngeheuer company, located in the 15 km far Leonberg, was in charge of the project. “The proximity and good communication and cooperation with all involved technical experts of the Kiesel- head office and Hitachi has certainly also been a decisive factor”. This is the resume of the operation manager Stefan Kunkel regarding the decision of opting for Hitachi for the cryptographic equipment in the plant. “We assume that, in case a quick service reaction ensures the availability of our mining excavators, this will further pay off in our operation.”

Since mining and truck loading in the MSW operation are often done on the same bed, the back acter excavator has been equipped with a cabin elevation, which offers the best view into the charging box through the 1.1 m heightened position of the driver and also simplifies the work at the wall. The plant management opted for a 6.2 m3 rock ripper bucket HDTL 84-S of the LOC-matic from the Alershausern

TRANSFER OF TECHNOLOGY The long-term basis for this has been created by Kiesel-Ungeheuer with high investments in Leonberg. It was only at the end of this year that an administrative and service building was inaugurated (approx. 6.000 m²), which concentrates the customer service and service capacities of the “Swabian” Kiesel-Ungeheuer branch. Beside the two locations in the Baden region, Karlsruhe and Mannheim, Leonberg is in charge of the regions Middle Neckar, Ostalb and Hohenlohe. Like all other nationwide branches and bases, which currently amount to 32, the new branch is fully integrated into network of the Kiesel-group. This ensures quick access to technical information from industry-sector and machine specific centers of competence on one hand, and on the other hand quick mediation of services for repair and maintenance or in the leasing area.

TRANSFER OF TECHNOLOGY CDE Ireland Ltd, Cookstown, North Ireland:

Customisation – The road to success

Pic. 1: Plant at Brooksby quarry


afarge are enjoying increased efficiencies at their Brooksby quarry following the introduction of a turnkey 180tph sand and gravel washing plant from Northern Ireland company, CDE Ireland. The plant has recently completed final commissioning and initial tests on the final products show a considerable improvement in quality when compared to the previous processing system being used at the site. Brooksby quarry is located near Melton Mowbray is Leicestershire and is a relatively new addition to the Lafarge portfolio having opened for business in 2007. The company has a licence to extract 300,000 tons of sand and gravel at the site, which at current capacity will allow for fifteen years production. The site will be progressively restored as extraction progresses to become agricultural land and a complex of lakes. The sustainability agenda is one that Lafarge take very seriously, as can be seen by their membership of seventeen wildlife trusts in the UK alone. While Lafarge are recognised as one of the most prominent names in the global construction materials market, their work in the UK is characterised by a commitment to local community groups and initiatives. “We rely on the local communities we serve in many ways” explains Andy Morris, National Production Manager in the UK with Lafarge. “Lafarge Aggregates have over 200 sites throughout the UK and the vast majority of these operations are managed on a day to day basis by people from the local area.” In addition to the 200 sites operated by Lafarge Aggregates in the UK, the Lafarge group also operate

Issue 01 | 2010

30 recycling centres processing a variety of materials including used rail ballast, concrete, asphalt, bricks and other demolition wastes.

A new solution Lafarge opened discussions with CDE about a new washing plant at Brooksby in late 2007 as a result of difficulties being experienced in processing the natural sand and gravel at the site. “The presence of clay in the raw feed was proving to be a problem with our previous processing system and this was having a significant impact on the quality and commercial value of our final products” says Andy Morris. A key factor in the selection of CDE to provide the solution to this problem was the customisation of the plant to the specific characteristics of the feed material. “We had gone down the off the shelf route before and it had not been successful” explains quarry manager at Brooksby, Will Laycock. “We set very high standards in relation to final product quality and these standards dictated that we sought to address the issues raised by the level of clay in the feed material.”


TRANSFER OF TECHNOLOGY Tackling this issue began with detailed materials testing at CDE’s laboratory in Cookstown. A substantial quantity of material was analysed in order to gain a clear picture of the typical grading the plant would be required to process. Once this had been determined CDE’s technical design engineers began to build the plant in order to produce the final products required by Lafarge – in this instance three aggregates and two sands (coarse and fine). Lafarge were able to provide CDE with detailed information on the grading of the final products that were required and from this the constituent parts of the plant were adapted to produce the required results. “Lafarge had a very clear idea of where they wanted to go and this helped enormously when we worked on the plant configuration” explains CDE’s general manager in the UK, Terry Ashby. Given previous experience at the site Lafarge were also

A key factor for CDE in accepting the performance guarantees requested by Lafarge was the level and clarity of information made available to them prior to the deal being done. “With access to the amount of information provided by Lafarge we were able to produce a large amount of data outlining what our plant would achieve” explains Dermot Murphy of CDE’s technical specification team. “Over the last seventeen years we have continually analysed plant performance and made design adjustments where required. We know what our plants are capable of and this confidence allows us to enter into agreements around final product specification such as the one agreed for the Brooksby plant.”

keen to include a number ofperformance guarantees with the order for the new washing plant. These covered gradings for all the final products and the lagoon water, as well as the final moisture content of the sand products. “The introduction of the performance guarantees on the plant was a critical factor for us in order to ensure that this considerable investment delivered the required results” says Andy Morris. “We were very impressed with CDE’s willingness to work with us on these guarantees. It demonstrated a level of confidence in their capability that is not the norm in our experience.”

Issue 01 | 2010

Plant set up The final plant configuration installed and commissioned by CDE at Brooksby quarry draws on a range of equipment from the CDE portfolio – hoppers, conveyors, ProGrade screens (both rinsing and dry sizing screens are included), the new AggMax attrition and classification system, and an A-series Evo-Wash sand plant.



Pic. 3: Stockpile conveyors

The feed material is loaded into the feed hopper which feeds a horizontal ground conveyor. From here the material is then transferred to a 28m static feed conveyor on its way to the primary screening phase. Due to the levels of clay in the feed material the conveyor is fitted with scrapers to ensure the belts stay as clean as possible, minimising spillage and ultimately increasing plant efficiency. “We offer a range of options to customers based on the individual requirements of the project” explains Terry Ashby. “The characteristics of the feed material are often the most significant consideration and by having a menu of options available, it ensures we can deliver high performance, high efficiency installations.” At the primary screening stage a ProGrade R211 double deck rinsing screen is employed and is set up with two polyurethane decks. The screen measures 6 m x 1.8 m (20 x 6 ft). The oversize (+ 40 mm) material is discharged into a concrete bay beneath the screen while the -5 mm material and waste water are sent to the EvoWash sand plant. The 5 mm to 40 mm material is delivered directly to the new CDE AggMax system. This unit combines the RotoMax attrition system and ProGrade dewatering screens in a compact configuration that reduces the space required on site to accommodate the plant. The RotoMax system has been introduced to specifically tackle the level of clay in the feed material. The model at Brooksby, the RX100, is one of three models available from CDE, with the largest capable of handling up to 300 tph. The RotoMax uses high specification components such as 118 chrome molybdenum blades, and has been designed to ensure maximum attrition of clay bound materials. The waste water from the RotoMax is sent to the EvoWash sand plant to recover any of the -5 mm material that made it past the first screening stage. Meanwhile, the scrubbed +5 mm material is delivered

Issue 01 | 2010

from the Roto-Max onto a ProGrade C-series de watering screen before being sent to the dry sizing screen via a 20 m static transfer conveyor. The dry sizing screen on this plant is a ProGrade D26 double deck screen measuring 4 m x 1.5 m (13 x 5 ft) and once again set up with two polyurethane decks. The dry sizing screen classifies the products into 5 - 10 mm, 10 - 20 mm and +20 mm aggregates which are transferred to stockpiles by three 20 m static conveyors. “The use of high specification components can be seen throughout the plant” says quarry manager, Will Laycock. “We had some fairly tight guidelines for CDE in terms of what we expected from the plant and in order to achieve this it was essential that we took the quality route. CDE have demonstrated the benefits of this approach in relation to product quality and efficiency and the results being achieved speak for themselves.” At the sand washing phase an A-series EvoWash sand plant is employed and produces a coarse sand and a fine sand. The specification of each of these sand products is covered by the performance guarantees discussed previously, as is the moisture content of both final sand products. The EvoWash sand plant has a 4 m x 1.8 m (13 x 6 ft) polyurethane screen deck which is split to allow for dual sand production. The slurried waste water and -5 mm sand product is delivered to the sump of the sand plant where it is then pumped through the first of two 500 mm cyclones. The material is then discharged onto the first side of the split screen where the aperture is set to allow the fine material to fall through to the sump with the waste water. The coarse sand product is dewatered on the screen which is powered by two 9 kw high frequency vibrating motors. This ensures maximum dewatering of the sand product, ensuring it is ready for market straight from the belts. The fine sand material is then pumped through the second of the 500 mm cyclones. The -63 micron material and waste water is removed via the cyclone overflow and


TRANSFER OF TECHNOLOGY sent to a ground sump in close proximity to the sand plant. This material is then pumped to on site lagoons. The fine sand product is delivered to the second side of the split dewatering screen where it is dewatered to approximately 12 % moisture content, once again ensuring it is ready for market straight from the belts.

Conclusion The new CDE washing plant at Brooksby quarry has succeeded in addressing the specific issues identified by Lafarge as being critical to plant success. The system successfully deals with the clay content in the feed material to produce the high quality sand and aggregate products demanded by Lafarge to uphold their reputation as a leading supplier to the UK market. In addition to this, the superior dewatering of the sand product in particular allows Lafarge to quickly turn their products into revenue. The installation and commissioning of the Brooksby plant was delayed following an unforeseen discovery of archaeological significant materials on site in mid-2008. “During preparation for the plant to be delivered to site we discovered materials later revealed to be from the Palaeolithic period” explains Will Laycock.

“This required some adjustments to the location of the plant and held up proceedings for a number of months while detailed investigations were carried out on site. Throughout this process and actual installation and commissioning we were very impressed with the project management approach adopted by CDE.” The new CDE plant at Brooksby quarry provides evidence of the success that can be enjoyed on projects such as this when a partnership approach is taken by both the customer and equipment supplier. A high level of consultation in the plant design process ensures the objectives of the plant are clear to all involved, maximizing the likelihood of an efficient, high quality installation.

TRANSFER OF TECHNOLOGY Zeppelin Baumaschinen GmbH:

The Construction Machine as a Networker!

Zeppelin and Caterpillar present innovative solutions in the area of Connected Worksite in Bauma G

arching, near Munich, in January 2010 (zep/AB). Already the demands of costumers of construction machines cannot be covered by the classical product and service range. There is a need for a systems solution, which offers the construction company a maximum of achieved work with a minimum of input, while maintaining a maximum of flexibility. The solution lies in the theme complex „Connected Worksite“ – a field in which Caterpillar and Zeppelin are innovation leaders. In connection with construction machines, “Connected Worksite” stands for integrated application of GPSdetermination of position, machine control, diagnosis and maintenance planning, consumption and productivity monitoring, as well as protection against theft. The sole application of these technologies yields significant productivity increase. Considering all machines, “Connected Worksite” mainly means the informational linkage of machine fleets with the construction site management and the central departments. It is only then that the full potential of the new technical possibilities can be tapped. Cat construction machines can already be equipped with the products „Product Link“ (tracking, equipment condition monitoring, plant maintenance planning), as well as Accu Grade and CGC Caterpillar Grade Control (machine control). Special products from the mining fields, like CAES or MINGEM complete the range of products. Furthermore, additional technologies like for example technologies

Issue 01 | 2010

for identification of objects and the remotely controlled application of construction machines are already being developed. A further focus is on the construction site and fleet management systems. The systems Minestar (applications planning) and Remote Operation (control station and remote control technique) are being applied in numerous mining operations. The new fleet management system Vision Link, as well as other systems for the complete automated application of construction machines are currently under development. The newest generation of the Cat construction machines is being prepared for the application with Connected Worksite products in the production line. In order to track and position the working equipment, e.g. a dozer, only a GPS receiver is needed, together with an angle sensor, which determines the inclination of the machine. Together with the information determined by the hydraulic cylinders and transferred to the computer, any position of the blade can be aimed at in a fully automated way. The fleet

management components, which are integrated in the machine, record the location of the machine via GPS and also record numerous situation data through sensors. The data transfer to the construction site control center or to the IT systems of Caterpillar and Zeppelin is either done by mobile phone networks or by communication satellites. In order to communicate with each other and with the control center, the machines on the construction site are equipped with radio data transmission, which enables a bidirectional transfer of data.

A system for all Machines Through its cooperation with Trimble, which is clearly the global market leader for positioning and measurement technologies, as well as for construction site management, Caterpillar has systematically aligned its own machines to Connected Worksite. Thus the company developed CTCT, a 50:50-Joint Venture, which comprises of the product lines GCS (Trimble) and AccuGrade and CGC (Caterpillar), respectively, in order to control construction machines through laser-, GPS- or tachymeter systems. Last year both partners established another joint venture company. From now on Virtual Site Solution takes care of the development of construction site and fleet management systems. The strategic partnership with Trimble enables Caterpillar to integrate special technologies into the machine development already at the design phase. Moreover, through the integration of Trimble products, Caterpillar also creates the prerequisites for costumers to manage mixed fleets with a system family. Thus the construction site and fleet management systems of Trimble can both

Issue 01 | 2010

process the machine data of Caterpillar and Non-Caterpillar machines, and hence the costumers are not forced to use parallel systems from various manufacturers for their machine management. Furthermore the construction site and fleet management systems can transfer machine and performance data to the ERP systems of the costumers through standard intersections. Apart from the actual products, the competence in distribution and most of all in service, in connection with Connected Worksite solutions, are critical for the costumer. Together with the power spectrum of Zeppelin and Trimble, Caterpillar has unique offers. Its machine design, which already takes into consideration the integration of various technologies, combined with a service offer, which includes the required engineering knowledge, enables the costumer to achieve a maximum of work with minimum input and high flexibility. More information on the subject of Connected Worksite can be obtained by the visitor to the bauma 2010 at the Zeppelin and Caterpillar booth in Hall B6.

TRANSFER OF TECHNOLOGY Pic. 2: This is what it will look like – the new business complex comprising warehouse, workshop, training and seminar rooms and a generous vehicle hall are expected to be ready for occupancy in the second half of 2010.

New buildings – growth and service expansion require space “Our consistent growth demands additional space for development, administration and manufacturing. And we also require more space for our extended range of services”, says Wissing. Last year, despite the general crisis mood, the company started with building operations for a new business complex. The larger office, warehouse and workshop space and also the training and seminar rooms and a generous vehicle hall are expected to be ready for occupation in the second half of this year.

pControl is fitted with a functional jog dial. Augmented by intelligent input aids and options for individual settings, operation is quick and easy. The new colour display of the pControl is also optimal as a monitor for a reversing camera – saving space and increasing safety. The weighing intelligence of the p-series is located in the pBase – a new functional unit. Hydraulic pressure and tilt are measured here and weight is calculated and weighing data stored in the alibi memory. pBase communicates with the pSmart or pControl displays via CAN bus and can be calibrated via these.

New »pSerie« – modern wheel loader scales to meet present and future demands The new p-series wheel loader scales extend the range, adding to the WK50 series models that have been tested and proven in over 10 000 applications. The modern pSmart and pControl electronic displays are more compact and offer a new, ergonomic user concept. They can be calibrated to meet the Y(b) accuracy class under MID and optimised weighing methods ensure additional improvement when weighing whilst the loader is in motion. pSmart is a simple display and control unit with all the basic technical weighing functions for calibrated applications. It is easy to use since the scale guides the user with clear symbols and no text instructions are required.

TRANSFER OF TECHNOLOGY Pic 4: »pSmart« - the independent display and control unit with all the basic weighing functions for calibrated weighing.

The new p-series can naturally also be cost-effectively retrofitted to other wheel loaders and the complete display module, the printer and even the new pressure sensor are replaceable within a calibration period if necessary – without recalibration. Another novelty: the associated “pOffice” PC software. Weighing and master data can be exchanged between the PC and pControl using either USB stick, GSM, GPRS or WLAN. This also enables online linking of the scales for order processing. Consistently positive feedback by the first users confirms that the manufacturer’s objectives have been achieved: simple operation, better overview, faster working, accurate weights, up-to-date options, increased reliability.

Further novelties and developments Besides the p-series, visitors will also find information on numerous product improvements and extensions and other new developments such as the new DW-3 dumper scale for articulated dumpers. Compared to the DW-2 scale which remains on offer, the DW-3 establishes the weight of the load via measurement sensors on the swing axle already during loading. The loading status is shown to the driver of the excavator or loader via the green-yellowred colours of the connected signal light - to prevent overloading.

Service – everything under one roof for maximum customer benefit Since the founding of the company, the scale specialist has made “made in Germany” product quality and customer-oriented service expansion his guiding principle. The company can today offer its customers services ranging from assembly support and conformity assessment to customer and calibration service – all under one roof. Under the new MID certification, the scale specialist now also performs the “first calibration”*) of the wheel loader scales without a calibration officer – saving time and money. The calibration service has also been extended to four company calibration trucks on German

roads - to handle conformity assessment, calibration and re-calibration. “Calibration authorities previously handled the first calibration but these are increasingly doing away with their own standard weights. We are certified in accordance with the MID directive, allowing us to perform our own first calibration*)”, says Ludger Wissing. [*) technical term: “Conformity assessment”]

New partners in Peru, Romania and Bulgaria have recently been appointed distributors for the German manufacturer and the “DISA” company in Sarnen (Lucerne) in Switzerland is also now a distributor. Besides our 11-year-old branch in Italy, another subsidiary was last year established in Croatia. Registration of a further subsidiary in Sweden is currently under way and negotiations are in progress about possible representation in Turkey.

Further expansion of global distribution

Competent advice and customer-oriented service are our guiding principles both locally and via the agencies and branches abroad. Regular training and dealership conferences are held to achieve this goal, keeping technical and sales staff of all the partners technically up to date and also identifying and implementing improvement potentials through global exchange of information.

With agencies and branches in 38 countries, the company is also well placed in respect of global distribution. Together with its distribution partners, the scale specialist currently serves dealers and customers throughout Europe and in many other countries in the Americas, Australia and China.

BSW Stahl-Nebenprodukte GmbH simplifies the flow of information Efficiency in handling electric furnace slag of weighing data – with the Pfreundt mobile weighing technique and WLAN-data transfer.

Pic. 10: BSN weighs the electric furnace slag “EOS” directly while loading on the Pfreundt wheel loader scale, which ensures optimum loading and saves time.

The Baden steel works (BSW) in Kehl at the river Rhine are one of the highest-performance steel works in the world and produce over 2 million tons of concrete steel and wire rod for Europe. It only takes four hours to turn steel scrap as initial raw material into the ready-for-sale product – a peak value. In marketing of its side products, BSW also focuses on high efficiency. The sister company BSW StahlNebenprodukte (steel side products), in short BSN is responsible for this task. It produces mineral material for the construction of traffic routes from electric furnace slag, which after all amounts to approx. 350,000 tons per year.

Electric furnace slag- a high-quality and versatile mineral material The electric furnace slag, which is being marketed in all established grain sizes by BSN as “EOS”, can be universally used. EOS can be used in road construction in all layers, i.e from the anti-freezing and ballast layer up to the asphalt coating. Furthermore the material is extraordinarily suitable for the hydraulic construction, as well as for road building and road coating. EOS can also

Issue 01 | 2010

be applied as filling material of gabions, which serve as noise- or visual protection. Hereby the usage of mineral construction material preserves natural resources. Efficiency of material and information flow is an important indicator in the BSN- factory premises. A few minutes after the weight note for the material – which is being loaded on the trucks by 5 wheel loaders - is printed, the materials and accounts department of the BSN administration is informed about the exact amount.

Mobile weighing technique saves time For over 10 years, the wheel loaders have been equipped with weighing systems of Pfreundt. Specific pressure sensors in the hydraulic actuator of the wheel loader register the weight of the bucket contents and transfer the measuring data to the WK 50-weighing electronics, which is located in the cockpit of the construction machine. Through an amount display the driver can load exactly as much material as the costumer wishes. Through this it is possible to effectively avoid both an overloading of trucks, as well as too high, uncalculated loading amounts, due to the fact that work is done “according to gut-feelings”.

TRANSFER OF TECHNOLOGY WLAN instead of memory card Up to a few months ago BSN stored the weighing data on an integrated memory card, which was handed over each evening and was read in and processed by the BSN administration the next day. A few months ago a modern and quick solution was developed in collaboration with the IT specialists of the BSW group. Daniel Baumgart, leader of EOS production with BSN says: “ Simultaneously with the print, the weighing data are sent via WLAN from the weighing electronics WK50 to the administration”

Increased efficiency and informational advantage With this solution the memory card can be omitted, which simplifies the operation, increases the transparency and creates the basis for a quick information flow from the wheel loader weighing scale to the company software for materials handling and financial settlement. It is not an issue that the data transfer is actually done in real-time: actually there is no need to be that quick. But the automated procedure of the handling of the weighing data saves both time and efforts. Furthermore additional information is available at a keystroke. Daniel Baumgart states: “ In bigger projects the colleagues in the administration, as well as we in the operation can immediately see how much material has been loaded in a 3000 ton order. With the incorporation of the mobile weighing technique into the company IT, BSN puts into practice not only a gain in efficiency, but also an information advantage.

TRANSFER OF TECHNOLOGY Metso Minerals (Germany) GmbH

Mobility on hold Stationary workaround prevents risky maneuvers in quarry: t the Kuhn Quarry near Waldhambach at the Pfälzer Wald Nature Reserve, granite and andesite have A been extracted to produce ballast for many decades. At the quarry, mainly granite is extracted for the production of ballast base and frost protection courses, though some armourstone is won, part of which are used for landscape gardening. In the natural fissures of the andesite, agates, for example, are formed, attracting the interest of dedicated mineral collectors.

A quarry facing big changes Since the physical partition of the fraternal company partnership in 2006, the quarry itself has been facing massive changes. Willi Kuhn and his son-in-law Stefan Kuhn, who has taken over management since the restructuring of the company, developed a new operating concept and set up a double separate production circuit. For this purpose, two large intermediate storage facilities with tunnels and metering equipment were set up. The aim was to maintain the operating cycles without any interruption – irrespective of whether the primary crusher is being maintained or whether one of the screens happens to be down in the modernized screening facility. Looking ahead and with the purpose of increasing productivity,

it was necessary to scrutinize the individual machine components. The aging stationary primary crusher had to make room for a mobile unit, to enable a more flexible extraction process. In 2008 the operators opted to invest in a mobile Lokotrack LT140 supplied by Metso Minerals, to which a mobile conveyor, the Lokolink LL, can be connected. Prior to this, the company had been able to convince itself of the efficiency of Metso’s second-largest mobile jaw crusher and then set itself the objective of more flexible

production with the new unit and above all directly at the pile of blasted rock. Previously two large excavators and two dumpers worked at the sites to extract the andesite and granite, requiring a total of four operatives. Thanks to investment in a mobile jaw crusher, the company hoped that it could save on three operatives as well as three large machines in the quarrying operation, which were in future to be freed up for overburden and backfilling work. This was initially a very expedient decision as one excavator operator can deal with operation of the Lokotrack at the same time.

Stationary feed for a mobile unit On account of the steep slope and sometimes difficult space conditions, following the acquisition, problems arose with the manoeuvrability of the primary crushing unit. “Especially at the transfer point between the Lokolink conveyors and the crusher, we caused severe damage when we moved the crusher ...” conceded Stefan Kuhn. The machine could not be as employed as flexibly as originally planned in the current extraction situation (opening up of the quarry to the approved final depth). The safety of the operatives and the machine were more important to the quarry operator. The company then invested in a large semi-mobile feed bin as a temporary solution and positioned it on an intermediate level of the quarry. With the LT140 below and the connected Lokolink belts, the primary crusher is initially set for stationary operation (Fig. 5). But that is to be changed in the foreseeable future: “Once the bottom floor has been reached in around one and half year’s time, the LT140 can fully unfold its full capabilities and feed the stationary belt via the mobile Lokolink belts from there,” Stefan Kuhn plans. Even today the two dumpers can’t supply the material fast enough to fully utilize the crusher capacity. The Lokotrack works in a single-shift operation and consumes just 35-40 l diesel per hour.

The belt weigher at the discharge conveyor measures the daily tonnage, which with hard granite, a full bin and a gap width of around 180 mm, totals around 450 t/h. Apart from the usual crusher tool changes, so far no significant repairs have been necessary. As part of the modernization measures, the Type 1351 Svedala machines operated since 1981 and 1985 are currently being replaced with a Metso HP300 cone crusher. The existing quarrying approval ensures long-term supply of the region with raw materials. It is therefore foreseeable that all mobile machines will get significantly more freedom of movement to permanently meet the company’s business goals.

GNSS, 3D and „smart“-drilling – A good team for more success in blasting!

Photo: Drilling the holes (Photo: Atlas Copco MCT GmbH)


rilling and Blasting plays a very important role in the production chain of an aggregates quarry. As the first step during the production it sets the stage for a successful production.

Are Errors inevitable? Good blasting can influence positively secondary breaking and ease of. During the process of Drilling and Blasting there are a few critical steps, of which some are of a technical origin, while others tend to be organisational problems: Thanks to modern laserscanning (face profiling) technology it is possible to get a detailed view of the face geometry. Therefore it is also possible to take actions in order to optimize the blast in terms of blasted volume, optimum burden and hole lengths. Nevertheless it is mandatory for a successful blast, that the design is transferred to reality very precisely. The first step is to mark the hole positions. The more complex a blast is, the more potential errors can occur (see figure 1).

Issue 01 | 2010

Normally tape measure is used to mark the hole positions. So it is clear the errors sum up and it is obvious to see that hole positions and hole separations may not be identical to the original blast design. Of course it also takes (sometimes a lot of) time to mark the hole positions manually. Since the quarry staff is mostly overloaded with work it is obvious, that lack of time also causes errors. As soon as all hole positions are marked, it is the drill rig operator’s job to drill all holes exactly the way they were planned. It is absolutely important that the holes are straight and do not deviate. However: it is also critical, that the holes have the correct azimuth. Drillers typically look for a feature, which is “far away” in order to correctly set up the rig’s boom and feeder, which inherently causes errors in the hole’s azimuth (see figure 2).



Fig. 1: Complex blast design with 3 rows and adjusted hole positions for optimum burden.

Table 1 shows the distances between planned and actual bottom hole point based on hole angle and hole length. Additional errors caused by deviating holes are not included. Additional problems occur, as soon as the holes show different azimuths, as shown in figure 3. Of course it is possible to determine actual hole positions by doing a post drill survey. It is also common practice to survey the drilled holes with a hole probe and check for any discrepancies between the blast design and the actually drilled holes. However: in case there are any differences the blasting engineer will not be able to achieve optimum fragmentation of the blasted material, since hole separations and burdens differ from the perfect setup.

Fig. 2: Azimuth errors caused by setting up the rig using a feature, which is “far away”.

Table. 1: Distances between planned and actual bottom hole depth based hole angle and hole length using the dollowing parameters: • Number of holes: 20

Of course not only technical, but also organisational reasons are causing problems: In case a hole cannot be drilled at the planned position, the drill rig operator has to choose a new position. It is mandatory that this information finds its way to the blasting engineer, so that he can change his blast design correspondingly. It is also important, that the information has a quantitative measure (e.g. hole has been shifted 50cm to the right and 30 cm back from the face). Especially if drilling and blasting is carried out by different parties (contractors), this is even harder to achieve:

• hole separation: 4m • Adistance to the remote feature: 500m

Better blast with the latest technology

System description

Over the past years there were both improvements in the survey technology (GPS/GNSS, LiDAR/laser) as well as in the automation of drill rigs.

At the beginning the face is scanned with a 3D laser. After that the blasting engineer designs the blast using Quarry6. The blast design (hole coordinates, drill angle and azimuth‌) is copied to a USB device and loaded to the drill rig. The drill rig itself carries two GNSS receivers and some additional sensors. Since the hole coordinates are in a global coordinate system (e.g. UTM) the blasting engineer does not have to mark the hole positions manually, the SmartRIG is guiding the rig operator to the planned positions. After selecting a hole, the rig is automatically setting up the boom and feeder with the correct angles, so that drill angle and drill azimuth fit the planned parameters and the rig operator can start drilling. While drilling, the rig is storing information like the hole start coordinates

Already 6 years ago, AtlasCopco intruduced the SmartRIG generation of drill rigs. These SmartRIGs can have GNSS receivers on board as well as several other sensors. In order to see the benefits of the combination of a GNSS equipped SmartRIG with face profiling systems, AtlasCopco MCT Germany, EPC Germany and geo-konzept GmbH set up a 4 month test project.

Issue 01 | 2010


TRANSFER OF TECHNOLOGY as well as the bottom hole coordinated based on the measured drill length, inclination and orientation of the boom. When the holes are drilled, the collected data can be imported into Quarry 6 again. The planned holes will be replaced by the measured holes from the rig. In this way the blasting engineer gets a detailed view of the drilled holes (hole positions, hole length, orientation‌) except for the deviation of the holes, which still has to be measured by using a hole probe. Example: Excavation of a new bench. The hole system has been tested in several blasts. One of these blasts should be presented in more detail: A new bench should be created in a granite quarry. Figure 4 shows the planned holes in a 3D view. As a fist step 154 holes with a total length of 890m are planned. The drilling bench itself is not very flat and is inclined in two axes. The first and last hole of a row have a different orientation than the other holes in order to get a good inclination for the new face. It was planned to achieve a 10% inclination for the new ramp. In combination with the huge number of holes and a changing drill pattern, it was obvious that this blast would be a good performance test for the system. Fig. 4: 3D view of the planned blast.

Issue 01 | 2010

Moreover it was not a perfect place for the reception of GPS signals, because the place was obstructed from the south. As a consequence there were GPS outages in the morning and in the evening for about 30 minutes. The problem could be overcome by adding GLONASS capability to the receivers.

Procedure A cross check of the hole coordinates from the rig and a post drill survey showed a correlation of better than 3cm (3D). All parties agreed that the system saved a lot of time, because the hole positions didn’t had to be marked manually. Not only the drill rig operator noticed, that it also saved a lot of time, that the rig set up the feeder in the correct way automatically corresponding to the blast design. Especially the first and the last hole of a row could be drilled quickly and very precisely. The only additional work for this workflow is setting up the GNSS base station every morning, which takes about 5-10 minutes. Future tests will show whether the base station could be replaced by correction data from a GNSS VRS network.


TRANSFER OF TECHNOLOGY As all information from the rig was saved, it was also possible to update the blast design in the software. The files were sent via internet, so even the blasting engineer saved time because he received all necessary information by email without having to drive to the quarry.

Additional benefits Additional benefits of the integration of GNSS are the documentation of the blast itself and even every single hole location. Therefore it is very easy to get answers to questions like “What’s the distance to the vibration monitors? What’s the distance to the nearest buildings?”.

Of course it also makes it easy to continuously update mine maps. Last but not least saving data this way offers precise accounting for quarries.

Result The blast was very successful. Blasted material showed good fragmentation and the ramp had exactly the planned inclination and is very even.

NEWS & REPORTS Bell Equipment

Bell Equipment leads the “GreEN Revolution” for Off-highway machines


long with its current range of Articulated Dump Trucks (ADTs), Bell Equipment will showcase its solution to upcoming European Off-Highway Stage 3b emissions legislation at Bauma 2010.

Bell will utilise SCR technology (Selective Catalytic Reduction) to ensure that NOx and exhaust particulate matter (PM) thresholds are maintained, while still ensuring maximum productivity and uptime for the customer. SCR technology will be introduced on all ADTs manufactured at Bell’s German assembly plant from 2011. Bell will continue to use Mercedes Benz 500 and 900 series engines on its range of ADTs. Mercedes engines have a proven track record offering maximum power with a very frugal appetite for fuel. Mercedes has also been using SCR technology on their on-road trucks for many

years now, and Bell is proud to pioneer this technology for the off-road market. SCR technology utilises an after treatment fluid, commonly called Diesel Exhaust Fluid (or DEF in America) or AdBlue. AdBlue consists of a non toxic Urea and water solution, which is stored in a separate tank. It is sprayed into the exhaust system and reacts with the exhaust gases in the catalyst. The net reaction produces inert Nitrogen and water vapour, both of which are common compounds in the atmosphere.

To minimise the impact to the customer the AdBlue tank will be large enough to hold four shifts worth of fluid. SCR technology also has the following advantages: • Up to 5% better fuel consumption, means reduced CO2 emissions; • It is compatible with Bio-Diesel; • Increased engine power; • Proven engine technology ensuring reliability and durability; • Proven technology used on road transport, so infrastructure is already in place – over 100 million kilometres have been done on road trucks with AdBlue and SCR technology; • Very little maintenance required; • No dimensional changes with Tier 3 engines, ensuring common global design of Bell ADTs.

Powered by Mercedes-Benz: Bell ADTs meet future emission regulation with proven engine technology.

Issue 01 | 2010


NEWS & REPORTS The SCR technology is reliable and offers many inherent advantages in Off-highway practice.

SCR vs. EGR (Comparison with EGR) Many other manufacturers utilise EGR technology for current emissions regulation. EGR (Exhaust Gas Recirculation) recycles exhaust gas back through the engine to reduce combustion temperature. This reduces the NOx levels; PM is reduced by a diesel particulate filter (DPF). EGR technology has the following disadvantages:

European Stage 4 legislation comes into effect in Europe in 2014, and at that stage all off-road manufacturers will need to comply with legislation to reduce both exhaust particulate and NOx levels. Bell Equipment’s solution will meet the new legislation while still providing the end user with piece of mind, by providing maximum operational efficiency, reliability and durability by using proven engine technology.

• EGR increases heat rejection which results in a lot of wasted energy; • Catalytic converter requires energy (heat) for regeneration; • EGR engines need low ash lube oils; • EGR engines need low or ultra low sulfur fuel; • A DPF requires periodic maintenance.

The Mercedes-Benz V-8-Engine OM 502LA powers Bell’s large models B45D and B50D.

Hyundai Heavy Indistries Europe N.V.

the European launch of Hyundai’s 9 Series excavator range at bauma 2010 A comprehensive range with advanced features and Hyundai’s operator-focused values! Hyundai’s long-anticipated 9 Series Excavators at Bauma in April 2010 will be the culmination of a long and detailed period of product planning, design, development and testing: The launch of the full range, from 1.6 to 50t, of Hyundai’s long-anticipated 9 Series Excavators at Bauma in April 2010 will be the culmination of a long and detailed period of product planning, design, development and testing for what Hyundai believes will set a new standard in operator satisfaction. In addition to several pre-launch activities, including some prototype and pre-production previews at international shows and events over the past 12 months, Hyundai has also introduced a selective feedback programme in Europe, beginning in January 2010, enabling operators to get hands-on experience and to provide valuable feedback to the company. The focus of attention at Hyundai’s Research and Development department in Ulsan, Korea, over the full design and development proces, has been centered on the machine operator. Every working component and system has been thoroughly analysed and assessed in the light of its impact on both the mechanical and functional quality of the machine with regards to the comfort and convenience of the operator, as well as durability and reliability.

Issue 01 | 2010

The guiding principle behind this approach has been not just to perpetuate Hyundai’s legendary reliability, but to create an environment in which the operator feels happy and gains both pleasure and satisfaction from working in an operator-rewarding environment. This aspect of operator productivity, as well as the wide range of followon benefits of all-round improved efficiency and costeffectiveness, will appeal equally to machine owners.

Core Product Values The three core operator-focused product values which Hyundai believes can help operators to take pleasure in their work are: operator preference, fast precision and lasting performance. And a fourth core value, intended specifically for the owners of 9 Series excavators, is the concept of the machine as a reliable and productive ‘profit centre’.



This whole new breed of excavators enables operators to adjust and set machine performance and comfort levels to their own personal needs and preferences. The preference nerve centre is the dashboard cluster, complete with a multi-function, 13cm (5 inch) colour LCD screen and toggle-switch. It provides instant access to a wide choice of functions and checks: a selection of power modes, work modes, maintenance checks, instant diagnostics and much more. Comfort level selection is given high priority, with operators now able to choose a fully adjustable air-suspension seat, and to set the arm-rests and joysticks to the preferred position and height. All -9 Series operators will benefit from having full control over the cabin temperature with the standard, high capacity air conditioning system, and also have a builtin radio/MP3/CD player at their disposal, with remote control, to create the ideal working atmosphere. Fast precision is the product of efficient power delivery and the finesse of the hydraulic system controlling that power. This is an area in which Hyundai has come up with a unique and innovative solution: the ‘Posi-Nega’ hydraulic system which is installed on midsized 9 Series excavators. This uncomplicated, and therefore reliable system, combines the controllability benefits of a sophisticated ‘positive’ system, with the servicing benefits of a technically less complex ‘negative’ system. The positive part controls boom and arm movements, with optimum power and speed, whereas the negative part feeds bucket, swing and travel functions when required. The variablevolume axial piston pump arrangement, with solenoid controlled valve block, provides extra sensitive control. In addition, the arm-in flow regeneration eliminates cavitation and permits smooth arm movements. Even the hydraulic track drives benefit from shock-proof stop-start functions for smoother ride and positioning.

The dashboard cluster with LCD screen is the preference nerve center of the 9 Series excavator. A clear and wide view on the jobsite is a key element for working precisely.

The 9 Series excavator cabin, a clean, comfortable, ‘stress less’ work environment.

But for Hyundai, there is more to precision than just excellent hydraulic response. The operator’s view on the worksite has been further improved by using a new, narrower tube section for the cab structure, with low-cut and larger windows. Furthermore, the -9 Series cabin allows the operator to concentrate fully on the job at hand, in a ‘stress less’ environment, thanks to special low noise upholstery and low vibration cabin mounting.

Easy access, long service intervals and fuel efficiency contribute to profit.

Issue 01 | 2010


NEWS & REPORTS The third key element in defining operator pleasure is the machine’s overall performance, which is dependent on the available power and on applying that power effectively. Heavy-line -9 Series excavators use the latest, well-proven Cummins QSB six-cylinder diesel engines, which meet Stage IIIA emission requirements and which, together with a re-designed and updated CAPO (computer aided power optimization) system, provide optimal power allocation. The best example of this is auto boom-swing priority, a smart function that automatically and continuously finds the ideal hydraulic flow balance for the boom and swing motions of the machine, in real time. Profitability is almost a natural follow-on, if the other three parameters are right. Hyundai machines have always been noted for their reliability, ensuring high earning power and good resale value. This reputation is further enhanced by applying a number of fuel efficient systems and functions, like one-touch and auto-deceleration and a fan clutch system that increases the engine cooling fan speed only when necessary, greatly reducing energy loss and thus saving fuel. Other factors which have a bearing on both reliability and maintenance costs include the use of high quality components, extended maintenance intervals with centralized lubrication points, long-life filters, lubrication and wear-parts. To help owners safeguard and monitor their investment, Hyundai is introducing its GPS technology based remote management system: ‘Hi-Mate’. The system facilitates machine tracking, tracing and monitoring anytime and anywhere, thus providing owners with a time saving advantage. With Hi-Mate it is now possible to remotely

diagnose equipment, check operating hours as well as fuel level, and pinpoint the exact position of the owners’ Hyundai fleet.

Vision Announcing this major new product initiative, Mr. J.W. Hwang, Managing Director of Hyundai Heavy Industries Europe says, “With this project for operator friendly equipment, we underline our company vision for building a better future. A vision that today has more value than ever before. At Hyundai, we have taken the long view, and invested in technology which will see our machines take a major step forward. We believe that the adoption of the four strong core principles in our design philosophy will show through in the products and establish a benchmark which others will want to emulate.” “To fully appreciate the value of the whole -9 Series package,” adds Michel de Weert, European Marketing Manager, “you need to see it in the flesh, and in action, to understand just how much operators will love these machines. We are expecting this range to set a new standard in operator appeal, and become the preferred choice for the discerning owner”. “It will all be on show to the world at Bauma – and with more besides.”

World premiere of Giant:

Wirtgen presents biggest Surface Miner 4200 SM at bauma 2010


1980, Wirtgen GmbH built the first surface miner for the mining of minerals in open-cast deposits. Today, Wirtgen is the market leader in this segment, offering a technically mature product portfolio for opencast mining that has been tried and tested in operations around the globe. The latest machine in this product division is the large 4200 SM: the mining giant will be presented to the industry specialists in Munich as a world premiere. With a total weight of over 200 tonnes and a length of over 30 metres, the huge machine is the heaviest and longest exhibit of the entire Wirtgen Group exhibition stand.

4200 SM: maximum performance in large-scale opencast mining At bauma, which is the leading trade fair in the industry, the 4200 SM will represent the successful surface mining division of Wirtgen GmbH that comprises three machines for opencast mining in different performance classes. Surface miners from Wirtgen offer cutting widths ranging from 2.20 m to 4.20 m and cutting depths of between 20 cm and 83 cm. Wirtgen is the only manufacturer covering a scope of performance ranging from 100 tonnes to 3,000 tonnes per hour. This high measure of productivity is attributable to the miners’ efficient cutting technology plus a wealth of experience gained in three decades of application technology. Productivity is clearly also the hallmark of the new 4200 SM: the miner is a high-performance machine suitable for

Issue 01 | 2010

mine operators and customers in large-scale open-cast mining whose goal is to achieve an annual mining capacity in soft rock of up to 12 million tonnes while wanting to make full use of the benefits offered by Wirtgen’s selective mining technology that enables cutting, crushing and loading in a single working pass.

The panorama cabin of the 4200 SM offers an excellent view for permanent monitoring of the work processes from the operator’s platform. Being isolated from the vibrations and noise emissions of the engine and cutting drum, the cabin offers a high degree of operator comfort when working in 24-hour shifts.


NEWS & REPORTS 4200 SM in the Cloudbreak Mine in Western Australia: the most powerful Wirtgen surface miner is operating in iron ore, achieving daily production rates of 12,000 tonnes per shift.

The 4200 SM is available in two different configurations for operations in either hard or soft rock. For applications in soft rock with unconfined compressive strengths of up to 50 MPa, the 4200 SM is equipped with a 4.20 m wide cutting drum unit with larger cut-ting diameter, thus permitting a cutting depth of up to 83 cm. The largest Wirtgen miner can alternatively be equipped with a drum assembly offering a cutting width of 4.20 m and a cutting depth of 65 cm for applications in hard rock with unconfined compressive strengths ranging from 30 MPa to 80 MPa. The heavy-duty machine is equipped with a 16-cylinder diesel engine from Cummins, making it the ideal candidate for a wide range of applications as its power of 1,194 kW / 1,623 PS offers tremendous reserve capacity. Generously dimensioned tanks offering capacities of 2,900 l for diesel and 10,000 l for water additionally increase the miner’s uptime.

A two-stage conveyor system with 1,800 mm wide primary and discharge conveyors and optional discharge conveyor lengths of 12,000 mm or 16,000 supports the surface miner’s impressive cutting performance of up to 3,000 tonnes per hour. The conveyor’s large slewing angle of 180 degrees, flexible height adjustment and variable conveyor belt speed ensure smooth loading of large transport trucks even in restricted space conditions.

NEWS & REPORTS Kleemann GmbH

World firsts with extra power:

the new generationKleemann impact crushers At the Bauma 2010 trade fair, Kleemann is exhibiting two completely newly developed, contractor-class mobile impact crushers The foremost goal during development was to ensure maximum power while simultaneously providing the highest economy and availability.

The secret of success: improving the flow of material through the entire machine. „To attain genuinely better performance, we were not satisfied with just addressing individual components. The key to a real increase in performance is the redesign of the flow of material – encompassing all components,“ says Thomas Kühnle, Head of Technology at Kleemann.

Issue 01 | 2010

Material flow concept is key to highest performance values The new material flow concept consistently prevents narrowing of the material stream, and the system widths of the conveyor elements „open“ in the material flow direction. This allows performance values to be attained that are unmatched in these size classes. For the smaller of the two machines, which has a crusher inlet opening of 1100 mm, input capacities of over 350 t/h are measured. For the larger system, which has an inlet opening of 1300 mm, input capacities of 450 t/h and higher are attained.

NEWS & REPORTS Direct drive: Versatile and economical The outstandingly economical performance is made possible in part by the extremely efficient direct drive with which both machines are equipped. A latest-generation diesel engine transmits its power almost loss-free via a robust fluid coupling and the V-belts directly to the flywheel of the crusher. This drive concept also enables enormous versatility, as the rotor speed can be adjusted in four stages. For example, the machines are equally well suited to use in quarries and in recycling, where the input material is often highly inhomogenous, particularly for difficult processing of construction waste.

Innovations in the individual components Of course, the most important new feature for the individual components is the heart of the machines, the completely newly developed impact crushers of the SHB series. They feature many convincing new detailed solutions that are unmatched: from the hydraulically actuated crusher inlet in extremely robust heavy-duty cast design to the optimised, steeper inlet angle to the new blow bar fastening system – these all have a positive effect on availability. In addition, they have an innovative fully hydraulic crushing gap adjustment that can be operated easily and in mere seconds from the operating panel. The crushing gap adjustment, zero gap measurement and overload protection functions are cleverly integrated into one compact unit. The crusher bypass was also given a complete overhaul. An optimised flow of material ensures that the input material, which is screened off by the extremely effective double-deck pre-screening unit and cleaned, is continually

moved past the crusher, even at high screening output. One critical effect of the restriction-free material flow is the considerably reduced wear, particularly in the areas of the crusher outlet, crusher bypass and discharge chute. However, the crusher is not the only new feature. For example, there is a newly designed feeding hopper which, supported by a load-dependent control, enables continuous loading. Critical advances have also been made in the shape and drive of the discharge chute. Only its added discharge capacity makes it possible to manage the higher volumes of material in the critical outlet area of the crusher. Another extremely important feature for capacity and quality is the new classifying screening unit, which has been enlarged by 45% and which enables a closed circuit and thus the production of a defined final grain. Even for sieving grains up to 35 mm, the machine can make use of its full capacity without reducing the input volume. A swivelling return conveyor enables optional discharge of oversized particles to the waste rock pile.

Fast changeover times, high availability In addition, the development process placed special emphasis on high availability and fast changeover times. Thus the hopper walls of the input unit are now not only lifted hydraulically, but also locked automatically by a new bolt system – without the need for any additional manual intervention. The bottom line: with these two machines, Kleemann is starting a new chapter in terms of both capacity and economy.

In a class by itself in terms of capacity and availability: the new generation of mobile Kleemann impact crushers.

Liebherr-wheel loader L 586 2plus2

New block handling version! wheel loader L 586 2plus2 Liebherr’s largest wheel loader with hydrostatic transmission, the L 586 2plus2, was introduced at the 2007 ‘Bauma’ and has already given excellent results in a variety of applications all over the world. At the 2010 ‘Bauma’ Liebherr is exhibiting a block handling equipment package for this model, intended specifically for the handling and transport of large stone blocks. This newly developed version of the L 586 2plus2 is for example ideally equipped for the loading and transport of heavy granite or marble blocks. When blocks of stone intended for further processing are extracted, it is preferable for them to be as large as possible. The maximum weight that the L 586 2plus2 can carry is influenced by operating conditions, but depending on lifting height and the stone block’s centre of gravity, it is possible to handle blocks weighing at least 24 metric tons. The Liebherr block handling package consists of various purpose-designed equipment options, including various stone fork patterns, shovels and a special tearout tooth. This extensive range of equipment enables the wheel loader to be closely matched to a variety of operating

conditions and loading tasks. For maximum flexibility, the block handling package includes a quick-change device for the working attachments. The new block handling equipment package means that companies operating in this specific area can now benefit from the quality and the many system-related advantages of Liebherr’s wheel loaders with hydrostatic transmission. These advantages include fuel consumption that is as much as 25 % lower than wheel loaders with conventional transmission, an effectively wear-free service brake, minimum tyre wear and safe, convenient single-lever control. Since steep gradients are encountered in stone quarries, the braking effect of the hydrostatic transmission with its automatic self-locking action makes a major contribution to safety, and also avoids overheating of the brake system and axles.

Liebherr LB 16 large rotary drilling rig

Liebherr-Werk Nenzing GmbH


completes lower end of range LB 16 large rotary drilling rig At the 2010 ‘Bauma’ Liebherr is introducing the LB 16 large rotary drilling rig, an additional model that rounds off its LB series. This series entered production only three years ago, and is now available in five sizes with torque ratings between 16 and 36 mT. The LB series is an ideal adjunct to the existing Liebherr LRB range of combined piling and drilling rigs. The LB concept is derived from Liebherr’s many years of experience in deep foundation applications, and takes into account the toughest demands now placed on modern rotary drilling rigs. All LB models are special-purpose machines for demanding drilling tasks. They are suitable for a wide range of applications including Kelly, continuous flight auger or double rotary drilling, and for use with soil mixing equipment.

Exceptional performance and equipment features The new LB 16 rotary drilling rig has compact dimensions and is therefore also ideal for use where space is limited. Its minimum gateway and transport width is only 2.5 metres. It has a rated torque of 16 mT and is intended for a maximum drilling diameter of 1.5 m and drilling depths down to 34.5 m. For cased holes, a casing oscillator for diameters up to 1.2 m can be operated.

A notable technical advantage of the LB 16 is the rope crowd system, with a retraction force of 20 t. It offers the user maximum performance and reliability even under the toughest soil and operating conditions. Unique technical features of the LB 16 are its robust leader design and exceptionally load-resistant kinematic layout with generous system width. They give this large drilling rig significantly higher stability and strength than other machines of similar size. Design and construction of the LB 16 prepare it for the most severe demands ever encountered in practice. For the user, this not only means greater performance potential but also reduced wear, so that the operating life of the machine is automatically prolonged.

Versatility for increased efficiency, low-cost transport The compact dimensions of this smallest member of the LB series of machines make it possible for the basic machine and the leader to be carried as a single unit. The overall length for transport purposes is only 15.5 metres and the width 2.5 m. A folding leader-base option further reduces transport length to only 13.5 m. This speeds up and simplifies machine repositioning and makes work on the construction site more flexible. The LB 16 can also be carried with the rotary in position, without exceeding the transport width of 2.5 m; the weight is then in the region of 47.5 t. If working height is limited, the LB 16 can be converted to operate with a shorter leader. Overall height is then 12.5 m. With a 3-fold Kelly bar in use, the machine can reach drilling depths of as much as 16.5 m. Like all Liebherr piling and drilling rigs, the new LB 16 is equipped with the well-proven Litronic control system. Based on the latest CANBUS generation, this control system comprises not only programmes for the various drilling methods but also servicing and troubleshooting information in a clearly laid-out form. A remote maintenance modem and a process data recorder to document the work carried out are available as plug-in modules.

will be used to build the Hyderabad-Bangalore motorway


he first motorway connecting the cities of Hyderabad-Bangalore will be built using MB crusher buckets, equipment that stands out due to its unique and unmistakable characteristics. The motorway will be approximately 600 km long, with 3 lanes in both directions, and will represent an important change in India as the country will benefit from a fast and greater flow of communication, transportation and commerce networks, which up until today have been carried out mainly by sea. MB S.p.A., the undisputed world leader in the production and sale of crusher buckets, views this new project as a positive turning point for India, which will progress from both a commercial and economic standpoint, all in full respect for the environment, an issue that has top priority in the philosophy of the Breganze-based company (currently in the process of obtaining the ISO 14001 certification). It is no accident that its buckets work using the hydraulic system of the excavator they are fitted up, and, unlike traditional crushers, offer significantly reduced transportation and waste disposal costs, thus allowing inert materials to be recycled.

by their performance, and this because it relies on a prestigious company, in constant growth and with highly qualified expertise, a company that handles the needs of its customers with a high level of commitment.

In order to build the motorway, it was decided on the BF120.4 bucket, which will be used to produce the stabilized pavements every 50 km. The peculiar feature of the BF120.4 is that it is the only piece of equipment capable of reducing the size of crushed granite from 20 to 4 cm, thus making the job easier and more versatile.

MB S.p.A.: a name, a philosophy, a company that has managed to assertively position itself on the market, demonstrating that its products are high-quality, safe, versatile, long-lasting, innovative and 100% Made in Italy.

India will thus become familiar with the high quality of MB products, and will have the opportunity to see them in action, evaluate them and be completely satisfied

“We are extremely optimistic on the successful outcome of the motorway that will connect the cities of Hyderabad and Bangalore, both extremely excited to try out our highly technological, Italian-made buckets and to obtain a new communication line that we are sure will be appreciated by the Indian country�, stated Guido Azzolin, Managing Director of MB S.p.A..

Bodybuilders help Volvo flex its hauler muscles


auma gives Volvo the chance to demonstrate a range of innovations in the articulated hauler sector. One of them is the Hauler Chassis programme, which provides bodybuilders with a modular system that forms the basis for several other superstructure versions.

Bauma 2010 will see the international launch of the Hauler Chassis concept – a Volvo Construction Equipment programme that is designed to open up a world of application possibilities. While the load body is a traditional ‘attachment’ for articulated haulers, several other effective hauling solutions can now be easily developed. Using E-Series articulated tractors, with a standard or extended frame as a base, bodybuilders, often in cooperation with Volvo dealers, can create a wide range of off-highway specials, such as hook lift, container hauler, concrete mixer, construction tractor, pipe carrier, wood chipper or timber transporter – satisfying customers’ needs in different segments. For example, a Volvo pipe carrier,

Issue 01 | 2010

together with a crawler excavator-based Volvo pipe layer, can be a perfect solution for the oil and gas industry. The Hauler Chassis programme gives bodybuilders the appropriate support throughout the design and build phase. Volvo has developed a dedicated web-portal, where drawings, diagrams and technical instructions to perform suitable work on a hauler chassis can be found. There is also clarification about legal responsibilities, warranty conditions and the possibility to contact Volvo experts for additional help if needed, so that the complete vehicle can perform its task safely, efficiently and economically.



Total hauling solutions In addition to the A25E Hauler Chassis, with a hook lift, the Bauma 2010 exhibition in Munich will also feature three other Volvo articulated haulers with ‘traditional’ load bodies. On Volvo’s outdoor area, two medium platform haulers, the A25E and A30E will be joined by one large platform machine, the A40E FS, featuring ATC – Automatic Traction Control. The Full Suspension (denoted by an ‘FS’ in the machine designation) provides good off-road performance, allowing a fully loaded hauler to travel at much higher speeds, appearing to float over rough ground without bouncing, significantly increasing operator comfort, which, in turn, increases overall productivity. When travelling empty, return trips are also substantially faster due to the smooth, stable ride even over rough conditions, further decreasing the overall working cycle time. The Volvo FS system features automatic levelling and stability control. The system constantly monitors the

Ausgabe 01 | 2010

position of the axles, with the help of sensors, adapting the suspension to suit the changing conditions, absorbing rough spots and keeping the machine level while travelling, loading or dumping. Vibration levels are also considerably lower than in conventional machines, and by providing a smoother ride, operators experience less fatigue, so efficiency increases greatly.

Automatically efficient The Automatic Traction Control system fitted as an option to the A25E, A30E and A40E FS haulers on display in Munich, ensures that Volvo’s 6x4 and 6x6 capabilities are properly used in all, especially the most unforgiving, conditions. With the ATC system, the operator’s influence on tyre wear, fuel consumption, component life, steering



ability and overall machine productivity is significantly reduced. Operators benefit from operating the machine in the safest possible way by keeping their eyes on the road at all times. The system chooses the optimal drive combination, automatically engaging or disengaging ‘dog clutch’ type differential locks, when needed. As a result, the machine keeps traction, mobility and is easier to operate – in all conditions. These are just some of the reasons why more and more customers, everyday, choose Volvo articulated haulers for applications where top class productivity, reliability, manoeuvrability and flexibility in the toughest conditions are the main decisive factors.

Innovations Crushing Technology In field of the crushing technology BHS is specialized on vertical shaft impact crushers and mills. The BHS machines are operating to the great satisfaction of many aggregate producers worldwide in order to improve the shape of the final product, to produce crushed sand or for selective crushing applications.


t bauma 2010 BHS-Sonthofen will exhibit its product range in the field of mixing and crushing technology. Several innovations in both fields will be presented to the market for the first time.

Innovations Mixing Technology The twin-shaft batch mixer is the main product in the field of mixing technology. Several thousand BHS machines are in operation worldwide. The production of concrete is the most frequent application. The following innovations will be presented: • The new series of mixer type DKXN. It has been especially developed for ready-mix producers using mostly high-slump concrete. Due to several design measures the prices can be calculated more attractive than for the other twin-shaft mixer series. • For mixing applications, which need higher shear forces, a special twin-shaft batch mixer has been developed. Each shaft is equipped with double mixing tools and the drive system allows a much higher mixing speed. This mixer is mainly suitable for the production of modern concrete recipes in the field of pre-cast concrete production (e.g. UHPC) or for special applications like landfill sealings. • As mixing accessory the new impulse controlled lubrication system will be presented. It allows an automatic greasing of all mixer sealings at the end of each production shift. The lubrication can be released by a control panel giving an adjustable grease quantity.

Issue 01 | 2010

An innovation at bauma will be a semi mobile plant with a BHS Rotor Centrifugal Crusher. The plant is equipped with feeding hopper, conveying belts for inand output and a control system. It can hydraulically be lifted up and down in order to place it on any standard lowbed trailer. The plant is an attractive solution for operators with changing locations. Also in export markets there is a growing demand for such a compact unit, which can easily be integrated into any existing facility.

Exposed Application Examples Another main focus on the booth of BHS will be the presentation of practical applications examples. In the field of mixing technology several concrete columns will be presented, which were made from various demanding modern recipes (e.g. colored concrete, SCC, steel fiber concrete …). In the field of crushing technology several transparent columns will be exposed. They are filled with crushing examples from various kinds of rock. For a better analysis the individual screening fractions are placed in layers on top of each other. The examples demonstrate the wide range of applications of BHS machines in mixing and crushing technology.

DEHACO´s ONGOING DEVELOPMENT - THE NEW DE-DUST NANO With the DE-Dust Pico Dehaco B.V. became second at the elections for the prestigious “Demolition Awards”. This by the company itself developed mini nebula cannon is particularly suitable for smaller demolition and renovation activities indoors. Dehaco has not been idle in the meantime and now officially presents the DE-Dust NANO, Pico’s big brother. Visitors of the demolition trade fair (Sloopwerk Vakdagen) in Houten could already observe it. Once again Dehaco competently reacts to the demand from the market; the development of new products and evolving already existing products for the demolition and redevelopment branch for asbestos. Dehaco improved the DE-Dust product series of nebula cannons once again. Now the Pico standard has been equipped with a program switch in order to be able to adjust the water consumption between 4 and 8 litres per hour. To some extent the large models have been improved, so that this machinery can be delivered in different models easily.


The new type of nebula cannons, which has been showed at the recently held demolition trade fair (Sloopwerk Vakdagen) in Houten, is Pico’s big brother and has been designed for the demolition of larger rooms indoors or for the demolition of small objects in the open air. One only has to connect the NANO to the water and power supply. This type does not need compressed air. The water consumption can be adjusted up to 80 litres per hour. The NANO can be easily taken along, it weighs 19 kg. An important characteristic of the atomization head is its large opening, which reduces the risk of clogging to zero. A force pump is also not required, which results in a reliable and simple solution. The first product series will be available shortly. For more information about the DE-Dust Nebula cannons please visit our website:

HAZEMAG Dinting Loader EL 160


HAZEMAG Dinting Loader EL 160 D端lmen, February 2010: HAZEMAG dinting loaders of the EL 160 series are very successful in the coal mining industry all over the world in the field of maintenance and repair of underground galleries. The compact design of the dinting loader EL 160 permits its application in narrow spaces. For crushing rock fragments five hydraulically driven impact chisels are integrated in the bottom of the box-type bucket. As an alternative to this bucket the machine may be fitted with a hydraulic rammer for especially difficult operating conditions as e.g. for loosening parts of rock with a high compressive strength or for crushing large-scale rock plates. On the BAUMA Fair in Munich HAZEMAG is going to present the newly-developed version of the EL 160 LS with a gun-mount for blast hole- and anchor bore hole drillings. By using modern construction- and production technology as well as high-quality materials this new gun mount achieves a low dead weight and, at the same time, a

very high stability. This allows high drilling speeds at a high precision of the boring. In case of the exhibit the drilling tasks are carried out with a hydraulic drifter in a rotarypercussive drilling method up to a diameter of 52 mm and a boring depth of 2.4 m in hard rock. Due to the quick and exact positioning of the drill boom towards the starting point of the boring very good drilling results are achieved. A hydraulic quick changing device on the drill boom permits the conversion to a side tipping bucket for loading the previously blasted rock on the available conveying system within a short time. The use of modern hydraulic components coupled with a powerful cooling plant permits a reliable and failsafe operation in areas with high ambient temperatures. In accordance with the respective country-specific legal requirements the machine is equipped with electrotechnical components which allow the application in mines with methane gas.

HAZEMAG - Clay crushed by a Horizontal Roll Crusher! Clay crushed by a Horizontal Roll Crusher Dülmen, February 2010: With the feed material being Clay -Sticky, Wet and Hard-with a feed size of 500 mm ( 19 5/8 inch) to be crushed to a final size of 0-60 mm ( 2 3/8” minus) was the challenge, These are the operational conditions the HAZEMAG horizontal Roll Crusher FB 0708 is facing a prepared to conquer. At the end of 2008 Peißener Tonprodukte GmbH & Co. KG was in the process of commissioning its new materials preparation plant for clay. The clay is used as an additive in the cement making process and has to have a specific size. During the crushing process, extra attention has to be paid to the stickiness and moisture content of the feed material. In addition, the feed material ( 500mm or 16 5/8” x 0) has to be guaranteed to be reduced to 0-60 mm (0 x 2 3/8”) taking into consideration that the material hardness is 160 MPa (23,200 PSI) and impurities of limestone can reach 200 MPa ( 29,000 PSI).

Issue 01 | 2010

The customer was finally convinced of solving this crushing challenge because of the many advantages / solutions the HAZEMAG Crusher was offering. The Light and Compact Design combined with easy installation and inexpensive setup and material feeding were obvious. Today the HAZEMAG SOLUTION is one of the main plant components – assuring the company a successful operation. The Horizontal Roll Crusher type FB 0708 consists of two main subassemblies: • Crushing Roll • Chain Conveyor

The arrangement of the crushing roll above the chain conveyor makes the chain conveyer both the feeding conveyor and the discharging conveyor –All In One! Due


NEWS & REPORTS to Single direction material flow, oversized material can be crushed and blockages or non crushable feed occurs (ie. metallic tramp metal), the blockage can be cleared by simply reversing the feed direction. At the same time horizontal crushing accommodates feeding at grade or with only small ramps but usually WITHOUT feeding hoppers. Even when hoppers are desired, as was the wish of Peißener Ton, feed with trucks can be easily accomplished without concrete pads or expensive ramps. The light and compact design makes it easy to transport, set-up and commission these crushers on site. No special construction work such as concrete foundations is necessary. Only two 8 hour shifts were needed to setup this plant, ready to run!

The plant was handed over to the pleased customer after fulfilling a performance test of 200 metric tons per hour plus reaching all other parameters such as final product size etc. At BAUMA 2010, HAZEMAG is displaying one of the bigger brothers the FB 1111. This crushers’ technology can be used for Gypsum, Potash, Coal and many softer minerals at feed sizes of up to 1500 mm 5 Feet) with throughput rates of 1000 tph. Make it a point to stop and see Hazemag at BAUMA 2010 in front of Hall 2. Also, don’t forget - if you have to crush harder stone, our impact roll crushers can be used for the hard stone, also. These same machines are crushing granite and gneiss in the Switzerland along with the hard rock tunnelling application which is commonly know as NEAT (New Alp Transit / St. Gotthard).

Flexible screening

HAZEMAG - VARIOwobbler® Always the perfect setting !

Always the perfect setting – the HAZEMAG VARIOwobbler® Dülmen, February 2010: HAZEMAG & EPR GmbH in Dülmen introduces the HAZEMAG VARIOwobbler®, which represents a new generation of wobbler feeders for prescreening operations in crushing plants. An outstanding feature of this wobbler is the facility for infinitely varying the gap between the individual shafts by means of an effective hydro-mechanical control system, in order to determine

Issue 01 | 2010

the screened product granulometry at the touch of a button and without the use of any tools. This system allows for quick and flexible reaction to changing requirements and ensures that the feeder is always adjusted to the correct setting. Such a system is of particular interest under the following circumstances: • When weather conditions fluctuate, there can be changes in the H20 content, and consequently in the


NEWS & REPORTS screening behaviour of the material to be processed. The gap setting adjustment facility provides the optimum means to compensate for any such variations during the screening operation. • In quarry operations, the characteristics and properties of the recovered material – for instance, the proportion of actual suitable material, and thus the screening behaviour - can vary. In such cases, the optimum setting can be selected similarly at the touch of a button. • If market or customer demands and requirements change, i.e. should a coarser product be desired, the gap setting is simply widened, and likewise, if a finer product is called for, the gap reduced appropriately.

In a conventional vibrating screen, to undertake such changes involves considerable time and effort in changing the actual screen grates. The new VARIOwobbler® screens can replace a conventional screen in a crushing plant without any problems; they can be designed as single- or multi-stage machines, according to whether or not existing machine height differences need to be overcome. Thanks to the various stages, the material flow is agitated several times, facilitating the downward flow of the fine material from the upper layers of the material bed and separating these fines from the coarse material. Additionally, the fines - which often contain a high percentage of the

material‘s moisture content – are removed prior to entry into the crusher, avoiding the potential danger of clogging and caking in the actual crusher. The wobbler itself is not affected by sticky material. All the shafts of the VARIOwobbler® are individually driven. The use of these roller screens leads to increased operational safety and to a reduction in energy and operating costs: Thanks to the horizontal material flow on the roller screen, the downstream crusher is fed evenly and uniformly in a controlled manner. By separating the fines, the load on the crusher is reduced, resulting in less wear and reduced power requirements, and even possibly to the introduction of a reduced crusher size. The HAZEMAG VARIOwobbler® has been designed for the following applications: • Types of material:

Limestone, Marl, Clay, Coal, Natural rock, Minerals with sticky inclusions, etc.

• Feed size:

0 – 1.500 mm

• Separation:

15 – 150 mm

• Capacity:

up to 2.500 t/h

• Width:

up to approx. 3,5 m

NEWS & REPORTS Atlas Copco Underground Rock Excavation


New Minetruck MT42 – for superior productivity in underground haulage!


tlas Copco’s new Minetruck MT42 represents our next generation of underground trucks. This high-speed 42 tonne articulated truck has been designed to maximize productivity as well as provide increased safety and excellent operator comfort in underground haulage applications. The Minetruck MT42 is available now in Scandinavia and Canada and will be launched globally in 2011.

The Minetruck MT42

Proven performance

The Minetruck MT42 is powered by a fuel efficient, low-emission Cummins QSX15 520 hp EPA Tier 3/Stage IIIA engine, coupled with proven drivetrain components, delivering reliable performance and high speed on ramps. The transmission has eight forward and two reverse gears and features a self-diagnostic system for rapid troubleshooting.

An extensive, 12-month field test at Boliden’s Garpenberg mine in Sweden proved the capabilities of the Minetruck MT42, while also winning praise from the operators. “The Minetruck MT42 has a lot of power and with its four wheel drive it can go anywhere,” says Stefan Olsson, a truck operator for mining contractor Euromining.

Operator comforts in the standard ISO ROPS/FOPS certified cabin include an air suspended forward-facing seat, a clear, multifunction display monitor, air conditioning and a trainer’s seat. The operator’s sound exposure is below 80 dB (A) in the cabin. Front axle suspension further contributes to operator comfort, while also allowing greater speeds on mine roadways.

Issue 01 | 2010

Fellow operator, Jan Lehtinen also appreciates the driving qualities of the new Minetruck. “The MT42 is able to go round corners that other trucks would need to back up again and again to get round. Both backwards and forwards, it takes corners smoothly,” he says. “Some trucks can lose traction on inclines, especially when they are not carrying a load or in wet conditions. This is no problem for the MT42, you just drive straight on.”

Advanced productivity The articulated steering increases maneuverability and allows agile cornering, while the dump system can discharge a full load in just 13 seconds. Rear facing cameras, one backup camera and one loading camera covering the box, complement the operator’s view from the cabin.

The truck’s brakes are spring applied, hydraulic released (SAHR) – the safest in the industry. SAHR brakes eliminate the need for a separate parking brake, are low maintenance and provide extended service life. A service bay on the side of the truck allows easy access to filters, valve blocks and service points for daily maintenance and the cabin can be hydraulically tilted to expose the engine bay.

EVENTS AACHEN INTERNATIONAL MINING SYMPOSIA AIMS 2010: Third International Symposium “Mineral Resources and Mine Development” 26 and 27 May 2010 Aachen, Germany No minerals – no future! Nobody denies that the world will continue to need minerals in the future. But are we prepared to secure tomorrows supply with critical raw materials? Which minerals will be needed, what will be their long-term demand and where are the deposits to accommodate these requirements?

Questions that will be discussed at the third international Symposium “Mineral Resources and Mine Development” within the scope of the conference series “Aachen International Mining Symposia”. Organized by the Institute of Mining Engineering I, RWTH Aachen University, in cooperation with the RAG Deutsche Steinkohle and the European Association of Mining Industries (Euromines) it is sponsored by European Technology Platform on Sustainable Mineral Resources (ETP SMR), Becker Mining Systems AG, Hilti and Sandvik. About 50 experts from Europe, Australia, Canada, India, Japan and the United States, representatives of European Ministries and Geological Services as well as CEOs from international companies are invited to present their point of view to around 400 participants. At a plenary session the European Technology Platform on Sustainable Mineral Resources (ETP SMR) will provide an interesting insight into the EU Commision´s Raw Materials Initiative (RMI). As sustainable management of mineral resources starts with the state-of-the-art extraction of raw materials, presentations at the Symposium also focus on practical issues such as the physical development of mining projects covering modern production methods as well as preparatory and supporting issues . Against the background of the imperial city of Aachen both the show at the venue and the themed Dinner Party will offer ample opportunity to get in contact with customers and colleagues.
