About Siwertell

A solid brand and name With over four decades at the forefront of sustainable dry bulk handling, Siwertell offers some of the highest capacities and levels of efficiency, safety, longevity and environmental protection available, along with low operational and maintenance costs. Siwertell drives industry standards by offering benefits for every dry bulk market. All Siwertell equipment combines high capacity bulk handling with efficiency, reliability, and minimal environmental impact. Siwertell’s initial success grew from the development of a unique and patented counter-rotating inlet feeder for screw-type conveyors. It was designed and developed by two Swedish inventors, Olle Siwersson and Gunnar Tell, who combined their surnames to give the brand its famous name. The development of a highly-efficient screw conveying device was one of the most significant events for the dry bulk handling market. The potential for ship unloading was soon recognised and in 1974 the Siwertell ship unloader was born.



Since then Siwertell has maintained its position at the forefront of market-leading developments. Today Siwertell offers ship unloaders, road-mobile ship unloaders, ship loaders, mechanical and pneumatic conveying systems, and complete plant and terminal designs.

Dry bulk materials

Handling virtually dry bulk cargo


Ninety percent of global trade is carried by sea and a major part of this is the dry bulk industry. It transports much of the raw material needed for power generation, industrial processes, construction and food production. Siwertell technology provides efficient, environmentallyresponsible and safe handling for these valuable bulk commodities.


Alumina requires careful handling because smelting costs can be dramatically increased if the percentage of dust is raised by damage incurred during cargo operations. Siwertell unloaders outperform all alternative systems traditionally used for alumina unloading, causing minimal cargo degradation and offering high efficiency. Siwertell loaders are well-established as a preferred system for alumina loading. 4



The global demand for biomass is mainly driven by power plants burning coal and biomass to achieve a carbon neutral operation. Siwertell unloaders are ideal for these co-firing operations, because they can handle both coal and biomass without any adjustment. Biomass is a hazardous material – Siwertell biomass unloaders therefore incorporate safety elements originally developed for safe sulphur handling.


Siwertell delivered its revolutionary screw-type ship unloader to the cement industry in 1975, bringing efficiency and clean operations to the market. In 1980 it introduced an 800t/h unloader, which remained the industry standard until the late 1990s. Siwertell now offers cement unloaders with capacities of up to 1,500t/h, reflecting the use of larger vessels for cement transportation.


ecause of the enormous quantities involved, dry bulk materials require efficient loading and unloading systems to keep vessel turnaround times and overall handling costs to a minimum. Some dry bulk commodities are hazardous to handle, with the potential for fire and explosion, some can be polluting, while others require careful handling to minimise cargo degradation. Siwertell’s totally-enclosed systems offer very efficient, clean, high-capacity dry bulk handling for virtually all dry bulk trades. With no spillage and hardly any dust creation, they offer unrivalled environmental performance. They also lead the way in addressing all the safety and degradation issues raised by specific cargoes.


The international coal trade is largely concerned with power generation and steel production. Growing demands have progressively pushed up the size of vessels used with the need for ever higher loading and unloading capacities. Siwertell has always anticipated the market and now offers unloaders operating at 3,000t/h; almost a tonne every second.


Grain and similar agri-bulk cargoes require high-capacity handling systems that treat individual grains gently without causing any degradation. Siwertell unloaders were developed from improvements to screw conveyors used in the grain industry, so they are absolutely ideal for the purpose. Highcapacity, highly-efficient Siwertell unloaders handle grain at up to 1,800t/h.


Sulphur is a corrosive, pollutive and dangerous cargo. Siwertell is the only manufacturer offering a safe, totally-enclosed unloading system that addresses these important issues. No spillage and minimal dust creation protects the environment. Stainless steel components minimise corrosion. The Siwertell 4S safety system minimises the risk of fire and explosion, while extinguishing and containing them if they should occur. THIS IS SIWERTELL



Focusing on the

environment Siwertell sets unrivalled standards in environmental protection by delivering four key elements: no spillage, minimal dust creation, low noise levels, and some of the highest efficiency rates on the market. Siwertell technology easily exceeds the requirements of all current environmental legislations for handling dry bulk material. 6


Regulations at all levels rightly seek to ensure cleaner operations, while portspecific requirements for clean and quiet procedures can place direct pressure on operators to improve their environmental performance or face closure. The environment is a key consideration in all Siwertell design processes. Siwertell’s totally-enclosed systems offer the best solutions for operators needing spillage-free dry bulk cargo handling, with virtually no dust creation. Siwertell unloaders are very quiet, making them ideal for operations close to populated areas, while their high efficiency makes them market leaders in terms of energy consumption per tonne handled.

Siwertell machines can be installed and operated virtually anywhere, including residential areas, thanks to their totally-enclosed conveyors, light weight and low noise levels (pictured to the left is an unloader in operation in central Frankfurt, Germany)

Siwertell unloaders are designed for layer-by-layer unloading, which minimises dust creation and prevents cargo avalanches inside the hold. Siwertell loaders are equipped with loading chutes that significantly reduce dust creation at loading points. Environmental benefits continue along the conveying line, where negative pressure is created to eliminate emissions and all connection and transfer points are totally enclosed and sealed.

Siwertell also offers unique environmental advantages for specific trades and situations. For example, traditional methods of unloading sulphur are becoming increasingly unacceptable because of pollution and health hazards. Totallyenclosed unloading solves these issues, but sulphur presents a risk of fire and explosion once it is confined.

The terminal unloading operation itself is virtually dust-free�

Jim Gatens, President, Houston Cement Company, US, operating a 1,500t/h Siwertell cement unloader

For Siwertell’s roadmobile unloaders, direct discharge to trucks or wagons is carried out through specially-designed loading bellows fitted with an integrated dust suppression system, resulting in a clean port environment.

To address this problem, Siwertell developed the 4S Siwertell Sulphur Safety System for its screw-type unloaders. 4S detects and extinguishes fires and minimises the risk of explosions; while safely containing them when they do occur.

Import operations for similar powdery commodities, such as alumina, are also under threat because of their unacceptable impact on surroundings. Switching to Siwertell’s totally-enclosed solutions can not only secure their future, but also deliver major cost savings.



Ship unloading

World class ship

unloading Siwertell totally-enclosed screw-type unloaders lead the way in efficiency, performance and environmental protection. Continuous operation delivers excellent through-ship capacity for virtually any dry bulk material. Siwertell’s range of continuous screwtype ship unloaders is designed to handle virtually all dry bulk commodities traded across the world, including alumina, coal, biomass, cement, fertiliser, agribulk, clinker, sulphur and grain. Siwertell unloaders are arranged in three main groups in increasing order of size. The main difference between types is in the supporting steel structure carrying the conveyors on the arm system. All systems are tailor-made to suit the particular requirements of the customer, taking into account factors including the size of ships to be handled, the rated capacity required and the dry bulk commodity or commodities to be unloaded. All types can be fixed or run on rails; the smaller types also have the option of running on rubber tyres.

Market-leading technology

Siwertell ship unloaders employ screwtype technology benefiting from the unique counter-rotating inlet feeder invented in 1972.



The inlet feeder digs into the surface of the bulk material and discharges it in a continuous, layer-by-layer operation that minimises the risk of dust-creating cargo avalanches. Siwertell ship unloaders are designed with totallyenclosed conveying lines, transfer points and discharge arrangements to jetty conveyors. A Siwertell ship unloader is totally-enclosed from the pick-up point in the hold, which is below the cargo surface, to the transfer point at the jetty conveyor, ensuring that there is no cargo spillage and that virtually no dust escapes into the atmosphere.

Excellent through-ship performance

Siwertell unloaders offer a wide range of rated capacities, from 200t/h to very high rates of more than 3,000t/h. However, the true measure of their excellent performance is their throughship capacity; the time it actually takes to completely discharge a vessel. This compares very favourably with alternative systems such as grab cranes.



Ship unloading

The continuous nature of the screw-type unloader means that the rated capacity is maintained throughout the main discharge phase, regardless of the level of cargo in the hold. Thanks to the manoeuvrability of the inlet feeder there is very little material left for the final hold cleaning operations. In contrast, grabs must travel progressively further as the cargo level in the hold falls, reducing their discharge rate. They also leave more material in the hold, increasing the time needed for the final clean up. Siwertell’s sustained high through-ship unloading rate significantly reduces discharge times. In combination with its light weight construction, this results in substantial cost savings.

Sensitive and safe cargo handling

Independent tests and customer experience confirm that Siwertell unloaders and conveyors handle bulk materials very gently, causing little or no cargo degradation. This is particularly important for certain bulk cargoes including alumina and grain. Siwertell has developed specialised systems for the safe handling of dry bulk cargoes such as sulphur and biomass that are subject to risk of combustion and explosion.

Continuous engineering developments

Engineering solutions for dry bulk handling are developed through Siwertell’s exceptional industry knowledge and experience. Siwertell focuses on developing products that meet the constantly changing needs of the market, particularly with regard to function and capacity. One of Siwertell’s most recent developments is its newly launched 3,000t/h coal unloader, which was designed to meet the coal industry’s growing requirements for higher capacities and shorter unloading times.



Dedicated Siwertell coal intakes for steelworks can save millions of dollars Large steel plants traditionally use the same unloading equipment for the iron ore and coal used in the production process. However, differences in the bulk materials’ properties mean that the grab cranes used are a compromise and are not the best solution for either commodity. Separate, dedicated unloading systems for iron ore and coal can deliver a far more efficient operation with major cost savings. Very high capacity Siwertell screw-type unloaders are the ideal equipment for the coal intake. In an industry first, the Ha Tinh steel plant in Vietnam is equipped with two rail-mounted Siwertell ST 940-DOB coal unloaders, each with a rated capacity of 2,400t/h. They are used to discharge vessels of up to 205,000 dwt. Siwertell estimates that reduced discharge times alone will save the owners US$2.4 million per annum. However, it does not stop at that; further savings are made by the reduction in equipment operating time and the associated maintenance requirements, along with the cost of drivers and other personnel. With no spillage there are no clean up costs for the ship and jetty. Grab cranes can lose up to two percent of a vessel’s cargo, while there is no loss using a Siwertell unloader. Over the lifetime of the plant, say 20 years, a Siwertell unloader could be expected to save the operator up to US$160 million.

for unloading in multiple locations

go mobile

Mobile and flexible

Siwertell offers three sizes of offthe-shelf road-mobile unloaders. These versatile machines are the ideal solution for operators looking for flexible, reliable and efficient unloading solutions for smaller vessels and barges. They are particularly suited for ports with little or no bulk handling infrastructure as they can discharge directly into trucks or rail wagons. Mobile unloaders have unloading capacities of up to 500t/h and can handle vessels up to 15,000 dwt. They are available in electric and diesel-driven versions.

Road-mobile systems offer the highest level of flexibility; the unloader is mounted on a roadlegal semi-trailer, allowing it to be used at multiple locations. Once on site, the unloader can be unfolded and made ready for work by just one person in less than an hour. Packing up when discharge is complete is also quick and easy. For mobility within a single port, Siwertell offers gantry-mounted versions. These can be equipped with self-propelled rubber wheels, or steel wheels designed to run on rails. Mobile unloaders can also be installed on static foundation turrets; this provides extra height so that they can handle larger ships of up to 20,000 dwt.

Clean, continuous operations

Mobile unloaders employ Siwertell’s totally-enclosed screw technology. They can transfer cargo to any shore-based conveyors. Siwertell’s mobile pneumatic conveying systems are designed to be the perfect match for its range of mobile unloaders, ensuring extremely clean transfer of cement and other powdery materials from the ship to the storage facility. Cargo transfer directly to trucks or wagons takes place via loading bellows. A double-bellows system allows seamless change-over when a truck or wagon is full, without the need to interrupt the discharge process.

Ship unloading

Designed to meet

grain market demands Port-mobile grain unloader

Siwertell is the world-leading manufacturer of ship unloaders based on screw-conveyor technology. Installations can be found at grain terminals across the globe and range from smaller road-mobile unloaders to massive unloading installations with record-beating capacities, and everything in between. Now, meet the latest addition to the Siwertell grain product family, the port-mobile unloader (PMU).

Delivering a competitive edge

Optimized on many key levels, the standardized unloader offers full port mobility, excellent efficiency and rated capacities and reduced investment costs. From its stable, lightweight steel structure through to its smooth, gentle cargo handling, which delivers extremely low degradation rates, the standardized port-mobile unloader delivers efficient use of jetty space and minimized total operational and maintenance costs. THIS IS IS SIWERTELL SIWERTELL 1212 THIS

It is available as a 400t/h or a 600t/h unit and serves as an ideal solution for operators looking for a portbased system to discharge vessels up to 60,000 dwt.

A great advantage

One of the greatest advantages of unloading grain with screw-conveyor technology is the low degradation rates of the material. A low conveying velocity and a gap between the screw and the casing prevents the kernels becoming crushed during unloading. Siwertell unloaders therefore avoid the cargo degradation concerns that traditionally accompany pneumatic unloaders, while maintaining equivalent throghputs.

Ideal for port operations The new Siwertell port-mobile unloader features a number of advantages designed to optimize its use in ports. For example, the size and dimensions of its steel chassis has been minimized to ensure a lightweight design, which avoids costly additional infrastructure or preparatory quay-reinforcement work. It is fitted with a set of heavy-duty rubber tyres and an advanced steering system, enabling it to easily navigate around sharp curves and obstacles. Operated manually or by using any of the pre-programmed driving modes, when not in use the portmobile unloader can quickly relocate and stow elsewhere, leaving the jetty area clear.

Ship loading

Loading ships

for export

Siwertell’s tailor-made loaders offer market-leading efficiencies and capacities using three conveying technologies: screw-type, belt-type and aeroslide. Outstanding performance extends to loading fragile dry bulk cargoes with minimal degradation. All Siwertell loaders are individually designed to perfectly suit their operational requirements. Siwertell has delivered systems with loading capacities up to 5,000t/h and it can design and deliver higher capacity loaders if required.

Outstanding performance

Siwertell loaders maintain their rated capacity throughout the ship loading process. Outstanding performance is linked not only to loading rates, efficiency and low power consumption, but also to an ability to handle fragile cargoes without degradation.

Siwertell loaders are truly versatile and can handle both compact and free-flowing materials. For example, Siwertell can design a loader that is equally efficient and environmentally friendly when loading cement or clinker – two commodities handled by the same industry, but with totally different characteristics. To excel in dust-free operation, Siwertell loaders are equipped with enclosed conveyors and dust removal facilities at all conveyor transfer points. They are also equipped with loading spouts appropriate to the materials to be handled.

Numerous worldwide references confirm the operational advantages offered by Siwertell ship loaders



Siwertell loaders are delivered as stand-alone units or as part of a terminal system. They are based on screw, aeroslide or belt conveying technologies (page 15). A stationary loader is costeffective in terms of overall investment costs. However, ships need to be manoeuvred during the loading procedure so that all holds can be reached. A rail-travelling loader offers the most efficient loading; if the travelling length is adequate it can reach all of a ship’s holds with no need to move the vessel. To achieve maximum efficiency, a travelling loader should be fed by a jetty conveyor. A slewing loader’s horizontal arm slews over a typical range of ±110° to allow it to reach into all areas of the hold and spread the cargo well. This type of loader is available with all varieties of conveyors.

to another arm which also slews ±110°. This configuration provides even better reach into all parts of the hold. This type of loader is available only on a stationary unit with a screw conveyor configuration.

The ship loader project was successfully completed on time and on budget, despite a short leadtime, which was critical to meeting Arrium’s business objectives” Paul Saliba, Strategic Sourcing Manager, Arrium Mining and Materials, Australia

Slewing loaders can be fitted with a scissor arm conveyor. The horizontal arm slews over a typical range of ±110°. It is connected

The horizontal arm has a linear telescoping mechanism that allows it to position the loading spout at several positions across the width of the hatch opening.

Worldwide references

Numerous worldwide references confirm the operational advantages offered by Siwertell ship loaders. A notable example is the 4,500t/h capacity ship loader delivery for international mining company Arrium. In 2012 the company undertook a major port expansion project with the primary aim of doubling its iron ore export sales. The loader has one shuttle belt conveyor and loads cargo directly into bulk vessels up to 45,000 dwt. Its shuttling motion, combined with the loader’s travelling capability, means it can reach all corners of a vessel’s holds without the need to move the vessel along the berth. It achieves the cleanest possible cargo transport from the shore to the ship’s hold.

Telescoping mechanisms are available for belt-type loaders and can be combined with slewing capability for stationary loaders. THIS IS SIWERTELL 15

Dry bulk terminals

Dry bulk



Siwertell’s range of totallyenclosed conveyors offers the ideal solution for all types of dry bulk cargo. With a number of conveying technologies in its portfolio, Siwertell delivers conveyors for all situations, ranging from dedicated singlecommodity terminals, right through to complex dry bulk cargo hubs requiring a mix of conveying products. 16


Trouble-free dry bulk loading and unloading operations depend on optimum conveying arrangements. The smooth and efficient transport of bulk materials around a terminal demands versatile, reliable, environmentallyfriendly conveying equipment that can be relied on for excellent, long-term performance.

Aeroslide conveyors

Siwertell aeroslides are used to convey dry, powdery bulk commodities such as cement, dry fly ash and alumina. They offer continuous, clean transportation with no limit to the conveying length and take advantage of gravity to transport large amounts of material over long distances at relatively slow speeds. Siwertell aeroslides are constructed in two sections separated by an air-permeable membrane. The dry bulk material occupies the upper section, while the fluidising air supply is introduced via the lower section. Installed with a slight downward inclination, the aerated material flows like a liquid under the effect of gravity.

Economical, clean and kind to cargo Siwertell aeroslides offer a number of advantages for the operator including low investment costs and low energy consumption. With few moving parts, reliability is high and maintenance requirements and costs are low. Aeroslides provide great flexibility, and their totally-enclosed construction ensures extremely clean conveying operations. They also handle their cargo carefully, with little or no degradation.

Combines well with other conveying systems The aeroslide’s requirement for a downward flow of material often fits well with a terminal’s topography. In cases where a continual downward flow is not possible, an aeroslide system can easily be combined with one of Siwertell’s other conveying technologies to provide an effective integrated solution.

Belt conveyors

Siwertell belt conveyors can be used for handling a broad range of commodities including grain, feedstuff, fertilisers, coal, ores and minerals. They are particularly well suited for conveying lumpy, granular and sticky materials. As with all other Siwertell products, excellent environmental credentials are a top priority. Siwertell has worked hard to deliver clean operations closely comparable with its other totally-enclosed technologies. Power consumption is low and reliability is excellent, providing very economical operations.


Dry bulk terminals conveyors

Screw conveyors

Siwertell screw conveyors have a great reputation for efficiency, trouble-free performance and longevity. They are completely enclosed, which provides unrivalled environmental protection. Employed in many applications worldwide, including ports, cargo-hubs, silos, offshore transhipment facilities, shore-based industries and power plants, screw conveyors can handle a wide range of dry bulk materials including coal, cement, lime, raw meal, apatite, urea, fly ash, gypsum, alumina and biomass.

Compact technology Using a combination of vertical, horizontal and inclined units, Siwertell screw conveyors offer compact solutions requiring minimal installation space. Being competitively priced, they do all this for a low capital investment. Siwertell conveyors have a small physical footprint compared with alternative technologies. For example, a vertical screw conveyor takes up much less space than a bucket elevator. This makes them an attractive option when space is at a premium, as is often the case when establishing a bulk terminal in an existing port or expanding an existing facility.



Flexible installation arrangements A screw conveyor can elevate material by up to 40m depending on size and capacity. For greater elevations, Siwertell combines two or more conveyors in series, each one feeding into the next. The same principle applies for extended horizontal and inclined conveying requirements. Similarly, higher capacity conveying can be achieved by arranging two or more conveyors in parallel, served by the same loading box. To date, the highest capacity vertical and horizontal Siwertell screw conveyor installations are rated at 1,500t/h for cement; however even higher capacities can be achieved if required.

Design parameters The design parameters for Siwertell screw conveyors are unique for each application and every solution is engineered according to an operator’s specific needs.

Dry bulk terminal The Siwertell-designed terminal in Klaipéda, Lithuanian, is an extremely efficient, automated, environmentally-friendly multi-mode facility owned and operated by major stevedoring company Bega. Siwertell’s turn-key delivery included two linked warehouses – with a total storage capacity of 160,000m³ – divided into eight compartments, along with a covered loading and unloading station for rail wagons and trucks. A Siwertell ship loader, capable of handling Panamax vessels at 1,200t/h, was installed on a new jetty. Since commissioning, Bega has doubled its cargo handling capacity to five million tonnes per year and now provides the most efficient bulk transfer services in the Baltic region. It can re-distribute bulk material from large bulk carriers, not only by road and rail, but also by smaller vessels covering the Eastern Baltic region.

Ship unloader Siwertell delivered a multi-fuel receiving system to TP Utilities for its Tembusu Multi-Utilities Complex (TMUC) on Jurong Island in Singapore. The large amount of fuel required for the plant means that the island’s jetties are frequently occupied by bulk carriers delivering coal and biomass. The double conveyor system with two unloaders provides TP Utilities with full fuel supply redundancy all the way from the loaded vessels to the storage facilities. Singapore has strict environmental regulations that require industrial operations to minimise fugitive dust emissions. Hardly any dust escapes from Siwertell unloaders, resulting in very clean operations.

Ship loader Siwertell loaders are well-established as a preferred system for alumina loading. Alunorte owns one of the world’s largest alumina production plants in northeast Brazil and contracted Siwertell to replace its existing belt-type ship loader because of problems related to its high dust emissions. Alunorte’s new Siwertell new ship loader is radically different to the system it replaces. It is based on a totally-enclosed aeroslide conveying system with a Cleveland cascade-type vertical telescopic loading spout. Two dust collectors at the transfer points eliminate dust emissions into the atmosphere. The loader is mounted on a rail-travelling gantry and the horizontal arm is capable of slewing and luffing motions. It is used to load vessels of up to 80,000 dwt.
