Be sure to observe the separate operating manual for the chain tensioner used.

Chapter 5: Operation

DANGER

INCORRECT OPERATION ENDANGERS YOURSELF AND OTHERS! INCORRECT OPERATION OF THE MACHINE IS OFTEN THE CAUSE OF VERY SERIOUS ACCIDENTS! OPERATE THE CONVEYOR ONLY WHEN YOU HAVE BEEN SUFFICIENTLY TRAINED ON THE INSTALLED CONTROL UNIT AND HAVE READ AND UNDERSTOOD ALL THE OPERATING MANUALS ON THE CONVEYOR SYSTEM. SHOULD ANYTHING BE UNCLEAR, PLEASE CONTACT YOUR SUPERIOR.

REPORT DAMAGE, DEFECTIVE COMPONENTS OR OTHER FAULTS TO THE RESPONSIBLE SUPERIOR IMMEDIATELY! CHECK ON WEAR OF THE CHAIN SPROCKETS AT LEAST EVERY CAUTION FOUR WEEKS! TURN THE CHAIN SPROCKET AS SOON AS THE SIZE OF THE MARKS INDICATING THE RATE OF WEAR HAS BEEN REDUCED BY HALF (APPROX. 4 MM). PLEASE NOTE THAT THE LIFE OF THE TURNED CHAIN SPROCKET MAY BE MUCH SHORTER THAN THE ”INITIAL PERIOD OF USE” OF THE CHAIN SPROCKET. THIS IS DUE TO TOLERANCES IN THE HARDNESS PENETRATION DEPT. THEREFORE CHECK ON THE WEAR OF THE TURNED SPROCKET AT LEAST EVERY 2 WEEKS.

Should the stripper work loose during operation, the chain sprocket or the drive frame could be damaged. Be sure to tighten the M24-8.8 fastening bolts to the specified torque during installation! The required torque is 655 Nm.

________________________________________ Storage and transport This chapter contains important information on the correct storage and transport of the AFC. Observance of the instructions and tips will increase the service life and availability of the AFC. You will also be able to carry out the transport work quicker and more safely. Careful attention to the points in this chapter will help you to simplify your day-to -day work.

Storage of the equipment corrosion protection

Components coated with temporary corrosion inhibitor are protected for around six months.

no direct exposure to sunlight

Protect the equipment against direct exposure to sunlight. Store the electrical equipment, electronic components, spare parts of rubber or plastic - such as seals and hoses - and hydraulic fluids only in closed rooms at temperatures of 15 C to 25 C.

moisture and dirt

Protect all parts of the equipment stored outdoors against moisture and dirt, e.g. using tarpaulins.

© BUCYRUS 2011

The mounting surfaces of hydraulic components must be protected against corrosion and sealed with blind plates. Protect the hydraulic plug connectors and the connectors of the electrical cables with the caps and plugs supplied. short-term storage

During short-term storage (approx. 4 weeks) of equipment outdoors, but at temperatures above freezing, electrical components need not be removed. Such components must be particularly protected against excessive temperatures, dirt and moisture.

long-term storage

During long-term storage (more than 4 weeks), the equipment must not be stored outdoors. It must be stored in a dry, well ventilated room.

After a storage period of approx. two years, a random sample inspection must be performed to determine whether the measures taken and the method of storage have prevented damage. On request, the inspection can be carried out by BUCYRUS.

natural aging

Even with proper storage, seals and hoses are subject to natural ageing. A storage period of approx. two years is therefore quoted as an indicative value for these parts.

TAKE CARE TO ENSURE THAT NEW SUPPLIES ARE STORED SEPARATELY FROM EXISTING STOCK AND THAT IMPORTANT REMOVAL TAKES PLACE ON THE ”FIRST IN, FIRST OUT” PRINCIPLE.

Transport Load units; dimensions and weights Observe the transport sheets for the various transport units.

They contain information on:  Dimensions  Weight  Lifting points  Centre of gravity, etc.

Where technically possible, the load units have suitable lifting points for transport and assembly.

USE ONLY LOAD HANDLING DEVICES COMPLYING WITH THE TECHNICAL AND LEGAL REGULATIONS FOR THE TRANSPORT OF LOADS. YOU COULD BE SERIOUSLY WARNING INJURED OR EVEN KILLED BY FALLING LOADS. USE ONLY SUITABLE LOAD HANDLING DEVICES.

Before transport C is only permissible when certain measures were taken to meet these conditions at the design and manufacturing stages.

Nevertheless, the individual parts and devices of this equipment must not be subjected to sudden impact loads at such low temperatures and are only loaded statically or quasi-statically.

During transport of this equipment with floor-mounted vehicles at such low temperatures, measures must also be taken to ensure that the parts and devices are not subjected to sudden impact loads. At very low temperatures and on poor roads, the transport vehicle speed must therefore be limited to max. 25 kph for truck transport. electrical and electronic components

Electrical and electronic components must be removed for overseas transport or prolonged storage outdoors unless these components or the complete equipment is protected against harmful environmental influences by a suitable packaging. The electrical cables remain in the equipment. They must be carefully protected against transport damage and soiling of the connections.

Transport of the components machine parts

Drive frame, gearboxes, motors, etc. are equipped with lifting eyes or lifting points for transport.

In some cases you have to screw the lifting eyes into the bores provided before transport and to remove them again immediately after transport.

__________________________________________________ Installation intended use

The AFC transfers the coal to the gate conveyor belt, via the BSL and crusher. The capacity of the AFC is rated at 4,000 tons per hour, however this is dependent on the crusher setting which can vary from 3,000 tons per hour.

IT IS IMPORTANT TO SET THE CRUSHER HEIGHT TO MATCH THE AFC CAPACITY OR STALLING MAY OCCUR ON THE AFC IMPORTANT DUE TO EXCESSIVE LOAD. The BSL has 1542mm pans and runs at a higher speed to ensure the product is removed from the face faster than the face production rate, to reduce the likelihood of blockages. The AFC runs at 465 FPM, approximately 30% faster than the AFC. The BSL as a unit, is advanced by the hydraulic rams in the shields on the face, advancing over the BSL on an overlap system. The overlap allows approximately four (4) pushes of the AFC before the BSL must be advanced.

The BSL is fully enclosed from outbye the crusher to the delivery end, with dust suppression sprays installed along the BSL, in the crusher and at the delivery to minimize dust exposure.

If too much slack develops climbing and jumping of the chains on the chain sprockets will increase.

excessive chain pretension

Excessive tensioning of chains results in power losses as the chains pass around the sprockets. This could lead to excessive wear of chains and sprockets, as well as extreme noise.

changes in chain pretension during operation

As the face advances, the conveyor chain pretension can change as the conveyor takes on different angles in both horizontal and vertical directions.

monitoring the chain assembly

In order to ensure trouble-free operation with favorable drive powers and long service lives of chains and sprockets, the chains must therefore be constantly monitored with respect to the criteria slack chain and noise level. This can give an early indication of when a chain assembly has to be lengthened or shortened.

how to tension the chain assembly

The following auxiliary facilities are required for tensioning the chain assembly:  Chain locking device  Hydraulic or pneumatic chain tensioner

APPLYING THE REQUIRED PRETENSION TO THE CHAIN ASSEMBLY VIA LIFTING TACKLES OR THROTTLED DRIVES IS VERY INACCURATE AND THEREFORE NOT IMPORTANT RECOMMENDED! A CHAIN ASSEMBLY WITHOUT OPTIMUM PRETENSION INCREASES WEAR AND REDUCES THE LIFE OF THE INSTALLATION. THE USE OF A CHAIN TENSIONER ALLOWS YOU TO APPLY THE OPTIMUM PRETENSION TO THE CHAIN. fitting the chain locking device

Place the Chain Locking Device onto the face-end gradient / special pans by inserting the pins of the Chain Locking Device into the slots of the pan deck plate.

________________________________________________________________ 4.34 VUSS / 00 ________________________ BUCYRUS – AFC ©

© BUCYRUS 2011

Changes can also be caused by compression or stretching of the pan line and by changes in the face angle. In addition, changes in load are possible due to fluctuations in the properties of the material conveyed, e.g. changes in moisture content or in the debris content. Finally the conveyor chain assembly itself changes due to increasing permanent elongation.

NOTICE

USE ONLY HYDRAULIC FLUIDS FOR WHICH A VALID CERTIFICATE ISSUED BY BUCYRUS GMBH HAS BEEN MADE AVAILABLE TO YOU. OTHERWISE, THERE IS THE DANGER OF SERIOUS DAMAGE TO THE HYDRAULIC EQUIPMENT AND THE LOSS OF WARRANTY CLAIMS. For the operation of hydraulic components of BUCYRUS GmbH generally only such hydraulic fluids are allowed to be used for which a valid certificate in accordance with EWM 8350 or an exemption permit of BUCYRUS GmbH is available to the respective operator. BUCYRUS GmbH will not accept any claims under warranty for components which have been or are operated with a different hydraulic fluid.

© BUCYRUS 2011

In addition, national - and sometimes also regional - regulations on health and safety at work and any environmental regulations must be observed for operation.

If a mine only uses individual hydraulic components without applying BUCYRUS shield supports or if obtaining a valid certificate would require too much effort, the same hydraulic fluid as is used for the existing shield support shall be allowed to be used for these individual components, subject to approval by BUCYRUS. The same applies e.g. to hydraulic chain tensioners, hydraulically tensionable drive units etc. The respective exemption permit will be issued by BUCYRUS GmbH upon request.

Suitability test Before the certificate of BUCYRUS GmbH is issued for a hydraulic fluid the respective fluid has to be subjected to a suitability test. However, this suitability test only refers to the technological properties of the hydraulic fluid and does not allow any conclusions to be drawn with respect to its properties regarding health and safety and environmental protection.

Original samples of the concentrate and the water which will be used later when preparing the hydraulic fluid at the mine are required to perform the suitability test.

______________________________________________________________ BUCYRUS – AFC © VUSS / 00 6.7

EM026827-0 (EN-US)

Technical data________________________________________________ The suitability test will be carried out by an independent testing institute authorized by BUCYRUS GmbH. For the tests, the criteria as specified in EWN 8350 will be applied. The suitability test mainly serves to clarify the properties of the hydraulic fluid with respect to  stability  sealing materials  corrosion In addition, a chemical ”fingerprint” of the concentrate will be prepared in order to exclude or prove any possible changes in the composition of the concentrate, if required.

© BUCYRUS 2011

If the suitability test shows that the hydraulic fluid meets the requirements, the operator will receive the respective certificate

by BUCYRUS GmbH.

Certificate The customer will be given a certificate attesting the suitability of the hydraulic fluid for the operation of hydraulic systems of BUCYRUS GmbH for each product tested. The respective certificate shall be valid for a period of one year and, after a simplified test, can be extended for an additional year each. The certificate shall become invalid if one or several of the prerequisites for obtaining the certificate are no longer fulfilled.

This is the case, for example, if the quality of the water has changed substantially and/or the composition of the concentrate has been changed, a different concentrate is used or the concentrate and water mixture ratio does not correspond to the data given on the certificate. For further information, please refer to EWN 8350, part 1.

Technical data________________________________________________ Hydraulic fluid maintenance A consistent good quality of the hydraulic fluid is essential for the operational reliability of hydraulic systems. Therefore, maintenance of the hydraulic fluid must not be neglected but should be performed with special care. The most important properties of the hydraulic fluid should ideally be monitored automatically and recorded in order to be able to directly counter any harmful effects. These properties include: temperature, foaming, pH-value, concentrate ratio, and microbial load.

The operator of the equipment has to prepare a hydraulic fluid maintenance concept for any individual application. The maintenance concept should be prepared in close cooperation with the manufacturer of the concentrate and has to be applied consistently.

 pH-value – Target value: 7.5 to 9.5  Concentrate ratio – Target value: see certificate  Microbial load – Target value: < 105 Kol/m In addition, the electrical conductivity, foaming and the operating temperature of the hydraulic fluid should be monitored regularly.

The permissible max. temperature of the hydraulic fluid is 55 °C. During normal operation, however, an operating temperature of 45 °C should not be exceeded. A higher operating temperature will reduce the stability of the emulsion and shorten the life of the sealing material.

Quality of the process water The quality of the water used for the preparation of the hydraulic fluid has an enormous influence on the properties of the hydraulic fluid. Accordingly, the requirements for monitoring the water quality are very high.

The following table lists limit values for the essential properties and components of the water.

If the limit values shown are maintained it can be assumed that the water is basically suitable.

________________________________________________________________ 6.10 VUSS / 00 ________________________ BUCYRUS – AFC ©

© BUCYRUS 2011

If it is not possible to monitor the hydraulic fluid continuously the properties listed in the following should be checked at least once every week:

EM026827-0 (EN-US)

_______________________________________________ Technical data If one or several of the limit values mentioned are not met this should be taken into consideration when selecting a concentrate.

Additional water treatment may also be required.

The customer shall in any case, however, provide a sample of the original water to permit performing the tests required for the issue of the certificate.

© BUCYRUS 2011

Changes in the composition of the water will also lead to the loss of the certificate even if they are within the limit values mentioned.
