Critical Roller FeaturesHi–Quality Balanced TubeSTEEL: HD NYLON: ALUMINIUM

It is critical that the Total Indicator Run Out (TIR) is kept to a minimum. Excessive TIR and MIS (Mean Indicator Slope)causes belt flap, vibrations and reduces bearing life. It is even more critical when producing low noise rollers, which are becoming increasingly important in today’s environment.

Greater Bearing LifeThere are a number of principles that need to be followed to achieve increased bearing life. To achieve the best possible service life, shaft selection is critical and must be designed to reflect the correct running capability of the conveyor and incorporate the below:

• Carried material

• Flooded belt loading

• Belt mass

This helps minimize angular misalignment in the bearing caused by shaft deflection.

As the shaft is only supported at each end, it must also accept the load from the shell to the bearings at each end. It is critical to minimize the angular deflection at the bearings. Bearings must have a L10 basic rating life of 65,000 hours (or as specified by the client) for bearing loads encountered at the operating design duty, calculated in accordance with AS2729.

Shaft Detail The shafts consist of cold drawn mild steel-polished round bars in accordance with JIS-G3123 SGD 3 and other equivalent standards. Black shafts -JIS-G 3101-SS400 equivalent to ASNZS3679 are machined for “step-down” for respective bearing fitting. Particular attention is given to the bearing seat machining and seal location.

End HousingsThe end discs are fabricated from ASNZS1594, JIS-G-3131 - pickled and oiled-coils. The fabrication of the end housing consists of a multi-stage precision automatic pressing operation, which provides such a high degree of accuracy for bearing and seal location, that no further machining is necessary. The end housings are chemically degreased after manufacture.

Roller Seal PackagesOne of the most important aspects to the service life of a roller, is the sealing arrangement.

RS Premium Seal PackageStarting from the external side, the various protective elements are:

• Protective anti-corrosive shield located firmly on the shaft, which acts as a barrier against the entry of foreign particles

• Low friction rubber lip seal to prevent the entry of liquid

• Steel cover cap with a large chamber where any dust particle that might enter is trapped

• Triple labyrinth male preloaded with grease seal is installed

• Triple labyrinth female preloaded with grease seal covers the male labyrinth to form the last barrier of defence before the bearing

• Rear seal is fitted to protect the bearing from mill scaling and any inherent contaminant.

Idler Roller BearingsHigh quality bearings are essential to the life of a roller. RKM use a range of quality bearings, SKF, NTN, NSK and the RKM bearings. Rollers are fitted with single row deep groove ZZ type ball bearings with a C3 internal clearance unless otherwise specified. The bearings are factory greased for life with a suitable Lithium based grease with a NLGI consistency of 2 for bearings ≤6206 and consistency of 3 for bearings ≥6306, this offers minimum roller drag and gives maximum resistance to water wash out.

Housing Tube Weld DetailThe idler shells and end housings are 3mm CF fully fillet welded in a special double-ended automatic circumferential welding machine, which gives a minimum of 70% weld penetration and ensures that the shell tubing is concentric at the ends during the welding process, thereby ensuring minimum run-out for the roller as per the BS EN 288 Part 3 ~Acceptance Criteria: ISO 5817:1992 Quality Level or AS/NZS 1554 Part 1-Category-GPand SP.

BAM PRODUCT RANGEBAM have the ability to provide a comprehensive product range that provides our clients with suitable rollers for any application. We use our computerized idler design program, to help select the best possible roller to suit the client’s budget and service life expectancy.

Plain Steel Rollers

Steel Roller TubeThe tube is rolled from electric-resistance-weld ERW 200 -350 range tube, using prime quality steel as per AS1450, BS 1387:1985; GB/T 13792-92 and other equivalent standards for conveyor tubing. Each shell end is precision machined to fit the end housing to ensure concentricity.

Steel Roller Surface TreatmentRollers are firstly put through a de-scaling machine that removes any rust or scale build up before they are solvent cleaned, prior to being coated in an anti-rust inhibitor. The roller ends are then sprayed in enamel paint with a specific color code that identifies the type. Shells and ends can be hot dipped galvanized, or coated with corrosion protective painting systems on request.

Impact Rollers

BAM provides a variety of impact rollers including:

• High impact bull nose poly rollers

• Rubber disc impact rollers

• Mines Department approved FRAS rubber impact rollers

Rubber or poly impacts are a highly effective way to dampen the impact load and hence improve the life span of the rollers used in the impact zone. The rollers are fitted with single row deep groove ball bearings, but in extreme conditions spherical roller bearings are used, which have a greater tolerance to shaft deflection and a higher dynamic capacity. Our impact rollers also use a variety of reinforced bearing housings to adapt to the various drop heights and lump sizes seen in the impact zone.

Rubber disc impacts use press fitted rubber disc’s and a welded retaining ring at each end of the roller is used to ensure the rubber discs are firmly clamped and retained in position during operation.

Heavy Duty Rubber and Poly Impact RollersHeavy Duty Impact Rollers are typically used in heavy-duty mining applications such as impact zones on over burden conveyors.

Typical Heavy Duty Impact Roller

They can be used as a complete multiple roller Impact Idler Set, or commonly used in a 5 roll set in the center locations to absorb high impact loads, with two steel rollers in the wing location under the skirting area.

The Impact Roller has as an added feature where the heavy-duty polyurethane “Bull Nose” discs are keyed to the shell tube to prevent “walking off”.

Where extra high Dynamic Rating Bearings are needed, with a greater tolerance to shaft deflections, spherical roller bearings with common physical dimensions to the Single Row Deep Groove type, are used as shown in the illustrations. The bearings are factory greased for life with Shell Alvania HDX2 or approved equivalent by the bearing manufacturer. This offers maximum protection to impact forces and resistance to water wash out.

Steel Composite & Low Noise Steel Composite Rollers

The BAM steel composite roller utilizes our proven high quality ERW Steel tube with minimal TIR and our specially formulated solid polyester bearing housing. The dynamically balanced tube to AS3709 G16 combined with the precision-machined solid housing offers the quietest running roller on the market today.

Our unique manufacturing process along with our computerized dynamic balancing machine enables us to achieve the best possible TIR and MIS, which reduces any noise generated from the belt running across the surface of the roller. The solid

polyester housing absorbs any vibration within the bearing

housing and deadens any internal noise generated from the roller shell and bearing rotation.

Our housings are designed to withstand large loads, with special care taken to make sure the bearing is located in the most effective position within the housing so that any load is distributed evenly through the housing onto the bearing and shaft.

We have designed into the housing our proven RS seal package along with a primary heavy duty nylon protective outer dual labyrinth shield, which will eliminate any rock jamming & provides additional protection against the ingress of contaminants.

Aluminium rollers are commonly used in the coal industry, as they are light weight and low noise. They are available in the RS model, with either the heavy duty nylon composite housing, or the standard composite housing.

Alloy Shell – Poly Bearing Housings – Roller Features

• Shells are made from a high grade light weight, specially formulated Aluminium alloy.

• End Housings are an interference fit into the tube ends and solid in construction. Material: Specially formulated polyurethane.

• Weight of the Aluminium roller is OH&S friendly, due to light mass. Hollow shafts are used where necessary, to keep the mass down to the client’s specification.

• TIR (Total Indicator Run out) and MIS (Mean Indicator Slope) compliant.

• Balance Quality G16 or 0.05 Nm to ISO3709.

• Roller Material Build Up has good properties against build up.

• Low Noise, which meets customer’s specifications.

Aluminium Rollers

HD Nylon Plastic Rollers

BAM have a range of plastic rollers, suitable for different applications, both in medium and heavy duty.

Our unique manufacturing process, also allows us to meet minimal TIR requirements and be able to dynamically balance the roller to the G number required.

Our purpose built design program, enables us to evaluate the stress and deflection of a plastic roller shell under specific loading conditions. Once the calculations are complete, we can then provide the customer with a detailed, one page print out, including graphs, showing the allowable and actual loads and stresses that are being applied to the roller. From there, we are able to offer the correct plastic roller suitable for the application, using the correct shell thickness along with the correct seal and housing package to suit the client’s budget and service life expectancy.

HD Nylon Plastic Roller Features and Benefits• Roller Shells – are made from a high-grade Nylon. It is a

thermoplastic with the highest Yield Strength and Flexural Elastic Modulus of 2800 MPa, compared with all other plastics. This gives it the unique properties of excellent impact strength, wear and abrasion resistance.

The latest robotic welding technology is used as part of our commitment to ensuring a first-class weld is performed time after time. We conform to all international welding code specifications AS 1554 GP and AS 1554-SP.

Demmeler tables are used to assure our manufacturing tolerances are kept to the required standards, and that each jig is millimetre perfect. Our procedure also takes into account, the stress relieving process caused by the heat

FRAMES, BRACKETS & MINE STRUCTUREgenerated through the welding process, along with the stress caused by the hot dip galvanizing.

Steel is made to ASNZS3679 or equivalent Asian standard. Jig welding of the base frames ensures slotted mounting brackets are accurately aligned. All frames and brackets are hot dip galvanized to AS NZS-4680, which gives affective resistance to a wide range of surface and underground environments.

Frames & Brackets – General Specifications• Frames and brackets are jig welded to idler bases to

ensure the roller and troughing profile is maintained to within 2.0mm deviation.

• Frames and brackets are designed and manufactured to prevent distortion under torsional loads, resulting from both wing rollers being jammed.

• Impact idler bases of the heavy-duty retractable type, can be provided.

• Base frames are designed to self-shed material spilt from the belt.

• Wind guard mounting holes are provided in idler wing brackets.

• Trip wire pigtails share the wind guard holes.

• Idler brackets are designed to allow fitting of retaining plates, clips and stone guards.

• Frames and brackets are provided with elongated fixing holes to suit minimum fixing bolt size M12.

• The clearance between idler rolls and frames are made sufficient to ensure that, should the rolling elements collapse within the roll bearings, a clearance is maintained between the idler rolls and frames.

• Brackets are slotted to accommodate drop-in dead shaft type rollers.

• Bracket slots are neat fitting to prevent rattling components during operation.

• In-line idlers have minimum end gaps between rollers to alleviate belt pinching.

• Trough idler frames for belts wider than 900mm are fitted with a diagonal brace between the outer support and the cross member.

Frames & Brackets – Surface Treatment• Frames and brackets are grit blasted to class 2 ½ and hot dip galvanized,

to AS NZS-4680 or equivalent Asian standard, for greater corrosion resistance and durability in a wide range of surface and underground environments. Thickness is 450-600g/m². Mechanical cleaning followed by enamel paint is available on request.

• Special epoxy painting to suit corrosive environments where galvanizing is not suitable, such as gold mines and salt water is also available.

IDLER CONFIGURATIONSBelow is a guide to various idler configurations and their uses.

Three Roll Trough 20 – 45 degrees range, most commonly used configuration for Carry Idler Sets, Three Roll Weigh Idlers 20 – 45 degrees range

Three Roll Trough Impact 20 – 45 degrees Range

Three Roll Suspended (Catenary) Trough and Impact idlers – 20 – 45 degrees Range

Offset used to assist belt tracking for mainly light and medium duty, up to 1200mm belt. Inline used mainly for medium to heavy duty and belt widths above 1200mm.

Used on weigh machines or load cells, lead in and lead out sets (which have machined and balanced rollers to ensure zero vibration) and jacking screws or cams to ensure consistent sectional profile and alignment so calibration is not affected.

Installed at the loading point to absorb the shocks and to help protect against belt damage. Retractable sets are also used in the skirt area, allowing the rollers to be changed out without disturbing the skirting.

Due to the swing nature this absorbs high impact and less dynamic loads on the rollers. Used in demountable mine structures such as gate conveyors as it is easy to change out and re install.

Three Roll Adjustable transition idlers, usually in increments to a maximum range of 15 degrees

Three Roll Trough Picking idlers, usually 20 degrees

Single Roll Flat carrying plain idlers

Single or Vee Roll Rubber disc return idlers, usually 10 – 20 degrees

Trough Training Idlers, anti-friction or poly pad swivel top frame, activated by servo rollers

Used at head and tail position to support the belt as it goes from the trough to the flat position.

Has a long center roller and short wing roller, used in waste recycling plants to manually separate materials and also belt feeder applications.

Not used very much due to no protection against spillage that trough sets give. Also used in the skirt area outbye of bin and feeder loading area.

Used in wet, sticky or abrasive conditions. Helps belt tracking due to less build up.

Used to train the belt approaching the head end of the conveyor.

Return Training idlers, anti-friction or poly pad swivel top frame, activated by servo rollers

Trough and return side guides

Single Roll Flat Impact Carry idlers

Inverted Vee Training idler

Used to train the belt approaching the tail end of the conveyor.

Prevents the belt hitting and wearing out the structure. Can be used for tracking but it is not advised due to belt damage.

sed in the skirt area under bins and feeders loading area.

Used to train the belt, mainly approaching the tail end of the conveyor. Two trough rollers are usually used with keeper plates to stop the rollers falling out.

Special Trough and Return Side guide roller various belt widths

Drop Down Idler Sets

Used extensively on overland conveyors with horizontal curves, to prevent the belt transversely riding up over the trough and/ or return idler sets.

Extra Heavy Duty in skirted areas, with adjustable legs which allows the rollers to be lowered under the belt for easy removal and replacement.

Three Roll Rigid Suspended Plain or Impact

Spiral Rollers

Basic requirementsThe basic requirements for efficient and safe operation of the belt conveyor idlers along with the associated equipment, inspection procedures etc. are briefly explained below.

The following warning signed are to be strictly adhered to at all times.

DANGER

Serious injury or death of personnel may occur if warning is not observed

WARNING

Serious injury or risk of life to personnel may occur if warning is not observed

CAUTION

Damage to equipment, serious injury or death of personnel may occur if warning is not observed

WARNING

Nylon slings or fibre ropes must be used. Wire rope strictly prohibited

CAUTION

Rubber lagged roller surfaces are prone to damage when subjected to any impact

Safety standards – operationsThe following actions must be strictly observed so as to maintain the operational standards:

• Never step on the idlers.

• Do not touch the idlers when they are in motion.

• At those places where there may be easy access to the idlers, a safety fence should be erected.

• A suitable place/area should be installed for the inspection and repairs in the event of the

• idlers malfunctioning.

• A routine checking of the various aspects of the installations at frequent intervals should be carried out.

HandlingThe loading and unloading of the idlers should always be performed slowly, safely, and preventing any impact to them. A handling machine (forklift, crane, hoist etc.) could be used for the above purposes.

The following signs should be carefully observed.

StorageWhen stacking, the idlers must be stacked horizontally in a dry place. Wooden pallets can be used for stacking. Do not pile up the idlers. Extreme care must be taken of the rubber lagged rollers

For long duration storage, the idlers should be stored indoors. In the event of unavoidable conditions where the idlers have to be stored outdoors, they must be covered to ensure that the idlers are not exposed to dust, moisture etc.
