Bulk materials handling
Loading zones and discharge points are common sources of belt damage, spillage and carryback. Correctly selected impact support, belt cleaners and idlers can help reduce these problems. Selection depends on the material, belt condition and transfer arrangement.
Send the belt width, speed, material, loading conditions and existing component details. We can review cleaners, impact beds, idlers, pulleys and selected conveyor equipment as part of the same enquiry.
Product lines
Eight lines covering the loading zone, the carrying and return strands, the drive station and specialist conveyor types.
Primary and secondary belt cleaners for different belt widths, speeds, splice types and conveyed materials. Cleaner selection is confirmed from the application details supplied.
Impact bars support the belt through the loading zone. Bar layout, frame rating and access for replacement must be selected for the conveyor; slide-out or lowering sections depend on the quoted design.
Carrying, return, impact, spiral and training rollers manufactured to the dimensions and duty specified in the enquiry. Bearing, seal and tube options are selected for the operating environment.
Troughing, return, impact and self-aligning idler assemblies can be configured for the belt width, trough angle, load and tracking requirements.
Drive, tail, bend, snub and take-up pulleys with rubber or ceramic lagging. Supply or refurbishment options are reviewed against drawings, dimensions, shaft and bearing details.
Travelling tripper cars and plough dischargers for stockyard and bin filling applications, supplied with rail gear, chutes and control arrangements.
Pipe conveyors enclose the conveyed material to help control dust and spillage and can negotiate routing that may not suit a conventional troughed belt. Final suitability depends on material and route data.
Steep-angle conveying with corrugated sidewalls and cleated belts, for applications where site space will not allow the length a conventional incline would need.
Belt cleaners
Select the cleaner and blade together with the belt splice, speed, material and mounting arrangement. Some tungsten-carbide tips are approved for mechanical fasteners; others are not. Compatibility must be checked for the specific blade and splice.
H-type segmented alloy-blade cleaner. Confirm blade specification, pulley diameter, belt width and splice compatibility before selecting the mounting position.
P-type segmented alloy-blade cleaner. Confirm its intended cleaning position, tensioner and splice compatibility from the supplier drawing; the type name alone does not establish suitability.
GH-type cleaner with a continuous blade. Blade material, mounting position and tensioning arrangement are confirmed for the selected model and conveyor.
Return-strand cleaner for removing material from the inner belt surface before it reaches a pulley. Confirm travel direction, mounting clearance and blade arrangement.
Powered brush cleaning for sticky, wet or fibrous material that a blade cannot release cleanly, such as clay-rich or high-moisture feeds.
Cleaner for a reversible conveyor application. Confirm the approved operating directions, blade geometry and mounting position for the quoted model.
Twin-head cleaner with counterweight tensioning. Required blade pressure, available clearance and guarding are reviewed for the installation.
Combined wet belt-cleaning equipment. Water supply, drainage, slurry handling and suitability for the conveyed material must be checked before selection.
Impact beds & bars
Impact beds support the belt beneath the loading chute. The frame and replaceable bars are selected for the belt geometry, material load and available maintenance space.
Send the details below with a drawing or clear photographs of the loading zone.
| Application details | Used to check |
|---|---|
| Belt width, trough angle & speed | Support geometry and operating conditions |
| Maximum lump size, mass & drop height | Impact duty and frame rating |
| Feed rate & loading-zone length | Bed length and bar arrangement |
| Mounting dimensions & service clearance | Fitment and access for bar replacement |
| Site conditions & required certifications | Material selection and corrosion protection |
Rollers
Selected against the duty at each point on the conveyor — carrying side, loading zone, return strand and cleaning position.
Cylindrical carrying or return roller. Specify shell diameter, face length, shaft ends, bearings, seals, load and belt speed.
Rubber-disc impact roller for the loading zone. Disc arrangement, shaft, bearings and rated duty must match the transfer conditions.
Tapered roller used in a compatible training-idler assembly. Carrying or return position and mounting geometry depend on the selected assembly.
Spiral-profile roller intended to help shed material build-up in suitable return-belt applications. Confirm belt compatibility and rotation requirements.
Flanged friction roller for compatible belt-training assemblies. This is an idler component, not a driven conveyor pulley.
Self-aligning idler sets
Training idlers can help control belt drift, but correct alignment, loading, belt splicing and pulley condition remain essential. The range below includes support sets as well as training sets.
| Set type | Trough angle | Where it is used | How it works |
|---|---|---|---|
| Normal troughing self-aligning | To conveyor drawing | Standard carrying side | Pivoting set that corrects belt drift on the carrying strand |
| Normal flat self-aligning | Flat | Return strand, wide belts | Flat pivoting set for return belt training |
| Normal impact idler set | To conveyor drawing | Under the loading chute | Rubber-disc roller support rated for the loading duty |
| Rubber-disc return set | As specified | Return strand, sticky material | Disc arrangement helps shed build-up; tracking depends on the assembly |
| Tapered self-aligning set | To conveyor drawing | Carrying side, high tonnage | Tapered rollers in a compatible pivoting training assembly |
| Training (friction) set | To conveyor drawing | Carrying side | Friction-driven training set for persistent misalignment |
| Rising self-aligning set | To conveyor drawing | Long overland conveyors | Set rises on the misaligned side, applying a corrective force |
| Hydraulic self-aligning set | To conveyor drawing | Heavy duty, high tonnage | Hydraulic training arrangement selected for the conveyor |
Pulleys
Send the existing pulley drawing or key dimensions so replacement fit, shaft, bearings, lagging and duty can be reviewed before quotation.
| Pulley type | Function | Lagging | Notes |
|---|---|---|---|
| Drive (head) pulley | Transmits torque | Rubber or ceramic lagged | Lagging is selected for traction, belt condition, tension and operating environment |
| Tail pulley | Turns the belt at the tail end | Rubber lagged | Tension control depends on the take-up arrangement; tail pulleys are not inherently tensioning devices |
| Bend and snub pulleys | Changes belt direction or wrap | Plain or lightly lagged | Bend pulleys redirect the belt; a snub pulley increases wrap around a neighbouring pulley |
| Take-up pulley | Maintains belt tension | Plain | Works with the take-up system to hold correct belt tension |
| Refurbished pulley | Any of the above | Re-lagged, re-shafted, rebalanced | Condition assessment is required before refurbishment can be quoted |
Specialist conveyors
Two designs that solve routing and space problems a standard conveyor cannot.

Questions
Nine of the questions we field most often, answered properly.
A primary cleaner removes the bulk of carryback at the head pulley, while a secondary cleaner addresses remaining fines and moisture on the return side. Actual cleaning performance depends on the conveyed material, belt condition, speed, splice and installation. A matched system should be selected from site data.
Some tungsten-carbide blade designs are suitable for mechanical fasteners, while others can damage the splice. Provide the fastener type, belt condition and speed. Use only a blade and tensioner combination approved for that splice; polyurethane is another option where suitable.
Confirm compatibility from the cleaner manufacturer documentation. Blade hardness alone is not a reliable selection rule.
Blade life varies significantly with material abrasiveness, belt condition, cleaner position, tension and maintenance. Inspection intervals should be based on observed wear and the site shutdown plan.
Inspect blade wear, tension and fastener clearance according to the cleaner instructions. Replacement kits and access requirements depend on the selected model.
For a reversible conveyor, select a cleaner explicitly rated for both travel directions. A single-direction cleaner may be damaged or unsafe when the belt reverses.
Provide the belt width, speed, splice, reversal pattern and available mounting space so the correct arrangement can be reviewed.
Impact idlers support the belt on rotating rubber-disc rollers. Impact beds use resilient bars to support the loading zone between and along the contact surfaces.
An appropriate impact bed can reduce belt deflection and improve skirt sealing, but cannot guarantee prevention of punctures or belt damage. Check impact energy, frame rating, belt friction and access.
Provide belt width, trough angle, speed, maximum lump size and mass, drop height, feed rate, loading-zone length and mounting dimensions. The bed and bar arrangement must be selected for the resulting duty.
For severe-duty applications, send the maximum lump size and mass, drop height, belt width and speed so the frame duty, bar profile and bed length can be reviewed.
Some impact-bed designs allow bars to be removed through slide-out or lowering sections. Access depends on the supplied frame and the surrounding conveyor structure; confirm the maintenance procedure before ordering.
Replacement time depends on the bed design, access and isolation procedure. Replacement bar kits can be matched to the confirmed frame profile.
Rubber and ceramic lagging are selected according to pulley duty, belt tension, traction, wetness, abrasion and belt-cover condition.
Ceramic lagging may improve traction in some duties, but is not automatically the right choice. Specify any fire-resistance, antistatic or site requirements and obtain the applicable test evidence before ordering.
Fit must be confirmed from the existing drawing or measured dimensions. Provide shaft diameter, bearing arrangement, shell diameter, face width, lagging specification and operating duty. We will review these details and state the agreed replacement scope on the quotation.
These details allow us to review suitable cleaners, impact beds and idlers and identify any additional information needed for a quotation.
