3. Conveyor Belt Scrapers and Cleaners
Conveyor belt scrapers remove carryback material from the belt to help reduce spillage, material accumulation and unnecessary cleaning requirements.
Available types and configurations:
- Primary belt scrapers
- Secondary belt cleaners
- Polyurethane scraper blades
- Tungsten-carbide-tipped scrapers
- V-plough belt cleaners
- Return-belt cleaning systems
4. Conveyor Impact Beds
Impact beds support conveyor belts beneath loading and transfer points where falling material creates concentrated impact forces. Correctly selected systems help protect the belt and supporting structure.
Available types and configurations:
- Standard impact beds
- Heavy-duty impact beds
- Adjustable impact beds
- Low-profile impact beds
- Replaceable impact-bar assemblies
5. Conveyor Belt Fasteners
Mechanical conveyor belt fasteners join compatible belt ends where a mechanical splice is appropriate for the belt construction and operating conditions.
Available types and configurations:
- Hinged belt fasteners
- Solid-plate fasteners
- Rivet-hinged fasteners
- Mechanical belt lacing
- Belt fastening installation tools
6. Conveyor Belt Tracking Switches
Tracking switches detect excessive conveyor belt movement away from its intended path. Depending on the model and control system, they can activate alarms or initiate protective shutdowns.
Available types and configurations:
- Single-stage belt sway switches
- Two-stage belt misalignment switches
- Roller-arm tracking switches
- Heavy-duty industrial limit switches
7. Conveyor Speed Sensors and Zero-Speed Switches
Speed sensors monitor conveyor belt or rotating-shaft movement. Zero-speed and underspeed switches detect when movement falls below a configured threshold, supporting conveyor monitoring and protective control functions.
Available types and configurations:
- Conveyor speed sensors
- Zero-speed switches
- Underspeed monitors
- Inductive proximity sensors
- Rotary encoders
- Non-contact belt speed sensors

Tips for Buying Conveyor and Bulk-Material Handling Components
1. Confirm the Exact Part Number
Provide the manufacturer’s name, part number, equipment identification and clear photographs of the existing component. Include drawings or datasheets where available.
2. Verify Dimensions
For rollers and idlers, confirm diameter, face length, shaft dimensions, shaft-end arrangement and bearing type. For pulleys, provide diameter, face width, shaft details and lagging requirements.
3. Consider the Conveyed Material
Coal, iron ore, aggregates, fertiliser and grain have different abrasion, moisture, impact and contamination characteristics. Select materials and components suitable for the operating environment.
4. Match Components to the Conveyor Belt
When selecting scrapers, fasteners and impact beds, check belt width, thickness, speed, tensile rating, pulley diameter and loading conditions.
5. Check Electrical Specifications
For tracking switches and speed sensors, verify supply voltage, output type, switching arrangement, sensing distance, enclosure protection and temperature range. Confirm site-specific safety and hazardous-area requirements where applicable.
6. Verify OEM and Aftermarket Compatibility
An aftermarket part must meet the necessary dimensions, performance requirements, material specifications and operating limits. Physical fit alone does not establish equivalence.
7. Compare Total Cost
Consider purchase price, freight, delivery lead time, installation, expected service life and the potential cost of downtime when comparing alternatives.
8. Plan for Critical Spare Parts
Identify components with long lead times or significant consequences if they fail. Establish appropriate minimum stock levels based on operating history and procurement requirements.
