In coal mines, metal mines, and cement plants, conveyor belts are the backbone of material handling systems. They transport massive volumes of raw materials efficiently over long distances, reducing manual labor and operational costs. However, choosing the right conveyor belt and applying proper maintenance can make the difference between smooth operations and costly downtime.
This guide provides practical, industry-tested advice for product managers and procurement teams to select the best conveyor belts for their applications and maintain them for maximum service life.
1. Understanding Conveyor Belt Types for Mining and Cement Industries
1.1 Coal Mine Conveyor Belts
Key Requirements: Flame resistance, anti-static properties, abrasion resistance.
Common Types:
- Flame Resistant Conveyor Belt – Essential for underground mines to meet safety regulations. Example: A coal mine in Shanxi extended belt lifespan by 20% after switching to a flame-resistant model.
- Abrasion-Resistant Rubber Belt – Designed to handle sharp coal particles.
- Heat-Resistant Belt – For hot materials near crushers or transfer points.
1.2 Metal Mine Conveyor Belts
Key Requirements: High tensile strength, impact resistance, corrosion resistance.
Common Types:
- Steel Cord Conveyor Belt – Best for long-distance, heavy-load applications. Example: A copper mine improved conveying efficiency by 15% after upgrading to steel cord belts.
- Chevron Belt – For inclined conveying of ore and crushed stone.
- Impact-Resistant Belt – For areas under loading points with large lumps.
1.3 Cement Plant Conveyor Belts
Key Requirements: Heat resistance, chemical resistance, abrasion resistance.
Common Types:
- Heat-Resistant Belt – Withstands clinker temperatures up to 200°C.
- Oil-Resistant Belt – For handling oily raw materials or additives.
- Corrugated Sidewall Belt – For vertical or steep-angle conveying.
2. Key Factors to Consider in Conveyor Belt Selection
1. Material Type & Size – Sharp or abrasive materials require higher abrasion resistance.
2. Operating Environment – Underground coal mines require flame-resistant belts; cement plants need heat resistance.
3. Conveying Distance & Load – Steel cord belts are ideal for long hauls with heavy loads.
4. Belt Speed & Incline Angle – Higher speeds increase wear; steep inclines may require cleated or chevron belts.
5. Regulatory Compliance – Always meet local and international mining safety standards.
3. Conveyor Belt Maintenance Essentials
3.1 Routine Inspections – Check for belt misalignment, wear patterns, and splice integrity. Inspect pulleys, rollers, and idlers.
3.2 Proper Tensioning – Over-tensioning causes stretch; under-tensioning causes slippage.
3.3 Belt Cleaning – Use primary and secondary belt cleaners to prevent carryback.
3.4 Splice Maintenance – Hot vulcanized splices last longer than mechanical fasteners.
4. Common Conveyor Belt Problems & Troubleshooting
| Problem | Possible Cause | Solution |
| Belt Misalignment | Uneven loading, misaligned pulleys | Adjust loading chute, align pulleys |
| Excessive Wear | Wrong belt type, abrasive materials | Select higher abrasion-resistant belt |
| Slippage | Low tension, worn drive pulley lagging | Adjust tension, replace lagging |
| Splice Failure | Poor splicing method, overloading | Use quality vulcanization, reduce load |
| Material Carryback | Inadequate belt cleaning | Install belt cleaners, improve chute design |
5. Best Practices to Extend Conveyor Belt Lifespan
- Select the Right Belt from the Start – Saves repair costs later.
- Use Impact Beds & Skirt Rubber – Protects the belt at loading points.
- Install Proper Belt Cleaners – Reduces carryback and wear.
- Schedule Preventive Maintenance – Avoid unplanned shutdowns.
- Train Maintenance Teams – Skilled technicians extend belt life significantly.
