In coal-fired power plants and aggregate processing facilities, proper classification of conveyor areas is critical for safety and efficiency. The coal conveyor system transports raw materials to crushers, screens, and storage bins in stone crushing/sand making production lines.
Key equipment parameters:
| Equipment | Capacity | Power | Belt Width |
|---|---|---|---|
| Primary Crusher | 200-800t/h | 90-315kW | 650-1400mm |
| Secondary Crusher | 100-500t/h | 75-250kW | 500-1200mm |
| Screening Machine | 50-600t/h | 5.5-30kW | – |
| Belt Conveyor | – | 3-55kW | 500-1600mm |
Q: What’s the typical inclination angle for coal conveyors?
A: Generally ≤18° for standard belts, up to 28° with special cleated belts.
Q: How to prevent material spillage?
A: Use reinforced belt edges, proper skirt boards (150-200mm height), and impact idlers at loading points.
Q: What maintenance intervals are recommended?
A: Weekly inspections for rollers/bearings, monthly belt tension checks, annual motor servicing.
A 500tph limestone crushing plant implemented our conveyor solution featuring:
– Dust-proof design with IP65 enclosures
– Fire-resistant belts (EN14973 certified)
– Emergency stop systems every 20m
Resulted in 23% less downtime compared to previous systems.
Proper zoning (Class II Division 2 for coal areas) and explosion-proof equipment selection ensured compliance with ATEX standards while maintaining production efficiency. The system achieved 98.7% availability during the first year of operation.
