In coal-fired power plants and mining operations, efficient material handling systems rely heavily on robust conveyors and crushers. These components form the backbone of aggregate production lines, ensuring seamless processing from raw coal to usable sand/gravel.
| Equipment | Model | Capacity (t/h) | Power (kW) |
|---|---|---|---|
| Belt Conveyor | TD75 | 100-2000 | 5.5-315 |
| Jaw Crusher | PE600×900 | 50-160 | 55-75 |
| Impact Crusher | PF1214 | 80-160 | 132-160 |
| Cone Crusher | S240EC | 150-380 | 220-315 |
Raw coal enters through vibrating feeders to primary crushers (typically jaw crushers). Secondary crushing employs impact or cone crushers for finer sizing. Specially designed conveyor belts with fire-resistant rubber transport materials between stages. Final screening separates aggregates into 0-5mm, 5-10mm, and 10-20mm fractions.
Q: How to prevent belt slippage?
A: Ensure proper tensioning systems and use chevron-pattern belts for steep inclines.
Q: Crusher capacity drops suddenly?
A: Check for material bridging or worn crushing chambers/lining plates.
Q: Dust control methods?
A: Install water spray systems at transfer points and use enclosed conveyors.
A Mongolian coal mine implemented a 500tph system combining:
– Primary: PE1200×1500 Jaw Crusher
– Secondary: Two HST315 Cone Crushers
– Tertiary: VSI1145 Sand Maker
The plant achieved 95% availability with dust suppression systems reducing
