Coal crushers play a critical role in aggregate processing lines, especially when coal-fired power plants integrate with sand/gravel production. The Bureau of Indian Standards (BIS) specifies IS 4082:1996 for coal crusher design and operational safety.
1. Primary Jaw Crusher:
– Feed size: ≤800mm
– Capacity: 50-800TPH
– Motor power: 75-315kW
2. Secondary Impact Crusher:
– Output gradation: 0-40mm adjustable
– Rotor speed: 500-1200rpm
3. Tertiary VSI Crusher:
– Sand yield: ≥60%
– Max feed size: 50mm
| Equipment | Model | Capacity (t/h) | Power (kW) |
|---|---|---|---|
