A coal processing plant integrates multiple stages to transform raw coal into marketable products. The crushing and sand-making line is critical for producing graded aggregates. Below is a streamlined flowsheet with core equipment:
1. Primary Crusher:
– Jaw Crusher (Model: JC1200)
Capacity: 800-1,200 t/h | Feed Size: ≤1,200mm | Power: 160kW
2. Secondary Crusher:
– Cone Crusher (Model: CC300)
Capacity: 300-500 t/h | Output Size: ≤50mm | Power: 220kW
3. Tertiary Sand Maker:
– VSI Crusher (Model: VSI-1000)
Capacity: 150-300 t/h | Sand Yield: 60% | Power: 315kW
4. Screening & Grading:
– Vibrating Screen (Model: VS2460)
Layers: 3-4 | Mesh Size: 3-50mm
| Equipment | Model | Capacity (t/h) | Power (kW) |
|---|---|---|---|
| Jaw Crusher | JC1200 | 800-1,200 | 160 |
| Cone Crusher | CC300 | 300-500 | 220 |
| VSI Crusher | VSI-1000 | 150-300 | 315 |
| Screener | VS2460 | -400t/h* |
