Coal mill rejects from cement plants, often considered waste, can be repurposed into high-quality sand and aggregates through specialized crushing systems. This approach reduces landfill costs while creating value-added products for construction.
A typical production line includes:
1. Jaw Crusher: Primary coarse crushing (Feed size: ≤800mm, Output: 50-200mm)
2. Impact Crusher: Secondary fine crushing (Capacity: 50-400t/h)
3. VSI Sand Maker: Shaping (Finished sand 0-5mm, shaping rate >90%)
4. Vibrating Screen: Multi-layer screening (3-4 decks)
| Equipment | Model | Power(kW) | Output(t/h) |
|---|---|---|---|
| Jaw Crusher | PE600×900 | 75 | 50-160 |
| Impact Crusher | PF1315 | 220 | 130-250 |
| VSI Crusher | S8-1145 | 250×2 | 70-140 |
| Screening Machine | 3YK2460 | 30×2 | – |
