Pakistan’s marble industry generates significant waste powder during cutting and polishing. Efficient processing of this byproduct into high-value construction materials requires specialized crushing and sand-making equipment. Here’s a tailored solution:
1. Jaw Crusher (Primary Crushing)
– Model: PE-400×600
– Feed size: ≤340mm
– Capacity: 16-64t/h
– Power: 30kW
2. Impact Crusher (Fine Crushing)
– Model: PF-1214
– Rotor diameter: 1250×1400mm
– Capacity: 70-130t/h
– Power: 132kW
3. VSI Sand Maker (Powder Shaping)
– Model: VSI-7611
– Throughput: 60-180t/h
– Max feed size: 50mm
– Power: 110kW×2
Raw marble powder → Vibrating feeder → Jaw crusher → Belt conveyor → Impact crusher → Vibrating screen → VSI sand maker → Finished product (0-5mm artificial sand)
| Equipment | Output Size | Moisture Tolerance | Silt Content Control |
|---|---|---|---|
| Jaw Crusher | 50-100mm | <8% | – |
| Impact Crusher | 10-30mm | <6% | – |
| VSI Sand Maker | 0-5mm | <4% | <3% |
Q1: Can marble powder replace natural sand completely?
A: Partial replacement (30-50%) is recommended for optimal concrete strength.
