Silica sand processing requires specialized pulverizers and crushing-screening systems to achieve optimal particle size distribution for construction aggregates or industrial applications. Key equipment includes jaw crushers, cone crushers, VSI impact crushers, and high-pressure grinding mills.
| Equipment | Model | Capacity (t/h) | Power (kW) |
|---|---|---|---|
| Jaw Crusher | PE-600×900 | 50-120 | 75 |
| Cone Crusher | HPT300 | 80-200 | 315 |
| VSI Crusher | S8-1145 | 60-150 | 250×2 |
| Raymond Mill | 4R3216 | 3-8 | 37 |
A typical silica sand processing line adopts three-stage crushing:
1. Primary crushing with jaw crusher (<50mm output)
2. Secondary crushing via cone crusher (<20mm)
3. Tertiary shaping with VSI crusher (0-5mm adjustable)
Q: How to control silica dust?
A: Install pulse dust collectors (filter efficiency >99%) at transfer points.
Q: Minimum finished product size?
A: VSI crushers achieve 0.15mm with specialized rotors.
