A modern crushing and sand-making production line is designed to process raw ore or rocks into high-quality aggregates for construction, road building, and concrete applications. Key equipment includes jaw crushers, cone crushers, impact crushers, vibrating screens, and sand washers.
| Equipment | Model | Capacity (t/h) | Power (kW) |
|---|---|---|---|
| Jaw Crusher | PE-600×900 | 50-160 | 55-75 |
| Cone Crusher | PYB1200 | 110-168 | 110 |
| Impact Crusher | PF-1315 | 130-250 | 220 |
| Sand Washer | XS-2600 | 30-60 | 7.5 |
1. Primary Crushing: Large rocks are reduced to 150-300mm by jaw crushers.
2. Secondary Crushing: Cone or impact crushers further break materials into 20-50mm.
3. Screening: Vibrating screens separate aggregates into required sizes.
4. Sand Making: Fine materials are processed by vertical shaft impactors (VSIs).
Semi-mobile plants offer flexibility for mining trailers or temporary sites, while fixed plants suit large-scale quarries with stable output demands.
A granite quarry in Brazil adopted a 200t/h semi-mobile line with jaw + cone + VSI configuration, achieving 0-5mm manufactured sand meeting ASTM C33 standards.
– Excessive wear in cone crusher?
Check liner tightness and feed size; oversized material accelerates wear.
– Low sand yield?
Inspect VSI rotor speed and feed gradation; improper settings reduce efficiency.
