Granite quarrying and processing involve specialized equipment to produce high-quality aggregates for construction. A typical crushing and sand-making line includes primary jaw crushers, secondary cone crushers, tertiary impact crushers, and sand-making machines.
1. Primary Jaw Crusher:
– Model: PE600×900
– Feed size: ≤500mm
– Capacity: 50-160 t/h
2. Secondary Cone Crusher:
– Model: HPT300
– Max feed: 240mm
– Output size: 10-45mm
3. Tertiary Impact Crusher:
– Model: PF1315
– Capacity: 70-180 t/h
4. Sand Maker (VSI):
– Model: VSI1140
– Throughput: 200-380 t/h
Raw granite blocks are first crushed by jaw crushers, then conveyed to cone crushers for intermediate crushing. After screening, oversized materials are sent to impact crushers or sand makers for final shaping. The output includes 0-5mm manufactured sand, 5-10mm fine aggregates, and 10-31.5mm coarse aggregates.
