The black crushed granite market demands high-quality aggregates for construction and landscaping. A typical production line includes:
1. Primary Jaw Crusher (PE-600×900)
– Feed size: ≤500mm
– Capacity: 50-160t/h
– Power: 55-75kW
2. Secondary Cone Crusher (HPT300)
– Max feed: 240mm
– Output size: 19-38mm adjustable
– Capacity: 120-250t/h
3. Tertiary Impact Crusher (VSI-1140) for shaping
– Throughput: 200-380t/h
– Finished product cubicity ≥90%
