In bord and pillar coal mining operations, efficient crushing and sand-making equipment is crucial for processing overburden and waste rock into reusable aggregates. Our tailored solutions optimize resource utilization while maintaining safety standards.

The typical setup includes:
1. Primary Jaw Crusher (JC5460)
– Feed opening: 1400×1100mm
– Capacity: 800-1000t/h
– Power: 400kW
2. Secondary Cone Crusher (HPC400)
– Max feed size: 315mm
– Capacity: 450-600t/h
– Adjustment range: 6-51mm
3. Tertiary VSI Crusher (VSI1145)
– Throughput: 520-640t/h
– Rotor speed: 1700-1900rpm
– Product shape: Cubic
| Model | Feed Size | Output Size | Capacity |
|---|---|---|---|
| JC5460 | ≤1000mm | 150-300mm | 800-1000t/h |
| HPC400 | ≤315mm | 10-51mm | 450-600t/h |
| VSI1145 | ≤50mm | 0-5mm sand | 520-640t/h |

A Queensland-based operation achieved:
– 95% utilization of waste rock
– Annual production of 1.8M tons aggregates
– Reduced haulage costs by 40%
The complete line processes 1200t/h with ≤3% downtime.
