The utilization of industrial by-products like slag and iron ore tailings in aggregate production has gained traction due to sustainability demands. A specialized crushing-sand making line transforms these materials into high-performance construction aggregates.
The production line typically includes:
1. Primary Jaw Crusher (PE-600×900)
– Feed opening: 600×900mm
– Capacity: 50-160 t/h
– Power: 55-75kW
2. Secondary Cone Crusher (HPT300)
– Max feed size: 240mm
– Capacity: 120-440 t/h
– Adjustment range: 6-38mm

3. Tertiary Impact Crusher (VSI6X1263)
– Throughput: 250-583 t/h
– Max feed size: 60mm
– Rotor speed: 1000-1700 rpm

| Material | Input Size | Output Size | Moisture Content |
|---|---|---|---|
| Blast furnace slag | ≤500mm | 0-5mm,5-10mm,10-20mm | <8% |
| Iron ore tailings | ≤300mm | 0-3mm,3-5mm,5-16mm | <12% |
Q1: What’s the typical production capacity?
