To achieve optimal copper concentration, a well-designed crushing and grinding circuit is essential. Our turnkey sand and aggregate production line integrates primary crushing, secondary crushing, sand making, and screening processes specifically tailored for copper-bearing ores.
The standard configuration includes:
1. Primary Jaw Crusher (JC5460) – Feed opening 1400×1100mm, capacity 800-1000t/h
2. Secondary Cone Crusher (HPC400) – Max feed size 350mm, discharge range 19-51mm
3. Tertiary Impact Crusher (VSI1145) – Sand making capacity 520-640t/h
4. Multi-layer Vibrating Screen (3YK3072) – Screening area 21m²
| Equipment | Power(kW) | Max Feed(mm) | Output Size(mm) |
|---|---|---|---|
| JC5460 Jaw Crusher | 400 | 1200 | 150-300 |
| HPC400 Cone Crusher | 315 | 350 | 19-51 |
| VSI1145 Sand Maker | 440×2 | 60 | 0-5 adjustable |
Q: How to handle sticky copper ore?
A: We recommend adding a pre-screening module with grizzly bars before primary crushing.
Q: What’s the wear part lifespan?
A: Mn18Cr2 jaw plates typically last 6-8 months processing copper ore at Mohs 4-5 hardness.
Q: Energy consumption per ton?
A: Approximately 3.5-4.2kWh/t for complete crushing and screening.
