Chalcocite, a copper sulfide mineral, requires specialized crushing and grinding equipment to liberate copper for further beneficiation. The processing typically involves jaw crushers, cone crushers, ball mills, and flotation cells. Below is a streamlined approach for a sand and aggregate production line tailored for chalcocite ore.
Primary crushing is performed using a jaw crusher (e.g., PE-600×900 with a feed size of 500mm and output of 50-160mm). Secondary crushing employs a hydraulic cone crusher (e.g., HPT300 with a capacity of 120-400t/h). For fine grinding, a ball mill (MQY2740, capacity 10-50t/h) ensures particle sizes below 0.074mm for optimal flotation recovery.
A vertical shaft impact crusher (VSI-1140, capacity 200-400t/h) produces high-quality artificial sand from crushed chalcocite. Vibrating screens (YKN2460, screening area 8.6m²) classify aggregates into 0-5mm, 5-10mm, and 10-20mm fractions.
| Equipment | Model | Capacity (t/h) | Feed Size (mm) | Output Size (mm) |
|——————–|———–|—————-|—————-|——————|
| Jaw Crusher | PE-600×900| 50-160 | ≤500 | 50-160 |
| Cone Crusher | HPT300 | 120-400 | ≤240 | 10-30 |
| Ball Mill | MQY2740 | 10-50 | ≤25 | ≤0.074 |
| VSI Crusher | VSI-1140 | 200-400 | ≤50 | 0-5 |
