For small-scale cyanide processing plants, efficient crushing and sand-making equipment is critical to optimize gold recovery. A compact yet robust production line typically includes jaw crushers, cone crushers, vibrating screens, and sand makers. Below is a tailored solution for processing hard rock or alluvial deposits.
| Equipment | Model | Capacity (t/h) | Power (kW) |
|---|---|---|---|
| Jaw Crusher | PE-250×400 | 5-20 | 15 |
| Cone Crusher | PYD600 | 12-25 | 30 |
| Sand Maker | VSI-7611 | 20-50 | 55 |
| Vibrating Screen | 3YK1237 | 10-50 | 5.5 |
The crushed material (<5mm) is ideal for leaching tanks. Ensure dust control via water spray systems and use wear-resistant liners for abrasive ores. A two-stage crushing circuit (jaw + cone) balances efficiency and particle uniformity.
– Q: How to reduce over-crushing?
A: Adjust the cone crusher’s CSS (closed-side setting) to 10mm and add a pre-screening step.
– Q: Can this line process wet clay ore?
A: Yes, but add a log washer before crushing to remove sticky impurities.
A 50t/d cyanide plant adopted this configuration:
PE-250×400 Jaw Crusher → PYD600 Cone Crusher → VSI-7611 Sand Maker → Heap leaching.
Result: 92% gold recovery rate with <3% -200mesh fines.
For customized layouts, consult local regulations on cyanide use and tailings management.
