China’s small-scale gold production sector demands efficient, modular solutions. A typical setup includes jaw crushers, hammer mills, ball mills, and centrifugal concentrators, designed for 1-5 TPH throughput. Key equipment parameters:
| Equipment | Model | Capacity | Power (kW) |
|---|---|---|---|
| Jaw Crusher | PE-150×250 | 1-3 TPH | 5.5 |
| Hammer Mill | PCΦ400×300 | 2-5 TPH | 11 |
| Ball Mill | MQY900×1800 | 0.65-2 TPH | 18.5 |
| Cen. Concentrator | S-TLF20 | >0.75 kW |
The same crushing units serve dual purposes—gold ore processing and aggregate production. Hammer mills generate 0-5mm sand for concrete, while jaw crushers produce 10-30mm gravel for construction.
– Q: Can this line process hard rock ores?
A: Yes, with tungsten carbide-lined crushers for quartz veins (up to Mohs 7).
– Q: Water recycling options?
A: Modular sedimentation tanks recover >85% process water.
A 3TPH plant achieved 92% gold recovery using:
1) PE-200×350 jaw crusher → 2) Two-stage hammer milling → 3) Knelson concentrator + shaking table combo. Final sand byproduct met GB/T14684-2022 construction standards.
This integrated approach maximizes ROI for artisanal miners transitioning to mechanized operations while complying with China’s environmental regulations on tailings management.
