Modern gold wash plants are engineered for high-efficiency recovery of placer gold and heavy minerals. A typical setup includes a trommel screen (10-50 TPH capacity), sluice boxes with riffles, and centrifugal concentrators. Popular models like the MSI T8 (300 TPH) feature modular designs with adjustable angle screens (5°-7°) and water consumption of 800-1,200 GPM.
For hard rock gold processing, jaw crushers (PE-600×900) primary crushing and cone crushers (HPT300) secondary crushing are paired with VSI sand makers (750 rpm) to produce 0-5mm manufactured sand. Key parameters:
| Equipment | Power(kW) | Capacity(t/h) |
|---|---|---|
| Trommel Screen | 15-45 | 50-300 |
| VSI Crusher | 110-315 | 60-520 |
| Dewatering Screen | 7.5-22 | 20-150 |
Q1: What’s the lifespan of trommel screens?
A: 5-8 years with proper maintenance using HARDOX 400 liners.
Q2: Can wash plants process clay-rich material?
A: Yes, when equipped with log washers or scrubbers (20 RPM).
A 200TPH alluvial gold plant in Laos combines a GT2055 trommel (45kW), Knelson CD12 concentrator, and dewatering cyclones. Achieved 92% recovery rate for +0.074mm gold particles with water recycling system reducing consumption by 40%.
