The GM-10 is the most advanced portable unit. It is equipped with a reversible wet material hopper and screen. This machine is perfect for small scale operators or acting as a testing plant. Little water is required but it can reach high efficient enrichment capability. It is equipped with a 15cm width sluice box which needs to be cleaned up just when batch test or after one day work. The recovery rate is more than 92%. Recoveryfineness can reach 300 mesh. With continuous processing, advanced reverse screw system, it helps you increase the gold recovery value, and decrease the request to the operator.

The GM10 High-Efficiency Gold Trommel emerges as a portable, compact solution tailored for small-scale alluvial gold mining and field prospecting. Engineered with a reversible wet material hopper (equipped with anti-clogging baffles) and adjustable mesh screen, it efficiently separates gold from clay lumps, gravel aggregates, and fine sand with a steady 10 tons/hour processing capacity. The trommel’s rotary washing drum (48" diameter) integrates 2 cascading washing chambers—the first breaking up compacted sediments with mechanical tumbling, and the second using high-pressure water jets (30 PSI) to dislodge embedded gold particles as small as 0.075 mm. Its aluminum-alloy modular frame allows tool-free assembly and disassembly in under 45 minutes, making it ideal for deployment in remote riverbanks, mountain creeks, or temporary mining sites with limited access.
Parameter | Value |
Processing Capacity | 10 tons/hour |
Drum Diameter | 48" (1.22m) |
Mesh Size | 5-20mm (adjustable) |
Water Pressure | 30 PSI |
Weight | 1.7 tons |
Dimensions | 4.9m x 2.3m x 2.9m |
Rotary Washing Technology: Continuous 360° drum rotation combined with staggered internal lifters prevents screen clogging, improving throughput by 25% compared to static screening systems.
Adjustable Mesh Configuration: Interchangeable 5-20mm screens target specific gold sizes—5mm mesh captures flour gold and fine flakes, while 20mm mesh efficiently processes larger nuggets and coarse sediment.
Low Water Consumption: Optimized water distribution system uses only 300 L/min, making it suitable for water-scarce regions or remote operations with limited supply.
Portable Design: Folds into a 20ft container with secure locking mechanisms, reducing transport volume by 40% for cost-effective shipping and truck transport.
Prospecting Teams: Lightweight frame and quick setup support mobile testing of multiple mineral-rich sites in a single expedition.
Artisanal Mining: Processes river sediments with high clay content, a common challenge in small-scale gold recovery operations.
Construction Waste Recycling: Recovers gold from excavated soil in urban development projects, turning construction byproducts into valuable resources.
Q: Can it operate without electricity?
A: Yes, the integrated 6.5 HP gasoline engine provides independent power, eliminating reliance on grid electricity in remote areas.
Q: What’s the recovery rate for fine gold?
A: Achieves 92% recovery for particles down to 0.075 mm when paired with proper water flow adjustment (30 PSI) and 5mm mesh.
Q: How often should screens be replaced?
A: Under heavy daily use (8+ hours), screens typically last 6-12 months; polyurethane liners can be replaced individually to extend service life.
