GM10 High-Efficiency Gold Trommel for Gold Mining

Product Overview

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.

Product Specifications

Features

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.

Applications

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.

FAQ

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.
