TGM-1800 Rotating Trommel Screen for Alluvial Gold Mining

Product Overview

Engineered to handle 75-100 cubic meters of material per hour, this trommel features a 1.8m diameter drum fitted with 6-10mm adjustable mesh screens, designed to separate gold particles from sand, gravel, and debris. The stainless steel drum construction resists corrosion from water and mineral-rich sediments, while the energy-efficient 15kW motor minimizes power consumption—critical for remote operations. Its gentle rotating action ensures thorough washing without damaging fragile gold nuggets, making it suitable for both commercial mining and sensitive archaeological site processing.

Features

Continuous Rotary Washing: The drum rotates at 10-15 RPM, creating a cascading motion that prevents screen clogging and improves throughput by 30% compared to static screens.

Versatile Mesh Options: Interchangeable 6-10mm screens allow targeting of gold particles from 0.075 mm (fine flour gold with 6mm mesh) to large nuggets (up to 10mm with 10mm mesh).

Durable Engineering: Stainless steel drum, sealed bearings, and reinforced frame reduce maintenance needs, with an average operational lifespan of 5+ years under heavy use.

Simplified Installation: Requires minimal site preparation—can be mounted on a concrete pad or trailer for mobile use, with full setup completed in under 8 hours.

Applications

Commercial Mining Operations: Processes river sediments, floodplain deposits, and ancient alluvial beds in large-scale gold production.

Desert Gold Recovery: Effective in arid regions when paired with a water tanker, supporting gold extraction in dry environments.

Cultural Heritage Sites: Safely processes historical sediments without damaging artifacts, aiding in both gold recovery and archaeological preservation.

FAQ

Q: Is water absolutely necessary for operation?

A: While it can run dry, water is critical for clay dispersion and gold visibility—reducing recovery efficiency by up to 50% without proper washing.

Q: How long does the stainless steel mesh typically last?

A: Under heavy use with gravel-rich materials, mesh screens last 6-12 months; periodic inspection for tears is recommended.

Q: What are the transport dimensions when disassembled?

A: Breaks into 3 components (drum, frame, motor) with maximum dimensions of 2.5m x 1.8m x 1.2m, fitting in standard trucks or trailers.
