Mobile Drum Screen

Mobile Trommel Screen: The Ultimate Portable Gold Wash Plant

The Mobile Trommel Screen is an integrated, all-in-one mobile beneficiation system designed specifically for alluvial and placer mining. By combining a hopper, washing drum, grading screen, and gold recovery chutes onto a single wheeled chassis, this Portable Gold Wash Plant allows miners to chase the richest gold veins without being tied down to a fixed plant.

Engineered for the toughest terrains, our Mobile Drum Screen is the perfect solution for small to medium-sized operations, river panning, and remote exploration sites. It offers three core advantages: rapid relocation, flexible off-grid operation, and an exceptionally fast return on investment (often recovering its cost within 3 to 6 months).

Whether you are dealing with loose river gravel or sticky clay, this Portable Trommel Wash Plant ensures high throughput and maximum fine gold recovery directly at the mining face.

Why Choose Our Mobile Placer Gold Equipment?

• Heavy-Duty Mobility: Built on a robust 6-tire chassis (with 180° front-wheel steering) and equipped with 4 hydraulic outriggers. It can be towed by a standard loader or excavator and leveled for operation in under 30 minutes.
• Off-Grid Power Ready: We understand remote mining. These units can be configured with dual power options—either driven by an onboard diesel generator or directly powered by diesel engines, ensuring non-stop operation anywhere.
• High-Recovery Gold System: The undersize discharge is fed directly into built-in sluice boxes lined with professional gold-trapping carpets (miner's moss). This dynamic system captures over 85% of fine gold (down to -0.1mm).
• Double-Layer Composite Drum: The heavy-duty drum features an inner steel bar grizzly (to absorb the impact of large boulders) and an outer high-manganese steel or PU screen mesh, extending the service life by 3 times compared to standard screens.

How the Portable Wash Plant Works

1. Loading: An excavator or wheel loader dumps raw, gold-bearing gravel into the receiving hopper. A grizzly over the hopper prevents massive, uncrushable boulders from entering.
2. Washing & Screening: High-pressure water jets inside the hopper and the rotating drum break apart dirt and clay. The drum tumbles the rocks, thoroughly washing them.
3. Separation: Small, gold-bearing particles fall through the screen mesh. The washed, oversized rocks tumble out the back of the drum into a waste pile.
4. Gold Recovery: The fine, muddy slurry that passed through the screen flows directly over the attached sluice boxes. The heavy gold particles sink and are caught in the specialized gold carpets, while the lighter sand washes away.

Ideal Scenarios for Mobile Trommels

This equipment provides ultimate flexibility for:

• River Gold Panning & Alluvial Mining: Easily move the plant along the riverbank as the working face progresses.
• Exploration & Sampling: Quickly process bulk samples across different areas of a concession to map out gold concentrations accurately.
• Artisanal & Small-Scale Mining (ASGM): A professional, high-capacity upgrade from manual sluicing, offering rapid setup and immediate cash flow.
• Tailings Reprocessing: Efficiently move through old mining dumps to recover fine gold missed by older technologies.
