Mobile Gold Trommel Screen 80TPH 90TPH Gold Separation Equipment

Mobile gold trommel screen

1.Product Introduction Gold Separation Equipment

The Mobile Gold Trommel Screen is a self-contained, highly portable mineral washing plant designed for flexible alluvial gold mining operations. Built on a heavy-duty wheeled chassis or skid, it integrates a feeding hopper, a rotating scrubbing drum, and a water distribution system into a single unit. This mobility allows miners to "follow the gold" by moving the plant directly to different excavation pits or along riverbanks, drastically reducing the cost and time spent hauling raw material to a stationary site.

2.Application Gold Separation Equipment

• Alluvial & Placer Mining: Primary tool for processing river sand, gravel bars, and ancient creek beds.

• Exploration & Bulk Sampling: Ideal for geologists and mining companies to test the gold grade of new claims before investing in stationary infrastructure.

• Small to Medium Scale Operations: Provides industrial-grade washing for operations processing 10 to 150 tons per hour.

• Remote Mining Locations: Designed for "bush" environments where road access is poor and equipment must be moved frequently.

3.Working Principle Gold Separation Equipment

• Mechanical Scrubbing: Raw ore is loaded into the hopper and fed into the rotating drum. Internal "lifter bars" pick up the material and drop it, using the weight of the rocks to break down cemented gravels.

• High-Pressure Washing: A central spray bar runs the length of the drum, injecting high-pressure water to dissolve mud and clay, freeing the gold particles from the waste rock.

• Size Graduation: The drum features screen sections (e.g., 6mm, 12mm, or 20mm). Fine gold-bearing material passes through the screen, while larger "clean" rocks are ejected as tailings via a discharge chute or conveyor.

• Integrated Recovery: The gold-rich slurry is directed into an attached sluice box or centrifugal concentrator. The heavy gold is trapped in specialized riffles or mats, while the waste water and sand exit the system.

4.Advantages Gold Separation Equipment

• Ultimate Portability: Equipped with a tow hitch and heavy-duty tires, the unit can be moved by a 4x4 or tractor, enabling rapid setup and teardown (often in under 30 minutes).

• Exceptional Clay Processing: The rotating action is the most effective way to handle "sticky" ore, preventing gold from being lost inside clay balls.

• High Efficiency/Low Power: Uses a simple drive system (diesel or electric) that provides high torque for tumbling while keeping fuel consumption low.

• Interchangeable Screens: The drum screens can be easily swapped out to match the specific geology of the site, allowing for precision sizing of the feed material.

• Heavy-Duty Construction: Built with wear-resistant steel and reinforced frames to withstand the constant impact of large rocks and the corrosive nature of wet environments.
