Gold Trommel Wash Plant

Gold Trommel Wash Plant Overview

Trommel washing plant is composed by hopper, trommel, chassis, tires, turntable, generator, water pump, gearing, control panel and gold recovery sluice. The mobile trommel screen is a optimized removable platform for gold recovery, applicable to small or medium scale of placer gold ore processing that need mobile operation. Its advantage: less investment, less labor, fast return of investment, simple operation , mobile etc.

A gold trommel is a piece of mining equipment that is quite popular and is used all around the world on all different sized mining operations. Their purpose is to process gold bearing material by separating out the larger rocks and boulders, allowing the smaller material that contains the gold to be run through a sluice box  or other processing system.
Depending on the quality of trommel and the type of material that you are feeding into it, a grizzly may also be used prior to feeding the trommel in order to separate out the largest boulders. This will allow the system to operate at its optimum potential.

After gold bearing gravel is added to the hopper, it enters a rotating drum that further helps to break apart the material. There are generally also water jets inside the hopper, so that there is a combination of high pressure water and the rotating drum which break apart any clays and dirt as the slurry moves through the drum.

The rotating drum is constructed of screen material. This allows the smaller gravel and fines to fall through to a sluice or other processing system, while the bigger rocks will move through the drum and be discharged out the back. The trommel itself does not separate out the gold. It is simply used to help separate and classify out the material for further process. On larger operations, the trommel is generally incorporated into an entire wash plant setup, so that the smaller material that drops through the trommel is run through is simple sluice system to capture the heaviest materials and discharge the lighter sands.
