Construction of Rotary Scrubber

The Rotary Scrubber 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 ideal screen size willvary depending on the coarseness of gold found in the area ,If the trommel system is working properly ,all of the fine material will drop  through the screens to be processed, and the larger gravels and rocks will discharge out of the black, completely rinsed and without holding onto any dirt or gravel.

Rotary Scrubber are quite simple to build and work excellent when they are constructed properly. The material come in all different sizes from the small units that can be used efficiently by one or two prospectors using shovels all the way up to huge commercial mining operations feeding them with loaders.

The Rotary Scrubber itself does not separate out the gold. it is simply used to help separate and classify material for the further process. On large 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 simple sluice system to capture the heaviest materials and discharge the lighter sands.

Recovering the gold that has been processed is the same as for any other sluice box . collect the concentrates and use some type of fine gold recovery system to complete the final process and separate the gold.
