How Rotary Scrubbers Work

The rotary scrubbers are supported by four trunnion rollers, and usally installed horizontally or inclined 3-6 degree. When working, the cylinder rotates at a low speed with the motor and reducer driving the large and small gears.

The ore containing mud and stone powder is fed from the feed inlet through the feeding device, and the ore entering the rotary drum is washed by the high-pressure water, materials are constantly lifted, dropped, stirred, so that the ore and mud are completely separated. After fully cleaning, the ore is discharged through spiral discharge liners, the mud content of the ore can be lower than 0.5%, and the water content is lower than 2%.
