What is Rotary Scrubber
Rotary scrubber named as drum scrubbing machine or drum stone scrubber is a special washing equipment for cleaning large materials that difficult to wash.
Drum stone scrubber has three functions: scrubbing, cleaning and screening. The maximum feed size can reach 200 mm. It mainly carries out preliminary cleaning for raw ore.
The equipment has a large processing capacity, which solves the cleaning of raw ore with high impurity content and mud, and creates favorable conditions for subsequent separation operations.
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%.
Optional trommel screen extensions can be added to the end of cylinder provide primary product separation, screening and dewatering processes.
