Rotary scrubber is commonly used ore washing equipment in China and Overseas. It is able to de-slime of the sand and stone, the drum inside is equipped with single or double layer round screen can get 2 to 3 different size of sand stone products, To which is applied pre-concentration of the materials contain mud, to promote the beneficiation index in the later steps and it is widely used to the washing of manganese, iron, limestone, tungsten ore, silica and so on. The slurry material feeds into the drum where it is vigorously scrubbed, the soil matrix is broken up and the target mineral is released. The material is then screened through the rotating screen and waste is ejected. The screened material is then passed on to the concentrating modules for upgrading. 

1)    Designed to break up alluvial gravels, clays & sand.

2)    High capacity and high power scrubbing.

3)    The long drum of the scrubber retains material for longer, more vigorous washing for complete separation.

4)    One high output electrical motor driving a gear system providing efficient torque.

5)    Adjustable rotary speed.

6)    Able to processing material which size up to 230mm

7)    Mechanical sealing of inlet chute – Minimal spillage when over feeding.

8)    Drive loads absorbed within the drive frame and pivoting drive frame design. Foundations only have to support vertical load and are not critical for alignment ie minimal cost.

9)    Shell design less mass than conventional roller supported units – installation craneage requirement reduced.
3.Working Principle

The rotary mining scrubber spins slowly, similar to a giant washing machine. It churns the fines and oversize and water together, vigorously breaking up the soil matrix as well as liberating the target mineral from tough clay, schist's and rock.

After the fine (soil) is separated, the material is moved into the screen. The rotating screen separates the oversize material from the fines (the fines are usually termed or categorized into less than 8mm). Most of the freely (gravity) recoverable gold and or other recoverable mineral is contained in the – 8mm fines.

This material is then passed on to the downstream process equipment which can be in various forms such as centrifugal Concentrator, spirals, jigs etc.
