China Gold Washer Drum Rotary Scrubber for Alluvial Gold Washing

Gold Washer Trommel Scrubber
Features:
1) Input size can be up to 230 mm,
2) Large capacity, high efficiency and high power scrubbing,
3) Designed for breaking up alluvial gravels, clays and sand,
4) Longer & more vigorous washing for complete separation.
Description:
The rotary mining scrubber spins slowly, similar to a giant washing machine. It churms the fines and oversize and water together, vigorously breaking up the soil matrix as well as liberating the target mineral from tough clay, schists and rock.
After the fine or 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 actegorized into less than 8 mm). Most of the freely gravity recoverable gold and or other recoverable mineral is contained in the 8 mm fines.
This material is then passed on to the downstream process equipment which can be in various forms as centrifugal Concentrator, Spirals, Jigs, etc.
Working Principle:
The mining drum screen mainly consist of motot, reducer, drum units, racks, etc. Inclination of drum equipment, motor is connected by reducer and drum unit, the drive drum rotate around its axis.
When the materials go into the drum unit, due to the inclination and rotation of drum unit, which makes qualified materials come out by the outer screen, substandard materials come out by the end of rotary screen. This action is repeated with each revolution along the length of the drum. The finer material passes through the screen openings while the larger material tumbles towards its eventual exit at the rear of the drum.
The equipment assembly: Hopper+Trommel Screen(Rotary Trommel Scrubber)+Centrifugal Concentrator+Sluice Box+Shaking Table
Fuction of the equipment:
Hopper: Feeding the material
Trommel Screen: Separating the big particles and the small particles. The big particles will be discharged from the discharge openings of the drum.
Rotary Trommel Scrubber: The function is the similiar with Trommel Scrubber, the difference is the Rotary Trommel Scrubber is used for the material with slurry.
Centrifugal Concentrator: Concentrating the gold from the material which is from the Trommel Screen (Rotary Trommel Scrubber).
Now the gold is the end product, it can be sold. But if you want to increase the grade of the gold, we'd like to advice you can add the following equipment:
Sluice box: Concentrating the gold from the tailings from the Centrifugal Concentrator, cuz there are few gold includes in the tailings. This is for the second gold recovery.
Shaking Table: Increase the grade of the ore from the concentrate gold to separate the impurity.
