The coltan washing trammel scrubber is consisted of two parts: one is for washing the clay, another is for sieving different sizes ores. There are 4 carrier rollers to support the drum. The machine is working rotary through the gear in the middle of the outside drum. In the washing part, it’s a closed space ,there are some plate in this part. When the material is fed from the feeder to the washing part, during the force of watering and striking, the clay and ore will be separated, the fine particle will be flowed ato the sieving part. The sieving screen will separate different size ores, the ore bigger than screen mesh will go to the discharge hopper, and the small ores will be flow out from screen mesh and go to next machine, such as sluice box, centrifugal concentrator, shaking table ect.
