Hot sale high-efficiency spiral classifier(www.ftmmachine.com) is mainly used for sand factory, electric pole factory, worksite of building and concrete dam to wash, classifying and de-watering various sands.This sand washer adopts inclination of 15°, under the water tub, three weir plates from the sediment pool,the screw head is immersed in this pool,the screw is driven by electric motor through reducer rotating continuously,the fresh water is feeding on porous plate at bottom of sediment pool,this machine is three functions of washing,de-watering, classifying
Adjustable wide overflow weir structure makes desliming, dehydration, removing impurity and sand washing more efficient.The machine is equipped with reliable driving and transmission device, special underwater seal structure of the rotary part, which ensures running stable.The spiral blades are made of wear-resistant materials, which ensure working continuity and reduce the running cost.
Hot sale high-efficiency spiral classifier a kind of sand washing appliance by water fit with the sand maker. The sand washer can wash away micro amount of stone powder and impurity from the mixed sand made by the sand maker to improve the quality of the sand. The sand washer impelled by generator and redactor drives the impeller to rotate in circles continuously in the water tank and then to make the sandstones and slag particles mixed, inverted and washed in the tank and discharged after dehydration of the materials in the impeller.
