Building Industry concrete aggregate /fine sand washing machine

Spiral Sand Washing Machine are ideal for scrubbing difficult material. Tough insoluble clays, conglomerates and soft stone, and certain cemented aggregates are too difficult to clean properly in normal screw machines. The log washer thoroughly scouring, breaks down, and cleans the toughest materials. These high quality, highly durable machines perform well under the toughest clay conditions with minimum power, water and downtime.

Feed material is normally delivered between two to four feet from the feed end of the box and is subjected to an aggressive washing action resulting from the intermeshing paddle design. The paddles perform two functions: they help convey material and are the catalyst to material on material scrubbing. The clean material works uphill, between the shafts, and is discharged out the bottom of the box. Deleterious materials are absorbed into water and carried over a weir on either side of the box. The length of the washer box is dependent upon the percentage and tenacity of clay or the waste to removed.

Working principle of  Building Industry concrete aggregate /fine sand washing machine

The spiral classifier mechanically classifies through the mechanism of different sedimentation speed of solid particle in liquid due to different size and different specific gravity: the fine ore grain floats in water for overflowing; and the coarse one sediments onto tank bottom and then is pushed upwards by spiral for discharging. It can classify the ground material powder from the grinder, spiral the coarse grain into material inlet of grinder through the spiral chip, and discharge the classified fine grain from overflow surface.
