Descriptions of sand washing machine:
Mine 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 be removed.
