Attrition Scrubbing Machine

An attrition scrubbing machine/scrubber or agitator washer, is mainly used for the dispersion of ore slime, removal and scrubbing of impurities on the mineral surface in the production process of silica sand (quartz sand) or potassium feldspar. It is a mechanical equipment specially used for cleaning and scrubbing high-purity abrasive materials such as silica sand and quartz sand. It is also called “quartz/ silica sand attrition scrubber“- a key equipment used for washing and purification in quartz sand beneficiation. The material feed particle size is usually ≤5mm, and the mud content is high (such as 10%-30%), which requires hydraulic scrubbing to remove mud. Using an attrition scrubber to remove clay, organic matter, and other impurities on the surface of sand, the purity and industrial application value of sand can be improved.

The attrition scrubber is generally used before or after the spiral sand washer in the sand washing plant to scrub the particle surface and decompose impurities. It can also scrub hard ores and aggregates in sand production lines requiring higher quality. The scrubbing machine cleaning process involves strong stirring, and the scrubbed material can increase the recovery rate of mineral processing. According to the specific process requirements, it can be matched with a vibrating screen, spiral classifier, or hydrocyclone for classification and dehydration.
