The attrition scrubber is also called attrition cell, attrition tank, or attrition machine. It is used to scrub the pulp with a concentration of 65-70% and to scrub the mud and fine sand on the ore. Dispersing the slime in ores to remove the impurities on the ore surface can create conditions for subsequent mineral processing and is an important part of the mineral processing production line.
