A scrubber is a high rpm 'autogenous' mill. A scrubber will rotate at 75% of the 'critical rpm.' The critical rpm is the rpm required for the material to cling to the wall and rotate with the drum without falling. A scrubber uses the large rocks to break up the finer material in the same way a ball mill uses steel balls to break up ore.
