Rotary scrubber. The rotary scrubber is used to clean and screen ore with large mud content but is challenging to wash. The long washing cylinder allows the material to stay inside for a long time, with a vigorous scrubbing ability. The high-pressure washing water washes the inner wall, thoroughly and powerfully dispersing the material completely.
