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.
APPLIED MINERALOGY IN ORE DRESSING William Petruk CANMET, 555 Booth Street, Ottawa, Ontario, KIA OGI ABSTRACT Mineralogy applied to ore dressing is a reliable guide for designing and operating an efficient concentrator.
