The Powerscreen Finesmaster Powerscrub range takes washing one step further by providing high speed scrubbing of heavily contaminated material to produce cleaner material at a faster rate. The Powerscreen Finesmaster Powerscrub range is designed with a trough and two axles with interlocking blades and paddles which intensively mix the material. Friction from this process breaks down feed contaminates and allows Scrubbed material to be stockpiled.
