Log Washer

The Superior Log Washer is built for material that needs real scrubbing power — rock and gravel loaded with heavy clay, mud, and organic contamination.

Some deposits need more than light rinsing or basic washing equipment. Instead, the Log Washer uses two counter-rotating shafts with aggressive paddles to tumble material, break apart clay-bound lumps, and create material-on-material scrubbing inside the tub. As a result, heavier and cleaner aggregate moves up the incline for discharge, while the water carries away lighter waste, organics, and dissolved clays. In addition, this aggressive scrubbing step prepares difficult feed material before it reaches the screen. Superior positions the Log Washer for tough scrubbing and conditioning applications where operators need to break down caked-on clay and clean difficult feed material.
