Log Washers

Log Washers are equipped with replaceable paddles mounted on steel supports that are submerged arc welded to thick, high-grade, one-piece tubular shafts. The high Brinell/abrasion-resistant paddles provide long-lasting protection to the welded paddle spuds by incorporating a wrap-around design. These paddles are heavy section castings with a corrugated surface that rotates stone particles for total surface area scrubbing. Water added to the manifold in the rear of the machine aids in the removal of foreign materials. Soft soluble clays require more water than tough plastic insoluble clays. The tub overflow depth is controlled by side overflow gates. Film and residual matter from the Log Washer’s product discharge can be removed by a rinsing screen.

Log Washers use intermeshing paddles shafts to maximize rock-on-rock scrubbing. The oversized massive paddles with corrugated surfaces force harder sound stones to break down clay and softer, deleterious materials. Material is scrubbed and then conveyed over the machine length to the discharge point, while dissolved clay and other contaminates overflow the weir into a water slurry. Both the size and shape of the material can affect the capacity of a machine. Additionally, changing the slope of the Log Washer can increase or decrease retention time.
