The TLW log washers are ideal for scrubbing very difficult materials. These machines will scour, break down and clean the toughest materials, such as insoluble clays, conglomerates, soft stone and rock, and even certain cemented aggregates all considered too difficult a task for conventional screw machines. These log washers use the same outstanding features found in our fine and coarse washers, such as heavy duty conveying paddles, a rising column of water, and heavy duty tubs, oversize bearings and gears. Heavy duty, replaceable shoes provide a long operating life and protect the shaft and tips from long term wear and tear. Each cast shoe has a corrugated surface to promote the most severe scrubbing action. Tubular log shafts are also designed to be considerably stronger than traditional rectangular shafts. The compound drive divides the operating load over an optimal combination of helical and spur gears, each oversized to ensure maximum.
