Log Washers

TRIO's log washers are ideal for scrubbing difficult materials.

Tough insoluble clays, conglomerates, soft stone and cemented aggregates are difficult to clean in normal screw machines. The log washer scours, breaks down and cleans the toughest materials. All TRIO washers are built with large, three-stage gearboxes and outboard lower bearing assemblies.
