McLanahan Coarse Material Screw Washers feature abrasion-resistant, white iron paddles that provide high wear life and are reversible. This gives producers tremendous flexibility, as reversing some of the paddles will keep material in the box longer, improving retention time. If the operator chooses to move the unit or feed it larger amounts of deleterious material, it is still usable despite changing conditions.
The McLahanan screw shaft design keeps operation and maintenance simple on Coarse Material Screw Washers. A 360-degree spiral flight section with wear shoes located at the feed end moves material forward, preventing buildup in that area into a section of scrubbing paddles. Coarse Material Screw Washer shafts are made of extra-heavy steel pipes that have inner and outer renewable and reversible abrasion-resistant hard iron paddles in the scrubbing area. The paddles are followed by heavy-duty steel flights, equipped with bolt-on inner and outer renewable, abrasion-resistant hard iron wear shoes. V-belt drive guarding comes standard for personnel safety. Optional top protective covers are available.
