Log Washers

Utilizing material-on-material scrubbing with water, Log Washers are designed to remove tough, plastic clay contaminants and other deleterious materials from gravel, stone and hard ore feeds. 

McLanahan Log Washers can accept a feed material up to 6″ (150mm) cubed. As the percentage of material to be removed increases, longer units should be used to increase the retention time washing action. In very severe applications, two or more Log Washers may be required.



  • Log shafts are fabricated from extra-heavy, one-piece steel pipe and flanged at both ends to facilitate maintenance
  • Bolt-on, abrasion-resistant paddles are affixed to a twin shaft design to ensure an aggressive washing action that breaks down even the toughest clays
  • Twin-Seal Pak submerged rear bearing assemblies incorporate Caterpillar Duo-Cone® seals that keep water and even the smallest particles from reaching the bearings
  • McL5X paddles are made of specially developed fine grain steel for optimum hardness and maximum abrasion resistance
  • Cleanout gates are available and positioned at the underside of the washer box
  • Spiral or straight row paddle configuration on the shafts are available
