Naturally occurring deposits of aggregates and minerals hardly ever meet the gradations necessary for use in our daily lives. When aggregates and minerals are initially liberated from the earth, and even after they are crushed in the processing plant, they can contain lumps or coatings of clay, soft rock, vegetation, crusher dust and other deleterious materials that are not desirable in the final product. McLanahan's scrubbing solutions can help producers remove this deleterious material to increase the value of their product.

Attrition Cells/Scrubbers

Attrition Cells/Scrubbers employ particle-on-particle action to liberate deleterious clay and other materials. They can be used in a variety of sand industries and are especially ideal for breaking apart clusters of frac sand material.

Blade Mills

Blade Mills break down deleterious material by means of alternating paddles and flights along a screw shaft. These machines are ideal for removing crusher dust and water soluble clays from coarse rock and sand feeds.

Screw Washers

Screw Washers use a combination of paddles and screw flights to remove light clays, dirt, dust and other deleterious material. These materials are then separated from the feed material by a rising current of water and discharged via overflow weirs.

Log Washers

Log Washers can be used to remove tough clay from aggregate or mineral feeds through material-on-material attrition. Intermeshing paddles on two screw shafts provide additional scrubbing.

Rotary Scrubbers & Rotary Trommels

Rotary Scrubbers and Rotary Trommels employ a tumbling action to remove water soluble clays and coatings from crushed rock, sand, ore and other aggregate material. These machines can accept various tonnages of large-sized material and are ideal for high-capacity applications.
