Attrition Mill

August 12, 2013

Munson SK-24-MS Attrition MillThe new Model SK-24-MS Attrition Mill from Munson Machinery reduces friable chemicals and minerals, as well as metal powders, wood flour, fertilizers, insecticides and fibers, producing particles within relatively narrow size ranges from 10- down to 100-mesh. The 24-inch diameter mill is equipped with an outer stationary milling disc and an inner rotating milling disc that adjusts to vary the gap between the discs. Material enters the gap through the center of the outer disc and is ground between the discs as it travels radially by centrifugal force created by the rotating disc, with greater reductions achieved by reducing the gap. Capacity is generally dependent on the required output size of the reduced material, with coarser products produced at higher rates.
