Attrition Mill Reduces Particles to 100 Mesh

munson0424

A 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 (61 cm) 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. Precise machining and alignment of the discs, together with constant spring pressure, maximize size uniformity of the reduced material, while static and dynamic balancing of the rotating runner head assembly provides vibration-free operation. Plate patterns are selected to optimize the reduction of specific types of materials.

Quick-release separation of the grinding discs allows thorough wash down between product runs.  Access panels can be added to the rear of the housing for cleaning, inspection and maintenance. Models are available with rotor diameters of 12 inches to 36 inches (30.5 to 91.4 cm). They’re also constructed of carbon steel and are available in #304 or #316 stainless steel to sanitary or industrial standards.
