What is an Attrition Mill and How Does it Work?

Materials Attrition Mills Best Handle . Attrition mills are well suited to process brittle or fibrous materials that need to be within a comparatively narrow particle size range. Attrition mills are used in the production of: Blended materials, including face powders and certain insecticides. Fibrous materials like cellulose, cork, and wood chips.

High performance attrition in stirred mills

Attrition is applied to sandy material to remove particle surface contamination or undesired cuttings before flotation. Working in stirred mills and applying special process conditions, attrition can be intensified enabling abrasion of particles in the size range between 20. μm and 1000 μm.. Subsequently, the resulting highly …
