The double helix screw and the grinding chamber are coated with rubber to make them wear-resistant. The ground product is then channeled through a series of two cyclone separators. The fine ground product exits through the discharge outlet, while any oversized material is recycled. (Prasher, C. L. Crushing and Grinding Process Handbook.Web
