The Characteristics of Comminution with High Pressure Roller Mills

Abstract

High pressure roller mills have been used successfully for grinding brittle materials since 1985- The advantages of this new technology are, less energy consumption, less wear and noise emission and a smaller mill size compared with ball mills. The HP roller mill achieves comminution in a particle bed stressed by a high pressure. The performance of this mill differs from that of a ball mill with respect to the decoupling of throughput and comminution action. To operate a HP-roller mill, one has to understand the features of interparticle breakage, the interdependence of milling force and energy absorption, the capacity issue and the wear problem. © 1991, Hosokawa Powder Technology Foundation.
