2020-3-1 · Particle size reduction in a roller mill is achieved by compression (same roll rotating speed) or shear (different roll rotating speed) forces and the roll design features (grooves and corrugations) (Koch, 2002; Vukmirović et al., 2017). This has made the roller mill suitable for very accurate controlled milling of the product, although it has ...
Read MoreFor example, in most roller mills compression is the dominant force, impact forces feature strongly in hammer mills and shear forces are dominant in disc attrition The extent of the breakdown of a material may be expressed by the reduction ratio , which is the average size of the feed particles divided by the average size of the products particles.
