Roller mill. 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 ...
