Size Reduction - an overview | ScienceDirect Topics
Particle size reduction by mechanical means is called grinding. 2 The objective is to produce a powder with a specific particle size distribution adapted to the subsequent process steps. During grinding, particles fracture when the applied stresses exceed the particle strength globally (massive fracture) or locally (fine wear debris is considered to be formed by attrition).
