Size Reduction and Energy Requirement - ScienceDirect
2016-1-1 The chief difference is that in crushing operations the size reduction is more by compression and impact and less by attrition while in grinding; the forces of attrition are much greater. The grinding operation is rather complex and its complexity can roughly be illustrated by Figure 3.3. Download : Download full-size image; Figure 3.3.
