Crushers: A Brief Guide to Crushers and Crushing Operations

Essentially, there are four types of crushing operations: shearing, compression, abrasion, and impact. Shearing is a cutting action that cleaves a workpiece between the edges of two surfaces. Compression involves squeezing with a workpiece between two opposing surfaces with increasing pressure until it breaks. Abrasion, or attrition, is a process that churns materials from side to side ...
