ABSTRACT
Mechanical crushing, the breaking or grinding up of a material to form smaller particles, i.e. comminution, is widely used in both the aggregate-producing industry and the mineral industry. The purpose of crushing is to reduce the particle size of rock materials or to liberate valuable minerals from ores. However, although widely used, mechanical crushing is a complex process that is still not fully understood. At its most fundamental level, all industrial mechanical crushing involves the breakage of individual particles through contact with other particles or with the grinding media, or with the solid walls of the mill.
