reduction cycle. Generally gyratory crushers, jaw crushers, high speed double roll crushers, low speed sizers, impactors and hammer mills are used as primary crushers. In the secondary and subsequent stages, the material is further reduced and refined for proper size and shape, mostly based on specifications.

Roll crushers apply shear or compression to the material that is going to be reduced in size. This action occurs between two hardened surfaces. The speed and diameter of the rolls, the desired capacity, and the feed and product size distribution are all critical in the proper sizing and operation of this type of machine.

A theoretical approach to determination of particle size distribution of crushing products was presented by Kolmogorow (1941) and Epstein (1947), who proved that for a multi-stage comminution process, the particle size distributions of products are log-normal. The product particle size distribution depends on the crushing process intensity (stage).
