Coarse crushing may be required as a premilling initial step to reduce a material to a quarterinch, the largest acceptable mill feed size for most processes. Materials are reduced by fracturing under stress, using compression, shear, or impact forces. Coarse crushing processes can include jaw crushing, roll crushing, and impact crushing.
