MECHANICAL MILLING Crushing/Pulverizing (and Pre-crushing) Coarse crushing may be required as a pre-milling initial step to reduce a material to a quarter-inch, the largest acceptable mill feed size for most processes. Materials are reduced by fracturing under stress, using compression, shear, or impact forces.

Consequently, in most operations, crushing plant opera- tors produce mill feed as fast as possible. But the fastest feed rate produces the coarsest material, causing any sub- sequent milling operatior1 to have the lowest output and maximum unit cost, both in terms of power as well as mill media and liner consumption.
