INTRODUCTION. Size reduction is simply the process of reducing/minimizing the particle size of a substance to a finer state of sub-division to smaller pieces, to coarse particles or to powder (fine particles). The term size reduction is applied into all the ways in which particles of solid are cut down or broken into smaller pieces.

Mechanism of size reduction. Size Reduction Materials are rarely found in the size range required, and it is often necessary either to decrease or to increase the particle size. E.g. when the starting material is too coarse, and possibly in the form of large rocks, and the final product needs to be a fine powder, the particle size will have to be progressively reduced in stages.
