CPE: Lesson 13. Principle of Size Reduction

Size reduction of solids involves creating smaller mass unit from larger mass units of the same material. Size reduction is a mechanical process of breakdown of solids into smaller size particles without altering the state of aggregation of solids. Many solid materials exists/present in sizes that are too large to be used directly.

CHAPTER 11 SIZE REDUCTION - NZIFST

2019-2-24  Kick assumed that the energy required to reduce a material in size was directly proportional to the size reduction ratio dL/L. This implies that n in eqn. (11.1) is equal to -1. If K = K K f c where K K is called Kick's constant and f c is called the crushing strength of the material, we have: dE/dL = -K K f c L 1 which, on integration gives: E ...
