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 = K K f c ln(L 1 /L 2) (11.2) Equation (11.2) is a statement of Kick's Law.
