CHAPTER 11 SIZE REDUCTION - NZIFST

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. It implies that the specific energy required to crush a

Introduction to Rock Crushers - ELRUS Aggregate Systems

Jaw crushers offer reduction ratios of up to about 6:1, while cone crushers can reduce material size up to a maximum of 8:1 ratio. The finer the crushing, the smaller the reduction ratio. As a basic rule, jaw crushers are the primary crusher taking the mined aggregate and reducing it to a size that a cone crusher can accept. Cone crushers tend to be the secondary crusher, and
