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

A general rule of thumb for applying Cone Crushers is the reduction ratio. A crusher with coarse style liners would typically have a 6:1 reduction ratio. Thus, with a 3⁄4” closed side setting, the maximum feed would be 6 x 3⁄4 or 4.5 inches. Reduction ratios of 8:1 may be possible in certain coarse crushing applications.
