For REMco crushers, the reduction ratio is calculated as the relationship of the maximum feed size to the desired product size. For example, with a feed of -2" and a product requirement of -1/4", the reduction is 2.0 ÷ 0.250 = 8. Maximum recommended reduction ratios for REMco crushers are SandMax – 16:1and RockMax – 8:1.

Abstract. It is well known and taken for granted that the efficiency of energy use by comminution (i.e. breaking, crushing, grinding) equipment is very low, typically less than 10%. Most of the process input power is dissipated as heat and noise and ineffective deformation of the material to be processed and the device itself.
