Crushing Vs Grinding

Crushing is performed in several stages, reduction ratios are ranging from three to six in each stage The reduction ratio in grinding can up to 100, therefore it consumes a considerable amount of energy Therefore, the optimization of grinding operation is very important Energy Both crushing and grinding require energy to reduce the ore size...

CHAPTER 11 SIZE REDUCTION

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 111 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 ....
