The effect of ball size on mill performance  ScienceDirect
The specific rates of breakage of particles in a tumbling ball mill are described by the equation S i = ax α i (Q(z), where Q(z) is the probability function which ranges from 1 to 0 as particle size increases.This equation produces a maximum in S, and the particle size of the maximum is related to ball diameter by x m = k 1 d 2.The variation of a with ball diameter was found to be of the form ...

Effects of mill feed size and rod charges on grinding ...
The effect of reducing mill feed size on product fineness decreases with grinding time, while the effects of different composition of rod charges are very small. Smaller rod diameter, coarser mill feed size and shorter grinding time will increase the energy utilization. The energy consumption in batch grinding is described by the Bond method.

Ball mill  Wikipedia
A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. T
