Mining comminution – crusher, ball mill, and advanced
Consider the flow that an ore body makes through the mine. Based on the density of the rock body being blasted, the drilling pattern, and a whole host of other factors, there will be a range of rock sizes included in the run of mine (ROM) ore. Smaller pieces will fall through the rock crusher and make their way directly to the SAG mill or ball

Comminution  Wikipedia
Comminution is the reduction of solid materials from one average particle size to a smaller average particle size, by crushing, grinding, cutting, vibrating, or other processes. In geology, it occurs naturally during faulting in the upper part of the Earth's crust. In industry, it is an important unit operation in mineral processing, ceramics, electronics, and other fields, accomplished with

THE OPTIMAL BALL DIAMETER IN A MILL
The bigger ball in relation to the optimal one will have an excess energy, and consequently, the smaller ball mill has less energy necessary for grinding. In both cases, the specific power consumption increases and the grinding capacity decreases (Concha et al. 1992; Katubilwa and Moys, 2009; Erdem and Ergun, 2009).
