  • 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).
