THE OPTIMAL BALL DIAMETER IN A MILL - Strona główna

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).
