    Oct 18, 2016 Figure 1 Example plot showing Particle Energy Spectra for a rotating mill. In the plot above, the Y axis gives the Cumulative Power (energy per unit time) resulting from all collisions with specific energies above the respective specific energy value. It accounts for all collisions with specific energy equal to or higher than the specific energy.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).
