Regarding the energy consumed during the ball milling tests carried out, Fig. 11 shows the temporal evolution of the mill power draft characterizing both batch and continuous experimental tests. Concerning the batch milling tests, specifically, Fig. 11 (left) shows that, when using different mills speeds, relatively large differences in energy consumption appear.
