increasing energy consumption with increasing mill productivity. The increase in the mass of ball mills occurs due to the crushed material supplied to the mill - ore and pulp. In a ball bed mill, the pulp volume reaches approximately 60-70% of the drum volume, which is separately occupied only by the ball load.

To support this process, Retsch has designed a spider-net diagram that displays the strength and efficiency of each ball mill model, as shown in Figure 3. For example, a planetary ball mill has a bigger jar volume compared to a mixer mill; this is shown by its high value on this diagonal in the spider-net diagram.

In terms of this concept, the energy efficiency of the tumbling mill is as low as 1%, or less. For example, Lowrison (1974) reported that for a ball mill, the theoretical energy for size reduction (the free energy of the new surface produced during grinding) is 0.6% of the total energy supplied to the mill setup.
