AThe process of ball milling and the materials that compose planetary ball mills are highly complex, and the existing research on the change in ball-milling energy is not mature. The theoretical model of a ball mill was established for the first time to simulate the motion, collision process, energy transfer, and temperature change of small balls during Model Study of Mechanicochemical Degradation in a Planetary Ball Mill

In AG/SAG-based circuits the need for W s appears to be unnecessary as Fig. 2 illustrates. Primary crusher feeds often have the shape shown in Fig. 2 and this has a very similar gradient to typical ball mill cyclone overflows. A similar situation appears to apply with HPGR product size distributions, as illustrated in Fig. 3.Interestingly the author’s A ball mill is a type of grinder used to grind materials into extremely fine powder for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering.
