Planetary Mills are ideally suited for fine grinding of hard, mediumhard, soft, brittle, tough and moist materials. The comminution of the material to be ground takes place primarily through the highenergy impact of grinding balls in rotating grinding bowls. The grinding can be performed dry, in suspension or in inert gas.

In total, 165 scenarios were simulated. When the mills charge comprising 60% of small balls and 40% of big balls, mill speed has the greatest influence on power consumption. When the mill charge is more homogeneous size, the effect of ball segregation is less and so the power consumption of the mill will be less affected.

The reasons why the planetary ball mill is difficult to be put into largescale application are that the mass of the tank will necessarily increase and the energy consumption will be huge. Planetary ball milling mainly relies on the centripetal force generated by rotation to drive the movement of balls [11].
