WPBM series planetary ball mill has four ball grinding tanks installed on one turntable. When the turntable rotates, the tank axis makes planetary movements and the balls in the tanks grinds and mixes samples in high speed movement. The product can smash and blend various products of different materials and granularity with dry or wet methods.

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.

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.
