Effects of Ball Size Distribution and Mill Speed and Their Interactions ...

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.

For effective size reduction planetary ball milling is been used here. In planetary ball milling high energy transfer takes place by the action of two centrifugal force acting on the milling balls in opposite direction at the same time. This causes the transfer of energy from impact and shear of balls and powder.
