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.

1. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill. The number of balls is going to be dependent on the exact size of your drum.

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.
