Overcharging results in poor grinding and losses due to abrasion of rods and liners. Undercharging also promotes more abrasion of the rods. The height (or depth) of charge is measured in the same manner as for ball mill. The size of feed particles to a rod mill is coarser than for a ball mill. The usual feed size ranges from 6 to 25 mm.

Unlike ball milling where the whole vessel rotates or oscillate/vibrates whilst in operation, the vessel remains stationary in media milling. Movement of the balls is initiated by a stirring or agitating device, often represented by several discs mounted on a central shaft rotating at high velocities, 20 000 rpm and above, within the vessel.

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.
