The temperature of the Emax high energy mill was controlled by an internal water cooling system at a constant fluid temperature of 20 °C. The planetary ball mill does not feature active temperature control; therefore, the mill was always stopped after 5 min of processing for a 15 min break, so the overall processing time was 4 times longer.

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 coarse ore from the primary crusher is mixed in the ore bin and then fed into the ball mill together with water for wet grinding. By changing the frequency of the pendulum feeder, we can control the quantity entering the ball mill. The tumbling and crushing action with the grinding medium grinds the coarse ore to finer sizes.
