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.
