Mill Charge - an overview | ScienceDirect Topics

Since grinding effort is related to grinding energy, there is little increase in efficiency (i.e., delivered kWh t −1) above about 40–50% of the critical speed. It is also essential that the cataracting medium should fall well inside the mill charge and not directly onto the liner, thus excessively increasing steel consumption.
