### THE GRINDING CHARGE OF ROTARY MILLS

material comes in, the grinding is mainly realized by striking, so that the balls with d b = 100 – 110 mm must represent 25–30 % from the charge of this compartment. In compartment 2, (medium grinding), the grinding is realized by striking and friction, so that the balls with db

### 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.
