    During normal operation the mill speed tends to vary with mill charge. According to available literature, the operating speeds of AGmillsare much higher than conventional tumblingmillsand are in the range of 80–85% of the critical speed.SAG millsof comparable size but containing say10% ball charge(in addition to the rocks), normally, operate between 70 and 75% of the critical speed.
