9.3.4 Mill Speed. During normal operation the mill speed tends to vary with mill charge. According to available literature the operating speeds of AG mills are much higher than conventional tumbling mills and are in the range of 80–85 of the critical speed. SAG mills of comparable size but containing say 10 ball charge in addition to the rocks normally operate between 70 and 75 of the critical speed.
