The correct operation of a mill with proper load of balls and pulp or ore feed is determined by sound or by power meter. Normally, the sound is a rumble, whereas from a more or less empty mill there is a rattle. The speed of mills depends upon their diameter; a ballmill of 3 feet revolves 35 times a minute, and one of 5 or 6 feet, 29 or 27 times.
