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 ball-mill of 3 feet revolves 35 times a minute, and one of 5 or 6 feet, 29 or 27 times.

The bauxite feeding amount was to cover the gaps among the balls (3500 g).
Bauxite grinding mills operate through a combination of impact, compression, and attrition forces. In a typical setup, bauxite ore is fed into the mill, where steel balls or other grinding media crush and grind the ore particles. As the mill rotates, the grinding media cascade and collide with the bauxite, gradually reducing its size.
