The drive of the ball mill consists of an induction electric motor, two-stage gearbox and the pinion gear. This pinion gear is mated with the girth gear mounted on circumference of the ball mill shell and in that way it transfers the motion from the drive to the shell, see Figure 1, taken from [1].

The action of lifter bars is best understood by following the motion of ball charge inside the mill. There are two well-known modes in which the ball charge moves inside the mill: cascading and cataracting. The cascading motion of ball charge forms a compressive zone inside the mill where particles may break under slow compression.

of the balls is mainly in the direction of the rotation of the mill and not in the direction of the main axis. 2. We consider a perfect layer structure. This means that the balls are lifted up in layers with distance of twice the radius of a ball and with the angular velocity of the mill.

The motion of the charge, that is the grinding media and the material undergoing grinding, within a mill is of considerable theoretical interest and practical importance, and for these reasons, has been the subject of considerable study by a number of workers, but, even so, no rigid and complete theory, covering all the aspects of the dynamics of the mill charge, has yet been produced.

Today, ball mills of 5 m plus are commonplace, and 7 m ball mills are currently employed on at least two sites. However, there are several cases where large ball mills have not achieved design capabilities. One example was the 5.5 m diameter by 6.4 m ball mills at Bougainville Copper Ltd where the coarse material grinding was particularly ...
