The ball mill has higher circulation load it generates only 30 35 of actual fines you require to be called as product. If your product size needed is 100 passing 45 micron then the ball mill total discharge material will contain normally 30 of 45 micron. The rest is oversize which has to be ground again.

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 . Figure 1.
