AN EXPERIMENTAL ANALYSIS OF VIBRATION OF A BALL

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. Mechanical system of a ball mill
