Several types of ball mills exist. They differ to an extent in their operating principle. They also differ in their maximum capacity of the milling vessel, ranging from 0.010 liters for planetary ball mills, mixer mills, or vibration ball mills to several 100 liters for horizontal rolling ball mills.
From the basic theory and results obtained, it is clear that electrical energy efficiency of the ball mill motor drive is affected by temperature of the trunnion bearings, temperature of pinion bearings, temperature of the mill motor, vibration of pinion gear, vibration of mill motor, tonnage of material fed into the mill (overloading and ...
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 ...
model the mill fill level from the vibration data of the ball mill [14]. The vibration signal obtained from the ball mill was used to model the parameters of the mill load such as pulp density [15].
