Just like a bloated stomach, if the amount of grinding exceeds the maximum capacity and discharge capacity, it will cause the mill shell to loses its grinding capacity, and that's why we call it "swollen belly".

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 ...

The cylinder is the container that holds the ball mill grinding process together. We size cylinders by their total volume when empty. When selecting a cylinder, it's important to pick a size that could potentially hold all of your grinding media, raw materials, and 25% of your total volume for processing space—what we consider the "working" area of the ball mill.

A further conclusion from [2] is that the pinion diameter is more important that gear blank profile (Y or T). So, according to [2], the failure of those gears was caused by a design fault, i.e., the diameter of the pinions in the Cadia ball mills are too small.
