Modeling Impulsive Ball Mill Forces Effects on the …
This approach is based on a hybrid numerical model of a 24-degree-of-freedom gearbox, simulating one gear train and two drive shafts. The impact forces of the mill drum are modelled by a discrete element method (DEM). The ball-filling rate (Fr), the mill speed (Nr), and the ball size (Db) are considered to study this phenomenon.

Installed power vs pinnion power
The power the mill consumes is a function of the ore and/or ball charge geometry and the mill speed. The motor only supplies the amount of power (or torque really) that the mill demands, and we add some extra power to the motor to deal with 'upset' conditions like a change in ore density or a surge in ore level inside the mill.
