Motor Sizing Calculations. There are three factors to calculate when sizing a motor; Moment of Inertia, Torque, and Speed. Moment of Inertia. Moment of inertia is the measure of an object's resistance to changes in its rotation rate. When an object is just sitting without any motion, the moment of inertia is 0.

The torque and time requirements of the mill with the ball charge will set the magnitude and time of the inrush current during mill starting. The inertia for this mill reflected to the motor shaft is calculated to be 24,300 ft-lbs2. The time to accelerate the mill to the design speed is given by the following calculation: Time = WK2x Speed Change

of the Bond ball mill grindability test. For all model based methods, a reliable method to calculate mill power draw for a given mill is required for the calculation of power draw. Morrell (1996) proposed a mathematical model for autogenous, semi-autogenous and ball mills which is based on the motion of grinding charge inside the mill.
