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.

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

The design of a ball mill can vary significantly depending on the size, the equipment used to load the starting material (feeders), and the system for discharging the output product. The size of a mill is usually characterized by the ratio “length to diameter” and this ratio most frequently varies from 0.5 to 3.5. The
