The details of the ball mill motor are as follows. Power = kW or HP and the speed is 343 rpm. Load calculations (prior to failure analysis) The ball mill can experience failure based on the maximum normal stress theory as the working loads acting in the ball mill is concentrated across the seam of the mill periphery.

ETAP only simulates the torque vs speed as a curve. Best bet would be to use a torque peak right off zero speed and then drop down to a more constant torque type of load curve. The initial torque to start rotation will most likely be over 100% or rated torque. How much depends on the design of the mill.

Figure 1: Torquespeed curve for asynchronous motors. The starting torque is the torque generated from the initial current inrush, which is always higher than the rated torque. The pullout torque is the maximum torque reached before steadystate, and the rated torque is what is provided once the motor is at 100% speed.
