By means of a flange type torque sensor, the torque signal is recorded when the motor is driving a constant torque load, (Fig. 1(a)), and a ball mill, (Fig. 1(b)). The presence of an oscillating component of around ± 2 Nm, superimposed to the average value, can be observed in the case of constant torque load.

Now, Click on Ball Mill Sizing under Materials and Metallurgical Now, Click on Shaft Length under Ball Mill Sizing The screenshot below displays the page or activity to enter your values, to get the answer for the shaft length according to the respective parameters which is the Applied Torque (T), Length of Shaft (L), Modulus of Rigidity (G) and Diameter of Shaft (D).

The problem with ball mills vs a simulation like ETAP is that the mill initially is a torque load that is dependent on rotation angle until the charge start to tumble. 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.
