### calculation of torque on grain 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.

Details >### Torque Calculator

This torque calculator helps you find the torque arising in a rotating object. What exactly is this torque? Imagine an object that can rotate around some point called the pivot point. If you exert a force at some distance from the pivot point, then even though the force will act along a straight line, the object will begin to rotate.
