Abstract: An understanding of torque relationships in the operation of rotary grinding mills necessitates a complete analysis of the mill, gear train, and drive motor insofar as torsional load, inertia, and frictional losses are concerned. Ability of a drive motor to develop the required torque is dependent upon its inherent torque characteristics in combination with its electrical supply system.
