Starting of the mill is possible by either using two of the 1250kVA sets or one 1250kVA and the 500kVA set. No theoretical analysis had been performed on the system, due to being an existing plant. Commissioning on site involved testing the LRS for the correct resistance to ensure the mill motor would develop ample torque to accelerate the mill.

Sep 22, 2018 A typical relationship of motor power/torque output, M1, with mill speed is illustrated for a nominal (or rated) motor speed equivalent to 72% CS. Examples of the power requirement developed by a mill charge as mill speed increases have been added for a 10% v/v ball charge at different total mill charge volumes ranging from 15-30% v/v.

Jan 01, 2018 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.
