The power the mill consumes is a function of the ore and/or ball charge geometry and the mill speed. The motor only supplies the amount of power (or torque really) that the mill demands, and we add some extra power to the motor to deal with 'upset' conditions like a change in ore density or a surge in ore level inside the mill.

If your motor has an efficiency of and you measure 1000 kW at the motor input, then the motor output power you would measure (with a torque device) is 900 kW. This is why you are measuring more input power than the rated power; the rated "input" power would be 1500 HP divided by the motor efficiency.
