This paper presents a dynamic simulator of the electromechanical coupling startup of a ball mill. The electromechanical coupling model based on the dynamic model of the ball mill, the characteristic equation of the clutch, and the dynamic model of the induction motor is established. Comparison between the simulation results of angular speed, load torque and current obtained from the model ...

The rod mill motor power is in horsepower at the mill pinionshaft. For different length rod mills power varies directly as rod length. For difference between new and worn liners increase power draw by 6%, and adjust for bulk density per Table A. Wet grinding rod mills are normally used in minerals processing plants.

The poles of the gearless or synchronous motor (also called wraparound motor or ring motor) are directly installed on the pole flange of the mill shell, turning the mill body into the rotor. The stator is then wrapped around the mill. The gearless motor is fed by a cycloconverter which has a rated output frequency of around 5 Hz for the GMD drive.

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.

Effect of Grinding Media Charge on Mill Power Draw kW. Maximum power is drawn by a mill when the charge occupies approximately 50% by volume. The power curve becomes very flat in the range above 45%. As a result, mills are seldom run with charge levels greater than 45%. In rod mills, the charge is swollen by particles of feed which separate the ...
