  • Ball Mill Variable Frequency Integrated Control System

    the variable frequency control technology transforms the ball mill drive system to meet low running speed and high starting torque requirements, and makes ball mill running speed continuously adjustable. there is no shock current when the motor starts running, enough starting torque and full protection functions.the problem with ball mills vs a simulation like etap is that the mill initially is a torque load that is dependent on rotation angle until the charge start to tumble. etap only simulates the torque vs speed as a curve.ball mill torque calculation description torque speed curves ball mill vfd motor is designed in compact and starting torque of ball mill calculation read more, milling the method of powering mills such as ag,sag and ball has a long and technically synchronous motors provide not sufficient torque to start the mill directlyjun 25, 2011 lrs costs in range of lacs. inr however MV vfd starts from range about 1.2 cr. inr. for ball mill starting torque requirement is very high about 0%. pull out torque requirement is also high about 250%. hence, while specifying ball mill motor, pull out torque is generally given as 250% without negative tolerance.
