  • ETAP Motor Starting Study for 600kW Ball Mill Electric

      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 Best bet would be to use a torque peak right off zero speed and then drop down to a more constant torque type of load curve
