JRaef said: It may not be as simple as a 1:1 HP replacement, you really have to analyze the torque-speed requirements of the Ball Mill before making that decision. A VFD on a standard induction motor is good at making sure the motor can supply a CONSTANT level of torque regardless of speed. But WR motors are capable of providing higher than ...

A ball mill requires higher torque to turn until it reaches a speed where the balls drop onto the down-going side of the mill. Starting torque can also be srongly affected by the position of the ball load in the mill at start and by balls sticking together due to sitting motionless.

I have a ball mill that my brother made. It's a 24" drum by 36" long. It's powered by a gas engine that runs a hydraulic motor. It works really well, but I'd like to convert it to an electric motor. The whole setup is in my shop, and the engine is a bit noisy. I have the ball mill inside an insulated box, so it's actually not to bad.

This soft starter is able to steadily start and stop motor without step change so as to avoid mechanical or electric impact resulted from using conventional starting modes such as direct starting, star-delta starting and auto voltage reducing starting, and effectively reduce starting current and distribution capacity for fear of more investment on capacity expansion.
