Can i run a ball mill with a vfd drive

Apr 04, 2020 By controlling a mill with a medium voltage vfd, the speed of the mill is tuned for optimal grinding and maximum throughput, resulting in more efficient use of the grinding power. If up and downstream processes require a lower grinding throughput, the mill can be operated at partial load without having to stop the process

    Mar 20, 2014 A Variable Frequency Drive (VFD) is a type of motor controller that drives an electric motor by varying the frequency and voltage supplied to the electric motor. Other names for a VFD are variable speed drive, adjustable speed drive, adjustable frequency drive, AC drive, microdrive, and inverter.. Frequency (or hertz) is directly related to the motor’s speed (RPMs)
