• Ball mill drive motor choicesIEEE Conference Publication

    Abstract The time has come to re-think the approach to mill drive motors because of the growth in size of newer ball mills the starting torque restrictions of some of the newer mill drive configurations and the softness of some utility services. This paper looks at the serviceability and economics of five different mill motor options to meet these restraints. •Additional vibration data was collected from the motor gearbox of the 1A Ball Mill Drive under no load. •To determine what problems (if any) existed with the drive a comparison of the route vibration data between 1A 1B Ball Mills was made as well as between loaded unloaded data at 1A Ball Mill.
