•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.
On the outside, horizontal grinding mills often face the elements. On the inside, they endure vibration, shock loads, moderate to slow speeds, and a high concentration of particulates. It's a harsh, potentially costly combination. Contamination, lubricant loss, even improper mounting techniques can all lead to failures for pinions or trunnion.
