Ball Mill Drive Motor Bearing Vibration. High Vibration Ball Mill Duel Pinion Drive Mechanical . A vibration survey was carried on this Ball Mill with a duel pinion drive The vibration is high in all planes on both sides of the Mill or both pinion drives The measurements were similar in velocity on the motor , gearbox and both pinion bearings

Ball Mill Pinion - Vibration Analysis & Machinery ...

So it is a large synchronous motor coupled to a stub shaft, coupled to the pinon and it meshes with the bullgear that is on the outer circumference of the mill. Pinion speed is indeed 180. Bull gear tooth count is 241. I had a cage failure on one of the pinion bearing 2 years ago, at that time we replaced both bearings.


•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.

High Vibration Ball Mill Duel Pinion Drive - Mechanical ...

A vibration survey was carried on this Ball Mill with a duel pinion drive. The vibration is high in all planes on both sides of the Mill or both pinion drives. The measurements were similar in velocity on the motor, gearbox and both pinion bearings. The recommendations for repairs was close to exactly the same for both drives.


ball mill. After that the measurement of accelerations of vibration at housings of bearings has been performed. Due to the production requirements the capacity of the ball mill is variable and therefore the torque on the ball mill drive is also variable. Measurement has been done for two different capacities.

Pinion bearing damage in ball mill - SPM Instrument

This case study deals with the successful detection of outer race damage on a ball mill pinion bearing. On the non-drive end bearing, the Intellinova online system initially indicated shock pulse levels that varied between green and yellow condition evaluation. This fluctuation was attributed to the operating conditions, with varying loads on ...


noise, vibration and temperature. When one or more of the preceding operating characteristics exceeds allowable limits, the drive and its application should be examined to determine the cause of the problem. Gear drive components most commonly subject to distress are the gears, shafts, bearings and seals. The purpose of this stone is to ...

Gearless mill drives - Grinding | ABB

Our GMD eliminates all mechanical components of a conventional mill drive system, such as ring-gear, pinion, gearbox, coupling, motor shaft and motor bearings: By mounting the rotor poles directly onto the mill, the mill itself becomes the rotor of the gearless motor.
