Hi observing high vibs on pressing and lifting pinion DE and nde bearing on a ball mill. motor and main GB drive are ok. clear predominant gear mesh frequency is appearing in the spectrum along with harmonics and side bands. but gmf is predominant. side bands with pinion speed is seen. no GG speed side band was observed some of the vib data, spectrums and photos shown in the attachment.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 at the asarel medet copper mine. pinion bearing damage in ball mill. using HD measurement technologies, bulgarian copper producer asarel medet AD monitors the mechanical condition of critical equipment in the open-pit mine and flotation plant. this case study deals with the successful detection of outer race damage on a ball mill
ball mill helical pinion gear vibration cause. the cause Of vibration Of ball bearing shell Of ball mill. vibration at the ball bearing housing of the ball mill is a device failure that affects the normal operation of the ball mill there are many reasons for causing lowfrequency vibrations and the vibrations and haards caused by their respective causes are also different.therefore, the equipment temperature can be observedto check whether there is a fault in the ball mill pinion the above four daily inspection records can not only check the ball mill small gear fault, but also check the large gear bearing and other components whether there is a fault, so ball mill is vibration description. ball mill is vibration ball mill vibration monitoring ball mills are a lowspeed application typical rotational speed is 1020 rpm where bearing damage can be challenging to detect condition monitoring of the ball mill began in december 2016 and right from the start the readings indicated potential damage on the output main bearing

the first part of the mill that we will look at is the trunnion bearing. this is a hydrostatic bearing which is a slow moving bearing that carries a heavy load. usually it is constructed from babbitts metal. If you happen to remember the introduction to this course issac babbitt was the man who devised the method of bonding self-lubricating metals onto a strong backing to form a bearing Am sure your ball mill is considered the finest possible grinding mill available. As such you will find it is designed and constructed according to heavy duty specifications. It is designed along sound engineering principles with quality workmanship and materials used in the construction of the component parts. your ball mill reflects years of advancement in grinding principles, materials, and vibration at the ball bearing housing of the ball mill is a device failure that affects the normal operation of the ball mill. there are many reasons for causing low-frequency vibrations, and the vibrations and hazards caused by their respective causes are also different.
