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 pinion bearing.
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.
"The pinion drives the trunnion; it's what makes the ball mill turn. The pinion is a small gear with a matching tooth profile to the ring gear on the ball mill. From a bearing point of view, there are two bearings at the end of the shaft on the pinion and there are two bearings on either end of the ball mill. And obviously, ...

gearboxes, and rolls) and in the flotation plant of ball mills, autogenous mills, and flotation machines (electrical motors and gearboxes). The subject of this case study is the NDE (non-drive end) Pinion Bearing of Ball Mill No 8 in the Mill Dpt. in the flotation plant. The bearings on the pinion are of type 22380YMB.
High vibration on the ball mill drive train A and B. We are experiencing high vibration on our dual drive ball mill. The high vibration is on the motor DE bearing on axial direction. Dominant frequency is girth and pinion gear mesh. See attached spectrums and trends. Gearbox hold-down bolts are breaking due to high vibration.
Ball Mill. We bring forth a highly advanced Ball Mill, specifically engineered for both wet as well as dry cement grinding applications. Classified depending on the circuit design, bearing, grinding type and drive, the selection is made on the basis of the product fineness, quality, and nature of raw material, site conditions and specific requirements.

This case study deals with the successful detection of outer race damage on a ball mill pinion bearing.
The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...

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 1st GMF is predominant. side bands with pinion speed is seen. no GG speed side band was observed
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.
The mill gear should be lifted by the pinion causing a downward pressure on the pinion shaft bearing. Mills are made either right or left "hand". There are two methods of identifying the "hand" of the mill. When standing at the feed end of the mill, and facing the mill, if the mill rotates clockwise, it is a right hand mill.
The pinion is a small gear with a matching tooth profile to the ring gear on the ball mill. From a bearing point of view, there are two bearings at the end of the shaft on the pinion and there are two bearings on either end of the ball mill.

Ball mill is also a widely used machine in the mining industry.Ball mill main bearing, the pinion bearings used in bearing grease, oil pump through a pipeline to oil in the grease nozzle is sprayed onto the bearing by timing supplement bearing grease to keep good lubrication bearing.
Pinion gear is one of the indispensable spare parts of ball mill equipment, according to the direction of tooth shape can be divided into straight teeth and oblique teeth, there are two kinds of key type and expansion type. Different specifications of the ball mill selection of pinion teeth and modulus are not the same.
After the ball mill has been running for a long period of time, the upper tooth surface of the pinion gear is first ground from the concave platform, and the tooth side clearance increases. When the ball mill is running, impact vibration occurs, and a great impact sound is generated, and the wear between the tooth surfaces is aggravated.
