Common bearing failure modes and mechanisms for high ...

Analysis of failure results shows that there are not many quality problems that belong to the bearings themselves, most of which are caused by improper installation and use. For this reason, high-temperature bearings make a superficial review of common bearing failure modes and mechanisms, in order to play a role of attracting a lot of attention.

Study on the Method for Collecting Vibration Signals from ...

At present the method for measuring the fill level which used the vibration signal of mill shell shows its advantage compared with other methods. However, this method is developed late, and the technique for collecting the vibration signal from mill shell is immature. In this paper, a novel method for collecting the vibration data from mill shell is proposed.

The lack of lubrication was originated by a logic failure which allowed the mill to start and run over the trunnion bearing bushing without the lubrication system to be turned on, that is, without oil film. The logic failure was caused by an operator fault. A temperature of 150 °C is enough to meet a stress over the yield strength of the material.
