Excessive wear profiles due to long campaigns can cause localized overloads at the barrel ends which favour the initial crack. Continued rolling propagates the crack, exiting at the freeboard and failure then occurs. This is a mill fault. Damage of steel roll due to hydrogen. Hydrogen (H2) can cause two types of problems in steel rolls.

1, ball mill vibration: most of the vibration of ball mill is caused by coupling, motor, reducer and so on. When the clearance of the two wheels of the coupling is too small to compensate for the amount of driving driven by the motor when the motor is started, the transmission coupling of the reducer, motor and transmission shaft does not ...

The following is a list of the most common problems and how they should be resolved. 1. Lack of Procedures. Great lubrication programs are only as good as the people who do the work, just as a chain is only as strong as its weakest link. In many of my most recent projects, the retirement of technicians has been the problem of greatest concern.
