Mill finds good housekeeping can reduce vibration, case study It was pretty hard for anyone in the machine room not to notice the vibration coming from No. 5. It had become so that the floor actually shook. The vibration seemed to be coming from the gearboxes at the pull stack and reel.
The work reported here is essentially an extension of the above study providing information that will aid the diagnosis, using vibration analysis, of some of the common faults occurring in the same machines (using the coal mill main drive assembly and bag house/booster fans as illustrative examples).
The vibration signals were then collected by an accelerometer mounted directly on the mill shell, and analyzed on the time domain to obtain the maximum vibration point on the mill shell, in order .
Vibration Based Condition Monitoring of Rolling Mill V inod D.TIrpude, Jayant P.Modak, Girish D. Mehta Abstract: All over the India, most of the processing industries are involved with rolling operations for steel and alloyed materials. To perform these operations, rolling mills are used.
ABSTRACT In the present case study, the causes of the hi gh vibrations on a double-drive cement mill is investigated by performing a series of vibrat ion measurements on the cement mill pinion and.
testing the standard case was chosen to be that of wet grinding. The charge volume and proportion of media in the charge. The charge volume of a tumbling mill is the volume of the mill interior filled with grinding media. Overflow ball mills are restricted to having a maximum charge volume of approximately 45~0 to prevent balls discharging.

Advanced vibration analysis was performed on the blower and supporting base structure to determine the root cause of the elevated vibration levels that were affecting this equipment. Bump Testing A bump test was performed to determine the natural frequencies of the base structure and ensure that these frequencies were not within 10% of any .
