24.05.2019 Dear Analysts, We are facing an issue on our cement plant. It's raw mill main drive motor of 4300kw. On no load condition, vibration is normal but as the feed come, vibration reaches to 4-6 mm/sec (fluctuating between 4 and 6) and whole vibration is on 85Hz (which is natural frequency of end shield bearing housing as told by manufacturer).

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. But maintenance of such rolling mills is a tedious job, because these rolling mills work

Any potential fault will amplify vibration signal’s energy or even distort the vibration waveform and spectrum. The most common faults of industrial equipment can be identified at early stages as they usually distort the machinery’s vibration signature. Therefore, vibration analysis can at an early stage pinpoint issues such as unbalance and misalignment which are the main cause
More15.01.2021 If possible, vibration readings should be taken with the transducer mounted perpendicular to the surface in the horizontal, vertical and axial directions. Vibration signals containing “high frequencies” must be taken with an accelerometer tightly screwed, or glued to the surface, since hand held pressure alone cannot hold it tightly enough to the surface to follow

16.10.2018 Excessive vibrations on rotating equipment like pumps, gearboxes, turbines and compressors are a clear sign that the equipment is not functioning properly. Equipment that is showing excessive vibrations will most likely not achieve the expected lifespan, and can be the source of unscheduled downtime or dangerous situations. Therefore, it is important to find the
