Raw Mill Bag House Fan Vibration Critical Issue AMP

I would like to share the vibration trend of our Raw mill Bag House Fan. the fan has been running with abnormal vibration from 4.5 to 7 mm/sec on Horizontal point NDE bearing HH for last 6 months. the main problem is coating and fine dust that is coming from the bag house chambers due to worn and useless bags. this coating build up on fan impeller rapidly and results the fan is unbalance twice in a week. Then we have to stop the fan for a hour and clean the coating

mils is measurement unit for vibration ,what does it mean

01/01/2006 If a the vibration of surface is described as "10 mils pk-pk", that means that the distance between the highest point that the surface reaches and the lowest point is 10 mils, or 0.010 inches. Vibration is more accuractely described in terms of acceleration and frequency; for example, "10 Hz at 0.05 m/s^2 rms". This gets much more complicated when something is vibrating at many different
