Coal Mill Balance moving targetVibration Analysis

I have a coal mill that I am balancing. Do these a lot and normally they are straight forward. This mill was rebuilt with a new shaft and the old wheels and hubs. This has a CCW rotation. Started at 8.5 mils at 130 degrees. I installed 559 grams at 225 degrees. The result started at 9.5 mils at 20 degrees and then over the next 45 minutes walked back to 8.5 mils at 85 degrees. So I Vibration grinding represents an economic and reliable solution since the required product grain sizes can be achieved in a simple continuous grinding process without air classifying.
