23.09.2014· The gears on the mill on this foundation were very difficult to align and the alignment and vibration of the system was worse when the mill was rotated in one direction rather than the other. We found that the direction of rotation would result in a change in the vibration levels at the pinion piers of up to 7 times depending on the level of damping in the structure (from 5 mm/s to 35 mm/s). .
