recently , we get a new service for balancing a mollases blender .
The shaft its weight 1000 kg with paddles like below picture.
Type balacing: 2 planes intermediates.
diameter the disc for attached balancing weight is 800 mm.
Lenght of shaft is 4 meter.
the issue we meet is our balancing machine suggest to only position at both side .
At the end , we get so much weight to applied to recommend angles.( SEE PICS2)
after that , when we trim vibration to meet the standard (G 6.3 ) it make more vibration .
I checked that the phase at both side ( vertical) is not change only the value is down.
But on the horizon the value is come up !!!
thanks for get some comment!
