modal analysis of ball mill foundations events

2016 10 19 with this design in the event of some movement the mill and foundation will tend to move as a unit any slight settling of foundations will cause bearing and gear misalignment resulting in excessive wear and higher maintenance costs it has been found that concrete foundations on a weight basis should be at least 1 times the total weight.
