Sag Mill Foundation Design criteria

Grinding Mill Foundations

Sep 23, 2014 · This means that SAG mill foundations behave very differently from ball mill foundations. 4 – Mill Designer Stiffness Criteria One of the mill designers performs a calculation to determine the “target stiffness” of the foundations given the mill and ring motor stiffnesses. We have noticed that this ends up at about 10 MN/mm for large drives.
