Highlights We compare strain gauge measurements and calculated stresses for a large ball mill. Measured stresses are lower than calculated stresses at the inboard plate flange. Liner stiffness is the cause of the lower-than-expected measured stresses. We show that mills can be assessed using FEA and modern fatigue design codes. We show that the plate thickness effect is evident in the fatigue
