  • Fatigue design of mills ScienceDirect

    Strain-gauge measurements from a large ball mill are presented. Stress ranges determined from these strain-gauge measurements are compared with calculated stress ranges from a finite element analysis of the mill. It is shown that liner stiffness effects can result in lower-than-expected stress ranges at inboard plate flanges in the mill shell.
