THE CHALLENGE THE SOLUTION
A ball mill operating in a Queensland gold mine was suffering cracking from mill shell door openings. Using FEA, it was determined that the cracking was fatigue from cyclic operating stresses and that this cracking would continue to reinitiate if repaired. Modifications to the door openings were designed and analysed, and an acceptable fatigue life
