Failure of High-Chromium White Iron Shell Liners Due to Mechanical Abuse
Two broken ball-mill liners from a copper-mine ore operation were submitted for failure analysis. These liners failed prematurely, having reached less than 20% of their expected life. The chemical composition of the liners was within specifications for high-chromium white cast iron. The two broken liners were sand blasted for visual inspection and subsequent metallography and hardness testing. Many cracks were found externally and on the undersides. There were also signs of mechanical damage that occurred inside the mill before detection of the failures. The underside cracking is significant because the user advised that the liners were not backed in...
