The mill suffered extreme erosion at the juncture of the mill shell to the mill head on the discharge end of the mill. The erosion was so severe that cracks occurred at several locations around the circumference. The Metalock and Metalace repair components were able to provide enough strength to withstand the cyclic loading of the mill. Also, the larger repair components are not designed to properly address the direction of strain at this location of the mill. Therefore, the repair consisted of new reinforcement plates to the outer surface of the mill along the outer discharge head diameter.
