repair ball mill discharge trunnion crack,repairs performed. with the design criteria established the following repair/reinforcement procedures were performed. initially the mill was jacked-up to remove the weight of the mill and the charge from the trunnion. the sections in the upper half of the trunnion that either exhibited cracking or were less than 1.905cm (.75″) thick were removed..typical reason to replace a ball mill trunnion 'unexpectedly',it is unclear if the trunnion damage was known ahead of time and planned for a change-out during the shell reline or if it was discovered during the reline work. while, not knowing if this is the feed or discharge end trunnion, there could be a number of things causing this emergency repair.
