Shell-mounted mills with end walls directly above the main bearings are generally stiffer than trunnion-mounted mills. We have checked this by comparing a 26 ft shell-mounted ball mill with a trunnion-mounted mill of equal grinding volume and same diameter. Detailed finite element models of each mill were created.
