There is substantial open literature regarding the structural and mechanical design of large grinding mills. in most cases, published work is in the form of conference papers and mining society journals. it is unclear how many of these papers were peer reviewed prior to publication. there are a number of recurring themes and conflicts in the vendor publications relating to the relative benefits of shell and trunnion-mounted mills, namely

In the following sections, we will show that the disadvantages attributed to shell-mounted mills by trunnion-mounted mill manufacturers are either exaggerated or incorrect and that both mill types can be designed with the same or similar levels of safety.
So, shell-mounted mills with end plates directly above the bearings are stiffer than trunnion-mounted mills but both are stiff enough.
2 8211 the elimination of castings increases the risk in shell-mounted mills svalbonas 1
The arguments for or against the use of castings in mills are not a strong reason to favour or reject shell-mounted mills. this is supported by svalbonas8217 observation that the welds in both shell and trunnion-mounted mill types can be designed to the same level of risk 1.
The larger the bearing surface journal the harder it is to seal. our discussions with operators of large shell-mounted ball mills indicate that whilst the bearing seals leak, they do not a substantial maintenance problem. this may or may not be the case for larger diameter mills but the best people to contact regarding this issue are site maintenance personnel, not trunnion-mounted mill vendors. this issue is not a critical in terms of mill structural integrity.
In 1, svalbonas equates the internal weld at the t-joint with the internal corner welds in older trunnion-mounted mills. these older mills failed prematurely more frequently than modern mills have those with out-turned flanges. svalbonas states that allowable stress ranges at internal weld surfaces of the t-joints must be lower than they are for external welds because they are they are subjected to corrosion, erosion, accidental damage and have a different ratio of tensile to compressive stresses than external welds. there are two problems with this argument, namely
Svalbonas does pull back from this comparison when he states later that both shell and trunnion-mounted mills can be engineered to have the same level of risk. this has been proven recently. the largest shell-mounted ball mills in the world are designed to stress ranges that are less than the allowable stress ranges for internal welds used by both of the us trunnion-mounted mill manufacturers.
What if the mills are segmented axially to facilitate transportation we have undertaken detailed finite element analyses of axially split shell and trunnion-mounted mills. the increase in stress range at the t joint welds in shell-mounted mills is the same as the increase in stress range at internal welds caused by the segmentation in trunnion-mounted mills.
