This is an update of work presented at the SAG 2001 conference on the Cadia gears [1]. Both gears and pinions on twin ball mills failed almost simultaneously. Our 2001 paper showed that the location of the failures is explained by the shape of the girth gear blanks. Fresko et. al. [2] shows that T-gears are in fact better than Y-gears in terms ...
