Jan 01, 2003 1. Introduction. In comparison to conventional tumbling mills, i.e., rod- and ball mills, the grinding media in an autogenous mill derive from the feed ore itself (Rowland and Kjos, 1978).Any change in feed ore properties will therefore affect the grinding charge and thus, the breakage mechanisms within the mill.
