en The design of autogeneous grinding mills is difficult because of the variability of their grinding media when steel balls or rods are used as in SAG or non-autogenous machines, calculations can be much more reliable because--obviously--the characteristics of the media are constant, or predictable. But when the grinding medium and the feed material are one and the same thing, the variations in the
Jul 20, 2017 In autogenous grinding, there appears to be more abrasion or attrition grinding and less impact grinding than in rod and ball milling. Many of the early autogenous grinding installations in the United States and Canada were used to grind iron ores.
autogenous grinding machines fracture of the media particles also occurs by both impact self breakage and attrition. The relative motion of the media is determined by the tumbling action which in turn is quite strongly influenced by the liners and lifters that are always fixed inside the shell of the mill. Liners and lifters have two main purposes 1.
