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 ...
