autogenous grinding mechanism

A Load-Interactive Model for Predicting the Performance of

autogenous grinding designates generically the action of rocks grinding upon themselves, as occurring in tumbling mills. For reasons that will be further ad-dressed in this work, grinding in autogenous (AG) mills is frequently assisted by steel balls, in which case it is called semi-autogenous (SAG) grinding.

TECHNICAL NOTES 8 GRINDING R. P. King Mineral Tech

In 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.
