The shearing forces (tearing apart), impacting (crushing by outside forces), and attrition (tearing and crushing each other apart) create particle distributions in the nanometer or sub-micron ranges. The media in autogenous grinding can be large pieces of material, so this technique is milling by attrition (self-grinding), not by impact.

Autogenous Grinding

Grinding is easily enabled in autogenous mills by attrition. Also, autogenous mills have grate discharges, so as to retain the coarse grinding media in the mill while dispatching the fine particles. The other benefits of using autogenous grinding include – reduction of metal wear, and elimination of secondary and tertiary crushing steps.
