Autogenous mills operate mechanically like ball mills however the media used for grinding differs Simply put in autogenous grinding the media is also the material that is being ground whereas in other milling methods steel or porcelain balls are used as media
Autogenous Mills operate mechanically similar to the ball mill They differ in the media they use to break or grind the ore Autogenous Mills use large particles of ore instead of steel or other balls for grinding media Autogenous mills use large pieces of ore as grinding media The grinding is facilitated in autogenous mills by attrition
