Autogenous & Semi Autogenous Grinding Circuits

Autogenous & Semi Autogenous Grinding Circuits

Semi autogenous grinding is applied when fine crushing could cause severe problems or when ore is variable in hardness or competency. Figure 2 shows a typical conventional crushing grinding circuit with three stages of crushing followed by ball mills or rod mill ball mill combination.
