Autogenous Grinding & Semi Autogenous Grinding Circuits
Autogenous Grinding Circuits When an ore is hard and competent, there is always the possibility that it would make good “pebbles” which could be used for fine grinding media Different methods that have been tried using combinations of autogenous, semiautogenous, pebble and/or ball mills The flowsheets shown are typical of the propertiesPilot plant testing for primary autogenous or semiautogenous grinding gives the following information needed for selection of mills, circuit design, and mill design (1), (2) and (3) Since the ore determines the nature of the product from an autogenous or semiautogenous grinding circuit, the first thing to be determined is the suitability ofAG SAG Autogenous & SemiAutogenous Grinding Mill Testing
