Autogenous Grinding & Semi Autogenous Grinding Circuits
20-07-2017· An autogenous or semiautogenous circuit, as the name implies, uses the ore itself to assist in the grinding process. In this type of circuit, the ore must be competent so large chunks of ore can be used to grind smaller chunks of ore. https://www.911metallurgist/equipment/autogenous-mill/.AG Autogenous Grinding - 911 Metallurgist,06-08-2015· Autogenous grinding tests were run in a 10-ft x 4-ft Rockcyl mill. The principle of prepared feed and media was utilized to determine how coarse a feed could be commercially fed to a rock mill. Secondary rock milling was expanded toward the particle sizes of primary milling while still utilizing the practices of secondary milling.Semi Autogenous Grinding Mill - an overview,,Concentrators vary similarly. A new large concentrator unit typically consists of a semi-autogenous grinding mill, high pressure grinding rolls, two ball mills, and a flotation circuit. It can treat up to 170 000 tonnes of ore per day (Sartain, 2010). Larger concentrators consist ofAutogenous Grinding Mill | Sepor, Inc,Designed for autogenous or semi-autogenous grinding, the 6′ X 2′ continuous feed Autogenous or Semi-Autogenous Mill may be used as a pilot plant to determine the size for larger mills or for small scale milling projects.
