1/1/2016· Grinding mills in which comminution takes place without grinding aids are known as autogenous grinding mills or fully autogenous grinding mills. These mills use large lumps of rock as the grinding media. Mills that use intermediate size rock or pebbles as a grinding medium are also autogenous mills but are known as pebble mills. Mills that grind hard ores with fracture characteristics that do not lend themselves to fully autogenous milling
20/7/2017· 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. equipment/autogenous mill/.
Semi autogenous grinding uses a minimal ball charge in the range of 6 15% while autogenous grinding uses ore only. SAG and AG Mills operate by lifting ore/grinding media and dropping it on the operating bed of the mill charge. High impacts from lifting ore and media promote impact breakage which is the primary mechanism for size reduction in the ...
