AG Autogenous Grinding - Mineral Processing & Metallurgy

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.

Autogenous Grinding & Semi Autogenous Grinding Circuits

20.07.2017· Professor Marcus Digre in his book on autogenous grinding discusses grinding action in autogenous mills as different from the action in rod and ball mills. He confirms the observation that in autogenous grinding the breakage is principally along grain boundaries and around hard size fractions with little trans-granular breakage.

Autogenous and Semi-Autogenous Mills - ScienceDirect

01.01.2016· Grinding mills in which comminution takes place without grinding aids are known as autogenous grinding (AG) mills or fully autogenous grinding (FAG) 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.

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 of multiples of this basic concentrating unit. Smelters are almost always large because their minimum economic ...

Autogenous and Semi-Autogenous Mills | FLSmidth

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 mill. Via the use of sophisticated instruments ...

Mill (grinding) - Wikipedia

Autogenous or autogenic mills are so-called due to the self-grinding of the ore: a rotating drum throws larger rocks of ore in a cascading motion which causes impact breakage of larger rocks and compressive grinding of finer particles. It is similar in operation to a SAG mill as described below but does not use steel balls in the mill. Also known as ROM or "Run Of Mine" grinding.
