Autogenous Grinding & Semi Autogenous Grinding Circuits

Autogenous grinding is favored when the ore is quite competent and a fine grind is required Semiautogenous 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 crushinggrindingAutogenous mills, or AG mills, can accomplish the same size reduction work as two or three stages of crushing and screening Often used in grinding at modern mineral processing plants, AG mills reduce the material directly to the desired final size or prepare it for the following grinding stagesAutogenous grinding mills (AG mills) minevik OutotecAutogenous Grinding a grinding process in which large pieces of the material to be ground—ores and rocksserve as the grinding medium; the process is carried out in drum mills In autogenous grinding, a distinction is made between ore and orepebble grinding Ore grinding is carried out in mills with a large diameter (up to 12 m) and shortAutogenous Grinding | Article about Autogenous Grinding

Autogenous Grinding Mining Fundamentals

Autogenous grinding is a process of grinding ore in a rotating cylinder, using large pieces of the same ore Autogenous mills operate mechanically like ball mills; however, the media used for grinding differs Simply put, in autogenous grinding, the media is also the material that is being ground, whereas in other milling methods steel orThe Barmac Autogenous Crushing Mill is a machine which combines impact crushing, highintensity grinding, and multiparticle pulverizing As such, it is best suited in the third crushing stage or as the first stage of a milling processThe Tidco Barmac autogenous crushing mill A circuitgrinding, to single stage crushing and semiautogenous grinding (SAG) and ball mill (SAB) circuits This progression has, not necessarily, been accompanied by an improvement in the efficiency of power utilisation in achieving the target grind size,Crushing and Grinding Circuit Design
