Autogenous Grinding - Mining Fundamentals

Autogenous grinding is gaining in popularity, as the grinding media costs are much less, and this process does not produce as much slime or fines as traditional rod and ball mills. Autogenous mills can handle both wet and dry operations. In some applications that require the grinding of minerals, such as talc, asbestos, and mica, dry semi-autogenous milling is the preferred choice. Grinding is ...

Autogenous Grinding Article about Autogenous Grinding

In autogenous grinding, a distinction is made between ore and ore-pebble grinding. Ore grinding is carried out in mills with a large diameter (up to 12 m) and short length (the ratio of diameter to length is approximately 3). Ore with pieces having dimensions up to 300 mm (sometimes, up to 600 mm) is loaded into the mill. If only a small amount of the large fraction is present in the ore ...

Mill (grinding) - Wikipedia

SAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in diameter, powered by a

The disintegration and size reduction of ores in AG/SAG mills is brought about by a combination of impact, attrition and abrasion forces during mill rotation.

The MacPherson Autogenous Grindability test is performed with a light ball charge (8%), so it is actually a SAG mill test, but the results from the test have been used for the analysis of both fully-autogenous (FAG) and semi-autogenous (SAG) circuits (the fine feed size to the mill would not generate sufficient impact energy in FAG mode). In this paper, for ...

Autogenous mill is a kind of ore grinding equipment with the function of crushing and powder grinding. It used the grinded material as a medium through mutual striking and grinding to finish crushing. Autogenuo grinding feeds the large ore with the maximum size up to 300mm - 500mm directly into the autogenus mill. Due to the different blocks of ore driven in the grinding equipment generate the ...
