autogenous grinding mining fundamentals

Autogenous Grinding - Mining Fundamentals

The term autogenous grinding came about due to the concept of self-grinding of the ore. It is also referred to as "Run of Mine" or ROM grinding. A sturdy, rotating drum throws larger rocks of ore in a cascading motion, causing impact breakage of similar smaller

Small-Scale Continuous SAG Testing Using the Macpherson ...

Fully-autogenous (FAG) and semi-autogenous (SAG) mills were first used on ores in the 1950s, but they were not seriously considered by the mining industry until the 1960s. By the 1970s, most designers of new plants considered AG/SAG grinding, even if it was not used in the final grinding circuit design. In the 1980s, many of the

main components of a semi autogenous grinding mill

Semi-autogenous mills or SAG mills, as they are often called, 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, SAG mills reduce the material directly to the desired final size or prepare it for the following grinding stages.

Autogenous and Semi-Autogenous Mills - ScienceDirect

2016-01-01  These are known as semi-autogenous grinding (SAG) mills. In the mining industry all of these types of mills are in use. 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. Particles at the toe of the mill charge receive the maximum impact forces from falling rocks and other grinding

Ball Mill VS Autogenous Mill-xinhai

The autogenous mill has a wider limit range of material particle size for feeding equipment, which can deal with coarser mineral particle size, which is equivalent to "crushing + a section of grinding", but at the same time, the discharge particle size of the self-grinding machine is also relatively coarse. In general, the larger diameter of the autogenous mill will play a role, so in
