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.
Autogenous grinding is defined as a system of grinding in which run of mine or coarsely crushed rock is fed directly to the mill which discharges a finished ground sand or slime product.
Autogenous grinding (AG) mills are tumbling mills which do not require a dedicated grinding media and use the ore itself for grinding. Ores which are comprised of sufficient competent pieces are amenable to AG mills. For such ores, AG mills perform crushing, fine and coarse grinding steps of size reduction.
An Autogenous Milling defined as used in this study, the term Autogenous milling means a process in which the size of the constituent pieces of a supply of rock is reduced in a tumbling mill purely...
Autogenous Grinding a grinding process in which large pieces of the material to be ground—ores and rocks-serve as the grinding medium; the process is carried out in drum mills. In autogenous grinding, a distinction is made between ore and ore-pebble grinding.
This semi-autogenous mill, also called semi-autogenous grinding mill or SAG mill, is mainly used to grind ores and other particulate matter in different fields, like chemical industry, mining field, metallurgy industry, building material sector, and so on. It is an autogenous mill in nature, but it employs grinding balls to assist in its
Nov 26, 2019· AG/SAG is short for autogenous mill and semi-autogenous mill, it combines with two functions of crushing and grinding, uses the ground material itself as the grinding media, through the mutual impact and grinding action to gradually reduce the material size.
Autogenous Grinder Mill Self-grinding machine (AG Mi) and semi-self-grinding machine (SAG Mill) are widely used in power, ferrous and non-ferrous metals mineral processing, chemical, building materials and other industries.
In general, a semi-autogenous grinding (SAG) mill and an autogenous mill are used in the grinding process. A SAG mill grinds through the impact of rock and grinding media, while an autogenous mill grinds only through the impact of rock. An autogenous mill is more suitable for smaller particle size requirements, while a SAG mill is

Other articles whereAutogenous millis discussed: mineral processing:Grinding:Autogenous millsoperate withoutgrindingbodies; instead, the coarser part of the ore simply grinds itself and the smaller fractions. To semiautogenousmills(which have become widespread), 5 to 10 percentgrindingbodies (usually metal spheres) are added.
Themillpower draw, throughput and product size distribution are used to compute a specific energy input and the MacPhersonautogenouswork index (AWI). Although the importance to achieve steady-state in agrindingtest is widely accepted (Bond tests), the MacPherson test remains the only small-scale AG/SAGmilltest that offers this option.

Nov 06, 2019· Even though SemiAutogenous Grinding(SAG) andAutogenous Grinding(AG)millcharges contains less balls and no steel balls respectively, their largemillvolumes can become quite heavy as well. In all three cases (Ball, SAG or AGmill), when the equipment is stopped, the material inside can dry up over time to form a solidified charge.
The semi-autogenous grinding(SAG)millat the MMG Century operation has failing load cells that are essential to the control strategy used to stabilise themill. Currently,mill-bearing pressure is used as a proxy for the load cells, but it has been found to be a noisy signal and lacking in useful sensitivity.
