Intermediate autogenous mills (or intermediate pebble mills) which process a fine crushed product (minus 5/8″ to minus 1″) obtained from an intermediate crushing plant. The grinding media in these mills are rock pebbles of suitable size (3″ to 6″) screened out of the intermediate crushing circuit.
Autogenous grinding mill: in this grinding mill, rotating drums throws in large balls of matter in a rapid motion. This causes the ball to break and make smaller particles. SAG mill: SAG is the short form of semi autogenous grinding. The difference between autogenous and SAG mills is, it uses balls to grind like ball grinding mill.
Semi-autogenous grinding (SAG) and autogenous grinding mills are used for grinding large chunks of materials into smaller pieces which can be later used for processing. Such mills are used in the primary stage of grinding process where pieces of raw materials need to be grounded for further processing or sorting.
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.

Over the years the design and operation of single stage autogenous and semi autogenous grinding mills has been a rather hit and miss affair, with some great successes and some dismal failures, with the majority of installation somewhere between. Yet the simplicity, low capital and seemingly simple operation make this a circuit of choice for many.
autogenous grinding mills that are used in mines to finely crush ore material for mineral separation. A new and improved system was needed by a major manufacturer of grinding mills that was using the only inching drive available in the marketplace to facilitate selective rotation of mill cylinders at reduced speed for startup and maintenance work.
Autogenous mills are also known as AG mills which is an acronym for autogenous grinding mills. It is so-called due to the self-grinding of raw materials inside the grinding chamber: a rotating drum throws large-sized raw materials in a cascading motion which causes impact breakage of larger particles and compressive grinding of finer particles.
The two main character of an Autogenous Mill e.g. size reduction which occurs through the detachment of material from the surface of larger particles (referred to as 'abrasion') and the grinding ...

Autogenous grinding has two advantages, (1) it reduces metal wear and (2) eliminates secondary and tertiary crushing stages. Thus it offers a savings in capital and operating costs. Autogenous mills are available for both wet and dry grinding. The diameter of autogenous mills is normally two to three times the length.
An autogenous grinding mill may receive a coarse run of mine rock feed and discharge it as a finished ground sand or slime product. In order to efliciently break down the rock the mill must provide both impact and attrition forces. In mills with substantially smooth linings and operating at sub-critical or super-critical speeds the power ...

Since the early 1980s, we have been designing and manufacturing Semi Autogenous Mill (SAG Mill) and Autogenous Mill (AG Mill) under the Fuller-Traylor brand. 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 ...
a large effect on profitability. Mill operators have long used operating work indices to evaluate grinding circuit efficiency, with great utility. Operating work indices can be used to evaluate individual units in a conventional circuit or the overall performance of an autogenous-semiautogenous (AG-SAG)/ball mill circuit, but they are of

Every 24 hours, around 180,000 tonnes of ore are fed into the six milling lines' autogenous grinding mills (AG mills), these are the largest grinding mills in the world. Each mill measures about 12 metres in diameter and has an internal volume of 1,220 cubic metres. As the AG mill turns, the ore crushes against itself and breaks apart.
The AG mill (autogenous grinding mill) is a medium-free grinding machine. In order to improve the processing capacity, 2% -3% steel balls can be added (also known as semi autogenous grinding mill or SAG mill). Raw ore or coarse crushed ore from the mine can be directly fed into the AG mill (SAG mill) for grinding.
The feed material is lifted by the shell lining of the mill during rotation. Because of the gravity the material falls down and breaks as a result of the material impact. If the material is very hard or if the crushing is to be accelerated, grinding media can be added to the autogenous mill. In this case we speak of semi-autogenous mills.
Adoption of autogenous or semi-autogenous grinding (AG/SAG) would lead to a significant simplification alternative to such plants. Within the scope of AG/SAG grinding, several approaches can be used in size reduction. For instance, the mill may be operated in the absence of steel grinding media (AG) or with steel balls (SAG) (Gupta and Yan, 2016).
