Autogenous grinding mills are similar but without the steel balls. The mills are fed and grind continuously. Their product is typically less than 0.01 m diameter. Autogenous and semi-autogenous mills are up to 10 m diameter with diameter-to-length ratios of 1.6:1–2.5:1.
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. Ore grinding is carried out in mills with a large diameter (up to 12 m) and short ...
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 …
In conventional mills the diameter of the mill is smaller than its length. In autogenous mills the diameter is greater than the length. They can be as much as 40+ feet in diameter. Patented in 1959, AG Mills are not so popular any more. This large diameter of mill is required to achieve the impact necessary to grind the ore.

The autogenous mill can process materials of any property, especially when grinding asbestos, iron ore, copper ore, limestone, gold ore, manganese ore, etc. It has a large grinding ratio, up to 4000-5000, and the feeding size is generally 300-400mm (910mm in special cases). After grinding, the material particle size can reach 0.1mm or less.
Uses cast iron rods as grinding medium Length is 1.5-2.5x the diameter Discharge types. Ball Mill!! Uses forged steel balls as grinding medium Length is 1-1.5x the diameter Autogenous / SAG Mills!!!! The action of the ore grinding upon itself …
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).
Semi-autogenous grinding mills. Semi-autogenous Outotec 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 ...

Autogenous 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 stages.
closed circuit operation in wet and dry modes. Conventional milling constraints and energy consumption issues are addressed while new dimensions are added to the feed size range acceptable for wet and dry grinding to fine and ultra-fine sizes.

The autogenous shrinkage and drying shrinkage can be regarded as water loss due to the self-desiccation or dry environment. The Japan Concrete Institute (JCI) referred to autogenous shrinkage as the macroscopic volume reduction of cementitious materials under sealed conditions after the initial setting ( Kovler and Zhutovsky, 2006 ).
Large-diameter autogenous and semi-autogenous grinding mills represent the primary thrust of the expanding grinding technology. In spite of initial difficulties, large autogenous and semiautogenous mills have reached an acceptable level of technology that provides the mineral engineer with a reliable, low cost means of ore comminution.A successful milling installation …
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 easily enabled in autogenous mills by attrition.
Classifier shaft seal rinsed by compressed gas to protect the bearings. Entirely autogenous grinding - no tool wear - no contamination. Warming of product prevented by grinding with cooled gas (20°C), therefore applicable for extremely temperature sensitive materials. Significantly lower compressor capacity as opposed to comparable jet mills.
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.
