AG Autogenous Grinding - Mineral Processing Metallurgy. 2019-11-25 In conventional milling, the ore is crushed to, plus or minus, 3/8 of an inch, before it is put into a mill for grinding. In a autogenous mill the ore is fed directly into the mill from either the primary crusher or the mine itself.
The mill power draw, throughput and product size distribution are used to compute a specific energy input and the MacPherson autogenous work index (AWI). Although the importance to achieve steady-state in a grinding test is widely accepted (Bond tests), the MacPherson test remains the only small-scale AG/SAG mill test that offers this option.

Rely on our proven track record of SAG and AG Mill superiority. Since the early 1980s, we have been designing and manufacturing Semi-Autogenous (SAG) and Autogenous (AG) Grinding Mills 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.
The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball 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.
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 Explained. Mill length was the primary variable investigated in an autogenous pilot mill circuit. The 5-½' diameter mill had both pebble ports and ½" wide slotted grates. The plus ½" mill product was crushed in a cone crusher and returned to the mill feed along with the minus ½" plus 4 or 6 mesh fraction.
Autogenous grinding or semi-autogenous grinding mills can be operated in open or closed circuit. However, even in open circuit, a coarse classifier such as a trommel attached to the mill, or a vibrating screen can be used. The oversize material is recycled either externally or internally.
