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.

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.

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.

High-efficiency autogenous mill can realize the second and third stage crushing and screening, and part or all crushing and grinding of rod mill or ball mill. Low power consumption, no dust pollution, less auxiliary equipment, easy production automation, and stable particle size.
In this case, Xinhai efficient autogenous mill solved these problems effectively. Xinhai efficient autogenous mill can achieve two and three stage crushing, part or all crushing of ball mill and rod mill, it is suitable for the coarse grinding after coarse crushing.
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 mill. Autogenous or autogenic mills are so-called due to the self-grinding of the ore: a rotating drum throws larger rocks of ore in a cascading motion which causes impact breakage of larger rocks and compressive grinding of finer particles.
