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.
For semi-autogenous grinding (SAG) mills, there are two basic forms of testing: single particle breakage and tumbling tests designed to recreate the actual mill environment. For high pressure grinding rolls and regrind mill sizing, a specific test designed for that piece of equipment is best.
Autogenous grinding (AG) and semi-autogenous grinding (SAG) mills use the material to be ground as the grinding media. Autogenous grinding mills use larger rocks to impact and break smaller rocks as the mill rotates. Semi-autogenous mills are basically the same autogenous mills, but with the addition of balls, similar to those in ball mills.

This can be used in conjunction with the Bond Rod and Ball Mill Work Indices to determine power requirements, and to suggest circuit configurations for autogenous grinding (AG) and semi-autogenous grinding (SAG) circuits.
Ball mill and autogenous mill are both common grinding equipment in mineral processing plant. The grinding equipment has large operation cost. The chosen of grinding equipment has large influence on mineral processing flow and construction investment. What are the differences and similarities between ball mill and autogenous mill? In this paragraph, we are going to .
design commercial grinding plants. The MacPherson Autogenous Grindability test is performed with a light ball charge (8%), so it is actually a SAG mill test, but the results from the test have been used for the analysis of both fully-autogenous (FAG) and semi-autogenous (SAG) circuits (the fine feed size to the mill
Autogenous Mills operate, mechanically, similar to the ball mill. They differ in the media they use to break or grind the ore.

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.
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.
