The Autogenous Mill, also known as AG Mill, is a type of grinding mill used in the mining industry. This machine uses ore and rock itself as grinding media to perform its job. Unlike other types of mills that use steel balls or rods for grinding materials, the Autogenous Mill relies on the material being ground to break itself into smaller pieces.

There are many different types of grinding mills (Table 1). Some devices, such as ball mills, are more suitable for coarse materials. These mills use "large" media, ranging in size from 20 mm in diameter and up, to produce material from about ten microns to mesh sizes. Attrition mills are more appropriate for "mid-range" size particles.

This means that during one rotation of the sun wheel, the grinding jar rotates twice in the opposite direction. This speed ratio is very common for Planetary Ball Mills in general. Planetary ball mills with higher energy input and a speed ratio of 1:-2.5 or even 1:-3 are mainly used for mechanochemical applications.
