Milling Machine: What is a Autogenous Mill? - Quora
An autogenous (AG) mill is a grinding mill used in the minerals processing industry. It is shaped like a huge drum on its side and spins rapidly to carry ore to the top using centrifugal force. Gravity assists in smashing ore against other ore to pulverise rock to a size small enough to seperate minerals from gange.

Autogenous mills are also known as AG mills which is an acronym for autogenous grinding mills. It is so-called due to the self-grinding of raw materials inside the grinding chamber: a rotating drum throws large-sized raw materials in a cascading motion which causes impact breakage of larger particles and compressive grinding of finer particles.
