Grinding Mill an overview ScienceDirect Topics
Autogenous mills (AG) pulverize due to self-grinding of the ore without any additional breaking media. The drum is typically of large diameter with respect to its length, generally, in the ratio of 2 or 2.5 to 1. The rotating drum throws larger ore particles in a cascading motion which causes impact breakage of larger and compressive grinding of finer size. It operates at a lower cost. The AG
