Ceramic Materials. Semiautogenous mill | BritannicaOther articles where Semiautogenous mill is discussed: mineral processing: Grinding: development is the autogenous or semiautogenous mill. Autogenous mills operate without grinding bodies; instead, the coarser part of the ore simply grinds itself and the smaller fractions. To semiautogenous mills (which have become widespread), 5 to 10 percent grinding bodies (usually metal spheres) are added.

Autogenous (AG) and Semi-Autogenous (SAG) milling has seen increased use in recent years especially in large mineral processing operations. These mills typically have a large diameter relative to their length typically in the ratio or 2 or 2.5 to 1. AG mills employ ore as the grinding media. Chat Online Autogenous GrindingAutogenous mills operate mechanically like ball mills; however, the media used for grinding differs. Simply put, in autogenous grinding, the media is also the material that is being ground, whereas in other milling methods steel or porcelain balls are used as media.
