Autogenous Grinding

Autogenous grinding is a process of grinding ore in a rotating cylinder, using large pieces of the same ore. Autogenous mills operate mechanically like ball mills; however, the media …

Crushing SAG Mill Critical Size Material

b) Semi autogenous grinding in which the pebble fraction of mill discharge (+½ in.) is taken out through pebble ports for separate crushing and ball milling. The minus ½ in. fraction of mill discharge is recycled to the SAG mill through a classifier. The circuit is called SACB: Semi autogenous/ Crusher/Ball mill.

Autogenous mill | Britannica

Other articles where autogenous mill is discussed: mineral processing: Grinding: 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 and Semi-Autogenous Mills

9.1. Introduction. Disintegration and size reduction of some ores is possible in tumbling mills without the aid of grinding media. Grinding mills in which comminution takes place without grinding aids are known as autogenous grinding (AG) mills or fully autogenous grinding (FAG) mills. These mills use large lumps of rock as the …

How it Works: Crushers, Grinding Mills and Pulverizers

Autogenous grinding (AG) and semi-autogenous grinding (SAG) mills use the material to be ground as the grinding media.
