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.

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 …

The first example of using an agitated vessel and grinding media for comminution was in 1922 when Szegvari stirred a gallon can full of pebbles to rapidly disperse a sulphur suspension [19].This was developed into the first 'stirred ball mill' by Klein and Szegvari in 1928 [20].This prototype was refined into the Attritor mill, a low tip speed (3–5 m/s [21]) …

If the 30–80 mm pebble generated during autogenous grinding is used as the medium to crush the ore, the process is called pebble grinding. The density of pebble is less than that of steel ball, and its friction coefficient and contact area with the ground ore are greater than those of steel ball, so pebble grinding process has strong grinding …
