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.
Mills that use intermediate size rock or pebbles as a grinding medium are also autogenous mills but are known as pebble mills. Mills that grind hard ores with fracture characteristics that do not lend themselves to fully autogenous milling are charged with a small amount of steel balls to assist in the size reduction.
