A special 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.

The MacPherson autogenous grindability test, as developed by Arthur MacPherson et al , is a continuous test performed in an 18" (46cm) semiautogenous mill, with an 8% ball charge. The test is run until a steadystate is achieved similar to the Bond rod mill and ball mill tests. A draft fan supplies the airflow required to remove the ground
Chapman et al. (2013) compared the effects of using different circuits HPGR (dry) rod mill (wet) and cone crusher (dry) rod mill (wet) on the flotation of base metal sulfides. They indicated that apart from the grinding environment, HPGR could produce finer particles than a cone crusher. This difference was higher in the fully dry system.
