The Autogenous/Semiautogenous Grinding Mills are in most cases used as primary crushers. AG Crushers use the ore exclusively as their grinding media. In case the hardness and the abrasiveness of the Ore is not suitable enough to carry out the grinding process, steel balls are added inorder to assist the process; these are called SAG Crusher.

Crushing and grinding are the two primary comminution processes. Crushing is normally carried out on "runofmine" ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material. In comminution, the size reduction of particles is done by three types of forces: compression, impact and attrition.
