The feed material is lifted by the shell lining of the mill during rotation. Because of the gravity the material falls down and breaks as a result of the material impact. If the material is very hard or if the crushing is to be accelerated, grinding media can be added to the autogenous mill. In this case we speak of semi-autogenous mills.
