What is the difference between a SAG mill and ball mill?

The working principles of autogenous ball mill are: materials are fed in the first tube form the feeding end, where are wave-formed liners and steel balls. Steel balls are lifted by the force from the barrel and drop. Materials are ground by the impact of steel autogenous grinding machines and the force of the materials themselves.
