  • Difference Between Sag Mill vs Ball Mill mech4study

    Oct 12, 2017· In ancient time, the mills were operated with muscle power (by hands), water animals and wind. They were totally based on the mechanical energy by natural resources and living are many types of mills which are used in the grinding industries. Today we will discuss about two important mill, sag mill and ball mill.

  • What's the difference of Ball mill, SAG mill, AG mill?

    The impact can be rock on rock such as in an Autogenous Grinding (AG) mill, rock and a small ball charge (~10%), used in Semi Autogenous Grinding (SAG) mills, balls of various sizes in Ball Mills and less commonly these days, steel rods in Rod Mills. These machines are used to grind or mix metals or raw materials for further processing.
