- Difference Between Sag Mill vs Ball Mill - .

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 beings.There 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.

- Ball mill - Wikipedia

A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotati
