Ball mills are a type of grinder used to grind and blend materials for use in various industries. The basic principle of ball mills involves two or more grinding media, such as balls or rods, rotating in a container to grind materials to a desired fineness. The principle of ball mills is based on impact and attrition.

SAG mill make use of steel balls included with some large and hard rocks for grinding. These mills utilize the balls in making the large fragments of materials broken into pieces. The ball charge of a SAG mill is about 9% to 20%.This process takes place inside the large rotating drum of SAG mill which is filled with balls partially.
