Improved SAG mills came in trend, which gives highly rated production. These mills are one of the most used and necessary equipment in grinding. Image Source: Working: 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%
