Difference Between Sag Mill vs Ball Mill

 · 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.

Wet mill

SAG mills are also an optimum solution for wet grinding since crushing and screening in these cases can be difficult, if not impossible. Efficiency through automatic operation Outotec''s process engineers will assist you in creating an efficient software-driven process, from circuit design to start-up and optimization, to ensure you get your desired grinding results.
