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.

SAG Mills – Mining Technology | TechnoMine. SAG is an acronym for Semi-Autogenous Grinding, which means that it utilizes steel balls in addition to large rocks for grinding.

Grinding action is by particle-on-particle impact (AG Mills) and a combination of ball & particle-on-particle impact (SAG Mills). SAG applications include both wet and dry operation. The discharge of the AG/SAG mill is fitted with a grate discharge, where ground material passes through slotted apertures into a pulp chamber that then lifts the ...

SAG Ball consumption is "average" at 400 g/t while Ball Mill grinding media (3″ balls) usage in 550 g/t. Yet, you add steel and nothing seems to happen, tonnage is not noticeably improved. You need more tonnage and could actually use a larger/coarser transfer size from the SAG to Ball Mill.
