• Difference Between Sag Mill vs Ball Millmech4study

    Oct 12 2017 · Ball mill is a fine grinder. A horizontal or vertical rotating cylinder which is filled partially with the balls of ceramics small rocks and balls made from stainless steel. The ball charge of a SAG mill is about 29 to 30 . By friction and influence of tumbling balls inside rotating cylinder grinds the raw material to the required fineness.
