View AllBall mill When the particle size of the product is less than 0 5mm the grinding effect of the ball mill is greater than that of a rod mill of the same specification SAG mill The SAG mill has a wide range of feeding particle sizes and can process larger minerals but at the same time its output particle size is relatively larger
View AllThe operating principle of the ball mill consists of following steps In a continuously operating ball mill feed material fed through the central hole one of the caps into the drum and moves therealong being exposed by grinding media The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls Then discharge of ground material
View AllEven the SAG ball charge needs to be adjusted based on the size and hardness of ore it’s working on Too many grinding balls can prematurely wear out the grinding balls themselves Operating a mine mill requires balancing a dynamic set of tradeoffs
