Grinding Balls For SAG_Goldpro. The ore in the SAG mill is mainly crushed by impact force, abrasive force and squeezing force between ore particles and grinding balls,through the continuous rotation of the mill, the large ore will be rotated into inner layer (near the center of the mill), and the smaller particles will be the outer layer.
The working principle of the self-grinding machine is basically the same as the ball mill, the biggest difference is that the sag grinding machine uses the crushed material inside the cylinder as the grinding medium, the material constantly impacts and grinding to …
Semi-autogenous grinding mills (SAG mills) are tumbling mills that most commonly have a shell diameter-to-length ratio of around two. With this high aspect ratio, SAG mills generate both thrown and cascading ball-milling actions with shell linings shaped to lift and to throw alloy steel grinding balls of up to 150 mm (6 in.) in diameter. These
