  • What's the Difference Between SAG Mill and Ball Mill

    The working principle of the selfgrinding 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 gradually pulverize Sometimes, in order to improve the processing capacity of the mill, a small amount of steel balls be added appropriately, usually occupying 23% of the volume of the mill (that is semiautogenous grinding)

  • Grinding Mineral Processing

    The grinding circuit usually consists of a SAG or AG mill and one or two ball mills Grinding is continuous and fully integrated with subsequent flotation operations SAG or AG mills The crushed products are ground in SAG or AG mills The selfgrinding machine can grind ore without grinding media such as iron ball, or steel rod, as long as the hardness of the ore is sufficient for the rolling ore to grind
