• 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
