Critical Speed of Ball Mill
Critical Speed of Ball Mill . For a ball mill, it does not have a constant critical speed, because of the centrifugalization of the steel balls is different according to different resistance and friction between ball loads.But the ball speed of centrifugalization is constant. When the critical speed of the ball mill also has a constant value, such as the grinding medium fill rate, liner type .
