critical speed of ball mill theory

Critical Speed of Ball Mill Source: clirik By Administrator Posted: . 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.
