Many experts and scholars attribute the reason why the ball mill gradually "falls out of favor" to the fact that the grinding power consumption is higher than that of the vertical mill. The "ballless" has not yet been achieved because the grinding effect of the ball mill is more in line with the requirements of cement performance.
