Difference between a Cement Ball Mill and Vertical Cement Mill
Generally, a vertical cement mill is considered more energy-efficient than a cement ball mill. This is because the vertical mill consumes less energy per tonne of cement produced compared to the ball mill. Additionally, the vertical mill uses a higher percentage of grinding media in its grinding chamber, leading to a more efficient grinding ...
