Energy consumption and output. Cement mills are normally driven by electric motors. Modern installations draw power of 2-10 MW. The power (in kW) required to turn a ball mill is approximated by: P = 0.285 d (1.073-j) m n where d is the internal diameter in metres, j is the fraction of the mill volume occupied by media, m is the total mass of media in the mill, in tonnes, and n is the mill ...
Cement Mill. The recommended cement mills in white cement production are vertical roller mills or ball mills. The use of these two mills is conducive to reducing iron pollution in the white cement production process. How Do We Improve Whiteness of White Cement.

Feb 16, 2015 For cement grinding, the technology development away from ball mills has taken a different route. The development of roller presses in the 1980s took advantage of the benefits of higher-pressure grinding and many presses were retrofitted to ball mills as pregrinders.
The immediate advantages of such mills can be easily summed up in the following key points: – vertical cement mills are able to reach production values which are significantly higher than the ones achievable with traditional ball mills. As the latter are able to reach an indicative maximum of 180 –200 t/h, vertical mills reach up to 300 t/h.
