The difference between ball mill and vertical mill in cement grinding Over the last three decades the vertical roller mill has become the preferred ball mill for grinding of raw materials. The grinding efficiency of the vertical roller mill combined with an ability to dry, grind and classify within a single unit gives the vertical roller mill a decided advantage over a ball mill system.
Vertical roller mills can have lower power than ball mills in most applications for dry grinding. One comment that I did not see here is the potential for differential grinding, especially in vertical mills, but also in ball mills. That is when inter-grinding different materials, the softer materials tend to be ground finer.
The mill produces optimum-quality, high-resistance cement with a lower Blaine, and enables an exceptionally high cement/clinker ratio. The FCB Horomill® helps cement producers reach sustainability goals through: The lowest energy consumption on the market (30-65% energy savings compared to ball mills, and 10-20% compared to vertical roller mills)
