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 intergrinding different materials, the softer materials tend to be ground finer. In air swept vertical mills, this can leave a higher quantity of the
