Particularly in the cement industry, ball mills have largely been replaced by roller mills for new plants [2], as they are compact, and the installation cost is smaller [3]. The vertical roller mills are up to 40% more energy efficient than ball mills [4]. The milled particles are typically a few microns to 100 μm in size.
