1 Introduction Although the overall number of mills sold world-wide to the cement industry has been decreasing since 2011, the number of sold vertical roller mills (VRM) has increased. This is the result of a new market study by OneStone Consulting [1]. The mill data for the period 2010 to 2012 are presented in Fig. 1 .
Vertical cement mills are able to reach production values which are significantly higher than the ones achievable with traditional ball mills, in some cases up to 300 t/h. Empirically, It can be estimated through a simple heat balance that in ball mills only 10% of the energy is used to

Vertical roller mills. An investigation on vertical roller mills (VRMs), which use comparatively larger rollers instead of grinding balls as grinding tools, was carried out by Pohl et al. . In VRMs, the feed material is stressed as relatively thick particle beds between a roller and a rotating plate by means of high shear and compressive forces.
Earlier research results show that when the specific surface area of grinding is greater than 400 m 2 /kg, as the grinding fineness increases, the rate of decrease in the output of the vertical mill is the smaller. With the improvement of grinding fineness, the energy-saving advantages of vertical mills will be more significant.
