The sequence to evaluate the vertical roller mills consisted of a laboratory jaw crusher, a rod mill and two ball mill stages with differing grinding media. The dimensions and settings of the laboratory mills are given in Table 1 and are illustrated in details in ( Boehm and Flachberger, 2006 ).
Operating a ball mill is quite simple as it lacks any moving mechanical parts within the mill. The system is quite versatile and is designed to accommodate variation in mill feed quantity and quality. On the other hand, the vertical roller mills (VRM) is quite a complicated and sophisticated equipment with hydraulics that controls the rollers.

At present, there is a tendency to be replaced by vertical mills, roller presses, etc., but the ball mill has a "granular shape that is approximately spherical, which is conducive to raw material calcination and cement hydration hardening". The special advantage is that this is the main reason why clinker mills still use ball mills. 2.
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. However, despite these benefits, applications of the vertical roller mill for cement grinding are less prevalent.
