Vertical roller mill for cement grinding [13]. VRM shown in Figure1 uses hydraulically hardpressed conical shape 24 rollers against the horizontal revolving grinding table. To enhance comminution, the ... plant at different operating points uses local models.
The movement of the floating roller constitutes the basic principle of a roller press. The extent of the roller movement (roller gap) is a function of the pressing force generated by the hydraulic system in relation to the reaction forces exerted by the material being processed and the preset "zeroposition" of the roller .
applications of the vertical roller mill for cement grinding are less prevalent. The twocompartment ball mill operating in a closed circuit with a high efficiency separator is thus still the most preferred arrangement for new cement grinding installations although the vertical roller mill now has emerged as a viable alternative
