Vertical Roller Mills (VRM) have a clearly higher energy efficiency than ball mills, even if the ball mill is combined with a roller press. This and further arguments led to the increased share of VRM for the grinding of finished cement. Taking into account that VRM usually have a bigger output than ball mills, it can be declared that the major part of the cement production with newly ...

A vertical roller mill has a rotatable grinding table (1) which is fed with material to be ground through a feed pipe (14) so that a cone of material is formed between the bottom of the pipe and the table, and scrapers (25) for intercepting the cone and spreading the material over the table and under grinding rollers. In order to avoid the feed pipe running empty so that the cone is not formed ...
