Ensuring the feed is spread thinly across the face of the roller mills can present some problems as mechanical feed gates can easily become obstructed, impairing the smooth and regular flow of product into the "nip" of the roller mill. Variability of raw material also needs regular adjustments as opposed to the allencompassing grinding nature of the hammermill.

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 ...
