SikaGrind® for vertical roller mills

2021-7-9  The grinding of the finished cement consumes approximately one third of the total electrical energy of a cement plant. Vertical Roller Mills (VRM) have a clearly higher energy eciency 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
