The installation of grinding plants for the milling of cement and blastfurnace slag has rapidly increased in recent decades. With this shift in investment, there has been greater demand for flexible and compact grinding systems, ideally near raw material sources and often in remote areas. By Caroline Woywadt, Gebr Pfeiffer, Germany.
For decades vertical roller mills (VRMs)have been in use in the cement industry for the grinding of raw material and coal. Since the 1980s VRMs have also been used for the combined or separate grinding of clinker and additives. Over the last three decades, the number of cement and blastfurnace slag grinding installations has increased remarkably.
