Blended Cement - an overview | ScienceDirect Topics
Choice of grinding mill. Presently VRMs are replacing tube mills for grinding slag and even clinker. Thus there are small differences in layouts of cement mills to allow for the use of VRMs and corresponding auxiliaries. The principal difference is the point of feeding fly ash in VRM systems. VRMs have built-in high-efficiency separators.
