The amount of water required can be reduced significantly by using appropriate grinding aids that stabilize the grinding bed without causing prehydration. Grinding of cement in a VRM can be 3040% more efficient than in a ball mill and reducing the level of prehydration during VRM operation can potentially improve cement performance.
