Mar 13, 2020· The amount of water required can be reduced significantly by using appropriate grinding aids that stabilise the grinding bed without causing pre-hydration. Grinding of cement in a VRM can be 30-40% more efficient than in a ball mill and reducing the level of pre-hydration during VRM operation can potentially improve cement performance.
Progress with Grinding Aids for Vertical Roller Mills. The effect of grinding aids on the comminution of cement is based on the dispersion of fine particles. It is a misunderstanding that grinding aids for vertical roller mills (VRMs) should stabilise the material bed between the rollers and the table by adhesive forces between the particles.
