An energy based comparison of vertical roller mills

2015-3-10  The vertical roller mill equipped with an internal classifier is often said to be more energy efficient than tumbling mills working on the same material and the same size step (e.g. Gerold et al., 2012). It is long established in the cement industry and gains more and more importance in the industrial mineral and iron ore sectors.

Progress with Grinding Aids for Vertical Roller Mills

2021-3-26  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.
