  • Glo Progress with Grinding Aids for Vertical Roller Mills

    for vertical roller mills (VRMs) should stabilise the material bed between the rollers and the table by adhesive forces between the particles. Grinding aids reduce the polarity of the cleaved surface and the attraction forces between particles. This means that agglomerates of fine particles and the packing of fine particles around a larger particle are dissipated, resulting in an improved ...
