productivity increase of vertical roller mill for cement grinding

  • Matthias Dietrich Sika Services AG

    Progress with grinding aids for VRMs T he 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. Grinding aids

  • Additives for cement

    allows for a shortened cement retention time in the mill which in the end leads to significant energy savings for each ton of cement produced. • Maintenance cost reduction Shortened cement retention time in the mill leads to a less intensive use of the grinding system therefore reducing mill maintenance cost per ton of cement.

  • Research of iron ore grinding in a vertical-roller-mill

    The total energy consumption for ore comminution will further increase within the next decades. One contribution to minimise the increase is to use more efficient comminution equipment. Vertical-roller-mills (VRM) are an energy-efficient alternative to conventional grinding technology. One reason is the dry in-bed grinding principle.
