Modeling of energy consumption factors for an industrial cement
This can be counted yearly as over 6% of global energy consumption. More than 60% of this tremendous energy has been used in the comminution units (crushers and mills) to reduce the size of raw materials and clinker 1 – 3. In the mid-1990s, the vertical roller mill (VRM) was introduced to the cement industry to reduce this energy usage.

Progress with grinding aids for VRMs
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. Grinding aids reduce the polarity of the cleaved surface ...
