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 mid1990s, the vertical roller mill (VRM) was introduced to the cement industry to reduce this energy usage.
