### Energy-Efficient Technologies in Cement Grinding IntechOpen

Due to the more energy-efficient grinding process Cemex® ground cement will usually have a steeper particle-size distribution curve than corresponding ball mill cements. Consequently when ground to the same specific surface (Blaine) Cemex® cement will have lower residues on a 32 or 45 μm sieve and tend to have a faster strength development.
