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.
Xoptix Coal
The need for real time particle size measurement of coal. Optimization of the milling of pulverized fuel plays an essential part in reducing NOx emissions and the milling costs associated with grinding the coal to the optimum size. Traditionally coal was mainly supplied from local pits to power stations in the vicinity.
