    These consist of a pair of rollers set 8–30 mm apart and counter-rotating with surface speed around 0.9 - 1.8 m.s . The bearings of the rollers are designed to deliver a pressure of 50 MPa or more. The bed of material drawn between the rollers emerges as a slab-like agglomeration of highly fractured particles. The energy efficiency of this process is comparatively high. Systems have been designed, including a de-agglomerator and separator, that will deliver material of cement fineness. However, particle size distrib

  • Energy-Efficient Technologies in Cement Grinding

    23/10/2015  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. When grinding to a 28-day-strength target ...
