OK™ cement mill The most energy efficient mill for cement

The OK mill efficiently grinds blended cements, with a wide range of additives such as slag, puzzolana, limestone and fly ash. Its versatility is demonstrated by the ability to switch between a wide variety of mixes, and to vary the particle size to meet individual needs. Particle size distribution

EnergyEfficient Technologies in Cement Grinding IntechOpen

Due to the more energyefficient grinding process, Cemex® ground cement will usually have a steeper particlesize 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.

Cement Kilns: Size Reduction and Grinding

Crushers are used to reduce material in lump form to a size sufficiently small to be fed to a mill for fine grinding. The cement industry processes requiring fine grinding are rawmix preparation, fuel preparation and grinding of clinker to make cement. All three may require a preliminary crushing stage.
