Portland Cement Clinker - an overview | ScienceDirect Topics

Portland cement clinker is a hydraulic material which shall consist of at least two-thirds by mass of calcium silicates (3CaO.SiO 2 and 2CaO.SiO 2), the remainder consisting of aluminium and iron containing clinker phases and other compounds.The ratio of CaO to SiO 2 shall not be less than 2.0. The magnesium oxide content (MgO) shall not exceed 5.0% by mass.

Modelling and Simulation of Air Classification in Cement ...

In cement manufacturing, the finish grinding circuit consumes more energy from the raw grinding circuit. Thus, it is necessary for the system to have an efficient air classifier in order to reduce the energy consumption of the cement production. A mathematical model was developed for describing the air classification in the air classifier, in the finish grinding circuit.
