Comparison between grinding of cement clinker with and without grinding aid (after Fuerstenau, 1990) Figure 1 shows the typical comparison between grinding of cement clinker with and without a grinding aid in a laboratory mill. As discussed in the literature [1,2,4], there was significant effect of using grinding aid in cement grinding.
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.

Grinding systems are either 'open circuit' or 'closed circuit.' In an open circuit system, the feed rate of incoming clinker is adjusted to achieve the desired fineness of the product. In a closed circuit system, coarse particles are separated from the finer product and returned for further grinding.
