Abstract：It is difficult to accurately detect the content of free calcium oxide in cement clinker in real time, thus a predictive model is proposed based on continuous deep belief network. Firstly, according to the cement clinker production process, the main variables in the firing system on the effect of the free calcium in the cement clinker are obtained. With the use of grey relational analysis theory, the grey relational degree is obtained, ignoring minor factors, and a set of auxiliary variables is established. Secondly, the cement clinker fCaO content model is built by using the particle swarm optimization algorithm to optimize the parameters of continuous deep belief network. Finally, compared with prediction effect of least squares support vector machine and back-propagation, the simulation results show that the model is of high precision and strong generalization ability.
