This research focuses on investigating the effects of the three different grinding aids, consisting of a mixture of amine, glycol and polyol in different ratios, on the model parameters of a twocompartment cement ball mill and an air classifier.
Cement mill is also called cement ball mill, which is mainly used for grinding cement clinker in the cement production process. It is one of the important cement equipment. The output of cement mill is 21~155 t/h, and the specific surface area of cement is 3300~3800 cm ² /g.
CHAENG cement ball mill equipment can reduce energy consumption by 30% and increase the processing amount by 1520% after transformation. The cement ball mill can perform dry process production and also wet process production, moreover it can do grinding and drying at the same time.
A TakagiSugeno model with unmeasurable premise variables is developed for a nonlinear model of a cement mill. Based on this model, a nonlinear observer is proposed in order to estimate the state variables and also the clinker hardness, which is an unknown input of the process.

Motivated by the above observations, this paper focused on the formulation of a predictive model for determination of particulate dispersion from a cement mill stack. Several model equations have been developed for determining the concentration of air pollutants, most importantly is the Gaussian Dispersion model.
Calculation of the power draw of dry multicompartment ball mills 225 The mill load that is the volume of charge in the mill is the principal determinant of power draw. Estimation of the ball load that is mixed with the cement charge is difficult and can be highly erroneous. So direct measurement must be taken for calculation of mill load.
properties of this model will be validated and parameters estimated, against plant data or a more sophisticated simulation model. Ultimately this work aims at the development of a MPC strategy for control of cement mill circuits. In the following section a brief introduction to the system is provided and section 3 gives the model
