Modeling of the process of the cement separation in the closed aerodynamic unit

The process of energy capacity reduction and increasing of the productivity of the cement manufacturing technologies is closely related to the creation of the modern closed aerodynamic units (CAU) with recirculation, which allows achieving the effective separation of the high-dispersity materials. The purpose of this study is to simulate the cement separation process in a CAU consisting of separator, thickening agent and centrifugal collector. To achieve this goal, a methodology for calculating the probability interval of the final product granules in the main participants at all stages of the CAU operation is provided. The main conditions of the operating mode are established and the approach to solve the issues of the material separation under the conditions of the flow unit mode is proposed. Special attention is paid to the mathematical methods used to estimate the fractional emission of the small granules and calculation of the recirculated material. The studies include both analytical calculations and visualization obtained by means of charts of the granulometric composition of the final product for the various components of the unit. The obtained results represent the basis for the modeling and optimization of the cement separation process in the CAU, which ensures the reliable forecasting of the analytical materials and the further possibility of using of the new technologies.
