In the era of limiting the use of primary raw materials in production technologies, it is becoming necessary to reuse secondary raw materials (closed-loop economy). These raw materials very often consist of a large number of various physically and chemically homogeneous substances, but their reuse requires a prior purification process to remove undesirable components (raw material enrichment). A pneumatic classification process can be employed for this purpose. The paper presents the possibility of modeling complex classification processes. For this purpose, the basic laws of dynamics of dispersed systems were used. Mathematical programming methods were applied to identify the presented model. The identification of the model was carried out using the results of experimental studies on the separation of a mixture of different components in a two-stage classification system. The presented experimental results and the computational model can be used to formulate and solve optimization problems of fractionation of dispersion materials and to increase the efficiency of the process in classification systems.
