Abstract in English: 

Background. Processes to separate bulk materials by grain size are widely used in the construction, chemical, mineral processing, and energy industries. The efficiency of the production process that uses the resulting powders often depends on the efficiency of the classification process. Therefore, improving the quality of finished powders based on modeling and improving their production technologies is a pressing issue.

Materials and methods. Modeling of classification processes in a separate stage and in a system of classifiers has been performed using a separation curve for a separate stage and the analyzed system of devices.

Results. A model has been developed for single-, dual-, and triple-row stage arrangements, with and without recirculation of non-target separation products. It has been shown that recirculation significantly improves the quality of the target products. Based on the obtained solutions, recommendations have been developed to improve the efficiency of bulk material separation processes in multi-stage classification systems.

Conclusions. The proposed algorithm and calculation method allow us to find optimal schemes and operating modes of classifying multi-stage installations.
