SIMULATION OF FRACTIONATION PROCESSES IN CYCLONE DEVICES

The article shows and studies the process of separating bulk materials in a centrifugal field, formulating the foundations for constructing its mathematical model. Based on the analysis of the processes occurring inside the cyclone apparatus, a hierarchical structure of the process has been compiled. A mathematical description of the determination of the rate of settling of fine particles, a mathematical description of the determination of the limiting particle size, and the determination of the number of particles deposited in the apparatus are obtained. A comparative analysis of the mathematical description of the determination of the limiting particle size with the mathematical descriptions in which is given in the literature data was carried out, on the basis of which an insignificant difference between them was established.
