The aim of the study is to develop a method for calculating the number of revolutions of accelerated motion of a particle in a turbulent dust-gas flow in the field of centrifugal forces of the cyclone apparatus. The modeling of the process of pneumatic separation is carried out with various influencing parameters on the particle. On the basis of systems thinking, the technological structure of the process of concentrating bulk materials in the field of centrifugal forces is analyzed. The hierarchical structure of the system and the interconnected constituent elements have been determined. The examples show the curves of the dependence of the distance traveled by a particle with a size of 0.2 µm from the inner radius of 0.15 m to the outer 0.35 m of the cyclone device and the number of revolutions of the particle in the dust-gas flow. It was found that in the field of centrifugal forces the particle makes accelerating motion. It travels from the inner radius of 0.15 m to the outer 0.35 m in 0.21 seconds. During this time, it makes 0.3 turns inside the cyclone installation. Research results show a large share of accelerating motion of particles in cyclones. They will make it possible to calculate in a new way various apparatus for cycloning bulk materials.
