On the basis of the obtained analytical dependences, the expediency of fan loading of bunkers with a powdery bulk material has been proved. The design of an annular loading device which reduces dust generation using the Coanda effect is proposed. The rational design and technological parameters of the developed device have been determined numerically and experimentally.
