The design of barbotage-rotation installation with different profiles of blades of the rotator has been created on the basis of modeling method. As a result of the complex of aerohydrodynamic research in the system "gas-liquid" carried out on the barbotage-rotation unit, certain recommendations on the improvement of the construction and operating conditions have been developed with a view to a rise in the effectiveness of dust removal.
