Abstract

The article presents the developed experimental installation of a pneumatic screw conveyor and a research methodology for determining the power indicators that arise when moving bulk materials from the effects of air pressure and the volume of various types of bulk materials. Graphic dependences of the moving cargo effort on air pressure and the action of moving different bulk materials on their volume at constant air pressure are built. The dependences of the productivity of the pneumatic screw conveyor on the change in the area of the hopper opening, the rotational speed of the screw feeder and the value of the working air pressure in the technological line are established.
