Abstract

The paper presents the developed design of a research prototype of a pneumatic screw conveyor and the research methodology aimed at determining power characteristics for moving various types of loose materials depending on the influence of pressure and air volume. The dependences of pneumatic screw conveyor efficiency on the change in the area of a hopper hole, the rotation frequency of a screw feeder and the value of an operating air pressure in a technological line have been determined. The influence of the form and the geometrical parameters of a central replaceable nozzle on the distance of loose materials transportation has been determined.
