EXPERIMENTAL STUDIES OF THE PROCESS OF LOOSE MATERIAL TRANSPORTATION BY A PNEUMATIC-SCREW CONVEYOR

The article presents the developed design of the pneumatic-screw conveyor, as well as its experimental installation. The method of conducting experimental researches to determine force indicators at movement of different types of loose materials under the influence of air pressure and their volume of various types of bulk materials. Based on the conducted experimental studies, the response surfaces and two-dimensional cross-sections of the pneumatic-screw conveyor productivity when the material passes from the whole area in the hopper transition zone to the screw feeder, its rotation frequency and the working air pressure in the process line have been constructed.
