The article presents the design of a pneumatic screw conveyor used to move (transport) grain materials. On the basis of this design, an experimental setup was created, enabling the performance of the new conveyor belt to be investigated in the laboratory, including the power parameters. The Altivar-71 frequency converter was used in experimental studies to determine the power parameters of the pneumatic screw conveyor for the transport of grain materials. Based on the results of the experimental studies, graphs of the power characteristics of the pneumatic screw conveyor drive over the time of the transport of grain materials were obtained. By analysing the graphs obtained, it is established that the smooth operation of the conveyor belt depends on the properties of the transported material. In particular, it affects the switching frequency of the pneumatic drive, which prevents it from overloading and, therefore, premature breakdown. In addition, activation of the pneumatic actuator destroys the resulting thickening of the transport granular material. Experimental studies have also been conducted on changes in performance Q of the pneumatic screw conveyor depending on the initial values of the high-pressure air supply P.
