The analysis of the existing pneumatic transportation systems is carried out, their advantages and disadvantages are noted, the purpose of the study was formulated. Calculation algorithm of main parameters of flow part of ring straight-flow ejector is developed. Influence of various factors on the ejector main characteristics is investigated. A prototype ejector was produced, and a number of experiments were carried out to verify the developed calculation method. The difference between the calculation and the experiment did not exceed 3%, which proves the accuracy of the calculation.
