Abstract: Invention refers to the pneumatic transport field, namely to vacuum-pneumatic transportation of bulk materials of high mass concentrations through the long-distance pipelines. The invention can be used in various fields of technology, particularly when it is necessary to carry out the technological processes and transportation processes simultaneously. The device comprises at the inlet the suction pipeline with bulk material input part having vertical and horizontal sections connected to bulk material discharger. Bulk material discharger is provided with the sluice gate and vacuum gauge and connected to vacuum pump. This connection is realized through two or more vacuum receivers, interconnected in parallel by air ducts with high-speed valves so that on the one side of the receivers the air ducts are connected to suction pipe of vacuum pump, and on the other side of the receivers the air ducts are connected to the discharger.
