FIELD: transport.
SUBSTANCE: invention relates to device and method for receiving and transferring fine to coarse substances from bin to high pressure system through locking element when granular material compression is forbidden, when reliable transportation of solid substances is also provided in case of heavy granular substances as well as high versatility when using various granular substances during operation and as great as possible mass flow to receiving bin. In device inside the bin (1') at distance in direction (g) of gravity action, over the locking element (18), following is provided: at least one vertically oriented, opened at top and at bottom central tubular body (2) - central tube, as well as delivering gas to bin bottom (19) and/or central tube (2) devices (4, 7) for gas delivery to form solid substance flow in the central tube.
EFFECT: invention provides reliable transportation of solid substances including heavy granular substances in large mass current without their compression.
