FIELD: transport.
SUBSTANCE: this method is realised in material conveyance system, for example, that for conveyance of wastes including at least one wastes loading point 61 and transfer pipe (100) to be coupled with said loading point (61). Proposed device comprises separator (20) to separate conveyed material from carrier air and means (3) to develop pressure difference in pipe (100) during, at least, material conveyance. At least one portion of said pipe (100) can be used as a portion of the circuit. Conveyance air is forced by pump (3) during material conveyance. Pump suction side is connected with at least one separator (20) and, further, with outlet side of said pipe (100). Thus, at least the portion of conveyance air at pipe pressure side is forced into said circuit via pipe inlet (100). Conveyance air is circulated ay pipe section upstream of separator (20).
EFFECT: higher efficiency.
