FIELD: technological processes.
SUBSTANCE: invention relates to devices for supply of loose materials into apparatus and may be used in various industries, where it is required to supply loose material from one apparatus into another one, with availability of pressure difference between apparatuses. Device includes auger body, sealing chamber, cantilever screw of auger, plug from supplied material, rotary canopy for control of plug resistance and inlet nozzle of material receiving. At the end of cantilever screw of auger the last two-three turns of auger are arranged as double with gradual reduction of screw pitch down to 0.6-0.7 from the initial one.
EFFECT: increased reliability of device operation, maintenance of sealing plug from transported material, even delivery of material along auger section into sealing chamber.
