FIELD: transportation of loose materials.
SUBSTANCE: proposed feeder contains rectangular section confuser-diffuser housing with feed port in zone of mating of its confuser and diffuser parts. Charging funnel with control gate arranged in lower part of funnel is placed over feed port. Hosuing is connected by its confuser and diffuser parts with confuser and diffuser which are connected, accordingly, with air duct and material duct of plant. Louver grating is arranged in housing over its entire width under feed port in diffuser part, louver slats being tilted in direction of transportation of material. Turnable valve is installed for turning on end part of louver grating over entire width of housing.
EFFECT: reduced losses of air pressure for accelerating particles of material to be transported after its delivery into feeder, reduced specific power losses of pneumotransport plant.
