FIELD: machine building.
SUBSTANCE: feeder-metering device for bulk materials provides for the supply of bulk materials to the working zone with minimal wear of screw and bearing units due to a removable antifriction insert protecting the casing against the impact of the materials, a screw groove made in the shaft friction zone and a compactor with coiling directed to the side being the same as the screw coiling direction, due to which the material is removed from the bearing to the screw unit side.
EFFECT: invention allows for the regulation of material supply to the working zone, increased operation life of screw and bearing units.
