FEEDER-METERING DEVICE FOR BULK MATERIALS

摘要

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.1 dwg
