Screw Conveyor vs. Screw Feeder

Screw conveyor and screw feeders operate quite differently. A screw conveyor is control-fed by another piece of equipment, in most cases, another screw conveyor, belt conveyor or rotary air lock. Material flow into a screw conveyor is constant. A screw feeder is flood-loaded in the inlet area and meters material from a hopper, bin, or silo, providing a steady, controlled flow to downstream equipment.
