ABSTRACT:
A screw feeder for particulate solids comprises a trough section including a first chamber with a trough shaped side wall downwardly converging to a longitudinally tapered aperture. A screw chamber encloses a space below and connecting with the aperture. The screw chamber houses a feed screw which enters a feeder section in a transition region at the front wall of the agitator chamber. An agitator draws material away from the transition region of the agitator chamber.
