An extruder such as a reclaim extruder includes a feed section with a throat into which a force feeder is positioned to compact and feed reclaim material at a higher and more productive rate. The force feeder includes three side-by-side augers pointed at the extruder screw axis. An AC variable frequency drive motor drives a double sided cog belt in serpentine fashion around respective pulleys or sheaves for the augers. Two of the augers are of one hand rotated in one direction, and one of opposite hand rotated in the opposite direction. The pulleys or sheaves are of different size so that each auger rotates progressively faster moving down stream of the extruder screw. Each auger is positioned in a closely fitting compression tube each provided with an inlet opening. The force feeder is conveniently angularly positioned through the wall of a collection box between a hopper and the throat of the extruder.
