Tapered Flight Screw Conveyors. In tapered flight screw conveyors, the pitch remains constant, and the flight width gradually increases from two-thirds of the screw diameter on the inlet side to full diameter on the discharge side. Tapered flight screw conveyors offer additional space for the fed material at the inlet to draw off material evenly.
