Feb 21 2017 · CEMA has developed standard pitches for screw conveyors full pitch short (2/3) pitch and half (1/2) pitch. Full pitch screws are typically used in horizontal screw conveyors because there is no loss in conveying efficiency. As a screw conveyor is inclined a full pitch screw will lose efficiency due to the angle of the flight. Pitch Efficiency
