Designing Inclined Screw Conveyors for Industrial ...

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
