A screw conveyor with U-trough and 2/3-pitch screw is sufficient for most applications. Loss in efficiency can also be overcome by increasing the speed or the diameter of the screw conveyor. Additional horsepower is required to overcome gravity and bulk material fall back.

Screw Conveyor Basic Conveyor Flight and Pitch Types ...

Standard pitch, single flight screws have the outside diameter equal to the pitch and are the most common screw type used for horizontal screw conveyors and inclines up to 10-degrees.

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
