Spiral Flighting Supplies
Basic Pitch Type Available
Standard Pitch, Single Flight
Conveyor screws with pitch equal to screw diameter are considered standard. They are suitable for a wide range of materials in most conventional applications.
Short Pitch, Single Flight
Flight pitch is reduced to 2/3 diameter. Recommended for inclined or vertical applications. Used in screw feeders. Shorter pitch retards flushing of materials which fluidise.
Standard Pitch, Double Start Flight
Double flight, standard pitch screws provide smooth, regular material flow and uniform movement of certain types of materials.
Long Pitch, Single Flight
Pitch is equal to 1 1/2 diameters. Useful for agitating fluid materials or for a rapid movement of very free-flowing materials.
