### How to Size a Screw Conveyor > Screw Conveyor Parts

To ease the calculation, most screw conveyors are full pitch, meaning the distance from flight to flight is the same as the diameter, and are running at 30%-45% trough fill level. Trough fill level is the percentage of available cross sectional area of the screw diameter. Why 30%-45% trough loading? The answer is the material needs some room to move around as it is conveyed and more ...
