The pitch on the screw conveyor flights are an important consideration. At full pitch, the spacing between the flights is equal to the diameter of the feeder. At half pitch, the spacing between the flights is half of the diameter of the feeder. If the pitch across the flights is the same, pressure will build up towards the end of the conveyor.
