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.

A conveyor belt works by using two motorized pulleys that loop over a long stretch of thick, durable material. When motors in the pulleys operate at the same speed and spin in the same direction, the belt moves between the two.
