Flight vs pitch screw
WebA screw conveyor or auger conveyor both use a rotating helical screw blade, called “flighting”, usually within a tube, to move liquid or granular materials. There are several types of auger flights: helicoid, sectional, ribbon, and shaftless auger flighting. The two main types used in production are helicoid and sectional. WebInclined screw feeders are typically designed with multiple flight pitch changes. Shorter flight pitches are used in the inlet section to control the capacity or feed rate. Typically, the flight pitch increases beyond the …
