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. WebThe screw conveyor conical auger flight centres provide a continuous incremental change in swept volume of the screw. This promotes even drawdown in a full hopper situation. Combined with variable pitch the coned screw provides the best possible solution to even hopper drawdown. Standard troughs can be used with coned flights.
