A screw conveyor is made of a housing, typically a tube or a U trough, in which is rotating a screw flight or auger (helical shaped blade) that allows to mechanically move bulk materials. The screw can be shaftless, or having a shaft on which is welded the helical blade. Screw conveyors are a very popular equipment in solids processing industry
