The screw conveyor is a direct descendant of the Archimedes screw. However, while the Archimedes screw lifts fluids trapped within cavities formed by its inclined blades, the screw conveyor propels dry bulk materials (powders, pellets, flakes, crystals, granules, grains, etc.) through the pushing action of its rotating blades. Also, most screw conveyers in use today have a single blade, while modern Archimedes screws typically have two or three blades. | The screw conveyor is a direct descendant of the Archimedes screw.
