Screw conveyors become less efficient when they are used to convey material vertically. Capacity decreases with inclination about 30% for a 15° inclination and about 55% for a 25° inclination. Tube and U-trough screw conveyors are the two most common conveyors of grain. Generally, U-trough screw conveyors operate at a lower speed than tube screw conveyors.
