Vertical conveying by Screw Conveyor, on the other hand, is quite successful and it remains that a 45° incline or angles approaching this figure, are the most difficult on which to achieve successful conveying. Additional power is needed to convey on an incline. This added power is a function of the power required to lift the material.
