The Corrected Material Horsepower Factor, sometimes called the Overload Factor, is used to increase the Total Shaft Horsepower (TSHP) of a screw conveyor when the calculated Material Horsepower (MHP) is less than 5-HP. Increasing the TSHP allows the screw conveyor to overcome most upset conditions, reducing downtime and loss of production.

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.
