Calculate Horsepower For Inclined Screw Conveyors

Jan 09, 2008 · Screw conveyors can be used to convey bulk materials at an inclined angle, but several areas of design should be examined first. Because of the incline of the screw, several conveying problems begin to occur. 1. The horsepower per unit of material increases 2. The efficiency of moving the material forward decreases.
