2002-5-30  I am in the process of setting up a screw conveyor with a diameter of 10inches, trough of 12 inches, 20 feet long, at an inclination of 35 degrees to the horizontal. The screw is required to convey Calcium in powder form with a bulk density of 80 Lb/cft (1000 Kg/cub.M). The screw speed is 20 RPM. I need help in figuring out what is the KW/HP of the motor required to drive the screw conveyor.

All About Screw Conveyors (Auger Conveyors) Types

2 天前  A screw conveyor (also known as an auger conveyor) is, unsurprisingly, the shape of a typical screw, albeit with some caveats. Firstly, the threads are exaggerated and the center may or may not be present (see Figure 1). However, they function almost identically to screws, where a drive motor turns the screw (also known as the auger), moving
