Screw Conveyor Horsepower | Engineering Guide
Horsepower is defined as the power required to safely and feasibly convey a bulk material a fixed distance in a screw conveyor. The horsepower required to drive a screw conveyor is called Total Shaft Horsepower, or TSHP. TSHP is a function of the characteristics of the bulk material being conveyed and the friction inherent in the screw conveyor ...

Screw Conveyors
Ribbon conveyors are a modification of the helicoid and are used on sticky materials where the solid flights will not clear themselves. These are rated at about 75 % of the capacity of solid screws. Paddle conveyor screws are used where more than one material is carried and it is desired to mix the feed. The angle of the paddle can be varied.
