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. It is very important to design a screw conveyor with sufficient horsepower in order to prevent downtime and loss of production.
