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 Simply put horsepower is a measure of the rate at which work is done In the case of the screw conveyor it is a measure of the power needed to move the material in question a defined distance and elevation Screw conveyor horsepower requirements are directly defined in the CEMA Standard No 350 Screw Conveyor for Bulk Materials To calculate the horsepower needs for a given application
