>HOME>Power To Turn A Screw Conveyor

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.

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 it is first important

A 10-inch conveyor 35 feet long with a capacity of 10 tons per hour at 45 RPM has been selected. From the Materials Table, a Horsepower Factor of 0.8 is found for the material to be conveyed. The table also indicates Series 4 hanger bearings and shafts.
