The horsepower calculations for screw feeders require additional considerations. Please consult KWS Engineering for screw feeder applications. 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

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.

It is thus required in many projects to calculate the size of a screw conveyor in order to reach a required capacity. It can be also required to check the capacity of an existing screw in case the material handled change or the capacity required increases. Few formula exist in the literature and are presented in this short Engineering Guide.

Level Ground Conveyors. Horsepower required for conveyors transporting material on level ground: 1 hp (English horse power) = 745.7 W = 0.746 kW; 1 ft (foot) = 0.3048 m = 12 in = 0.3333 yd; Lifting Conveyors. With lifting conveyors add lifting power from the chart below to the level ground power from the chart above.

Every calculation should contain a contingency factor to allow for occasional temporary overloads. It easy enough, given the low cost of low and fractional horsepower drives, to simply overpower your system. But your electrical controls contain a thermal overload which will trip the motor in the event of a jam or stall. This device not only protects the motor, it also protects from harm your

Screw conveyors transfer bulk materials volumetrically and capacity is calculated in cubic feet per hour. Screw conveyor capacity is affected when the flight pitch is reduced from standard full pitch. Reducing the flight pitch reduces the capacity. For example, a 1/2 pitch screw carries 1/2 the capacity of a full pitch screw at the same level of trough loading and speed. Capacity Factors for
