Screw Feeder Horsepower Requirements The horsepower and torque requirements for a screw feeder are much higher than a comparable screw conveyor. A screw feeder must start up with a flood loaded inlet and the head load weight of the bulk material in the inlet section. Bulk materials also tend to pack when under pressure in a hopper, bin or silo.

Screw Feeder Design for Metering Bulk Materials ...

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.
