Screw Feeder Design for Metering Bulk Materials ...

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.

Inclined Screw Conveyors

Vertical conveying by Screw Conveyor, on the other hand, is quite successful and it remains that a 45° incline or angles approaching this figure, are the most difficult on which to achieve successful conveying. Additional power is needed to convey on an incline. This added power is a function of the power required to lift the material.

Most screw conveyors manufactured today range in size from 4 to 24 inches diameter. The maximum allowable load of bulk material in a convey is 45% of the screw diameter. A 12 inch diameter screw conveyor filled to 45% can move 1,000 cubic feet of material per hour. Screw conveyors should not be filled above 45%.
