Screw conveyor design calculation - an Engineering Guide
No specific duty for the screw, the pitch is chosen standard, S=0.1 m Sugar is free flowing, a loading of 0.45 is selected The screw is installed without inclination, C=1 Sugar density is 800 kg/m3 The calculation gives 17 kg/h for 1 rpm. Adjusting the speed, 207 rpm are required to reach a capacity of 3500 kg/h.

Thus TSHP is calculated as follows: TSHP = 0.256 + 1.320 = 1.576 H.P. Assuming a drive efficiency of 85% resulting in a total drive horsepower of 1.853, a standard 2 horsepower motor would be selected for the drive input. The horsepower required for the above conveyor may also be determined graphically by the use of the two horsepower nomographs.

Screw Conveyors CEMA 350) can be useful for calculating the power requirement for a screw conveyor, but provide less information for a screw feeder. In the literature only a few papers have discussed the power required for a single screw feeder; discussion of the power requirement for twin screw feeders has not been seen.

DESIGN AND SIZING OF SCREW FEEDERS - TUM
Calculation of the nominal flow can be done once the screw geometry, its rotation speed and the filling coefficient are known. The flow rate of a screw conveyor or feeder depends on a number of interlinked factors: - geometry of the screw - rotation speed - inclination - geometry of the feed hopper and tube - flowability of the material.
