Capacity of Screw Conveyor: The capacity of a screw conveyor depends on the screw diameter, screw pitch, speed of the screw and the loading efficiency of the cross sectional area of the screw. Ground Screw Calculator. Screw Calculator. I would assume the motor is 80% efficient and the screw is 70% efficient for some reasonable ballpark estimates.

The helix angle of a drill bit is defined as the angle between the screw flight of a helix and any line perpendicular to the screw axis or pitch. Different helix angles on drill bits are suitable for different applications, for example, the drill bit with a high helix angle is more effective for cutting soft and long-chipping materials, as a ...

A 16-inch diameter screw conveyor will convey 2,496 cubic feet per hour at the maximum recommended speed of 80-rpm. The actual screw conveyor speed is calculated by dividing the Selection Capacity by the capacity at 1-rpm. …

I take the diameter of the center shaft, 1/2 the pitch and find the hyp length. then devide the hyp by 1.13. This will get you extreamly close. you can then multiply the desired diameter by the same (1.13) and you will have a concentric ring that should expand to meet your needs. I just built a couple using this formula and it worked great

P = pitch of the screw in inches K = percent trough loading It is the capacity over 1 rpm. If the dimensions are know, in the case of an existing screw, the screw capacity / h can then be found by multiplying by the rpm at which the screw is used. The formula gives similar results as the one stated above. 3.
