The pitch on the screw conveyor flights are an important consideration. At full pitch, the spacing between the flights is equal to the diameter of the feeder. At half pitch, the spacing between the flights is …

The design of the screw is based on the theory of the inclined plane. The screw conveyor began to evolve in the late 1800s and was used as a means of increasing food and grain production to meet the needs of the rapidly growing American population. The first feed mills used screw conveyors throughout the process.

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 …
