Screw Conveyor Overview (Screw Feeder / Auger)

A screw conveyor is made of a housing, typically a tube or a U trough, in which is rotating a screw flight or auger (helical shaped blade) that allows to mechanically move bulk materials. The screw can be shaftless, or having a shaft on which is welded the helical blade. Screw conveyors are a very popular equipment in solids processing industrySpreadsheet for Calculation of Screw Conveyor. Spreadsheet for Calculation of Screw Conveyors (Conveyor threads).

Screw Conveyor Engineering Guide Horsepower Calculation

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.It must be noted that those formula aim at giving an idea of the size of the screw conveyor (which means its diameter) and the speed at which it will operate, based on some assumptions and some design decisions (choice of screw pitch, inclination). The formula can also be used to roughly check the capacity of an existing screw conveyor power Screw Conveyor Power Calculation BlogMech

Determination of the optimal working performance matching

An experiment was conducted to investigate the effect of screw speed, feeding head speed, and the nature and type of granular material on the productivity and power consumption of a screw conveyor, and then determine the optimal speed. This experiment contains two parts. Part one was designed with 11 levels of screw speed A 12-inch diameter screw conveyor was selected for the example. The minimum standard shaft size for a 12-inch diameter screw conveyor is 2-inch diameter. The corresponding pipe size is 2-1/2-inch schedule 40 pipe with 5/8-inch diameter coupling bolts. The materials of construction of the screw conveyor is carbon steel.Screw Conveyor Example Engineering Guide KWS
