Screw conveyors are continuous working pieces of equipment for the transshipment of granular material with a screw ringed in by a casing. The calculation of the conveyor in relation to the efficiency and capacity is complex. The program enables it to compute several screw conveyors to come to optimum dimensions. The model used, is the model set forth by Rademacher.
It appears that maximum efficiency of a screw conveyor lies around 22%. The most important factor appears to be the coefficient of sliding friction between screw and granular mass.
