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.
