### Screw conveyor design calculation - an Engineering Guide

The capacity of a screw conveyor with a standard screw flight can be estimated the following way : With. Q = screw capacity in kg/h. D = screw diameter in m. S = screw pitch in m. N = screw speed in rpm. α = loading ratio. ρ = material loose density in kg/m3. C = inclination correction factor.

Jan 09, 2008 Care should be taken to empty the conveyor before shut-down to avoid overload start-up conditions. Due to the fallback created in inclined screw conveyors by tumbling and agitation, the amount of material being pushed forward through the conveyor is reduced. To offset this loss of capacity, increased screw rotation is applied.
