2.1 General formula. 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.

Get PriceEmail contactA 16-inch diameter screw conveyor will convey 2,496 cubic feet per hour at the maximum recommended speed of 80-rpm. The actual screw conveyor speed is calculated by dividing the Selection Capacity by the capacity at 1-rpm. 1,873/31.2 = 60-rpm. 60-rpm is the correct speed for a 16-inch diameter screw conveyor with cut and folded flights and short pitch for conveying and mixing 333

Get PriceEmail contactCalculation of Conveyor Speed. Conveyor Speed can be most conveniently calculated, by use of the nomographs supplied on pages. To use this nomograph – first locate the two known values (screw diameter, and required capacity, in cu. ft. per hour), then with a straight edge connect these two points. The appropriate conveyor speed will be the intersection point on the third value column marked “Speed”.
