Screw conveyor design calculation - an Engineering Guide

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.

Total Shaft H.P. Calculation. TSHP = FHP + MHP* *Corrected if below 5 HP. Note: The actual motor horsepower required to drive the loaded conveyor system is dependent on the method used to reduce the speed the motor to the required speed of the conveyor. Drive losses must be taken into consideration when selecting the motor and drive equipment.
