Screw conveyors capacity calculation

Screw Conveyor Ca.pa.city, The volumetric capacity of a horizoatal screw coaveyor is calculated oa the assumptioa that all material coataiaed within oae screw pitch moves oae pitch distance ia oae screw revolutioa. Volumetric coaveyiag capacity is calculated as... 

A screw conveyor transports seeds of 500 kg/m in bulk density and consumes 0.45 hp in power. Calculate the capacity, in tons/h, if the screw is 3.5 m long. 

Related Calculations. Use this procedure for screw or spiral conveyors and feeders handling any material that will flow. The usual screw or spiral conveyor is suitable for conveying materials for distances up to about 200 ft (60 m), although special designs can be built for greater distances. Conveyors of this type can be sloped upward to angles of 35° with the horizontal. However, the capacity of the conveyor decreases as the angle of inclination is increased. Thus the reduction in capacity at a 10° inclination is 10 percent over the horizontal capacity at 35° the reduction is 78 percent.
