# Screw Conveyor Capacity

Screw conveyors can be operated with the flow of material inclined upward When space allows this is a very economical method of elevating and conveying As the angle of inclination increases the capacity of a given unit rapidly decreases The rotating part of the conveyor is sometimes called simply an auger

Since you have asked the questions using two mass units per time I am assuming you are trying to compute the rate of delivery of some number or volume of screws per unit of time to the end of the conveyor This simple computation could take sever

The actual capacity of the screw conveyor may be one-third to one-half of the theoretical capacity because of material characteristics screw-housing clearance and the degree of elevation Horsepower requirements for screw conveyors are difficult to determine because of the variations between different augers and materials

Conveyor capacity is determined by the belt speed width and the angle of the belt - and can be expressed as Q = ρ A v 1 where Q = conveyor capacity kg s lb s ρ = density of transported material kg m 3 lb ft 3 A = cross-sectional area of the bulk solid on the belt m 2 ft 2
