### Design Of Screw Conveyor Size Of Screw Conveyor Screw

The capacity of a screw conveyor depends on the screw diameter, screw pitch, speed of the screw and the loading efficiency of the cross sectional area of the screw. The capacity of a screw conveyor with a continuous screw: Q = V. ρ Q = 60. (π/4).D2.S.n.ψ.ρ.C

### Screw Conveyor Corporation

The initial step in engineering a Screw Conveyor is to analyze the physical characteristics of the material and the rate at which it is to be handled. The capacity of a Screw Conveyor should be defined in terms of cubic feet per hour. It is also important to deter-mine the maximum capacity the conveyor will be required to handle.
