Screw conveyor design calculation an Engineering Guide

It is thus required in many projects to calculate the size of a screw conveyor in order to reach a required capacity. It can be also required to check the capacity of an existing screw in case the material handled change or the capacity required increases. Few formula exist in the literature and are presented in this short Engineering Guide.

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.

Sizing a Screw Conveyor

Jul 09, 2018 Most screw conveyor manufacturers call this the “diameter factor”. The basic HP calculation set for screw conveyors has three parts. The HP to convey the material, the HP to turn the screw, by itself, and the combination of these two for the total required HP.

Designing Inclined Screw Conveyors for Industrial

The capacity calculation for screw conveyors takes into account the outside diameter of the screw, the outside diameter of the center pipe, the pitch of the screw, and the trough loading. The calculation determines the capacity that will be conveyed with each revolution of screw rotation.
