1. Screw conveyor design : methods How to size a screw feeder ? Screw conveyors are among the most widespread equipment for transporting and dosing bulk solids. It is thus required in many projects to calculate the size of a screw conveyor in order to reach a required capacity.
inclined screw conveyors typically operate from slightly above the horizontal position to 45-degrees from the horizontal position . above 45-degrees an inclined screw conveyor is considered a vertical screw conveyor and must be designed in accordance with the kwS Engineering Guide

Above 45-degrees an inclined screw conveyor is considered a vertical screw conveyor and must be designed in accordance with the KWS Engineering Guide for Vertical Screw Conveyors. As the degree of incline increases, conveying efficiency is reduced and horsepower requirements increase due to the effects of gravity and bulk material fall back.
The design of the screw is based on the theory of the inclined plane. The screw conveyor began to evolve in the late 1800s and was used as a means of increasing food and grain production to meet the needs of the rapidly growing American population. The first …

Calculate the driving power of a Drag Roller Chain Conveyor, commonly used in Sugar Plants considering the following sketch below: Where: Q - Chain conveyor capacity = 90 tph; δ - Sugar cane bulk density = 900 kg/m³ - (56 lb/ft³); v – Conveyor speed = 5 m/min (0.083 m/s) – (16.3 fpm);
Calculation of the nominal flow can be done once the screw geometry, its rotation speed and the filling coefficient are known. The flow rate of a screw conveyor or feeder depends on a number of interlinked factors: - geometry of the screw - rotation speed - inclination - geometry of the feed hopper and tube - flowability of the material.
For screw conveyor design purposes, conveyed materials are classified in accordance with the code system shown in Table A. This system conforms to that of the Conveyor Equipment Manufacturers Association (CEMA) which ranks each material in 5 categories. Table B lists the codes for many materials that can be effectively conveyed by a screw conveyor.
