Types of Screw Conveyors Engineering Guide

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 for Vertical Screw Conveyors.

DESIGN CONSIDERATIONS AND PERFORMANCE

Screw conveyors may be grouped, broadly, into two categories, the U-shaped trough type conveyor and the fully enclosed conveyor incorporating a tubular casing. Screw conveyors with U-shaped trough type casings are widely used in industry, their operation being restricted to low angles of elevation, low speeds and low fill ratios.

Screw Conveyor - an overview ScienceDirect Topics

9.15.1 Screw Conveyors. Screw conveyors are used to convey bulk material from almost any position (vertical, horizontal, or at an incline) and are one of the most reliable methods of conveyance. The screw conveyor is composed of a pipe with a welded steel strip that is formed into a continuous helix. The helix is referred to as the flighting.
