Inclined Screw Conveyors Stainless Screw Conveyor Design

The design is a bit involved and these items should be taken into consideration: More horsepower is required for Inclined Screw Conveyors: This is due to both lifting the product and “reconveying” product that falls back. Hangers should be eliminated: They create a “dead flow” area that is emphasized with inclined conveyors. This often

ENGINEERING GUIDE Screw Conveyors - Manufacturer

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. 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.

Inclined screw conveyor efficiency may also be detrimentally affected by the geometry of a standard U‐trough. A U‐trough design contains void space over the rotating screw resulting in material fallback during operation. This furthermore exasperates increased cross‐sectional loading and material

Screw Feeder Design for Metering Bulk Materials

Knowledge of the flow characteristics of bulk materials is extremely important for successful inclined screw feeder design. The angle of repose and flowability of a bulk material will determine the design of the screw feeder and the maximum angle of incline.

Inclined Screw Conveyors

A standard Screw Conveyor inclined 15 upward will carry 75% of its rated horizontal capacity. At an inclination of 25 a standard conveyor may only handle 50% of its horizontal capacity. These are estimated figures and will vary with the characteristic of the material being handled.
