depending upon the bulk material and the objective proper design and construction of an inclined screw conveyor will provide many years of uninterrupted service and productivity. the purpose of this article is to help the reader understand the basics of inclined screw conveyor design for various applications. history of screw conveyors
inclined screw conveyors are used to convey and elevate bulk materials from one level to another. depending upon the bulk material and the objective proper design and construction of an inclined screw conveyor will provide many years of uninterrupted service and productivity.
design of inclined screw conveyor. below an inclination angle of 15 degrees the screw conveyor operates like a normal horizontal conveyor with minimal losses in capacity. the design of an inclined screw conveyor system requires: more horsepower for lifting product and “ reconveying ” product that falls back
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
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.
