Product Description
Inclined screw conveyors are used in many different applications in the process industry. These applications include agriculture, construction, and food and beverage industries. They transport raw materials such as cement, fertilizer, feed, sugar and meat. Since materials tend to fall due to gravity, they must be overcome. Inclined screw conveyors use trough covers and tubular casings to prevent materials from falling or overflowing. If necessary, the inclined screw conveyor can be stowed in a vertical position when not needed, thus saving storage space.
They are usually connected to vats, mixers, storage tanks, silos or ovens, and the most commonly used is to transport materials from a small container to a taller container. Due to the continuous rotation of the screw screw, the inclined screw conveyor may also perform some additional mixing or homogenization during transportation.When space allows, this is a very economical method of elevating and conveying. It is important to understand, however, that as the angle of inclination increases, the allowable capacity of a given unit rapidly decreases

Archimedes designed the screw conveyor in the third century B.C. The first screw was used for removing water from ships and for irrigating farmland. The original device consisted of spiral flights fixed to the inner wall of a hollow cylinder driven by a center shaft. As the assembly rotated, water was conveyed and lifted from one location to another. The spiral design is based on the theory of the inclined plane. The screw conveyor has evolved in modern times and is now used in almost every major industry. Today, thousands of processing plants throughout the United States and the world are using screw conveyors to convey bulk materials from A to Z (Adipic Acid to Zinc Concentrate).

The slope of an inclined screw conveyor determines the amount of material that it may hold at one time. As the angle increases and becomes steeper, the conveyor's capacity decreases. For example, a conveyor carrying material up a 15º angle is able to carry 75% of its horizontal capacity, while a conveyor operating at 25º holds only 50% of its horizontal capacity. Inclined conveyors should never have internal screw supports, as they obstruct the production flow.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. Inclined Screw Conveyor capacities can be increased over short distances, if no intermediate hangers are required.
Other aids in conveying on an incline are the use of shorter than standard pitch and/or tubular housings or shrouded conveyor trough covers. Very often it becomes necessary to use high speed to overcome the tendency of material to fall back.
The above aids are resorted to in order to overcome the tendency of a screw conveyor to become less efficient as the angle of incline increases. Vertical conveying by Screw Conveyor, on the other hand, is quite successful and it remains that a 45° incline or angles approaching this figure, are the most difficult on which to achieve successful conveying.
Additional power is needed to convey on an incline. This added power is a function of the power required to lift the material. Judgment and experience in the art of conveying are required.
Products can be conveyed and elevated at the same time by mounting a screw conveyor at an incline. This is often desirable because it covers two operations with one piece of equipment therefore saving space and reducing downtime, maintenance cost, etc.
A standard screw conveyor will often operate normally at angles up to 15º with only a small loss in capacity. Beyond that, adjustments and/or modifications are typically necessary.
