Application Range Of Screw Conveyor

- Oct 19, 2017-

Screw machine is widely used in various industries, such as building materials, chemical industry, electric power, metallurgy, coal mines, grain and other industries, applicable to the level or tilt conveying powdery, granular and small block materials, such as coal, ash, slag, cement, grain, etc., the material temperature is less than 200 ℃. Screw machine is not suitable for conveying perishable, viscous large, easily caking materials. In the concrete mixing station, the role of screw conveyor has been the most important embodiment [5].

(1) Screw conveyor is a kind of conveying equipment widely used in chemical industry, building materials, grain and other departments, mainly for conveying powdery, granular and small block materials. It is unsuitable for conveying perishable, viscous and caking materials.

(2) The ambient temperature used by the screw conveyor is-20~50℃, the inclination of the conveyor is β≤20°, the conveying length is generally less than 40m, the longest is not more than 70m.

(3) compared with other conveying equipment, the screw conveying has the advantages of simple structure, small cross-section size, good sealing performance, high intermediate loading and unloading, safe and convenient operation and low manufacturing cost. Its disadvantage is that the mechanical wear is more serious, lower transport capacity, power consumption and materials in the transport process is easy to be broken.
