Screw Conveying equipments are widely used in various industries, such as building materials, chemical industry, electric power, metallurgy, coal, grain and other industries. They are suitable for horizontal or inclined conveying of powdered, granular and small block materials, such as coal, ash, slag, cement, grain, etc., with material temperature less than 200°C. Screw conveyors are not suitable for conveying perishable, sticky and easy-to-cake materials. In concrete mixing plants, the role of screw conveyors is maximized.
(1) Screw conveyor is a kind of conveying equipment widely used in chemical, building materials, food and other sectors. It is mainly used to convey powder, granular and small block materials. It is not suitable for conveying perishable, sticky and easy to agglomerate materials.
(2) The ambient temperature for the screw conveyor is -20~50℃; the inclination angle of the conveyor β≤20°; the conveying length is generally less than 40m and the maximum length does not exceed 70m.
(3) Compared with other conveying equipment, screw conveyor has the advantages of simple structure, small cross-sectional size, good sealing performance, multiple loading and unloading points in the middle, safe and convenient operation, and low manufacturing cost. Its disadvantages are serious wear of machine parts, low conveying capacity, high power consumption, and easy breakage of materials during transportation.
