The screw conveyor is a kind of continuous conveying equipment without flexible traction, which uses the rotating screw to move the conveyed material along the fixed casing. It is as if the unrotatable nut is held and translated along the screw. The force that keeps the material from rotating with the screw is the gravity of the material and the friction against the shell.
The advantages of the screw conveyor are: simple structure, convenient maintenance, small size of the cross section, can enter and leave materials at any position in the length direction, and can use the cover of the tight closed housing to achieve a better sealing effect.
Therefore, screw conveyor is widely used in various industrial sectors to transport a variety of powdered, granular and small materials, such as coal ash, cement, sand, coal, cereals and so on; it is not easy to transport viscous caking materials which are easy to deteriorate.
U Trough screw conveyor is made up of screw part, bearing part and driving devices. Screw part is supported by both ends of bearing and middle bearing and driven by driving devices. When the screw conveyor operate, handling material will come into the feed chute by inlet, then do axial movement along the chute under the action of rotate screw until out of the outlet.
U Trough screw conveyor is bulk material handling equipment, it provides enclosed transfer while moving materials horizontally or at an angle,it can deliver materials from one or more inlet points to one or more discharge points. Screw conveyors can be operated with the flow of material inclined upward. When space allows, this is a very economical method of elevating and conveying. As the angle of inclination increases, the capacity of a given unit rapidly decreases.
U Trough screw conveyor is widely used in building materials, metallurgy, chemical industry, machinery, light industry, grain and food industry. U-type screw conveyor is suitable for conveying powder Shaped, granular, small bulk materials, such as cement, fly ash, grain, chemical fertilizer, mineral powder, sand, soda and so on. U-shaped screw conveyor is not suitable for transporting materials that are easy to deteriorate, sticky and easy to caking. The working environment temperature of the conveyor is usually-20 °40 °, the temperature of the conveying material is generally 20 °80 °℃, the U-shaped screw conveyor is suitable for horizontal and small inclination arrangement, and the inclination angle is not more than 15 degrees. If the tilt angle is too large, the tubular screw conveyor should be selected.
