Screw conveyor is a kind of continuous transportation equipment. It uses a rotating screw to transport the transported material along the fixed housing, which is like the nut stuck when the screw rotates and can only move transversely along the screw, and the force that causes the material not to rotate with the screw is the gravity of the material and the friction force on the housing.
The screw conveyor is relatively simple and the cost is low; Reliable work, simple maintenance and management; The size is compact, the section size is small, the occupation area is small; It can realize sealed transportation, which is beneficial to the transportation of materials that are easy to fly, hot and smelly, and can reduce the pollution to the environment. Easy to load and uninstall. The horizontal screw conveyor can be loaded and unloaded at any point on its transmission line;The unit energy consumption is large;The material is easy to grind and wear in the process of transportation, and the wear of spiral blade and material groove is also more serious
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 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.
