Sprial screw conveyor is a kind of screw conveyor, which mainly uses the rotation of spiral shaft with spiral blade to make the material move relatively along the spiral surface, and the material is not rotated with the screw by the friction force of the material slot or the wall of the conveying pipe, so as to push the material axial and realize the transportation of the material.
U-type 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.
1. The structure is relatively simple and the cost is low;
2. Reliable work, simple maintenance and management;
3. The size is compact, the section size is small, the occupation area is small;
4. 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.
5. Easy to load and uninstall. The horizontal screw conveyor can be loaded and unloaded at any point on its transmission line;
6. The unit energy consumption is large;
7. 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.
