From the perspective of the displacement direction of conveying materials, screw conveyors are divided into two types: horizontal screw conveyors and vertical screw conveyors. They are mainly used for horizontal conveying of various powder, granular and small pieces of loose materials. And vertical lifting, this machine is not suitable for conveying special materials that are easily deteriorated, viscous, easy to agglomerate or high temperature, afraid of pressure, and highly corrosive.
The characteristics of the screw conveyor are: simple structure, small cross-sectional size, good sealing, reliable operation, low production cost, convenient intermediate loading and unloading, and the conveying direction can be reversed or conveyed in opposite directions. During the process, the materials can also be stirred, mixed, heated and cooled. The material flow can be adjusted through the loading and unloading gate. However, it is not suitable to convey materials that are perishable, viscous, easy to agglomerate and bulky. During the conveying process, the material is easily broken, and the screw and the trough are easily worn.

According to the requirements of class specification, we designed & manufactured 12points anchor mooring positioning system for semi-submersible lifting platform. The system is driven by variable frequency motor, adopts a 1500Kn single-cord tension and a 5000Kn supporting load, and uses shiftable reduction gear, dynamic brake system and constant tension control technology.
The screw conveyor has the advantages of simple structure, low production cost, strong sealing, safe and convenient operation, etc. It can be loaded and unloaded at multiple points in the middle. It is widely used in chemical, building materials, metallurgy, grain and other departments. When the inclination angle is β<20°, it can transport powdery, granular and small pieces of materials that are not viscous, not easy to deteriorate, and not easy to agglomerate.
