Screw conveyors are widely used in various sectors of the national economy such as grain industry, building materials industry, chemical industry, machinery manufacturing, and transportation. The screw conveyor is mainly used to convey various powdery, granular and small lump materials. The bulk materials conveyed include grain products such as grains, beans and flour, building materials such as cement, clay and sand, salts and alkalis. , fertilizers and other chemicals, as well as coal, coke, ore and other bulk cargo. The screw conveyor is not suitable for transporting materials that are perishable, viscous, bulky and easy to agglomerate. In addition to transporting bulk materials, screw conveyors can also be used.
The screw conveyor can complete the mixing and stirring operation while conveying materials. In ports, screw conveyors are mainly used for unloading trucks, ship unloading operations, and horizontal and vertical conveying of bulk materials in warehouses. The screw unloader, which uses the horizontal screw shaft in direct contact with the material to unload the material layer by layer from both sides of the carriage, has been successfully used for many years in China.
Generally, screw conveyors have the following characteristics:
1. Simple structure, far away from conveying;
2. Low cost and less pollution to the environment;
3. It can be loaded at any point, or unloaded at many points;
4. It can be mixed and stirred during the conveying process;
5. The trough has high rigidity and can withstand a certain bending moment.
