The screw conveyor is a general-purpose material conveying device, which mainly uses the thrust generated by the rotation of the screw blade to realize the transportation of the real material, and transports the material from the inlet to the outlet.
Single-shaft screw conveyor is a common material conveying equipment. It is mainly composed of a screw shaft, a material inlet and a material outlet. It is widely used in building materials, metallurgy, chemical industry, light industry, food and other industries.
Single shaft screw conveyor has 4 advantages and disadvantages
The advantages, disadvantages and applications of single-shaft screw conveyors will be introduced in detail below.
Advantages of single shaft screw conveyor
- Simple structure, small size and light weight :The overall structure of the single-shaft screw conveyor is simple, only composed of a screw shaft, a feed port and a discharge port, so the volume of the whole machine is relatively small, the weight is also very light, and it is easy to install and maintain.
- cut costs :Compared with other types of material handling equipment, single-shaft screw conveyors are relatively inexpensive, and due to their simple construction, the cost of repair and replacement parts is also relatively low.
- Wide range of applications :The single-axis screw conveyor can be applied to various conveying materials and site environments. It can convey materials with less solid particles and impurities, liquid, semi-solid, powder and other substances. Its conveying capacity and conveying distance can be flexibly adjusted.
- Continuous delivery :The single-axis screw conveyor can carry out continuous and uninterrupted conveying, which can meet the requirements of the production line, and because of its simple structure, it can be conveniently chain conveyed.
The disadvantages of single-axis screw conveyor
- RPM limited : The single-axis screw conveyor is driven by a reducer, so its speed is limited, and the conveying speed is relatively slow, which may not be able to meet some materials that require high-speed conveying.
- Conveying capacity is limited: Limited by bearings, intermediate supports and other components, the conveying capacity of the single-shaft screw conveyor is relatively small. For some materials that need to be conveyed in large quantities, a larger type of conveyor is required.
- Conveying distance is limited:Due to the structural limitation of the single-axis screw conveyor itself, its conveying distance is relatively short, and it is generally not suitable for long-distance conveying.
Conclusion
The single-shaft screw conveyor system has the characteristics of simple structure, low cost, and wide application range. The disadvantage is that the conveying distance and conveying speed are relatively low, but it has been widely used in many fields and played an important role.
At the same time, since different material conveying requires different screw blades and screw shafts, it is very important to design and select a single-shaft screw conveyor suitable for current production needs.
