Screw Conveyor

Product description
Screw conveying is a common material transportation method. It achieves material transportation in closed or semi-closed material troughs through the spiral body formed by spiral blades and rotating shafts. Its structure is compact and occupies a small area. It can be flexibly applied in horizontal, inclined and even vertical conveying scenarios, and is suitable for powdery, granular and small block materials. In industries such as chemical engineering, grain, and building materials, screw conveyors have become important equipment for material transportation in industrial production due to their advantages of high efficiency, easy operation, strong sealing, and the ability to feed and discharge materials at multiple points.

Working principle
The working principle of screw conveyor is as follows: The screw blades are fixed on the rotating shaft. When the rotating shaft rotates under the drive of the driving device, the screw blades will perform circular motion. Due to the frictional force between the material and the helical blades as well as the material trough, under the pushing effect of the helical blades, the material cannot move in a circular motion along with the blades but moves along the axial direction of the helical blades, thereby achieving the transportation of the material within a closed or semi-closed material trough.

Product characteristics
1. Simple structure: It is mainly composed of a screw body, a driving device and a material trough, etc. The structure is compact, occupies a small space, and is easy to install and maintain.

2. High conveying efficiency: The rotation of the spiral blades can continuously push the material forward, achieving a high conveying capacity and a stable conveying speed.

3. Good sealing performance: The material trough is usually closed, which can effectively prevent material leakage and dust flying. It is suitable for conveying materials that are prone to dust, toxic or corrosive, and can protect the environment and the safety of operators.

4. Flexible conveying direction: It can be conveyed horizontally, inclined or vertically according to actual needs, and can also achieve combined conveying in multiple directions to meet the requirements of different production processes.

5. Multi-point feeding and discharging are available: Feeding ports and discharging ports can be set at different positions during the conveying process, facilitating the addition and distribution of materials and facilitating the realization of automated production.

6. Minimal damage to materials: During the conveying process, the friction between the materials and the spiral blades as well as the material trough is relatively small, causing less damage to the particle size and shape of the materials. It is suitable for some materials that are prone to breakage or have special shape requirements.

7. Strong adaptability: It can convey various types of materials, including powder, granules, small blocks, etc., and is widely used in multiple industries such as chemical engineering, grain, building materials, and metallurgy.
