Screw Conveyor

Product description
The screw conveyor is a continuous conveying equipment that uses the rotating screw blade to push materials forward along the trough of the casing. It is widely used in agriculture, mining, construction, chemical and other fields. Its structure mainly consists of screw blades, casing, drive device and inlet and outlet ports. It has the characteristics of simple structure, small cross-sectional size, good sealing, convenient operation and easy maintenance. It can convey powder, granular and small block materials such as flour, grains, sand and gravel, and coal powder horizontally, inclined or vertically. It can effectively reduce the scattering and pollution of materials during the conveying process and undertake the short-distance transportation and distribution of materials in the production line.
 
Working principle

When the driving device (such as a motor) drives the spiral shaft to rotate, the spiral blades fixed on the shaft rotate synchronously. Due to the certain gravity and internal friction of the materials, and the constraint of the machine shell groove body on the materials, the materials do not rotate along with the spiral blades but move forward along the inner wall of the machine shell under the thrust of the blades.
During this process, the helical surface of the spiral blades continuously exerts axial thrust on the materials, causing the materials to be gradually transported from the feed port to the discharge port. Depending on the different conveying directions, the rotation direction of the spiral blades (left-handed or right-handed) and the rotation direction of the shaft can be adjusted to achieve horizontal, inclined or vertical material transportation. At the same time, the sealing structure of the machine shell can reduce the scattering and dust generation of the materials during the conveying process, ensuring the efficiency and environmental friendliness of the conveying process.

 
Product characteristics

1. The structure is simple, easy to manufacture and maintain. It mainly consists of spiral blades, casing, drive device, etc. With few components, the processing and installation are relatively easy. Daily maintenance only requires regular checks on blade wear, bearing lubrication, etc., and the cost is relatively low.
2. The cross-sectional size is small, saving space. The body is compact and can be installed in narrow spaces. It is particularly suitable for scenarios with dense production line layouts and can effectively utilize factory space.
3. Good sealing performance, reducing pollution. The casing is mostly of a sealed design, which can reduce the scattering, dust flying or odor diffusion during material transportation, and is suitable for transporting materials with a lot of dust, easy pollution or volatility.
4. Flexible transportation direction. It can not only be horizontally transported, but also tilted or vertically transported, which can meet the requirements of different process layouts and achieve multi-angle transfer of materials.
5. Easy operation and strong controllability. By adjusting the rotational speed of the drive motor, the transportation volume can be flexibly controlled, and it can also be linked with other equipment (such as silos, screening machines) to achieve automated production.
6. Suitable for various material types. It can transport powdery, granular, and small block materials, with a wide range of applicability.
