Screw Conveyor

Product description
Screw conveying is an efficient material transportation method. It relies on the helical body composed of helical blades and rotating shafts to complete material transportation in closed or semi-closed material troughs. Its structure is simple and compact, occupies a small space, and is convenient for installation and maintenance. It has good sealing performance and can effectively prevent material leakage and dust from spreading out. It can achieve flexible conveying in horizontal, inclined and even vertical directions, and also support multi-point feeding and discharging. It is applicable to a wide range of materials, from powder, granules to small blocks, and plays a key role in the continuous and stable transmission of materials in the production processes of multiple industries such as chemical engineering, grain, and building materials.
 
Working principle
The working principle of screw conveying is: The drive device drives the rotating shaft to rotate at high speed, and the helical blades fixed on the shaft rotate accordingly. Due to the friction between the material and the helical blades as well as the inner wall of the material trough, the material cannot move in a circular motion along with the blades. Instead, under the action of the axial thrust generated by the rotation of the helical blades, it is continuously pushed forward along the axial direction of the material trough, just like a nut pushed by a screw. Realize the conveying of powdery, granular and small block materials in horizontal, inclined and even vertical directions.
 
Product characteristics
 
Conveying characteristics
Stable conveying: The uniform rotation of the spiral blades enables the material to be conveyed forward steadily and continuously, ensuring the continuity of the production process.
 
Diverse conveying: It can convey materials in various forms such as powder, granules, and small blocks, and has a wide range of applications.
 
Flexible conveying direction: It can achieve material conveying in horizontal, inclined or vertical directions according to actual production needs, and can also combine different directions for complex conveying.
 
Structural characteristics
Simple and compact structure: Mainly composed of a screw body, a material trough and a drive device, etc., the overall structure is simple, occupies a small space and is easy to install in different production environments.
 
Good sealing performance: The closed or semi-closed material trough design can effectively prevent material leakage and dust flying, which not only protects the environment but also avoids material waste and pollution.
 
Operation and maintenance characteristics
Easy to operate: By controlling parameters such as the rotational speed of the drive device, the conveying speed and flow rate of the material can be conveniently adjusted, making the operation simple and fast.
 
Convenient maintenance: The structure is relatively simple with fewer components, making daily maintenance and inspection work relatively easy, which can reduce the maintenance cost and downtime of the equipment.
 
Other features
Multi-point feeding and discharging: Multiple feeding and discharging ports can be set at different positions in the material trough to meet the requirements of material addition and distribution in different production processes, thereby enhancing the flexibility and degree of automation in production.
 
Minimal damage to materials: During the conveying process, the friction and collision that the materials are subjected to are relatively small. For materials that are prone to breakage, wear, or have special shape requirements, it provides good protection.
