Screw Conveyor

Product description
Screw conveyors are commonly used material conveying equipment in industrial production. They push materials in a closed channel by the rotation of screw blades. The structure of this machine is not complicated. The core consists of a rotating shaft with blades, U-shaped or tubular material troughs, and is equipped with components such as drive motors. It has many advantages, such as taking up little space, being able to feed materials in a horizontal or inclined direction, and being well sealed to prevent material leakage or dust contamination. From delivering fertilizers and pigments in chemical plants to transporting wheat and flour in grain mills, and then to conveying cement and sand in building materials factories, it can be used in many places to continuously transport materials such as powder and granules. It is flexible and convenient to use.
 
Working principle
The working principle of a screw conveyor is centered on mechanical transmission: when the drive device rotates the screw shaft, the screw blades rotate accordingly and exert an axial thrust on the material. Due to the frictional force between the material and the inner wall of the trough, and the effect of gravity on the material itself, it cannot rotate along with the blades. Instead, under the thrust, it moves along the axial direction of the trough from the feeding port to the discharging port, thereby achieving continuous material transportation. The conveying direction can be flexibly changed by adjusting the rotation direction of the helical blades. This mechanism that converts the rotational power into axial thrust through the helical structure enables the equipment to efficiently handle the conveying requirements of powdery, granular and small block materials.
 
Product characteristics

1.Compact and flexible structure: The equipment is exquisitely laid out, occupies a small area, and can adapt to horizontal, inclined or even vertical installation environments, making it easy to be integrated into various links of the production line.
2. Stable conveying efficiency: The spiral blades continuously rotate to push materials, achieving uniform and continuous conveying, especially suitable for powdery, granular and small block materials.
3. Excellent sealing performance: The closed material trough design can effectively prevent dust from spilling out and materials from getting damp, reducing environmental pollution while ensuring material purity, meeting the requirements of clean scenarios in food, chemical and other industries.
4. Convenient direction adjustment: By changing the rotation direction of the spiral blades, the material conveying path can be easily switched to meet the material transfer requirements of different processes.
5. Low maintenance cost: The core components have a simple structure, and the replacement of vulnerable parts is convenient. Only regular inspection and lubrication are required on a daily basis, reducing the cost of shutdown maintenance.

Application industry

Chemical industry: It is used for transporting powdered or granular chemical raw materials such as soda ash, fertilizers, and pigments, and plays a role in the batching, mixing, and packaging of materials. ​

Grain and food processing: It is suitable for the transportation of materials such as wheat, corn, flour, and powdered sugar, and is commonly found in grain storage, feed processing, and food production lines. ​

In the field of building materials: It can convey building materials such as cement, coal powder and sand particles, and is widely used in concrete mixing plants, building materials storage and conveying systems. ​

Metallurgy and mining industry: It is used for transporting materials such as ore powder, coal powder, and coke, and realizes material transfer in processes such as ore screening and smelting pretreatment. ​

Environmental protection and agriculture: It can handle environmentally friendly materials such as sludge and straw pellets, or transport seeds, feed, etc. in agriculture, meeting the material transportation needs of different scenarios.
