Screw Conveyor

Product description
Screw conveyor is a kind of continuous conveying equipment for conveying bulk materials, and is often called the skein. It is mainly composed of a driving device, a helix, a chute, a bearing and other components. When working, the driving device drives the spiral body to rotate in the tank, using the friction between the spiral blade and the material and the pushing effect of the spiral body, the material is transported along the tank from one end to the other end. Screw conveyor has the advantages of simple structure, good sealing, small footprint, flexible adjustment of transportation direction, etc., widely used in chemical, building materials, grain, metallurgy and other industries, can horizontal, inclined or even vertical transport powder, granular and small block materials, such as cement, sand, grain, ore, etc., but it also has a crushing effect on the material, limited transportation distance and other limitations.
Working principle
The screw conveyor relies on the rotation of the screw blade to achieve material transportation. When the motor drives the spiral shaft to rotate, the spiral blade rotates accordingly. The material located in the tank is subjected to a push along the direction of the spiral due to the rotation of the spiral blade. This thrust can be decomposed into the circumferential force that rotates the material around the spiral axis and the axial force along the spiral axis. Due to the friction between the material and the tank wall, the circumferential force is offset, and the axial force pushes the material to move in the direction of the outlet in the tank, so as to complete the conveying process of the material from the feed end to the discharge end, and achieve efficient and continuous material transmission, which is suitable for the conveying of a variety of bulk materials in different scenarios.

Product characteristics
1. Simple structure: mainly composed of helix, chute, drive device and bearing, no complex transmission parts and attachments, low manufacturing and installation cost, and not easy to fail during operation.

2. Good sealing: the use of fully closed tank and spiral blade, can effectively prevent material leakage and dust flying, not only to ensure the integrity of the material, but also to maintain a clean working environment, suitable for conveying toxic, harmful, flammable, explosive and other special materials.

3. Variable conveying direction: By changing the rotation of the spiral blade and the steering of the drive motor, it can easily achieve two-way conveying of materials, and can also carry out horizontal, inclined or vertical conveying according to actual needs. The layout is flexible and diverse, and can adapt to different production processes and site requirements.

4. High conveying efficiency: the continuous rotation of the spiral blade promotes the stable progress of the material, which can transport a large amount of material in a unit time, and the conveying amount of the material can be accurately controlled by adjusting the parameters of the motor speed, the diameter of the spiral blade and the pitch, to meet the needs of different production scales.

5. Strong adaptability to materials: can transport a variety of powder, granular and small block materials, such as cement, pulverized coal, grain, sand, etc., the physical and chemical properties of the material requirements are relatively low, in chemical industry, building materials, metallurgy, food and other industries have been widely used.

6. Low maintenance cost: Due to the relatively simple structure and fewer moving parts, daily maintenance work is mainly focused on the inspection and maintenance of spiral blades, bearings and drive devices, the required maintenance workload is small, the maintenance cost is
low, can effectively reduce the operating cost of equipment and improve production efficiency.
