Screw Conveyor

Product description
Screw conveyor is an efficient and widely used continuous conveying equipment. Its main structure is a spiral blade through a closed long groove or cylinder, tightly welded to the rotating shaft. When working, the motor drives the rotating shaft to rotate at high speed and drives the spiral blade to rotate synchronously. The material enters from the feed port, is pushed by the spiral blade, as if it is pushed forward continuously by an invisible hand, and is transported smoothly along the tank or cylinder to the discharge port. It can complete the material transportation in the horizontal, inclined and even vertical direction, suitable for grain, cement, coal and other powdered, granular and small block materials, with simple and compact structure, good sealing, stable and reliable conveying process, small footprint and other advantages, effectively improve the efficiency and accuracy of the material transfer link in industrial production.

Working principle
When the motor of the screw conveyor starts, the motor drives the screw shaft to rotate. The spiral blade is fixed on the spiral axis and rotates with the spiral axis. The material enters the conveyor from the feed port. Due to the rotation of the spiral blade, the material is subjected to the normal thrust and friction of the blade. Normal thrust makes the material produce a component force along the direction of the spiral axis, so as to push the material forward; Friction makes the material rotate with the spiral blade, but because of the friction between the material and the tank or pipe wall, the rotation of the material is limited, so that the material is mainly transported along the axis and finally discharged from the discharge port. In this process, factors such as the pitch of the spiral blade, speed and the characteristics of the material will affect the conveying speed and conveying capacity of the material.

Features & Benefits
1. Simple structure: mainly composed of spiral shaft, spiral blade, chute, drive device and other parts, relatively simple structure, low manufacturing and maintenance costs.

2. Good sealing: the tank is usually closed, which can effectively prevent material leakage and dust flying, reduce pollution to the environment, especially suitable for conveying toxic, flammable, explosive or dust materials.

3. High conveying efficiency: the rotation of the spiral blade can continuously push the material forward, the conveying speed is stable, and can be adjusted according to needs to meet the requirements of different production scales.

4. Flexible conveying direction: Material conveying can be carried out in horizontal, inclined and even vertical directions, which can adapt to different process flows and site layout requirements.

5. Strong adaptability: can transport a variety of types of materials, including powder, granular, small blocks, such as grain, cement, sand, coal and so on.

6. Easy operation: the start, stop and operation control of the equipment is relatively simple, easy to realize automatic operation, and reduce the manual labor intensity.

7. Small space: the overall size is relatively small, and it can be customized according to the field space, and can complete the material handling task in a limited space.

8. Small material damage: In the conveying process, the friction between the material and the spiral blade and the material groove is relatively small, and the damage degree of the material is low, which is suitable for conveying some materials that are easily broken or have high appearance quality requirements.
