Introduction of Screw Conveyors for Powders and Bulk Solids

Powder and bulk solids screw conveyors are a special type of screw conveyor designed for conveying powders and bulk solids. It uses the combination of screw shaft and screw blade to push the powder and bulk solid material along the axial direction, so as to achieve the purpose of conveying. This type of screw conveyor typically has denser screw blades to better handle fine powders and granular materials and prevent material buildup or clogging.

What is screw conveyors for powders and bulk solids?

The structure of the screw conveyor for powders and bulk solids generally includes the screw, the bearing seat, the inlet, the outlet, the transmission device and the supporting frame. Among them, the screw is the core component of the entire conveyor, usually composed of a screw blade and a hollow shaft, and the arrangement of the screw blade can be left-handed or right-handed according to specific needs. The bearing housing is used to support and fix the screw shaft to ensure its stable operation. The material inlet and outlet are respectively used for the import and export of materials, and the transmission device drives the screw shaft to rotate through the motor to realize the conveying function of materials. The support frame is used to fix and support the entire conveyor to ensure its safe operation.

What is the working principle of screw conveyors for powders and bulk solids?

The working principle of the screw conveyor for powders and bulk solids is to use the screw blade to rotate along the direction of the screw axis. Due to the friction between the screw blade and the material, the material is pushed forward with the rotation of the screw shaft. During the material conveying process, due to the design of the spiral blade, the material is continuously lifted and pushed, and finally discharged through the discharge port. At the same time, the screw conveyor can also control the conveying speed and flow of materials by adjusting parameters such as screw speed, conveyor inclination and feeding amount.

What is the benefits of screw conveyors for powders and bulk solids?

1. Simple structure: The structure of the screw conveyor for powders and bulk solids is relatively simple, consisting of a small number of parts, easy to install and maintain.

2. High adaptability: The screw conveyor is suitable for conveying various powder and bulk solid materials, including granules, granular materials, powders, pasty materials, etc.

3. High safety: When the screw conveyor is conveying materials, there is almost no friction between the materials and the machine, so the safety is high during operation.

4. Long conveying distance: The screw conveyor can convey materials over a long distance, up to about 80 meters.

What is the role of screw conveyors in powders and bulk solids?

1. Conveying materials: Screw conveyors can convey powder and bulk solid materials from one location to another. Through the rotating helical blade, the material is pushed to move along the pipe or groove, realizing the continuous conveying of the material.

2. Mixing materials: The screw conveyor can also mix materials of different components by adjusting the rotation speed and angle. During the conveying process, the material will be continuously rolled and stirred, so as to achieve the effect of mixing.

3. Adjust the delivery volume: The delivery speed of the screw conveyor can be adjusted by controlling the motor speed, so as to realize the control of the delivery volume. By changing the rotation speed and rotation direction of the screw blade, forward, reverse, continuous or intermittent conveying can be realized to meet different process requirements.

4. Connecting the production line: The screw conveyor can be used as a link in the production line to connect materials between different processes. It can transport the materials produced in the production process from one device to another to realize the continuity of the production process.

5. Reliable and stable: The screw conveyor adopts a simple and compact design, and its operation is stable and reliable. It has high conveying efficiency and low energy consumption, and can adapt to different working environments and process requirements.
