Structure Diagram of Screw Feeder

The screw feeder is a commonly used powder and granular material conveying equipment, and its structure is mainly composed of a screw, a conveying pipe, a transmission device, a support frame and other parts. Let's take a closer look at its components.

1. Spiral

The screw is the main part of the screw feeder, and its function is to transport the material from the inlet to the outlet. The screw is generally made in the form of a cylinder or a triangular rod, and the selection of the screw pitch and rotation speed depends on the nature of the material and the conveying distance.

2. Delivery pipe

The conveying pipe is the passage for the screw feeder to convey the material, and it is generally made of seamless steel pipe. Its main function is to transmit the rotating force of the screw and push the material forward along the conveying pipe.

3. Transmission

The transmission device is the core part of the screw feeder, mainly composed of motor, reducer, coupling and so on. Its function is to transmit the power of the motor to the screw, and control the rotation speed and direction of the screw, so as to realize the conveying of materials.

4. Support frame

The support frame is the foundation of the structure of the screw feeder, providing stable support for the screw and conveying pipe. The support frame is generally composed of steel structure and angle iron, which has sufficient strength and stability.

The structural characteristics of the screw feeder:

1. Strong adaptability

The screw feeder is suitable for conveying a variety of powdery or granular materials, such as cement, coal powder, chemical fertilizers, food, etc.

2. Long conveying distance

The conveying distance of the screw feeder is relatively long, up to about 80 meters, and it is suitable for conveying materials across multiple workshops or storage bins.

3. Small size, flexible layout

Due to the relatively compact structure of the screw feeder part, its volume is relatively small, and it can be flexibly installed in different positions.

4. Stable and reliable operation

The overall structure of the screw feeder is simple, there are no wearing parts and complicated debugging links, and it has the advantages of stable operation and high reliability.

Generally speaking, the screw feeder is composed of screw, conveying pipe, transmission device and support frame, etc. It has the characteristics of strong adaptability, long conveying distance, small size, stable and reliable operation, etc., and is widely used in the production process of various industries middle.
