What are the types of screw conveyor?

Screw conveyor is a common material conveying equipment, which is widely used in industrial production. It transports materials from one place to another through spiral blades, and has the advantages of strong conveying capacity, long transmission distance, and wide application range. There are several types of screw conveyors:

1. Ordinary screw conveyor: It is the simplest and most common screw conveyor, which is composed of screw blades, feeding port, discharging port, transmission device and so on. Ordinary screw conveyors are suitable for conveying powdery, granular and sheet materials, and have the advantages of simple structure and convenient installation.

2. Double-shaft screw conveyor: It is a conveying device formed by the rotation of two independently rotating spiral blades. It has the advantages of large conveying capacity, long conveying distance, and the ability to handle a large amount of materials. The double-shaft screw conveyor is suitable for conveying difficult-to-handle materials such as high viscosity, moisture, easy to coalesce, and easy to stick.

3. Hollow screw conveyor: It is a screw conveyor with a hollow pipe inside the screw blade. It has the function of drying and cooling while conveying materials. It is suitable for materials that need to be dried or cooled at the same time during the production process.

4. Spiral elevator: similar to the screw conveyor, but the shape and number of blades are different, which can convey materials along the straight line height direction, and is suitable for occasions that require high material height, conveying distance and power.

5. Spiral mixer: It is a device for mixing two or more materials. It can mix different materials evenly through the rotation of the spiral blade, and is suitable for the production of materials that need to be mixed.

To sum up, the screw conveyor is a kind of material conveying equipment with great practical value. There are many kinds of screw conveyors, which can be selected according to different production needs.
