What is a twin screw conveyor?

For what is a twin screw conveyor is a question asked by a user a few days ago. At the same time he also asked: What is a twin screw conveyor? How does a twin screw conveyor deliver material? What is the relationship between the direction of rotation and the material being conveyed. According to these several questions, a summary of the following is summarized as follows:

First: What is a twin screw conveyor?

The screw conveyor is commonly known as auger, and is suitable for horizontal conveying of granular or powdery materials, inclined conveying, vertical conveying and the like. The transport distance varies depending on the deformity, generally from 2 meters to 70 meters.

Second: How does the twin screw conveyor realize the conveying of materials?

Conveying principle: The rotating spiral blade transports the material and carries it on the screw conveyor. The force that causes the material to not rotate with the screw conveyor blades is the weight of the material itself and the friction of the material of the screw conveyor casing.

Structural features: The spiral conveyor is welded with spiral blades on the rotating shaft. The surface shape of the blade has a solid surface type, a belt surface type and a blade surface type according to different materials. The screw shaft of the screw conveyor has a thrust bearing at the end of the material moving direction to give the axial reaction force of the spiral with the material. When the length of the machine is long, the intermediate hanging bearing should be added.

Third: What is the relationship between spiral rotation and conveying materials?

A twin screw conveyor is a screw conveyor having two rotating shafts respectively welded with rotating blades. To put it bluntly, the two screw conveyors are organically combined to form a screw conveyor.

The direction of rotation of the rotating shaft of the screw conveyor determines the conveying direction of the material, but in general, the screw conveyor is designed to design the rotating blades according to the single conveying. When transported in the reverse direction, the life of the conveyor is greatly reduced.
