What is the material of the shaftless spiral blade?

Shaftless screw conveyor is a kind of equipment that can realize material transportation and is widely used in various fields. It consists of a spiral blade and a conveying pipe, and the material is conveyed from one end to the other through the rotation of the blade. Regarding the material of the screw blade of the shaftless screw conveyor, there are mainly the following types:

1. Stainless steel

Stainless steel is a material with good corrosion resistance, so in some cases where corrosive materials need to be transported, it is a common choice to use stainless steel as the material of the spiral blade. Stainless steel spiral blades have good acid and alkali corrosion resistance and mechanical strength, and are relatively easy to clean and maintain.

2. Carbon steel

Carbon steel is a common metal material with high strength and hardness. Therefore, in some cases where high-density or high-strength materials need to be transported, it is also a common choice to use carbon steel as the material of the spiral blade. The carbon steel spiral blade has good wear resistance and is suitable for use under high-speed conveying and strong impact conditions.

3. Polyurethane

Polyurethane is an organic polymer material. Because of its excellent properties such as high strength, wear resistance and corrosion resistance, it is widely used in crushing, mixing and conveying processes in food, chemical, pharmaceutical and other fields. The polyurethane helical blade has good elasticity, which can effectively avoid material jamming and sticking, and can also maintain the shape of the conveying pipe well.

It is necessary to select the material of the spiral blade according to the actual situation to ensure that it can meet the requirements of material transportation.
