What material is screw conveyor shaft?

Screw conveyor is a kind of mechanical equipment for continuously conveying materials, generally composed of motor, reducer, screw pump, bearing, input port and output port, etc. Its function is to transport bulk materials such as powder, small particles, and blocks from one place to another, and can complete complex operations such as mixing, heating, and cooling. In the screw conveyor, the shaft is one of the key components, which plays an important role in carrying, rotating and conveying materials, so the material of the shaft is very important.

Common shaft materials are as follows:

1. Carbon steel shaft: mainly composed of C, Mn, Si and other elements, the price is low, and it is widely used in occasions where the transportation demand is not high, such as building materials, chemical industry and other industries.

2. Stainless steel shaft: Composed of Cr, Ni and other elements, it has good corrosion resistance. It is suitable for food, pharmaceutical and other industries, and has good performance in harsh environments such as high temperature, high humidity, and high acid and alkali.

3. Aluminum alloy shaft: It has good mechanical properties and corrosion resistance, and is light in weight. It is suitable for light equipment with a small amount of conveying materials.

4. Titanium alloy shaft: It has high corrosion resistance, strength and lightweight characteristics, and is more expensive. It is suitable for special occasions, such as high temperature, high acid and alkali and other harsh environments.

Therefore, when selecting the shaft material of the screw conveyor, it is necessary to determine the material of the shaft according to the nature of the conveyed material and the operating environment, so as to achieve the best effect and the longest service life.
