Because many materials need to be dried in some processing and production, dryers have been developed, and there are more and more dryers with different specifications for different materials, which can meet the drying needs of different enterprises. During the use of the dryer, there may be many problems, such as the corrosion of the dryer. What are the specific reasons for the corrosion of the dryer?

1. The characteristics of metal

The blade dryer is made of metal, and the chemical activity of metal is relatively active. When the metal is exposed to humid air for a long time, the metal will undergo oxidation reaction and corrosion will occur.

2. Composition of metal

The purer the metal, the less likely it is to be corroded. When the impurity content in the metal is more, the more likely it is to be corroded.

3. Surface condition of parts

If the shape of the internal parts of the blade dryer is more complex, the surface will be rougher, and of course its corrosion resistance will be worse. When the internal parts are corroded, the metal in contact with the parts will be corroded soon, and the corrosion rate is very fast.

4. Environment

When the working environment of the blade dryer is high in temperature and humidity, or there are more oxygen and chloride ions in the environment, it is easy to react with the double-shaft blade dryer and accelerate the corrosion degree of the blade dryer.

To sum up, we can find that the main reasons for the corrosion of the dryer are: metal characteristics, metal composition, surface condition of parts and working environment of the dryer.
