1. Characteristics of metal: The corrosion of the double-shaft dryer is mainly due to the fact that the material of the dryer is metal, and the chemical activity of the metal is relatively high. When the metal is exposed to humid air for a long time, the metal will occur. Oxidation reaction, and eventually corrosion occurs. Different metal materials of dryers have different easiness for their oxidation reaction to occur.
2. The composition of metal: the purer the metal is, the less likely it is to be corroded. The more impurities in the metal, the easier it is to corrode.
3. Surface condition of parts: when the shape of the parts inside the double-shaft dryer is more complex and the surface is rougher, then its corrosion resistance will be worse. When the internal parts corrode, it will soon cause and The metal where the parts come into contact also corrodes and corrodes extremely rapidly.
Because the power consumption of the paddle dryer is too large, and the drying requirements are high, it needs to be dried twice, so it is an ideal pre-drying in the drying of sticky and high water content materials such as nano-scale calcium carbonate, ink calcium and paper calcium. Equipment, which is used in combination with the tray-type continuous drying emergency, the drying effect is ideal.
