With regard to the corrosive condition of sawdust rotary dryer, it is inevitable. What we can do is to prevent it. The sawdust drying machine is generally composed of plates, drums and weld assemblies. For different parts, the anti-corrosive measures are different. The commonly-used measures are as follows.

We weld the parts of sawdust drying machine with the Cr Stainless Steel. The traditional materials for welding parts are easy to be broken or corroded, so they are potential threats to the service life of sawdust dryer machine. Even though the Cr Stainless Steel has shortcomings like poor heat conductivity and high swell factor, it still can be regarded as the best welding material by virtue of the strong resistance to corrosion and unbreakable capacity.

Since many parts of sawdust rotary dryer are forged with carbon steel, they are easy to be rusted after long-term working. Necessary manual derusting has to be done regularly. With regard to the passivating treatment, it can make the rusted surface back to normal and form compact anti-rust film on the recovered surface. Actually, the passivating treatment is an electrochemical reaction.
