As we know, the material may include the corrosion in sand processing line. So how to protect the device from the corrosion becomes an important issue.
The first thing is to add the lining of PU. Lining material can prevent local corrosion and the screen frame edge contact. (The picture on the right is PU lining.)
Secondly, we must brush the anticorrosive paint. You may ask that how long the anticorrosive paint can protect the device. The answer is that it is determined according to the yield and size of the material. If the device runs for eight hours a day, anti-corrosion coatings can protect the machine for at least a month. The best way is to brush anticorrosive paint regularly to make the device have a long service life.
