Due to the raw materials or the way they are used, asphalt mixing plants will be subject to a certain degree of wear during daily use. If they are not controlled or repaired in time, they may corrode once they are in contact with air, rainwater, etc. for a long time. If the parts of the asphalt mixing plant are severely corroded, the service life and normal operation of the entire equipment will be affected.

Therefore, it is very important for asphalt mixing plants to do a good job of various treatments to prevent their parts from being corroded. In order to achieve this goal, on the one hand, when selecting materials for the asphalt mixing plant, materials with good corrosion resistance should be selected as much as possible. On the other hand, it is necessary to reduce the corrosion of the surface of parts by isolating air and other methods, and also prevent fatigue damage of parts, such as fracture and surface peeling.
In order to prevent the occurrence of the above phenomena, a relatively gentle section can be selected for filtration during production; penetration, quenching and other methods can also be used to increase the hardness of parts; and when designing the shape of parts, the effect of reducing friction planning should also be considered.
