In the operation of the vibrating screen, it is inevitable to cause the scratches, rust, oxidation layer and other problems on the surface of the vibrating screen, which will not only make the appearance of the vibrating screen unsightly, but also accelerate the aging of the vibrating screen. The following are the ways to solve the problems to keep the surface clean.

1, how to clear the dust
The production activities are often carried out in the field where there is a lot of dust in the air. The dust will fall on the surface of the device constantly and these dust can be cleared with water or the alkaline solution. As for some grime with strong adhesion, there is the need to use the high temperature water or steam to clean it up.
2, how to clear floating iron powder or the embedded iron
On any surface, free iron will rust, causing the corrosion of the stainless steel. Therefore, it must be removed. Generally, the dusting flour can be removed along with the dust.
3, the removal of the scratch
In order to prevent the process lubricant or the dirt from accumulating, the mechanical cleaning of the scratches and other rough surfaces should be carried out.
4, the handling of the hot tempering color and oxidation layer
If the stainless steel in the air is heated to a certain temperature in the process of welding or grinding, the both sides of the welding line, the lower surface of the welding line and the bottom will appear the thermal tempering color of chromium oxide. The hot tempered color is thinner than the protective layer, which is visible. The thicker oxide is generally black, which is caused because of the stay under high temperature or the higher degree for long time. When any kind of oxide layers appear, the chromium content of the metal surface will be reduced, resulting in the reduce of the corrosion resistance of these regions. In this case, there is not only the need to eliminate the hot tempered color and other oxide layers, but also to handle the depleted chromium metal layer below them.
