During the assembly process of the sander, there are many kinds of sealing rings, including O type, U type, etc. The commonly used sealing ring materials are: nitrile butadiene rubber, chlorinated nitrile butadiene rubber, silicone rubber, fluororubber, polyurethane, etc. Their chemical resistance, heat resistance, wear resistance, deformation resistance, acid and alkali resistance are different, so sexual selection should be made according to the characteristics of the materials and slurry contacted by the sander, Ensure that the stability of the sand mill is relatively extended as much as possible while ensuring its sealing use. Generally, O-ring is chosen as the sealing material in the sand mill to ensure the stability of the overall sealing.

The specific type of sealing ring for the Langling sanding machine still needs to be consulted with Langling's engineers in detail!
