Vibrating screen is widely used because of its material, such as granular, powder, liquid, etc, Vibrating screen sealant is an indispensable part, which can be divided into three kinds of vibrating screen seals according to the different characteristics of the materials. These three kinds of seals are: rubber seal ring, silicone seal ring and polyurethane seal ring, These three seals have different characteristics, according to the material characteristics, correct selection of the sealing cover, can extend the life of the sealing cover, effectively reduce production costs. Next, let's look at the sealing characteristics of these three materials.
1. Rubber seals
The rubber seal ring is the most commonly used sealing ring fitting in vibrating screen equipment, mainly because of its lower cost, Stable performance, but if the screening materials have corrosive, high temperature, high oil properties, the rubber sealing ring is not suitable. Usually if the user has no special material requirements, the shaker manufacturer chooses to install rubber rings when the shaker leaves the factory.
2. Silicone sealants
The silicone seal ring is relatively expensive, but the silicone seal ring has the advantages of stable chemical property, strong thermal stability, high adsorption performance and relatively high mechanical strength. If the materials selected by the user have relative characteristics, the silicone seal ring should be chosen.
3. Polyurethane sealants
Polyurethane seal ring is the most unusual sealing ring for vibrating screen equipment, the main reason is the high cost. Polyurethane seal rings are oil-resistant, corrosion-resistant and high temperature-resistant. Users with relevant characteristics should choose to install polyurethane seal rings.
