Because the ultrasonic vibrating screen has a wide range of materials, such as granular, powder, liquid, etc., the sealing ring is an indispensable part. Generally, according to the different characteristics of materials, three kinds of ultrasonic vibrating screen sealing rings of different materials can be selected to achieve good screening effect. These three kinds of sealing rings are: rubber sealing ring, silicone sealing ring and polyurethane sealing ring. These three kinds of sealing rings have different characteristics, According to the material characteristics, the correct selection of the sealing ring can prolong the service life of the sealing ring and effectively reduce the production cost. Below, let's learn about the advantages of the sealing rings made of these three materials

1. Rubber sealing ring

Rubber sealing ring is a commonly used sealing ring accessory, mainly because of its low cost and stable performance. However, if the selected materials have corrosive, high-temperature, oily and other characteristics, the rubber sealing ring is not suitable. Generally, if there are no special requirements for the user's materials, the rubber ring shall be installed when the vibrating screen leaves the factory.

2. Silicone sealing ring

The cost of the silicone sealing ring is relatively high, but the silicone sealing 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 relevant characteristics, the silicone sealing ring should be selected.

3. Polyurethane sealing ring

Polyurethane sealing ring is not often used in equipment, mainly due to high cost. The polyurethane sealing ring has the characteristics of oil resistance, corrosion resistance and high temperature resistance. Users who screen materials with relevant characteristics should choose to install the polyurethane sealing ring.
