Alumina Ceramic insulator flange sealing ring
Reputation depends on quality, quality comes from Hard!
Alumina Ceramics:
Shenzhen Hard ceramic sealing ring uses advanced thermal vulcanization process to vulcanize special alumina corundum wear-resistant ceramic in special rubber according to a certain layout. The structure not only exerts the high temperature wear resistance and corrosion resistance of the alumina ceramic, but also exerts the characteristics of high strength, high toughness and good sealing property of the rubber material, and is integrated design, easy to replace and install.
There are two sealing devices between the vertical grinding disc holder and the frame body. If the sealing of these places is damaged, the air leakage will be severe, which will affect the wind speed of the spout ring and cause the slag to increase. Generally, there are several sets of sealing rings for use with the mill, but the sealing ring needs to be replaced as a wearing part at a time. It has to be imported from abroad at an expensive price, and the delivery time is not guaranteed.
After being used by many cement plants, the service life is equivalent to that of imported seal rings, which can completely replace expensive imported products.
main feature:
l Wear-resistant, 50 times longer than ordinary rubber seal ring
l Good sealing performance
l resistant to 250 ° C high temperature
l Easy to install and replace
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
