Thanks to the Nano technology and special raw materials in the new formulation, the OK909 “White & Black” (OK909WB) anti-bending roller performs excellent in rapid cooling environment of roller kilns.
By using the particular thrice pressing and twice firing, and perfect combination of alumina and SiC material, the roller has the both advantages of mullite ceramic roller and silica carbide roller:
-extreme anti-wearing ability
-extreme strong resistance against creepage and corrosion.
OK909WB roller is the best partner of cooling zone for wide kiln to produce big tiles.
