Anti spaling high alumina brick

Anti spaling high alumina brick introduction
Anti spalling high alumina brick is specially produced for cement rotary kiln lining material. This kind of brick has better erosion resistance, strenght, thermal shock resistance, anti spalling resistance than common high alumina brick. The best grade clinker and synthetic compost contains ZrO2 are raw mateiral.

Anti spaling high alumina brick features
Anti-spalling high alumina brick has good thermal shock stability, high RUL, high temperature strength, alkali resistance, clinker erosion resistance, better mechanical strength, high temperature wear resistance, anti-spalling, anti-crust, low thermal conductivity, long service life and so on.
