High alumina ceramics are an excellent solution for severe wear zones which do not see dynamic conditions such as vibrations, thermal shocks, impact etc. These tiles are available in pastable, boltable, weldable or mechanical interlocking forms and can easily be used to cover large wearing areas quickly. These tiles are a preferred choice in highly abrasive pneumatic conveying systems, cyclones, fly-ash/coal pipelines etc.
AL2O3; 92% OR 95%
—–High hardness, abrasion resistanct.
—–One tile with one metallic washer and small cylinder.
Size: 150×100×6-30(TK)mm/ 75×100×12.5-25(TK)mm, etc.
