Alumina Ceramic Lining Wear And Corrosion Resistance Technical Alumina Lining And Tiles
Alumina ceramic lining has high wear resistance, acid and alkali resistance, and effectively prolongs the service life of the equipment. Alumina ceramic is considered to be the best choice for wear-resistant and corrosion-resistant materials; the wear resistance of ceramics is 266 for special manganese. The ratio is 171.5 times that of high chromium cast iron; the hardness is much higher than that of wear resistant steel and stainless steel.particularly the lining of separators, bunkers, chutes, conveyor belt transfer points.These lining typical outlast other solutions, like chrome carbide or AR plate by 10 times the wear life and with less weigth.
