The average life of the castable alumina ceramic was 3-4 weeks, compared to 18 months for Alanx's CG896 composite replacement. CG896 was chosen for its combination of strength, thermal shock resistance, and wear resistance. To see a photo of a blast furnace tuyere click here.
Many power plants use fans to convey pulverized coal to the boiler.
The interior of the fan housing experiences excessive wear. In the transfer of coal, CMC solved cracking failures experienced with alumina ceramics in the same locations, and have run for over 2 years. In silica sand attrition mills, Alanx CG896 lasted twice as long as tungsten carbide coated steel. Otherwise known as jet mills, micronizers are used in the final milling process of TiO2 at milling speeds of mach 2-3. Alanx CG896 lasted 6 times longer than alumina, and did not have thermal shock failures as the alumina systems exhibited.
