Tabular alumina is a kind of pure sintered alumina that does not add any additives such as MgO, B2O3 and is completely sintered and shrinks. It has coarse crystals and a well-developed α-Al2O3 crystal structure. The content of Al2O3 is more than 99%. Crystal-like structure with small pores and many closed pores. The porosity is roughly the same as that of fused alumina. It has high purity, good volume stability, and minimal re-firing shrinkage. The refractory or castable used to produce refractory materials, or castables have good properties after high-temperature treatment. Thermal shock stability and bending strength. So what is the production process of tabular corundum?
Australian industrial Alumina ⇒ Raw material Chemical physical analysis ⇒ Ball mill grinding⇒ Making Alumina Powder Ball by Disk Granulator ⇒ Drying ⇒ Natural gas shaft kiln (1800－1900℃) ⇒ Chemical analysis ⇒ Crushing and screening ⇒ Physical analysis ⇒ Packaging ⇒ Warehousing
1. Raw material: Grind 60# Australian alumina powder into 380# with ceramic ball mill
2. Making raw balls: Making 380# fine powder to raw Ball using disk granulator
3. Raw ball drying: Drying with natural gas drying tower at 400-500 degrees Celsius for 20 hours
4. Raw ball sintering by Natural gas shaft kiln: During the 22 hours of passing through the natural gas shaft kiln, rapid heating, and rapid cooling
5. Crushing and screening: Barmac and Linear Vibrating Screen
6. Ball mill to grind fine powder: Fine powder below 1mm diameter
