Granulated alumina oxide powder

Granulated alumina oxide powder production process:

1. Grinding. Grind to small enough, about 1μm

2. Feeding. Add additives such as cosolvent and glue, ternary (Al, Si, Ca) or quaternary (Al, Si, Ca, Mg) formula

3. Mixing. At this time, pay attention to the solid content of the slurry, too high or too low will not work. To improve the performance of the granulated powder, the solid content of the slurry must be as large as possible to shorten the spray drying time and obtain approximately spherical particles. The higher the solid content, the greater the viscosity of the slurry, but the excessive viscosity is not conducive to the progress of spray granulation

4. Enter the prilling tower. Pay attention to the sintering temperature, the lower the sintering temperature, the better the stability of the product
