Alumina calcination, alpha alumina, calcination rotary kiln, high-temperature calcination, alumina micro powder, ceramic-grade alumina, refractory materials, bauxite roasting, industrial alumina

4. Description:

The alumina calcination production line is a specialized high-temperature calcination system used to produce high-purity α-Alumina (Al₂O₃). Using a rotary kiln calcination process, aluminum hydroxide or alumina hydrate is converted into stable alpha alumina at temperatures ranging from 1200°C to 1400°C. The resulting α-Alumina is widely used in refractory materials, ceramics, electronic substrates, abrasives, and high-end aluminum products. The production process is intelligent, environmentally friendly, and energy-efficient, ensuring high product purity, uniform particle size, and stable activity.

5. Production Line Parameters:

• Applicable Raw Materials: Aluminum hydroxide, bauxite concentrate, alumina hydrate

• Main Products: High-purity alpha alumina powder, ceramic-grade alumina,      refractory-grade alumina, abrasive-grade alumina
