Alumina Calcining Production Line (α-alumina Production Line)

Alumina calcining production line (α-alumina production line)

Alumina calcining line is a set of high temperature calcining system for the production of high purity α-alumina (Al₂O₃). The production line adopts rotary kiln calcination process to convert aluminum hydroxide or aluminum hydrate into stable α-aluminum oxide under high temperature environment of 1200℃~1400℃. The produced α-alumina is widely used in refractory materials, ceramics, electronic substrates, abrasive materials, high-end aluminum products and other fields. The production process is intelligent, environmental protection and energy saving to ensure high product purity, uniform particles and stable activity.

Applicable raw materials: aluminum hydroxide, bauxite concentrate, aluminum oxide hydrate

Finished products: high purity α-alumina powder, ceramic grade alumina, refractory grade alumina, grinding grade alumina

Production capacity: Annual output 5000-100000 tons (can be customized)
