Product Description
Introduction:
The utilization of a dynamic calciner to transform hydroxide into aluminum oxide is gradually becoming a
mature technique. Some domestic large-scale aluminum enterprises have adopted this method as a replacement for
the traditional rotary kiln calcination.
Our company's dynamic calciner can produce no more than 200,000 tons per year. This system includes a heat
source, a calcination main furnace, multistage preheaters, a swirl collector, an electric deduster, a material cooler, a
heat balancer, and a draft fan.
Working principle:
The dehydrated aluminum hydroxide is conveyed by the feeder to the preheater of calciner. Afer two or three
stages of preheating, the surface water of the material evaporates and its temparature increases. Then the material
enters the main furnace of the calciner for high-temperature calcining decomposition. The resulting aluminum
oxide is collected by a collector, cooled in a cooler, and discharged at the discharge gate. The system usually uses
coal gas or natural gas as a heat source. Aluminum hydroxide decomposes into aluminum oxide within seconds.
The entire system is characterized by its small floor area, low energy consumption, stable product quality, and other
features.
Performance features:
Technical specification:
The annual output of the series of products: 5000, 10,000, 30,000, 50,000, 100,000, 150,000, 200,000 tons.

The entire system is characterized by its small floor area, low energy consumption, stable product quality, and other
features.
Performance features:
1. By adopting this method, energy consumption can be reduced by 15-20%.
2. The product's quality is stable and its performance is better than that produced using the traditional method due to sufficient decomposition.
3. Under the same yield, the floor area can be reduced by one third.
4. The operation is highly automated and stable in nature.
Technical specification:
The annual output of the series of products: 5000, 10,000, 30,000, 50,000, 100,000, 150,000, 200,000 tons.
