Brief Introduction: |
The process of aluminum hydroxide calcination using dynamic calciner has gradually matured. It has been widely applied to aluminum companies in China, and gradually replaces the traditional rotary kiln calcination method.
The dynamic calciner designed and manufactured by our company is suitable for medium and small furnaces with production capacity under 200 000 tons per year. This system is mainly consists of heat source, main calciner, multi-level pre-heaters, rotational flow trap, electric dust collector, material cooler, thermal balancer and fan system etc.
Performance Features: |
♦energy consumption can reduce by 15-20% when using this process to calcinate aluminum hydroxide
♦sufficient decomposition makes the quality of products is stable, and performance indexes are better than those of traditional methods
♦floor space occupied reduces by 1/3 with the same production capacity
♦highly automated, stable operation
Operational Principle: |
The dehydrated aluminum hydroxide is fed into calciner via feeder. Surface water of material has been evaporated under 2-3 level preheating process, and the surface temperature of the material has been increased, and then the material is fed into the main calciner for high temperature calcination and decomposition, the decomposed aluminum oxide is collected by the trap, and finally discharged by the cooler from the dumpling port, after cooling
This system commonly uses gas and natural gas as the heat source. It is only takes a few seconds for aluminum hydroxide to decompose into aluminum oxide.
Technical Specifications: |
Annual production capacity of a single set of this series model is 5 000 tons, 10 000 tons, 30 000 tons, 50 000 tons, 100 000 tons, 150 000 tons or 200 000 tons.
