Alumina calciner is introduced:
By dynamic calcination furnace calcining aluminum hydroxide into alumina is an already gradually mature technology.Large aluminum company has been applied in our country, is to replace the traditional rotary kiln calcination method.
Product introduction:
Is designed by our company research dynamic calcination furnace is suitable for the medium and small type furnace, annual output of 200000 tons the following the system is mainly composed of source, calcination furnace, multistage preheater, vortex, the complement, the electric dust collector, material, heat balance, the cooler wind system and so on
Working principle:
After the dehydration of aluminum hydroxide, the feeder into the calcining kiln preheater, from 2 to 3 preheating process, make the material surface water evaporation, and improve the surface temperature, and then into the calcination furnace high temperature calcination decomposition, after decomposition of the alumina by trap capture, and after cooler, is being exhausted from port discharge.The system generally USES coal gas and natural gas as a heat source.Preheater, vortex, the complement, the electric dust collector, material, heat balance, the cooler wind system, etc.Aluminum hydroxide is decomposed into alumina time only for a few seconds, cover an area of an area small, low energy consumption, stable product quality, etc.
Performance characteristics:
1. The calcining aluminum hydroxide can reduce energy consumption by adopting the method that 15-20%.
2. Due to the decomposition adequately, make the product quality is stable, performance indicators were higher than in traditional way.
3. In the same area can reduce 1/3 under production.
4. A high degree of automation, stable operation.
