China has plenty of alumyte, but 80% of alumyte reserves is of low alumina silica ratio. Rotary kiln is the core equipment in alumina sintering process and its main function is to sinter raw material slurry to produce qualified alumina clinker. Sintering status of rotary kiln synthetically reflects the burning state and material sintering status, and tightly correlates with alumina clinker quality, production, energy consumption as well as equipments status etc. Its automated recognition is important for au...
