| Abstract: | In this paper, a technical line for production of sandy alumina which is concernd with development of Chinese aluminum industry is put forward. From the policy of feeding “fine materials" to a blast furnace, the demand of both aluminum electrolyting and purification of electrolytic gas for sandy alumina is proved. The reformation of processing technology of alumina plant is discussed. The information about which Cyclone Fine Screen (CFS) 450 is applied for improvement of alumina quality by ALUMAR Corporation in Brasil is introduced. |
