我厂生产氧化铝的生料浆,系采用喷入法以高压机械雾化喷枪送入回转窑内。长期以来,料浆的计量和喂料量的稳定,被认为是个老大难问题。由于我厂采用的料浆碱浓度高,流动性差,料浆中石子、铁屑、纤维等夹杂物 I plant alumina raw slurry production, Department of injection method using high-pressure mechanical spray gun into the rotary kiln. For a long time, the measurement of slurry and feed stability, is considered a chronic problem. Due to the high concentration of slurry alkali used in our plant, poor fluidity, inclusions in the slurry such as gravel, iron filings and fibers
