铝土矿生料浆烘干与烧结特性的试验研究

在试验室条件下,参照国外研究成果,结合我国碱石灰烧结法氧化铝生产实际,从生料浆黏度变化规律、生料浆烘干过程及生料浆烧结特性等方面进行了试验.研究试验结果表明:真钙比的变化对同一水分下生料浆黏度的影响不明显,当生料将水分＜38％时,生料浆水分和生料浆温度升高对生料浆黏度值影响较大；气态悬浮干燥器中料浆烘干温度应不低于60...

Test study on the Raw Slurry Baking and Sintering Feature of Aluminate Sodium Sintered Material

Combining with alumina production practice by the alkali-lime sintering process,referring to foreign study achievements,the author studied the law of the viscosity,baking process and sintering feature of the raw slurry in the laboratory conditions.The test results showed that the true calcium ratio change had no effect on the viscosity of the raw slurry at the same moisture,but when the raw slurry moisture was less than 38%,its moisture and temperature increasing had a large effect on its viscosity.The slur...
