| description | Provided is a method of producing high strength shaped alumina by feeding alumina power into an agglomerator having a shaft with mixers able to displace the alumina power along the shaft, spraying a liquid binder onto the alumina power as it is displaced along the shaft to form a shaped alumina, and calcining the shaped alumina. The shaped alumina produced having a loose bulk density of greater than or equal to 1.20 g/ml, a surface area less than 10 m2/g, impurities of less than 5 ppm of individual metals and less than 9 ppm of impurities in total, and/or crush strength of greater than 12,000psi.
种通过以下方式生产高强度成形氧化铝的方法：将氧化铝粉末进料到凝集器中，所述凝集器包括具有混料器的轴，所述混料器能够使氧化铝粉末沿着轴移动，当氧化铝粉末沿着轴移动时，将液体粘合剂喷到氧化铝粉末上以形成成形氧化铝，以及煅烧该成形氧化铝。所生产的成形氧化铝具有大于或等于1.20g/ml的松散堆积密度、小于10m/g的表面积、小于5ppm的单个金属杂质和小于9ppm的总杂质，和/或大于12000psi的压碎强度。 |
