摘要
通过正交实验法,研究了高纯氧化铝粉体气流粉碎工艺过程中,分级轮频率、气流压力及给料频率对氧化铝粒度的影响。结果表明,气流粉碎能够有效提高粉体的分散性,降低粉体的粒度,使粉体的分布范围由原来的0～60μm降至0～6μm。改变分级轮频率、气流压力及给料频率对氧化铝粒度产生了一定影响。分级轮频率70. 0Hz、气压0. 8 MPa、给料频率4. 0 Hz条件下,得到的高纯氧化铝粉体具有良好的分散性和粒度分布。
Orthogonal experimental method was used to study the effect of grading wheel frequency,gas pressure and feed frequency on alumina particle size in the process of high-purity alumina powder mill.The results show that the air-flow pulverization can effectively improve the dispersibility of the powder and reduce the particle size of the powder,so that the powder's distribution range decrease from the original 0-60μm to 0-6μm.The high-purity alumina powder obtained by the grading wheel frequency of 70.0 Hz,atmospheric pressure of 0.8 MPa and feeding frequency of 4.0 Hz has good dispersibility and particle size distribution.
