【摘要】 本研究采用新型ＷＦＪ－１５０型涡轮式空气分级机对高纯度氢氧化铝（０～４０μｍ）粉体原料进行了系统地精细分级试验研究。研究结果得出，调节分级机的风量或风速以及分级轮的转速等工艺参数，可从０～４０μｍ的高纯度氢氧化铝原料中获得０～１５μｍ、５～１５μｍ、０～５μｍ等含量达９９％以上的三种均细物料产品，其牛顿分级效率达８０％以上，分级机的处理能力达到１００ｋｇ／ｈ。更多还原

【Abstract】 On the author’S research,the systematic fine classifying experiment study on high purity of Al (OH)2 powdered material (0～4μm) was carried out by means of WFJ-150 worm air classifier. The results show that through condition the wind rate of classifier and rotation rate of classifier wheel,etc. technological parameters,three evenly fine material of 0～15μm, 5～15μm and 0～5μm whose contents all excede 99 % can be obtained from the highly pure Al (OH)2 material of 0～40μm. The newton classifying rate can reach 80% or above,and the processing capacity can be 100Kg/h.更多还原
