摘　　要：利用扫描电子显微镜、震筛机、激光粒度分析仪等仪器,对实验球磨机上制备的锆英粉进行了形貌观察和粒度分析,结果表明:锆英粉呈不规则形状,粒径分布为近似的正态分布,曲线左端细粉分布广,球磨50 h后开始出现"翘尾"现象;锆英粉粒径尺寸随着球磨时间增加下降平缓,达到150 h后,D50为26μm。同雷蒙磨生产的锆英粉相比,球磨机生产的锆英粉堆积密度较大。Some devices including the scanning electron microscope(SEM), vibrating screening machine and laser particle size analyzer are used to observe the morphology and analyze the particle size of zircon powder produced by the sample ball mill, which shows that the morphology of zircon flour presents irregular shape and the particle size distribution is almost normal distribution. The fine particles on the left of the curve are more widely spread. After 50 hours’ milling, the up-tail phenomenon shows up. The size of zircon powder decreases smoothly and slowly with milling time increasing. when it reaches 150 hours, the particle D50 is 26 μm. The bulk density of zircon powder produced by ball mill is higher compared with that produced by Raymond mill.
