采用射流分级的方法对粗钨粉末进行预处理。实验结果表明,射流分级预处理同样可以有效的处理粗钨粉粉末,最终得到粒径分布范围非常窄的钨粉。
The coarse tungsten powder is pretreated by jet classification method. The experimental results show that the jet pretreatment can also effectively treat coarse tungsten powder, and finally obtain tungsten powder with a very narrow particle size distribution range.
