摘要
研究了高能球磨制备超细铜金粉过程中,助剂加入量、球料比、球磨转速对出料粉体的粒径、松装密度和出料外观的影响。试验表明,在助剂加入量1.5%,球料比10∶1,球磨转速1000/800 r/min条件下球磨150 min,可制得粒径D50为13.83μm,松装密度为1.24 g/cm3的铜金粉。
This paper studies the effects of additives amount,the ratio of ball and raw powder as well as milling rotating speed on the fineness,apparent density,appearance of bronze powder during high energy milling.The result shows that best product can be obtained under the condition of 1.5% additives,10∶ 1 ratio of ball and raw powder,and milling speed of 1000/800 r/min after 150 min milling.And the fineness D50 and apparent density of the powder are 13.83 μm,1.24 g/cm3.
