变转速球磨对粉料加工质量的影响

THE EFFECT OF BALL_MILLING WITH VARIABLE ROTATIONAL SPEED ON THE PROCESSING QUALITY OF POWDER

实验室和工业应用试验结果表明，变转速球磨方法不仅能较大幅度地提高球磨效率，而且能对粉料加工质量产生明显的影响．利用粒度分布测定仪、ＸＲＤ、ＦＴＩＲ、ＰＭ及ＳＥＭ等仪器分析结果表明，在相同条件下，变转速球磨所得粉料，其细颗粒含量较多，颗粒分布范围较窄，粒度较均匀，颗粒棱角较少、较圆滑，这有利于提高陶瓷产品的质量．

Tests in laboratory and industry have shown that ball_milling with variable rotational speed can raise the efficiency of ball_milling by a big margin and improve the processing quality of the powders. The experiment of granular metric analysis, XRD, FTIR, PM, and SEM has proved that the slurry made by ball_milling with variable rotational speed contains more fine grains; its grain_size is distributed narrower and its edges and corners are blunter than those at regular speed. So ball_milling with variable rotational speed is a useful method for improving powder quality.
