【摘要】：為提高再生微粉的利用率,對再生微粉進(jìn)行機(jī)械力粉磨處理。研究了超微氣流粉碎和振動球磨對再生微粉性能的影響。采用激光粒度分析儀、XRD、SEM和壓力試驗機(jī)對再生微粉的粒徑分布、物相構(gòu)型、微觀形貌和砂漿的抗壓強度進(jìn)行表征,并按國標(biāo)對再生微粉活性指數(shù)進(jìn)行檢測。結(jié)果表明:氣流粉碎機(jī)粉磨的再生微粉的粒徑分布范圍窄、粒形規(guī)整、填充效果好、活性高;利用氣流粉碎機(jī)對再生微粉進(jìn)行處理,提高了再生微粉的利用率和利用范圍。
[Abstract]:In order to improve the utilization rate of regenerated powder, mechanical grinding treatment was carried out. The effects of ultrafine air grinding and vibration ball milling on the properties of regenerated powder were studied. The particle size distribution, phase configuration, microstructure and compressive strength of the regenerated powder were characterized by XRDX SEM and pressure tester, and the activity index of the regenerated powder was measured according to the national standard. The results show that the particle size distribution range is narrow, the particle shape is regular, the filling effect is good and the activity is high, and the utilization ratio and utilization range of the regenerated micro-powder are improved by using the airflow pulverizer to treat the regenerated micro-powder.
