摘要
介绍了离心逆流式超细粉分级机的基本工作原理及特性，采用Ａｌ＿２＿３物料进行了超细粉分级试验。结果表明这种分级机适于超细粉分级并具有较高的分级精度，可与国外同类分级机相比，具有较大的应用前景。
篢he basic principle and characteristics of a centrifugal counter-flow ultrafine dry particleclassifier is intreduced．A classification test of Al_2O_3 is carried out．The results show that this classifieris suitable for the ultrafine particle classification, with higher classification precision compared to simi-lar classifier preduced abroad and promises a bright future in application.
