摘　　要：近年来 ,我国的超细粉碎与超细分级技术有很大的发展 ,但在发展过程中存在着一些问题。超细粉体涉及的行业众多 ,但对其粒度的分类至今国内尚无定论。通过调研 ,分析了目前国内超细粉碎设备的现状。对超细粉体分级技术中的干法分级和湿法分级作了比较全面的介绍 。Although great progress has been made in the development of ultra-fine grinding and classification technology in recent years,there are some problems which need to be solved.Despite that the ultra-fine grinding technology concerns with many industries,the classification for its particle size remains uncertain.Through study and market survey,the current status of ultra-fine grinding equipment has been analyzed,and the wet and dry classification technology for ultra-fine materials has been overall introduced.The proposal for development of ultra-fine grinding and classification technology has been brought forward.
