摘　　要：针对包钢宝山矿业原一段旋流器分级效果差、溢流细度粗、运行不稳定、磨损严重等问题,在考察现场磨矿分级工艺的基础上,将原 20°锥结构水力旋流器改为 60°锥结构水力旋流器,并配合调整其他相关工艺及结构参数。改造后的旋流器运行稳定,溢流-200 目细度占 64.07%,沉砂夹细-200 目含量为 12.26%,大幅降低了循环负荷;整体磨矿分级系统效率显著提升,分级质效率高达 51.63%,提升了对细粒级物料的回收效果。In view of the issues of original one-stage hydrocyclone in Baoshan Mining of Baotou Steel such as poor classification effects,coarse overflow grain,unstable operation and serious wear etc.,on the basis of field grinding and classifying process,original 20°taper-structured hydrocyclone was replaced with 60°taper-structured hydrocyclone,and other technical and structural parameters were altered also.The upgraded hydrocyclone operated stably,the fineness of-200 mesh in overflow accounted for 64.07%,the fineness of-200 mesh in grit accounted for 12.26%,which greatly reduced the cyclic load.The productivity of whole grinding and classifying system remarkably increased with the quality efficiency of classification reaching 51.63%,thus the recovery effects of fine-grained material were enhanced.
