摘　　要：对铜冶炼渣进行了高压辊磨开路试验、边料循环试验、闭路粉磨试验以及与颚式破碎机产品的磨矿对比实验,并对各产品进行了粒度分析。结果表明,铜冶炼渣经高压辊磨处理后,产品中细粒级含量明显增加,可磨度提高约36个百分点,高压辊磨有利于提高铜冶炼渣的磨矿效率和选矿技术指标。High pressure grinding roll(HPGR)was used to comminute a copper smelting slag.An open⁃circuit test,edge⁃product cycling test and closed⁃circuit ball mill test were carried out using HPGR.The particle size of various products were measured,and the grinding results after HPGR were compared with those obtained after jaw crushing.The results show that after copper smelting slag is processed using HPGR and ball mill,the fine particle fraction of the products increases obviously,and the grindability increases by about 36 percentage point.It can be concluded that HPGR approach favors upgrading of grinding efficiency and beneficiation index in processing copper smelting slag.
