摘　　要：对巴基斯坦某铜矿高压辊磨终粉磨工艺与常规破碎-球磨工艺进行流程设计、设备选型、投资估算与技术经济比较分析。结果表明,高压辊磨终粉磨工艺流程较长、设备数量较多、设备总安装功率较大,高压辊磨终粉磨工艺建设投资比常规破碎-球磨工艺高1087.4万美元。经营成本方面高压辊磨终粉磨工艺能耗较大,并没有体现出节能的优势,但由于没有钢球和磨机衬板的消耗而导致该工艺选矿单位总成本较低。高压辊磨终粉磨工艺年营业收入和利润总额比常规破碎-球磨工艺分别高439.87万美元和460.12万美元。从长期来看,该铜矿采用高压辊磨终粉磨工艺能够产生更好的经济效益,具有较好的工业应用价值。Process design,equipment selection,investment estimate and technical and economic comparison between HPGR final grinding and traditional crushing-ball mill process were conducted for a copper mine in Pakistan.The results indicate that HPGR final grinding process is longer,with more equipments and installation power comparing to traditional crushing-ball mill process.The investment of HPGR final grinding process is 10874 thousand dollar higher than that of traditional crushing-ball mill process.Energy consumption of HPGR final grinding process is higher than that of traditional crushing-ball mill process,but the operating cost of HPGR final grinding process lower,because no steel ball and ball mill liner consumed.Annual operating revenue and net profit of HPGR final grinding process are 4398.7 and 4601.2 thousand dollar higher than that of traditional crushing-ball mill process.In the long run,HPGR final grinding process can generate more better economic benefits for this copper mine,which has better industrial application value.
