摘　　要：针对SABC的设计与设备选型不能用传统的经验公式和Bond功指数作为依据的问题,利用先进的JKSimMet模拟软件建立了乌山一期铜钼矿选矿厂SABC碎磨流程的模型,并以现场生产数据为基础进行了模型拟合、参数优化.通过计算得出乌山SABC系统最大处理能力为850 t/h,通过工艺参数优化使SABC碎磨系统生产能力提高了26.7%,同时,碎磨的吨功耗降低2 kW·h以上,年增加经济效益3亿元以上.由此可见,通过JKSimMet软件的模拟和优化可以达到降低能耗和提高产能的目的,这对正在和计划使用SABC半自磨工艺流程的国内矿山有一定的借鉴意义.Realizing the existing issues that traditional empirical equations and Bond crushing work index are no longer fit for the reference basis of SABC circuit design and equipment sizing,an advanced simulation software JKSim Met was applied in this study to model the SABC comminution circuit of Wushan phase I copper-moly concentrator. The model was fitted and optimized based on the operation parameters. According to the simulation results the maximum throughput of Wushan SABC circuit is 850 t / h. The throughput of SABC circuit showed an increase of 26. 7% after optimizing the operational parameters. Meanwhile,the comminution power consumption was decreased more than 2 k W·h per ton,and the economic benefit was increased over 300 million yuan per year. Therefore,by using JKSim Met to simulate and optimize SABC circuit greatly increased the throughput and decreased the energy consumption. This result should shed some light on the domestic mining companies which are applying or plan to apply the SABC comminution circuit.
