摘 要:凡口铅锌矿新建一座5000 t/d的单系列选矿厂代替3个平行生产系列的磨矿浮选厂,以提升自动化智能水平和矿山经济效益。为此,选矿厂设备OEM PLC采用了Profibus-DP通讯接口,工业自动化系统(DCS)选用西门子PCS7过程控制系统,选矿专家系统引进美卓矿机OCS自适应控制专家系统软件包,选矿厂信息化系统采用自主研发,工业视频监视和液晶显示系统采用自主设计与组装,计量与检测选用先进的在线检测仪器与仪表。通过对上述系统、仪器与仪表的集成设计,选矿厂实现了自动化生产与管理,生产铅精矿、锌精矿、高铁硫精矿,取消铅锌混合精矿,提高了产品附加值,减少生产人员258人,每年增加营业收入7970万元,净利润5385万元,税后增量投资财务内部收益率16.40%,信息化取得了良好的经济效益。In order to improve the standard of intelligent automatical control and the economic benefits of the mine,a new 5000 t/d concentrator with one single series is build to replace the concentrator withgrinding and flotation system in Fankou Lead-zinc Mine,which is divided into threeparallel production series.Profibus-DP communication interface is used in OEM PLC facility.SIEMENS PCS7 process control system is used in industrial automation system(DCS)and Metso OCS adaptive control expert system software package is also added into the mineral processing expert system.The information-based system of the concentrator adopted independent research and development,the industrial video monitoring and LCD display system used independent design and assembly,while the measurement and detection employed advanced online detection instruments and meters.Automatic production and management in mineral processing plant are achieved after the application of the integrated design of these systems,instruments and meters,meanwhile,the lead concentrate,the zinc concentrate and the concentrate contained high grade of sulphur areproduced,the lead-zinc mixed concentrate is cancelled,the added value of products has increased,as well as production personnels are reduced 258 persons.The annual operating incomes and net profits of the concentrator are upby 79.70 million yuan and 53.85 million yuan,respectively.The after-tax incremental investment financial internal rate of return is 16.40%,which has achieved good economic benefits.
