icult to achieve automatic control of the thickener that the limitations of the initial design and frequent fluctuations in ore nature. By optimizing the transformation of the thickener automatic pressure control system,the reliability of the automatic control thickener have improved, the use of consumables have avoided, the workload and costs have reduced, and the desired effect have achieved. This paper focuses on the transformation of pressure control.РKeywords:Thickener;Manometer;The automatic control;Optimization;TransformationР作者联系方式Р作者姓名Р联系电话РE-mail地址Р样刊邮寄地址Р邮政编码Р石自信Р18766690332Р380625514@Р山东省烟台市莱州市三山岛金矿新立选矿车间Р261400Р自荐审稿专家Р专家姓名Р联系电话РE-mail地址Р工作单位Р职务/职称Р王庆凯Р18601097965РWang_qk@Р北京矿冶研究总院Р高级工程师Р孙卫东Р13791154156РSwd701205@Р山东黄金矿业(莱州)有限公司三山岛金矿Р高级工程师Р邹国斌Р15801556849РZou_gb@Р北京矿冶研究总院Р中级工程师
