1991年3月12日至14日,冶金部科技司在梅山铁矿召开了梅山选厂浮选过程自动控制、自动加球机技术鉴定会。梅山选厂浮选过程自动控制。它是“七五”国家科技攻关项目——“红矿选矿技术”的“选矿自控技术研究”课题的子专题。由马鞍山矿山研究院和上海梅山冶金公司铁矿共同负责完成。该题从梅山选厂实际需要出发,研究内容包括浮选液位自动调节、加药自动调节
From March 12 to March 14, 1991, the Science and Technology Department of the Ministry of Metallurgical Affairs held the automatic control of the flotation process of Meishan Concentrator at the Meishan Iron Mine, and the automatic ball-adding machine technology appraisal meeting was held. Meishan factory flotation process automatic control. It is the “Seventh Five-Year” national science and technology project - “red ore beneficiation technology” of “beneficiation control technology research” sub-topic. By the Ma On Shan Institute of Mining and Shanghai Meishan Metallurgical Iron Mine jointly responsible for the completion. The title from Meishan dressing plant actually needs to start, the research includes automatic adjustment of the floatation level, dosing automatic adjustment
