马鞍山矿山研究院和首钢大石河选厂共同进行的选厂自动化试验研究,经过几年的努力,现已初获成果,在选矿厂三系统关键部位磨机-分级机组实现了一次球磨闭环自动控制、二次旋流器自动控制。这项自动控制技术目前已基本成熟,可以进行推广使用。大石河选矿厂一次球磨闭环自动控制试验研究是1974年开始的,1976年自动控制检测仪 Maanshan Mining Research Institute and Shougang Dashihe selection plant jointly carried out the election of plant automation test research, after several years of efforts, has now achieved initial results, the key parts of the three-plant mill dressing - grading unit to achieve a ball mill closed loop automatic control , Secondary cyclone automatic control. This automatic control technology has basically been mature and can be promoted and used. Dashihe beneficiation mill ball mill closed-loop automatic control test study began in 1974, 1976 automatic control tester
