大武口洗煤厂重介质选煤部分虽已投产多年,但在重介设备和工艺上还存在不少的问题。因此,大武口洗煤厂和开滦煤炭科学研究所合作,对立轮分选机、重介质旋流器、磁选机、脱介筛板和喷水器等各环节进行了分析研究,并采取措施,加以改进。此外,增设了介质比重自动测定与介质桶液位控制装置,介质库和介质输送系统,还完成了耐磨铸石泵的制造。
Although the heavy medium coal preparation section of Dawukou Coal Preparation Plant has been put into operation for many years, there are still many problems in the HM equipment and technology. Therefore, Dawukou Coal Preparation Plant and Kailuan Institute of Coal Science in cooperation, the counter-wheel sorting machine, heavy medium cyclone, magnetic separator, sieve and throwing sieve and other links were analyzed and taken measures to take , To be improved. In addition, the addition of media weight automatic measurement and barrel level control device, media library and media delivery system, but also completed the manufacture of wear-resistant cast-stone pump.
