矿山生产能力的不断增长,对矿山充填料浆搅拌设备能力的提高提出了迫切需求。针对金川矿山棒磨砂碎石骨料,开展了150~180 m~3/h高浓度大容量搅拌设备开发与配套工艺研究。首先分析棒磨砂高浓度充填料浆管输特性及搅拌机理;然后针对目前在用的80~100 m~3/h小容量搅拌设备进行放大理论分析,获得150~180 m~3/h大容量高浓度搅拌设备设计参数和技术指标;最后开展与之配套的给料设备和生产工艺研究,获得满足金川矿山棒磨砂骨料和高浓度大容量充填料浆的搅拌设备与充填工艺,并通过半工业和工业充填试验获得成功。该研究为提高金川矿山生产能力奠定了基础,也为目前我国正在建设中的千万吨级大型铁矿料浆充填提供了宝贵经验。
Increasing production capacity of mines poses an urgent need for the improvement of the capacity of mine filling slurry mixing equipment. In view of the Jinchuan Mine Rod Crushed Aggregate, the development of 150 ~ 180 m ~ 3 / h high-concentration high-capacity mixing equipment and its supporting technology were studied. First of all, the characteristics of rod feeding and the stirring mechanism of rod-filled high concentration filler slurry were analyzed. Then, the theoretical analysis of 80 ~ 100 m ~ 3 / h small capacity mixing equipment currently used was carried out to obtain 150 ~ 180 m ~ 3 / h large capacity High concentration mixing equipment design parameters and technical indicators; finally carry out the accompanying feeding equipment and production technology research, access to satisfy Jinchuan mine rod aggregate and high concentration of high-capacity filling slurry mixing equipment and filling process, and through half Industrial and industrial filling tests have been successful. The research lays the foundation for improving the productivity of Jinchuan Mine and also provides valuable experience for slurry filling of 10 million-ton large iron ore currently under construction in our country.
