充气式浮选机和机械搅拌式浮选机串联使用在赵楼选煤厂的生产实践

Practice of operation of pneumatic and subaeration flotation machines in tandem at Zhaolou Coal Washery

介绍了赵楼选煤厂的浮选系统,分析了入浮煤泥的性质,比较了KHD型充气式浮选机和XJM-S型机械搅拌式浮选机的设备性能和应用情况,阐述了两者串联的浮选工艺流程。生产工艺指标表明:串联浮选工艺应用效果良好,使浮选精煤得到了有效的分选回收。

Following an introduction to the flotation system in current use at Zhaolou Coal Washery, the paper makes an analysis of the property of the feed coal and a comparison of the performance of the KHD pneumatic flotation machine and the XJM -S subaeration version. Then, the paper goes to elaborate on the flotation process with the abovementioned 2 types of machines working in series. As indicated by actu- al operating performance, the flotation process works remarkably well, making it possible for the washery to effectively increase the recovery of combustible matters and yield of concentrate.
