煤泥水流程设计应考虑按最大产率原则,控制适宜的分级粒度,既能最大限度回收低灰粗煤泥,又使高灰细煤泥尽可能多地送入浮选,以取得最大的经济效益。但目前国内的设计有的仅从便于管理出发,无原则地简化煤泥水流程。《选煤设计手册》中推荐的跳汰—浮选型炼焦用煤的工艺流程中的煤泥水流程就是例证,如图1。 Slurry water flow design should consider the principle of maximum yield, control the appropriate grading size, both to maximize the recovery of low ash coarse slime, but also the high ash slime into flotation as much as possible, in order to obtain the maximum economy benefit. However, at present, some domestic designs only proceed from the ease of management and simplify the slime water flow in principle. The recommended jig in the Coal Preparation Design Manual is an example of the slime-water flow in the flotation-type coking coal process, as shown in Figure 1.
