根据煤泥回收工艺的发展过程，总结了我国典型的煤泥回收流程及特点；着重就目前广泛应用的“一段浓缩、一段压滤回收”流程与“两段浓缩、两段回收”新流程从改善产品结构、增加效益；完善浮选工艺，降低灰分；实现清水洗煤和洗水闭路循环几个方面进行了比较与分析，指出“两段浓缩、两段回收”为最佳煤泥回收流程。最后就该流程实施提出了原则意见，强调了新型煤泥回收设备－高频筛的应用。 According to the development process of coal slime recovery process, the typical slime recovery process and characteristics in our country are summarized. The new process of “one section of concentration, one stage of pressure filtration recovery” and “two stages of concentration and two stages of recovery” Improve product structure and increase efficiency; improve the flotation process to reduce ash; to achieve a clean water washing and closed-circuit cycle several aspects were compared and analyzed, pointed out that “two sections of the two recovery” for the best slime recovery process. Finally put forward the principle opinion on the implementation of the process, emphasizing the application of the new coal slime recovery equipment - high-frequency screen.
