摘　　要：道清选煤厂在浮选精煤脱水系统增设了LWZ900×1800型沉降过滤式离心脱水机,提高了选煤厂入洗能力和精煤产率;但由于离心机入料的平均粒径偏细,与同类离心机的工艺指标对比后发现,其脱水产物水分高、固体产率低,而对入料进行掺粗是解决这一问题的重要措施。A LWZ900×1800 sedimentation-filtration dewatering centrifuge additionally installed in dewatering system for flotation concentrate for increasing its capacity and concentrate yield at Daoqing Coal Preparation Plant;due to finer size of feed material,in comparison with similar centrifuge,its operation result being higher moisture content in dewatered product and less yield of recovered solid;admixture of coarse particulate material into the feed being the important measure for its solution.
