选煤总厂用于煤泥水澄清的主要设备浓缩机共有2台,分别是φ18 m 高效浓缩机和φ30m耙式浓缩机,当φ18 m 浓缩机的底流与φ30m 浓缩机的底流浓度达到300g/L 后,将二者先放到φ30m浓缩机搅拌桶中,再用打料泵运输到煤泥厂进行压滤处理,生产中发现现有的这套系统存在很多问题,严重影响了洗煤的正常生产。1 存在问题 There are two main equipment thickeners for the clarification of slime water at the coal preparation plant. They are φ18 m high efficiency concentrator and φ30 m rake thickener. When the underflow of φ18 m thickener and the underflow concentration of φ30 m thickener reach 300 g / L After the first two put into φ30m thickener mixing drum, and then hit the pump material transported to the slime plant filter processing, found in the production of the existing system there are many problems that seriously affect the normal production of coal washing . 1 there is a problem
