摘　　要：在山西临县某炼焦煤选煤厂的改造中,原设计为不脱泥无压三产品旋流器分选+煤泥浮选的选煤工艺,改造设计遵循煤泥减量化,粗煤泥分级分选、细煤泥高效分选的原则,采用原煤干法预排矸+脱泥无压三产品旋流器分选+粗煤泥三产品干扰床分选+细煤泥主再浮选的选煤工艺,改造方案最大程度地提高了精煤的产率,降低了介耗、药剂消耗,增加了经济效益。In the design process of Lin Xian Shanxi coal preparation plant,the original process is no desliming pressureless three products cyclone+slime flotation,with slime reduction,slime grade separation,slime efficient separation transformation principle,the new process is block coal dry separation+desliming pressureless three products cyclone+coarse coal slime three products teeter bed separation+fine coal slime two-stage floating,maximize the cleaned coal yield,reduced medium consumption,flotation reagents consumption,increased economic benefits.
