摘　　要：针对煤泥重介分选工艺在分选粗煤泥过程中存在的入料不连续、压力达不到分选要求的问题,从煤泥重介流量的调整方法、设备配置和选型、自动控制系统的完善及现场操作等方面提出改进措施,为煤泥重介分选工艺的可靠运行提供了理论指导。According to the problems of the discontinuous feeding and pressure not reach requirement of separation in separation coarser slime by dense medium process,the paper puts forward some improvement measures in aspects of adjusting dense medium flow,the configuration and selection of equipment,perfecting the automatic control system and the operation at the working site,which provide theoretical guidance for the reliability operation of slime separation by dense medium process.
