摘要
介绍了玉溪选煤厂入洗原煤性质、块煤系统存在的问题,比较了国内当前主要块煤排矸设备的优缺点;针对玉溪选煤厂块煤的实际情况,确定采用重介质浅槽分选机分选块煤的工艺流程,改造后选煤厂分选效率提高,经济效益明显增加。
This paper introduces the raw coal properties and the problems in the lump coal system of Yuxi Coal Preparation Plant, and compares the advantages and disadvantages of the current main lump coal processing equipment in China. Based on the actual situation of lump coal in Yuxi Coal Preparation Plant, the heavy media vessel process is selected to separate lump coal. The separation effect of heavy media vessel for processing lump coal is analyzed.The cleaning efficiency is improved and the economic benefit of the coal preparation plant is obviously increased.
