摘 要: | 在选煤厂设计中计算数质量流程时,所用的浮选入料灰分与分步释放浮选试验的煤样灰分存在差异,介绍了精煤灰分和精煤产率两种修正方法,并对二者进行了比较;同时提出,根据浮沉资料,建立煤炭密度与其灰分的回归方程来确定不同灰分的煤泥密度。

Abstract: | While calculating the flowsheet in design work,the ash content of coal slime usually differs in some extent from data given by the step-release flotation test,two amendment methods introduced,i.e.amending its ash or yield of concentrate,and given are their comparison;concurrently denoted that based on the sink-float data of coal slime,set up a regression equation between ash and density to determine the density of slime of different ash. |
