通过顺序评价试验结果绘制煤泥可浮性曲线

Drawing of coal slime floatability curves based on sequence evaluation experimental result

根据煤泥顺序评价试验结果,按照煤炭H-R可选性曲线的基本形式,可绘制出煤泥可浮性曲线。介绍了精煤β曲线、尾煤θ曲线、灰分特性λ曲线和精煤灰分±0.5%邻近物产率ε曲线的绘制,并指出煤泥可浮性曲线可较好地反映煤泥的可浮性。

In accordance with basic forms of coal H- R washability curves, a series of coal slime floatability curves can be drawn based on sequence evaluation experiment results; this thesis introduced the drawing method of cumulative float curveβ , cumulative sink curve θ, elementary ash curve λ and clean coal ash ± 0.5 % near-density curve e, which preferably reflected floatability characteristics of coal slime.
