原煤的可选性曲线研究

Study of raw coal washability curve

原煤的可选性曲线对选煤厂煤质的分析和选煤厂的设计有着决定性作用,所以,用最简洁最快捷的办法绘制出可选性曲线对于工作的完成有着重要的作用。因此介绍了如何运用AutoCAD、Excel、VBA实现自动绘制可选性曲线。

Washability curve of raw coal plays a decisive role in analysis of raw coal property and design of coal preparation plants. Hence, plotting the said curves in a most simplified and rapid manner is of vital importance to the execution of the above mentioned two tasks. An introduction is made in the paper to the way to realize automatic plotting of washability curves with the use of Auto CAD, Excel and VBA.
