原煤可选性评定新方法——特定数量效率法

A New Method for Assessment of Coal Washability——the Method on Specific Quantity Efficiency

分析了现行几种煤炭可选性评定方法的适用范围及其局限性 ;提出采用特定条件下的数量效率作为煤炭可选性的评定方法。该方法可以克服现行评定标准存在的各种问题 ,适用于所有原煤在任何分选密度下的可选性评定 ,科学而简便 ,并且不会出现偏差。

The application scope and limitation of several existing assessment methods for coal washability analyzed; an assessment method by quantity efficiency under specific condition proposed. With this method, some problems from washability assessment with existing methods can be overcome; being scientific and simple, it is suitable for washability assessment for all coals at any separation density without deviation.
