摘要
可选性曲线是原煤分选的一个重要理论参考,对选煤有着重要的指导意义。曲线绘制的准确程度将直接影响实际分选效果,而绘制的便捷与否则关乎原煤的生产效率,故而高效准确地绘制可选性曲线是原煤分选前的重要一步。文章总结了目前有关可选性曲线绘制的方法原理,分析了各类方法的优势,并提出了思考与展望,以为原煤的高效分选和系统的学习研究相关知识提供基础的参考。
Washability curve as an important theoretical reference for coal separation is of vital guiding significance for coal preparation operations. The accuracy of the curve plotted and whether the curve can be drafted conveniently or not have a direct bearing on coal separation effect and efficiency. Therefore, plotting the washability curves in a highly efficient and accurate manner constitutes an important link ahead of coal washing process. The paper makes a summary of the currently available plotting methods and the principles applied by each method, as well as an analysis of their respective special features. Finally, the co-author presents some viewpoints on the methods that should be developed for plotting the washability curves in the future, in a bid to provide a fundamental reference for effecting high-efficiency coal separation and making systematic learning and study of related knowledge.
