摘要
论述了微粉煤的摩擦电选技术和高梯度磁选技术的基本原理和发展应用现状,对影响其分选效果的因素和当前存在的主要问题进行了探讨,指出优先发展微粉煤干法分选技术的工业化应用将有效地减轻燃煤污染并取得显著的社会经济效益。
The basic principles of the triboelectricity beneficiation and high gradient magnetic separation technology,as well as its current status of development and usage,were presented.Also its effect factors of separation efficiency and its current main problems were discussed.It is pointed that pollution induced by coal combustion would be effectively alleviated through the industrial application of fine coal dry separation technology,and remarkable social and economical benefit would be gained at the same time.
