综述了静电分离技术在各个领域的应用。通过对静电分选机的分类，从带电方式和分选设备两个方面介绍了静电分选机的最新进展，并展望了静电分选机的发展趋势。详细介绍了电晕荷电和感应荷电分选机的原理和实用结构。基本上，这些充电和分离方法适用于电导率差异大的材料。摩擦起电已被用来充电的材料具有很小的差异，在电导率。这是从塑料混合物中分离可重复使用的塑料材料和从煤粉中分离矿物质或灰分的情况。摩擦荷电是一项关键技术，介绍了用于选煤的摩擦荷电器的种类。作为一种实用的分离器的例子，介绍了近年来从原材料中回收铜和树脂的突出技术。
ABSTRACT The applications of the electrostatic separation technique employed in the various field was overviewed. By classifying the electrostatic separators with the charging method and with the kind of sorting equipment, recent progress in the electrostatic separators was presented and also future trend was discussed. Principle and practical structure of the separator employing corona charging and induction charging was described in detail. Basically these charging and separation methods are applied to the materials with large difference in conductivities. Triboelectrification has been employed to charge the materials with little difference in conductivities. This is the case of the separation of reusable plastic material from plastic mixture and of minerals or ash contents from coal powder. Triboelectric charging is a key technique and the variety of a tribocharger for coal cleaning was presented. As an example of a practical separator, recent prominent recycling technology of copper and resin from pri...
