无压入料轻产物有压分选三产品重介质旋流器应用效果分析

Analysis of application of new type gravity-fed three-product heavy medium cyclone with the functionality of pressure-separated lower density materials

为解决无压入料三产品重介质旋流器精煤带矸的问题,研制出无压入料轻产物有压分选三产品重介质旋流器。介绍了新型重介质旋流器的结构、工作原理、技术特点、技术参数,并分析了其在现场的应用效果。该旋流器一段可能偏差在0.03~0.04之间,二段可能偏差在0.05~0.07之间,分选精度高,使用效果好,有效解决了精煤带矸的问题,推广应用前景广阔。

In order to solve problem of reject carried into clean coal from gravity- fed three- product heavy medium cyclone,new type gravity- fed three- product heavy medium cyclone with the functionality of pressure- separated lower density materials is developed. Presented the features of this cyclone,such as structure,working principle,technical features and parameters,and then analyzed its application in coal preparation plant. Being features of mean probable error between 0. 03 and 0. 04 in first separation stage and that between 0. 05 and 0. 07 in second separation stage,it is valid to solve above problem,with high accuracy.
