分选磷矿用重介质旋流器的研究与实践

Research and practice of dense media for separation of phosphate ores

通过对旋流器的结构和工艺参数的研究及改进,提出了分选磷矿用重介质旋流器。采用两段式结构,通过调整重介旋流器的锥比、安装角度,并将一段旋流器由圆筒型变为一定角度的锥型,实现了高密度磷矿石的有效分选。采用Fluent数值模拟软件对新型分选磷矿用重介质旋流器与传统重介质旋流器进行了对比研究,且介绍了新型磷矿旋流器的分选工艺和应用情况。

Dense media cyclone is introduced by research and im- provement on cyclone in terms of structure and process data. Effective separation of phosphate ores of high density is accomplished by adopting two-stage structure, adjusting ratio of cone and mounting angle in heavy media cyclone and changing stage 1 cyclone from cylinder type to cone type with certain angle. Study was carried out of comparison of new model dense media cyclone for separation of phos-phate and traditional dense media cyclone. The separation technology and its application of new model phosphate cyclone is presented.
