三产品重介旋流器—煤泥两段直接浮选工艺的应用

Application of the process with three-product HM cyclone and two-stage slime flotation

辛置选煤厂应用脱泥有压三产品重介旋流器—煤泥两段直接浮选工艺对一车间进行了技术改造,生产实践证明,该工艺在分选极难选、易泥化炼焦煤时,具有分选精度较高、技术指标先进的良好效果。

The First Workshop of Xinzhi Coal Preparation Plant was converted by employing a process of three-product HM cyclone by pressurized feeding of de-slimed coal and two-stage slime flotation; its production practice denoted that, for coking coal with difficult washability and easily degraded slime, good performance achieved in regard of high separation selectivity and advanced technical index.
