摘　　要：为了解决任家庄选煤厂二期重介主洗系统分选效果差、中煤带煤量大的问题,从介质入料压力稳定性、介质入料压力大小和旋流器结构三个方面入手进行了优化改造,从而使中煤带煤量得到明显下降,解决了精煤损失严重的问题。In order to solve problem caused by bad separation effect and much clean coal carried in mid- dlings in second phase heavy medium separation system of Renjiazhuang coal preparation plant, the opti- mization and modification on this system is made in forms of medium feed pressure and its stability, cy- clone structure. The application shows that content of clean coal carried in middlings is significantly re- duced, and then loss of clean coal reaches minimum.
