改进工艺提高过滤效果的方法

Method of Raising Filtering Result by Improving Process

采用浓缩闭路循环工艺后，在长时间停车，再行开车的情况下，仍能保持良好的过滤效果、使浮选煤的产量由改造前的２ｔ／ｈ提高到５～７ｔ／ｈ。

The paper introduces the good filting result by using concentrate closed-cycle process while a long stop working and adain starting. The floating coal output raised from 2 t/h to 5-7 t/h and float time reduced.
