The main factors of liquid phase clarity of decanter centrifuge

- Dec 19, 2020-

The clarity of the liquid phase after clarification in the decanter centrifuge (hereinafter referred to as the centrifuge) is determined by the following two factors: the effective centrifugal force acting on the liquid phase in the settling zone of the drum. The average residence time of the liquid phase in the settling zone of the drum. The same , The moisture content of the solid phase after the centrifuge dehydration is also determined by two factors: the effective centrifugal force acting on the solid phase in the drum dehydration zone. The average residence time of the solid phase in the drum dehydration zone. By adjusting the operating state of the centrifuge, The above factors can be controlled within a certain range to obtain a better separation effect.

1.Under normal circumstances, first set the drum speed range for the separated materials, and then adjust the differential speed and overflow plate according to the separation of the centrifuge to obtain a better separation effect.

2. The adjustment of the differential speed and the overflow plate and the clarity of the liquid phase and the humidity of the solid phase generally have the following rules: a smaller differential speed will reduce the solid phase moisture content, but the liquid phase clarity will decrease.

3.A larger differential speed will increase the clarity of the liquid phase, but the moisture content of the solid phase will increase.

4. An overflow plate with a smaller inner diameter will increase the clarity of the liquid phase, but the solid phase moisture content will increase. An overflow plate with a larger inner diameter will reduce the solid phase moisture content, but the liquid phase clarity will decrease.

5. Therefore, when the clarity of the liquid phase is the main and the moisture content of the solid phase is inferior, a deeper liquid pool depth should be used, and the differential speed should not be too small.

6.When the dryness of the solid phase is the main and the clarity of the liquid phase is the second, a shallower liquid pool depth and a smaller differential speed should be used.
