The clarity of the liquid phase after clarification of 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 of the drum settling zone. The average residence time of the liquid phase in the drum settling zone. Similarly, the solid phase moisture content of the centrifuge after dewatering is determined by two factors: the effective centrifugal force acting on the solid phase of the drum dewatering zone. The average residence time of the solid phase in the drum dewatering 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. Under normal circumstances, firstly, the drum rotation speed range is set roughly for the separated material, and then the differential rotation speed and the overflow plate are adjusted according to the separation condition of the centrifuge to obtain a better separation effect. The adjustment of the differential speed and the overflow plate and the liquid phase clarity and the solid phase moisture generally have the following regularity: a small differential speed will lower the solid phase moisture content, but the liquid phase clarity will decrease. A large differential speed will increase the clarity of the liquid phase, but the solid phase moisture content will increase. A smaller inner diameter overflow plate will increase the clarity of the liquid phase, but the solid phase moisture content will increase. A larger inner diameter overflow plate will lower the solid phase moisture content, but the liquid phase clarity will decrease. Therefore, when the liquid phase clarity is dominant and the solid phase moisture content is secondary, the deeper tank depth should be used, and the differential speed should not be too small. When the solid phase dryness is dominant and the liquid phase clarity is secondary, a shallower pool depth and a smaller differential speed should be used. The above is the main factor affecting the liquid phase clarity of the decanter centrifuge. If you need to buy better centrifuge equipment, consult.
