Materials enter the equipment through the feeding pipe. Under the action of centrifugal force, the solid phases will deposit to form a sediment layer on the bowl wall, and the liquid phases will form a liquid ring, successively forming a solid layer and liquid layer inward from the bowl wall. The spiral works continuously to push the solid matters on the bowl wall to the conical end of the bowl and then discharge them out of the equipment through the slag discharging port. And the liquid phases are discharged out through the centripetal pump at the big end of the bowl. 

As the liquid after separation is discharged through the centripetal pump with certain pressure, the mother liquid can be conveyed horizontally for a certain distance, thus to replace a relay pump and save energy. Meanwhile, the possibility of a secondary contact between the tiny droplets and solid matters after the discharge of mother liquid can be completely avoided as they are at different cavities when discharged, so high-degree cleanliness can be ensured, making the product applicable to pharmaceutical and food production, and other fields.
