The core principle of a horizontal screw centrifuge is based on centrifugal sedimentation. During operation, the mixture enters the drum through the feed pipe. Under the centrifugal force generated by the high-speed rotation (typically thousands of revolutions per minute), denser solid particles are thrown against the inner wall of the drum, forming a sediment layer; less dense liquids are discharged through channels in the drum, achieving solid-liquid separation.
Its key structures include the drum, screw conveyor, differential gear, and power system: the drum provides the centrifugal field, the screw conveyor pushes the sediment to the discharge port, and the differential gear controls the separation effect and discharge efficiency by adjusting the speed difference between the drum and the screw.
