Due to the size difference between coarse particles and fine particles, they are subjected to different centrifugal forces, centripetal buoyancy, fluid drag, etc. Under the action of centrifugal sedimentation, most of the coarse particles are discharged through the bottom flow port of the cyclone, and most of the fine particles are discharged from the overflow pipe, thereby achieving the purpose of separation and classification.
