Structure of three-product dense medium cyclone set

The invention provides a structure of a three-product dense medium cyclone group. The structure comprises a first-section cyclone, a second-section cyclone, a ball head structure, a material guide pipe, a material outlet and a material inlet, a discharge hole is formed in the bottom of the first-section cyclone; a feeding hole is formed in the top of the second-section cyclone; a ball head structure is arranged between the discharge port and the feed port; the ball head structure comprises a feeding ball head pipe and a discharging ball head pipe; the feeding ball head pipe is arranged at the top of the discharging ball head pipe; the top of the feeding ball head pipe is fixed to the bottom of the discharging opening through a flange. The ball head structure of the three-product dense medium cyclone set is improved, so that materials can smoothly pass through the ball head structure, and the three-product dense medium cyclone set has the advantages that the materials are not easy to collide and crack when pas
