The invention relates to a dense medium coal dressing device, in particular to an un-pressurized feeding dense medium cyclone with large diameter capable of separating three products. The invention is characterized in that: the axis of a first section of the cyclone is parallel with the axis of a second section of the cyclone, and the angle between the axis and the horizontal plane is 15 to 30 DEG; the first section of the cyclone is connected with the second section of the cyclone through a connecting hose, and the angle between the connecting hose and the horizontal plane is 0 to 90 DEG. The invention has the advantages that: firstly, the pressure loss when the material enters into the second section of the cyclone from the first section of the cyclone is reduced, pressure conditions of the separation of the second section of the cyclone are guaranteed, meanwhile the material entering into the second section of the cyclone can also be stabilized; secondly, the turbulent flow is reduced ...
