Abstract: Introduced the single structure three-product dense medium cyclone structural characteristics and working principle.On the basis of the single structure three-product dense medium cyclone theoretical studies, completion of the single structure three-product dense medium cyclone structure designed and exploratory research.The results showed: the single structure three product dense medium cyclone can achieve separation three different products in the single cylinder cone structural.However,The optimal structural parameters of the single structure three-product dense medium cyclone need to be researched.
