Haiwang FZJ series pressurized two product dense medium cyclone has simple structure, easy operation, high passing capacity, high capicty of dry coal, high separation efficiency, multi-angle configuration, imported high aluminum ceramic, long abrasion resistant service life, small feeding pressure and low energy consumption etc. features. So far, the biggest size of this series cyclone is FZJ1600, which has been successively applied on the site already. The two product dense medium cyclone is consisted by the column and cone structure. The materials get fed into the cyclone through the pump after the mixing of mixing barrel and qualified suspension and then the primary coal gets divided into two products: the light product and heavy product by the centrifugal force on the basis of density. The light product is discharged from the concentrated coal pipe by the internal swireling flow and the heavy product is discharged from the gangue port by the external swireling flow.
