Abstract

The separation accuracy is hard to be guaranteed when using hydrocyclone to process the blast furnace gas sludge due to its complex components characterized by different sizes and densities. Based on the viewpoint of loose separation, the paper proposed a new type of honeycomb cone combined hydrocyclone and used it for separating iron from the blast furnace gas sludge. Comparative experimental data showed that the comprehensive classification efficiency of particles smaller than 45 μm and the iron grade in the secondary underflow were effectively improved. It verified that the honeycomb cone structure could enhance the loosening degree between particles. Effects of the insertion depth of the vortex finder, cone angle and spigot diameter on the separation performance were further investigated. The response surface methodology of Design-Expert software was used to design and conduct optimization tests to obtain the prediction model of solid phase yield and comprehensive classification efficiency. The results showed that the total solid phase yield of the underflow was 70.70 % and the comprehensive classification efficiency of particles smaller than 45 μm was 50.67 %.
