As the demand for the production and processing of low grade ores increases, the fine ore yields of various ore industries are increasing. The separation efficiency of the dense medium cyclone is affected by the particle concentration distribution in the gas stream, and according to the horizontal flow separation theory, an inertial separator with a laminar flow field (i.e., uniform particle distribution) exhibits better separation efficiency than an inertial separator with a turbulent flow field (i.e., non-uniform particle distribution), so in order to perform high-efficiency bottom particle size classification, the fluid turbulence should be reduced. The inventor of the present invention has found through research that the conventional dense medium cyclone generally limits the efficient classification of fine particles due to the high entrainment of coarse and fine particles, which requires changing the design concept of the dense medium cyclone and processing the fine particles with minimum disturbance.
