Numerical analysis and experimental research on the influence of column structure on the classification performance of hydrocyclone

Year: 2025

Type: article

Abstract: A cylinder section serves as a pre-separation area for hydrocyclone classification and a necessary area for fine particles to enter an overflow. Therefore, exploring the influences of cylinder structures on the flow and particle aggregation characteristics inside hydrocyclones is important. In a parabolic cylinder structure, the highest-pressure conversion efficiency was 89.96 %. Experimental comparisons show that the quality efficiency of the parabolic column structure cyclone is 49.56 %, which is 17.63 % higher than that of the conventional feed body, alongside a reduction by 29.70 % of the −20μm particles content in the underflow and an increment by 14.77 % of the −20μm particles content in the overflow, respectively compared to the conventional hydrocyclone.
