The Performance Prediction Model of W-Shaped Hydrocyclone Based on Experimental Research

Fine particles misclassification in the underflow (UF) of grinding-classification hydrocyclones might result ore over-grinding, leading to both reduced ball mill throughput and metal recovery. In current research, a W-shaped hydrocyclone is proposed, efficiently decrease fine UF. The effects following parameters (including cross-effects) on classification performance were studied experimentally—inlet pressure, apex diameter, vortex finder insertion depth diameter. A mathematical model basis response surface method was established for prediction separation performance. significance factors particle content UF decreased order—vortex diameter > inlet pressure influences different quality effectively order—inlet factor quantity efficiency All influence considered obtain optimal parameter configuration—an 0.14 D, 0.31 an 1.87 0.18 MPa. corresponding −25 μm (C−25) 11.92%, 42.48%, 98.99%.
