| Abstract (English): | To address the low classification efficiency of hydrocyclones in a concentrator and overcome the limitations of single-parameter optimization, this study systematically investigated the coupling effects of operating parameters, such as feed flow rate, feed concentration, and feed fineness, and structural parameters, including spigot diameter and vortex finder insertion depth. The effects of each factor on classification efficiency were determined through single-factor experiments, and an L16 (45) orthogonal experimental design was then adopted to investigate the synergistic effects of structural and operating parameters. The results show that the order of influence of each factor on classification efficiency is: feed fineness −38 μm proportion > spigot diameter > feed flow rate > feed concentration > vortex finder insertion depth. The optimal parameter combination is a feed flow rate of 152 m³/h, feed concentration of 39 %, feed fineness of 37 % (−38 μm fraction), spigot diameter of 16 mm, and vortex finder insertion depth of 105 mm, resulting in a hydrocyclone classification efficiency of 66.27 %, which is 22.86 percentage points higher than that of the original process. This research provides a theoretical basis and practical reference for the optimization of grinding and classification processes in similar concentrators. [ABSTRACT FROM AUTHOR] |
| Abstract (Chinese): | 针对某选矿厂旋流器分级效率偏低的问题, 为突破单一参数优化局限, 系统开展了给矿 流量、给矿浓度、给矿细度等操作参数与沉砂嘴直径、溢流管插入深度等结构参数的多场耦合作用 机制研究。通过单因素试验明确了各因素对分级效率的影响规律, 采用 L16 (45) 正交实验设计, 揭示了结构参数与操作参数的协同调控效应。结果表明: 各因素对分级效率影响的顺序为给矿细 度−38 μ m 占比>沉砂嘴直径>给矿流量>给矿浓度>溢流管插入深度, 最优参数组合为给矿流量 152 m³/h 、给矿浓度 39% 、给矿细度−38 μ m 占比 37% 、沉砂嘴直径 16 mm、溢流管插入深度 105 mm, 旋流器分级效率达 66.27%, 较原工艺提升 22.86 百分点。研究成果可为同类选矿厂磨矿分级工艺 优化提供理论依据和实践参考。 [ABSTRACT FROM AUTHOR] |
