Abstract

The screening of sticky materials is a critical step in mineral processing. This study aims to enhance the screening efficiency (SE) of sticky particles through the optimization of tension combinations in a flip-flow screen (FFS) using the Taguchi experimental method. The FFS was divided into four equal regions along the feed to discharge axis, with the tension in each region considered a factor influencing the screening performance. The Taguchi method was employed to identify the optimal tension combination that maximizes SE. Subsequently, Analysis of variance(ANOVA) was conducted to evaluate the contribution of each region’s tension to the variability in SE. Furthermore, the motion patterns of the particle flow under the optimal tension combination were compared with those under the worst tension combination to elucidate the underlying mechanisms governing the influence of tensions on SE. The experimental results demonstrate that the optimized tension combination significantly improves SE by 9.17%. This optimization approach is not only straightforward to implement but also requires no additional energy input, making it highly advantageous for practical engineering applications.

优化反流筛张力组合，提高筛分效率

粘性物料的筛选是选矿的关键步骤。本研究旨在利用Taguchi实验方法，通过优化翻转流筛（FFS）的张力组合，提高粘性颗粒的筛选效率。将FFS沿进料至出料轴分为四个相等的区域，每个区域的张力作为影响筛分性能的因素。采用田口法确定最大SE的最优张力组合。随后，进行方差分析（ANOVA）来评估每个区域的张力对SE变异性的贡献。此外，比较了最佳张力组合和最差张力组合下颗粒流的运动模式，以阐明张力对SE影响的潜在机制。实验结果表明，优化后的张力组合使SE提高了9.17%。这种优化方法不仅实现简单，而且不需要额外的能量输入，使其在实际工程应用中非常有利。
