摘　　要：为进一步提升王庄煤矿选煤厂ZKLX-1100型振动螺旋干法分选机运行质量,以EDEM软件为分析工具,结合动力学分析方法,应用控制变量实验探究不同运行参数下的分选机运行效果,最终确定当分选机振动电机频率35 Hz、垂直振幅2.0 mm、水平扭转振幅0.14°,同时偏心距和电机安装间距分别为95 mm和770 mm时,运行效果最优。从实验结果来看,该优化参数组合在分选质量上显著高于优化前,表明此次参数优化工作取得成功。In order to further improve the operation quality of ZKLX-1100 vibrating spiral dry separator in Wangzhuang Coal Preparation Plant,EDEM software was used as the analysis tool,combined with the dynamic analysis method,and the control variable experiment was used to explore the operation effect of the separator under different operating parameters.Finally,it was determined that when the vibration motor frequency of the separator was 35 Hz,the vertical amplitude was 2.0 mm,the horizontal torsional amplitude was 0.14°,and the eccentricity and motor installation spacing were 95 mm and 770 mm,respectively,the operation effect was the best.From the experimental results,the sorting quality of the optimized parameter combination is significantly higher than that before the optimization,indicating that the parameter optimization work is successful.
