摘　　要：介绍一种立式离心磨机,使用该试验机进行不同转速下的破碎实验,利用破碎后的物料粒径质量分布的分形特性建立破碎分形模型,对实验数据进行分析,研究破碎分维数与立磨机转速、破碎率之间的相关性,得到破碎分维数、立磨机转速、破碎率之间的预测模型,并以破碎效果与有用功率为评价指标确定了最优转速值,为立磨机的设计与参数优化提供参考。Using the fractal characteristics of crush after the quality of the material particle size distribution under different rotation speed for new vertical grinding mill,the fractal model for crushing experiments was established.To analyze the experimental data,the regression forecasting model for the crushing fractal dimension was established based on the relationship between the crushing fractal dimension and the vertical grinding mill rotation speed,broken rate. Considering the rotating speed and broken rate for vertical grinding mill,the optimized parameters provide a reference for the optimal design of vertical grinding mill.
