摘要: 为了降低石墨原材料磨粉粒度波动,提高细粉回收率,进行了响应曲面试验研究。 试验结果表明:磨粉设备的分级频率、主机频率、主机分级交互作用及给料主机交互作用对原料磨 粉的细粉粒度 d50有显著影响,影响程度依次降低,而对于回收率的影响程度为主机频率 > 分级频 率 > 引风频率,因素间的交互作用较弱;优化后的工艺条件为给料频率 9 Hz,主机频率 19.7 Hz,分 级频率 10.5 Hz,引风频率 25 Hz,在此条件下进行试验,得到的细粉粒度 d50为 24.90 μm,回收率为 88.13%,预测值与试验值相近,回归模型具有良好的拟合度和可靠性。

Abstract: In order to reduce the fluctuation of grinding powder particle size of graphite raw materials and improve the recovery rate of fine powder,the response surface test is carried out.The results show that the classification frequency,the main machine frequency,the interaction of main machine classification and the interaction of feeding main machine have a significant effect on the fine powder particle size d50 of raw material grinding powder,and the degree of influence decreases in turn. The degree of influence on the recovery rate is the main machine frequency > classification frequency > induced draft frequency,and the interaction between the factors is weak.The optimized process conditions are as follows that feeding fre‐ quency is 9 Hz,main machine frequency is 19.7 Hz,classification frequency is 10.5 Hz,and induced draft frequency is 25 Hz. Under these conditions,the d50 of fine powder particle size is 24.90 μm,and the recovery rate is 88.13%. The predicted value is close to the experimental value,and the regression model had good fitting degree and reliability.
