| 摘 要： | 在对牛蒡微粉加工中影响因素进行单因素试验及分析的基础上，采用二次回归正交试验设计，研究了球磨机转速、研磨时间、粉碎介质填充率和物料填充率等因素对粉体粒度、单位粉体耗能等指标的影响，建立了各指标与试验因子间关系的回归数学模型。利用多目标非线性优化方法，确定了优化指标的工艺参数组合为：行星球磨机转速为272 r/min，研磨时间为85 min，介质填充率为12%，被粉碎物料填充率为13%，此时最低耗电量为0.002 kW·h/g。研究所确立的牛蒡微粉加工优化工艺参数对牛蒡微粉加工具有指导意义。

| Abstract: | Based on single factor experiment and results analysis of influences on burdock fine pulverizing, quadratic regression orthogonal experiment was carried out for studying effect of ball mill rotation speed, pulverizing time, medium filling rate and material filling rate on pulverizing criteria such as powder granularity and unit powder energy consumption, and regression mathematical models describing relations between experimental factors and pulverizing criteria were established. Using multi-goal non-linear optimizing method, optimal combination of technological parameters for burdock fine pulverizing was determined with ball mill rotation speed 272 r/min, pulverizing time 85 min, material filling rate 13% and medium filling rate 12%, which achieved minimum unit powder energy consumption 0.002 kW·h/g. The optimal technological parameters have an instructional significance for burdock fine pulverizing with ball mill. |
