摘要
为解决锤片式粉碎机工作效率低、能耗高等问题,对其工作参数进行响应面优化设计.首先进行粉碎机最佳工作参数组合的优化试验,分析主轴速度、回料管直径、喂料速率、筛网孔径及物料含水率对生产率、电耗和粒度的影响规律.然后对试验数据进行响应面设计分析,求解出最优组合并进行试验验证.试验结果表明,粉碎机的最优工作参数组合为:主轴转速2 700 r/min、回料管直径57 mm、喂料速率0.25 kg/s、物料含水率10％和筛网孔径6 mm.对比单因素最优的评价指标,生产率提高4.36％,电耗下降3.23％,粒度减小23.21％.
Abstract
In order to address the issues of low operational efficiency and high energy consumption in the hammer mill,a response surface optimization design was conducted for its operational parameters.Initially,the optimal working parameters of the mill were optimized,and an analysis was performed on the impact of spindle speed,return pipe diameter,feed rate,screen aperture,and material water content on productivity,power consumption,and particle size.Subsequently,a response surface design analysis was carried out using test data to determine and validate the optimal combination through experimentation.Ultimately,the optimum working parameter combination for the crusher is determined as follows:spindle speed at 2 700 r/min,return tube diameter at 57 mm,feed rate at 0.25 kg/s,material water content at 10％,and screen aperture at 6 mm.Compared with the single factor optimal evaluation index,the productivity increased by 4.36％,the power consumption decreased by 3.23％,and particle size reduced by 23.21％.
