摘　　要：优化柔性风选机的关键工艺参数,可提高梗签剔除率,从而提高产品纯净度。通过对设备的主要工艺参数进行显著性分析,确定主要影响参数后,进行全因子试验,应用响应曲面法进行分析找到最佳控制模型,并应用模型进行实际生产验证后确定最佳参数组合。结果表明,柔性风选机的3个主要参数(工艺风速、风门开度和针辊频率)中,工艺风速和风门开度对梗签剔除率有显著影响,且当工艺风速19.0m/s、风门开度11.5%时,即可达到控制目标(梗签剔除率稳定控制在90%内)。Optimized the key technical parameters of the flexible winnowing machine,to improve the sign out rate and the product purity.By the significant analysis on the main process parameters of equipment,determined the main parameters which influence the whole factor test,and the application of response surface method was used to find the best control model.And applied the model to the actual production after validation,to determine the best parameter combination.Results：Among the three main parameters of flexible winnowing machine technology,for the wind speed,throttle opening and the frequency of needle roller,the wind speed and the throttle opening has a significant influence on the sign out rate.When the wind speed was 19.0 m/s,the throttle opening was 11.5%,the target control could be achieved.When the wind speed of flexible winnowing machine was controlledin 19.0 m/s,and the opening of the throttle was controlled in 11.5%,the sign out rate can be controlled within the 90%target,stable.
