摘　　要：针对硝基低氮高钾硫型复合肥生产过程中遇到的一系列问题,从生产前期策划、过程控制和转产控制等方面分析讨论生产控制优化措施。生产前期策划主要讨论配方的设计和喷头的大小等;过程控制方面主要讨论温度、水含量、系统返料量设定、产品颜色、残渣率、溶解速率、粒度和洗涤系统的控制等;转产控制方面主要讨论停止加料时间选择、温度、微量元素添加、养分、物料颜色等方面的控制。In response to a series of problems encountered in the production process of nitro low nitrogen and high potassium sulfur compound fertilizer,the production control optimization measures from the aspects of pre-production planning,process control and conversion control are analyzed and discussed.The pre-production planning mainly discusses the design of formulas and the size of nozzles,etc;In terms of process control,the discussion mainly focuses on temperature and moisture,system return settings,product color,residue ratio,dissolution rate,particle size and washing system control;In terms of conversion control,the main considerations include time of stopping material adding,temperature,addition of trace elements,nutrients and material color control.
