分析硝酸铵与硝基复合肥生产相关的基本特性,介绍利用改性硝酸铵氨酸法生产硝基复合肥的工艺流程及生产工艺控制注意事项。通过对配料、造粒、干燥、筛分、冷却、包膜工序指标的严格控制,硝基复合肥成球率可达到90%以上,存放3个月不结块,生产安全平稳运行。
The basic characteristics of ammonium nitrate and nitro compound fertilizer production were analyzed. The technological process of production of nitro compound fertilizer by modified ammonium nitrate and amino acid method and the precautions of production process were introduced. Through the strict control of the ingredients, granulation, drying, screening, cooling, and coating process indicators, the compounding rate of nitro compound fertilizer can reach more than 90%, and can be stored for 3 months without caking and the production runs smoothly and safely.
