在复混肥表面喷涂尿素溶液生产高氮复混肥,以满足农作物在苗期对氮的需求。1 工艺方案简介在50kt/a复混肥生产线上,不用改变团粒法的工艺流程,只是将出干燥机的物料筛分,再经过皮带计量秤计量后进入冷却机,同时控制系统将其信号反馈给微机,微机根据反馈的信息自动发指令到
Spraying the urea solution on the surface of the compound fertilizer to produce high-nitrogen compound fertilizer to meet the demand for nitrogen at the seedling stage. 1 Process Introduction In 50kt / a compound fertilizer production line, do not change the process of the pellet method, only the material out of the dryer screen, and then through the belt weighing scale into the cooling machine, while the control system to signal feedback To the computer, the computer automatically sends instructions according to the feedback
