江苏绿陵化工有限公司研究用碳酸氢铵代替部分尿素生产高浓度复混肥,生产原理主要是提高物料的pH值,达到磷酸一铵的最大溶解度,提高物料粘性,少用或不用尿素,以氯化铵补充氮源。1工艺流程(见图1)2主要工艺指标(1)碳酸氢铵用量60 kg/t肥;(2)造粒机内物料温度60~65℃,出口粒径1~4
Jiangsu Luling Chemical Co., Ltd. research with ammonium bicarbonate instead of part of the urea production of high-concentration compound fertilizer, the production principle is to increase the pH of the material to reach the maximum solubility of monoammonium phosphate to improve the material viscosity, with or without urea to Ammonium chloride supplements the nitrogen source. 1 process (see Figure 1) 2 main process indicators (1) ammonium bicarbonate dosage of 60 kg / t fat; (2) pelletizer material temperature 60 ~ 65 ℃, export size 1 ~ 4
