郑州工业大学磷复肥研究所和河南力源科技有限公司研制成功了氯化铵、过磷酸钙、氯化钾系复肥造粒剂。它造粒不需加粘土,也不需加硫铵,与粘土或其它粘结剂比较,其成球率可由50％左右提高到90％以上,并且成球快。颗粒表面光滑、均匀、圆整,还可提高生 Zhengzhou Polytechnic Institute of Phosphate Compound Fertilizer Research Institute and Henan Liyuan Technology Co., Ltd. successfully developed ammonium chloride, superphosphate, and potassium chloride compound fertilizer granulators. It granulates without adding clay and does not need to add ammonium sulfate. Compared with clay or other binders, its pelleting rate can be increased from about 50% to more than 90%, and it can be achieved quickly. The particle surface is smooth, even, round and can also improve
