| Abstract: | On the problems of caking and dusting common to compound fertilizer plants an analysis is made of the causes, and a systematic consideration is given to the characteristics of the raw materials used, the chemical reaction mechanism, the granulation process, the cooling process, and the special anti-caking equipment. The technologies are developed for high-temperature granulation, highefficiency drying, pre-cooling and scattered piling for deep-drying, combination of hot screening and cold screening, and high-efficiency anti-caking coating, with special accessory equipment, and a series of appropriate measures are proposed, thereby solving effectively the caking and dusting problems of high-nitrogen compound fertilizers. |
