[0002] Compound fertilizer refers to chemical fertilizer containing two or more nutrient elements of nitrogen, phosphorus and potassium. Compound fertilizer has the advantages of high nutrient content, few by-components and good physical properties. It plays a very important role in balanced fertilization, improving fertilizer utilization and promoting high and stable yields of crops.

[0003] Compound fertilizers are usually made into granules, which have low hygroscopicity and are not easy to agglomerate, making them easy to store and apply, especially for mechanized fertilization. The production and processing of compound fertilizers requires a granulator. The compound fertilizer raw materials enter the mold through a spiral feeding system and are squeezed and rubbed, gradually forming granular substances and being cut into specified sizes. The compound fertilizer granules produced by the granulator need to be dried for bagging and storage, and general granulators are often unable to directly dry them when discharging materials. The compound fertilizer granules need to be exported to the drying equipment for drying, which slows down the production efficiency. Therefore, a compound fertilizer production granulation and drying integrated machine is needed. Utility Model Content
