Description

Technical Field

[0001] The utility model relates to the technical field of compound fertilizers, in particular to granulating equipment for compound fertilizer production. Background Art

[0002] Compound fertilizer refers to a fertilizer containing two or more nutrients. 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. Compound fertilizer is usually in granular form and is generally manufactured by granulating equipment for compound fertilizer production.

[0003] Granulating equipment for compound fertilizer production generally mixes raw materials and water in proportion and then conveys them to the inside of the squeezing roller device. The raw materials are squeezed into particle plates by special particle squeezing rollers, and then the particle plates are crushed by a crushing device to form granular fertilizers. When the raw materials are conveyed to the squeezing rollers, some of the raw materials will adhere to the squeezing rollers. As the moisture on the surface of the raw materials evaporates, the raw materials will become dry and mix with the next wave of raw materials entering the surface of the squeezing rollers. The raw materials with evaporated moisture are mixed with the new raw materials entering the device, and after being squeezed together, they will affect the quality of the produced compound fertilizer particles.
