[0002] In the process of producing fertilizers, it is necessary to granulate the fertilizers. Although the existing fertilizer granulators can meet the basic needs of granulating the fertilizers, after the raw materials are squeezed out of the round hole, when the raw materials are cut by the cutting structure, because the cutting structure used is only connected to the rotating structure in the middle, and other parts of the cutting structure, such as the side ends, are not provided with auxiliary support structures, there is a defect that the cutting structure is easily bent and deformed, which not only affects the service life of the cutting structure, but also affects the effect of cutting the raw materials, which will bring great inconvenience to people's use.
