Description

Technical Field

[0001] The utility model relates to the technical field of fertilizers, in particular to a stirring device for fertilizer particles. Background Art

[0002] Most nutrients in blended fertilizers exist in a single state. The nutrient ratio can be determined according to soil conditions and crop types, and the release time of fertilizers can be determined according to the growth period of crops, so that fertilizers can play a role when crops need them most. Therefore, the utilization rate of fertilizers is high, waste is small, and pollution to the environment is reduced. In the production process of blended fertilizers, mixing fertilizers evenly is an indispensable process, which directly affects the quality stability of fertilizers. The traditional mixing method is to use a single-screw auger mixer. This type of mixer is a single screw conveying method, which is not easy to flip and mix different parts of fertilizers, and it is easy to have a mixing blind spot. Utility Model Content
