When the device works, the motor 9 drives the emulsifying blade component 3 to rotate at a high speed, and materials in a molten state flow into the inner cavity of the spray net 2 and among the six blades 31 from the size mixing tank through the feeding pipe 7. The material is a mixture of urea, potassium sulfate, potassium dihydrogen phosphate, trace elements and mineral humic in a high-temperature molten state according to a certain proportion.
