Problems solved by technology

[0002] The high-tower granulation process is an advanced compound fertilizer production process at present. The compound fertilizer produced has the characteristics of uniform nutrient, low water content, high particle strength and stable product quality. The disadvantage is that due to the limitation of process characteristics, the product usually only contains nitrogen. , Phosphorus, Potassium a large number of inorganic elements, can not add materials that increase the function of the product
For example: due to the high temperature of the pulping process on the tower, it is not conducive to the survival of microorganisms, therefore, microorganisms cannot be added in the high tower granulation process
The above problems lead to the single function of high-tower fertilizer products, which are difficult to adapt to different soil conditions, and cannot effectively improve the utilization rate of fertilizer nutrients, improve crop quality and improve soil structure.

preparation example Construction

[0023] A method for preparing a synergistic high tower urea-based fertilizer comprises the following steps:

[0024] (1) Add the metered urea into the melting tank, the temperature of the melting tank is controlled at 120°C-125°C, and the melted urea solution overflows to the primary mixing tank;

[0025] (2) Add the measured potassium chloride into the primary mixing tank and mix it evenly with the urea solution. The temperature of the primary mixing tank is controlled at 110°C-115°C, and the mixed molten material overflows to the secondary mixing tank ;

[0026] (3) In the secondary mixing tank, add monoammonium phosphate, high molecular polymer and regulator by metering, and mix with the molten material for less than 5 minutes to obtain a mixed molten slurry. The temperature of the secondary mixing tank is controlled at 100°C-105 ℃;

[0027] (4) After the mixed molten slurry is emulsified by the emulsifier, the differential granulator is used to complete the spray granula...
