Fertilizers are no stranger to farmers in many fields. Large quantities of fertilizers are needed almost every year. The main function of fertilizers is to improve soil properties and improve soil fertility. It is one of the material foundations of agricultural production; however, compound Fertilizers refer to chemical fertilizers containing two or more nutrient elements. Compound fertilizers have the advantages of high nutrient content, few auxiliary components and good physical properties. It is very important for balanced fertilization, improving fertilizer utilization, and promoting high and stable crop yields. effect;
The common granulation processes of compound fertilizer are: drum granulation, disc granulation, spray granulation, high tower granulation, etc. The high-tower melt spinning granulation method consumes high-concentration nitrogen compound fertilizer. This technology sprays the potassium nitrogen-phosphate melt from the top of the granulation tower, and gathers into granules while cooling down in the tower. This is also called melt granulation. In ammonium nitrate consumption enterprises, high tower melting granulation is used. The method of consuming compound fertilizer has the following advantages:
First, it can directly apply concentrated ammonium nitrate solution, eliminating the need for spray granulation process of concentrated ammonium nitrate solution, and the crushing operation of solid ammonium nitrate to make compound fertilizer, which simplifies the consumption process. Ensure safe consumption.
The second is that the melt rotating granulation process fully uses the heat energy of the concentrated ammonium nitrate solution, and the material moisture content is very low, so there is no need for a boring process, which greatly saves energy.
The third is the ability to consume high-nitrogen, high-concentration compound fertilizers. The product particles have a smooth and round appearance, a high percentage of pass, not easy to agglomerate, and easy to dissolve. This ensures that the product has a competitive advantage of strong quality and cost from the consumption technology.
