The difference between high tower granulation, spray granulation and drum granulation

Solid urea or ammonium nitrate (ammonium nitrate phosphorus, etc.) is heated and melted to become a molten liquid. The corresponding phosphate fertilizer, potassium fertilizer, and other elements are added to the molten liquid. The additives are made into a mixed slurry and sprayed from the top of the granulation tower, so that the surface tension when it is scattered in the tower is cooled and agglomerated into granules and becomes spherical.
Advantages of high tower granulation:
1. Directly use the solution, eliminating the crushing operation and simplifying the production process
2. Make full use of the thermal energy of the solution, the moisture content of the material is very low, and there is no need for a drying process, which greatly saves energy consumption.
3. High-nitrogen, high-concentration compound fertilizers can be produced. The surface of the product particles is smooth and round, the qualified rate is very high, it is not easy to agglomerate, and it is easy to dissolve.ent elements. One application of compound fertilizer can supply at least two or more main nutrient elements to crops at the same time.
