Which is the best, ammoniation granulation, spraying granulation, and tower granulation?

<> process is different: the tower granulation imitation is to spray the nitrate, phosphorus and potassium melt from the top of the granulation tower, so that it can be agglomerated into granules while falling and cooling in the tower, and the spraying granulation uses evaporation to produce fine particles from the solution or slurry, and the slurry is first sprayed into mist-like micro-droplets, and the solid matter in the droplets will gather into particles when the water evaporates.

The products are different: the surface of the tower granulation fertilizer is smooth and round, not easy to agglomerate, easy to dissolve, and the spraying granulation fertilizer is approximately spherical and has a certain particle size.

First, the process is different

1. Tower granulation: the nitrate, phosphorus and potassium melt is sprayed from the top of the granulation tower, so that it can be cooled and aggregated into granules during the landing process in the tower, which is also known as the "melt granulation method".

2. Spraying granulation: with the help of evaporation, fine particles are prepared from the solution or slurry, mainly including spraying and drying, the slurry is first sprayed into mist-like micro-droplets, and when the water is evaporated by hot air, the solid matter in the droplets will gather into dry anti-excitation particles.

Second, the products are different

1. Tower granulation: the surface of the fertilizer is smooth and round, the pass rate is high, it is not easy to agglomerate, and it is easy to dissolve.

2. Spraying granulation: the fertilizer is approximately spherical and has a certain particle size distribution.

Third, the fertilizer effect is not the same as lead

1. Tower granulation: The nitrogen content in the fertilizer is generally more than 20%, the phosphorus content is about 15%, and the biuret content is close.

2. Spraying granulation: The nitrogen content in the fertilizer is generally about 12%, and the water-soluble phosphorus is low.

Spraying granulation: It is a process in which the water in the slurry (mixture, solution and solute) (the general term for the liquid that can be vaporized) is sprayed into a device, and the water in the slurry is vaporized and separated by heating and pumping method, and the remaining solids that will not be vaporized (under certain conditions) form granules. For example, the final manufacturing process of ammonium phosphate granular fertilizer.

Ammoniation granulation: Ammoniation granulation compound fertilizer is the production process of ammoniation and secondary dechlorination granulation, and the principle is to convert potassium chloride.

It is heated with sulfuric acid and reacted with sulfuric acid in the reaction tank under certain conditions, and the escaped HCl gas can be absorbed by water to obtain a certain concentration of hydrochloric acid, and the generated potassium bisulfate is mixed with dilute phosphoric acid to form mixed acid. The mixed acid and synthetic ammonia are reacted in proportion to the tubular reactor to generate compound fertilizer slurry and directly spray it into the rotary drum granulator to generate a certain proportion of nitrogen, phosphorus and potassium sulfur-based compound fertilizer. It has the characteristics of uniform granulation, bright color, stable quality, sufficient nutrients, easy dissolution and absorption by crops, especially the seed fertilizer is relatively safe for seeds.

It is suitable for all kinds of soil and wheat, corn, melons and fruits, peanuts, vegetables, beans, flowers, fruit trees and other crops and cash crops.

It is suitable for base fertilizer, seed fertilizer, top dressing, seed fertilizer and flushing.

The spraying granulation is better, you can go to Linshu to see, there are many fertilizer factories.
