What are the advantages and disadvantages of NPK fertilizer granulation process

fertilizer granulator Nov 22, 2023

The common granulation processes of compound fertilizer include drum granulation, disc granulation, spray granulation and tower granulation. Each granulation process has certain advantages.
1. Drum granulator is also called drum granulator. Drum granulator is the most widely used equipment in compound fertilizer production. The main working mode is wet granulation. Through a certain amount of water or steam, the basic fertilizer can be fully chemically reacted after being humidified in the cylinder. Under a certain liquid phase condition, with the help of the rotary movement of the cylinder, the extrusion force between the material particles can be produced to agglomerate into pellets.
2. Spray granulation.
Spraying mostly refers to urea spraying, which is to spray the melted urea to the compound fertilizer granulation unit, so as to reduce the urea crushing link. If the urea plant is connected with the urea pipe, the cost will be saved. The fertilizer dissolves quickly, and most of them are high nitrogen formula with nitrogen more than 20.

3. The most basic disc granulation
The technological principle of disc granulation is that all raw materials are mixed and put into disc granulation, and the disc is rotated to make the materials agglomerate into balls. Disc granulation is characterized by simple equipment, less investment and fast start. The disadvantage of disc granulation is that it is only suitable for small-scale production with low efficiency. The daily output is only tens of tons, and the formula is limited. It needs viscous materials and is only suitable for low concentration granulation.
4. Ammoniation granulation
Ammoniation granulation compound fertilizer is produced by ammoniation and secondary dechlorination granulation process. The principle is that potassium chloride and sulfuric acid are added to the reaction tank for heating and reacting under certain conditions. The HCl gas escaped can be absorbed by water to produce hydrochloric acid of certain concentration. The generated potassium bisulfate is mixed with dilute phosphoric acid to form mixed acid. The mixed acid and synthetic ammonia are reacted in a tubular reactor in proportion to produce compound fertilizer slurry, which is directly sprayed into a drum npk fertilizer granulator to produce sulfur based compound fertilizer with a certain proportion of nitrogen, phosphorus and potassium. It has the characteristics of uniform granulation, bright color, stable quality, sufficient nutrients, easy to dissolve and be absorbed by crops, especially as seed fertilizer.
5. Tower granulation
The high tower is to melt the raw material of compound fertilizer at high temperature or turn it into a mixture of molten slurry, which is scattered from high altitude. When it is scattered, the surface tension becomes spherical. Re screening. The particles are not easy to agglomerate because they have little water in the process of high temperature. The materials are fully mixed and the particles are crystal clear. Good looks. The reaction material needs high purity, high concentration formula, and the proportion of urea is relatively high.

Organic fertilizer is mainly produced by plant and animal waste, which provides adequate nutrition for crops and plays a key role in improving soil structure. But compared with powdery organic fertilizer, what does granular organic fertilizer mean? Next, the organic fertilizer granulator machine Huaqiang heavy industry will answer for you. First of all, from the perspective of structure, powdery organic fertilizer is relatively light. When in use, it is easy to blow off the fertilizer in case of wind, causing unnecessary loss. Organic fertilizer particles have certain quality and are easier to apply fertilizer. In addition, the transportation of fertilizer is also an experiment of fertilizer. Powdery fertilizer is easy to caking in the process of transportation, which can not guarantee the quality of organic fertilizer. Because in the production of organic fertilizer must add some inorganic components, if it is powder fertilizer, it will further aggravate its moisture absorption and caking.

The disc granulator takes the motor as the power to drive the inclined disc to rotate. The internal scraper prevents the material from sticking to the bottom of the disc.

The adhesion degree of different raw materials is different, so when choosing organic fertilizer raw materials, we should pay attention to the collocation of raw materials with different adhesion degree, which can improve the success rate of granulation and granulation quality. In special cases, we can use an appropriate amount of adhesive.
2. The grasp of moisture. The water content of raw materials is one of the main factors affecting the success rate of granulation and granulation quality. If the water content is too low, the difficulty coefficient of granulation will increase; if the water content is too high, the viscosity of raw materials will increase, the diameter of particles is easy to be too large, and the difficulty of drying behind will increase. Therefore, the moisture content of raw materials should be moderate. According to the basic data, the moisture content of raw materials for disc granulation should be between 25% – 30%.
