Role of chemical fertilizer

The fertilizer can be absorbed quickly and efficiently. The nutrients in chemical fertilizer are mainly inorganic and do not need microbial transformation and decomposition. After the application of soil nutrients, they will be absorbed by the roots of crops.

For example, chemical nitrogen fertilizer can be completely released within 3 to 15 days after being applied to the soil, which can quickly meet the needs of crops in the growth stage of plants. Chemical fertilizer can also be applied through irrigation or even leaf coating, which greatly improves the nutrient absorption efficiency of crops.

Fertilizer itself is harmless. Chemical fertilizer has high nutrient content and low impurity. Urea, for example, contains 46% nitrogen. Nitrogen is a nutrient for crops. The rest is mainly Co. When applied to the soil, it is released back into the atmosphere again and is harmless. In addition, it contains about 1% of water and about 1% of urine.

It is strictly controlled below 1.5%. It is harmless to crops and can be decomposed in soil and used by crops and microorganisms. Other phosphate fertilizers, potash fertilizers and trace elements are extracted from minerals, and the basic components are harmless.

Chemical fertilizer improves soil fertility. The nutrient deficiency of common farmland is different. Application of chemical fertilizer can increase crop biomass, increase surface coverage and reduce soil erosion. In addition, the application of chemical fertilizer has increased crop yield, providing a broad space for the development of urban construction, transportation, industry and commerce.

According to the different soil conditions and crop needs, the development of suitable high-efficiency fertilizer products and the scientific and rational application of chemical fertilizer have great potential for agricultural development.

NPK fertilizer production

How to avoid fertilizer clumps in NPK fertilizer production

Fertilizer blocking problems usually occur in the process of fertilizer processing, storage and transportation, and are caused by the absorption, dissolution, evaporation and recrystallization of fertilizer particles. In this process, a crystal bridge is formed, causing small particles to form large particles and clump.
So how to avoid the fertilizer clumps generated by NPK fertilization equipment?

1. Choose the right raw material.

Fertilizer production of raw materials, such as ammonium salts, phosphates, trace element salts, potassium salts, etc., mostly contain crystalline water, easy to absorb water, such as ammonium sulfate, phosphate, trace elements easy to reunite, insoluble in water. Urea is prone to extract water and clumps with trace element salts.

Choose raw materials that are not easy to clump and produce fertilizer that does not clump. For example, fertilizers with humic acid as the main raw material and amino acids as the main raw materials are not easy to clump. Also, try to keep the material dry when selecting it.

2. When producing NPK fertilizer, the water content and packaging temperature of the fertilizer should be reduced and the appropriate production time should be selected.

Fertilizer production is generally non-closed. During the production process, the greater the air humidity, the easier the fertilizer is to absorb moisture clumps. Fertilizer production avoids the rainy season and concentrates on fertilizer production on dry days. In the fertilizer production process, the raw material is heated by dryer, so that the water content of fertilizer is controlled at 0.6%, prolonging the cooling time of fertilizer, reducing the packing temperature, making the fertilizer not easy to clump.

3. Add anti-clumping agent to reduce the physical chemical reaction between NPK fertilizer particles.

The higher the room temperature, the easier it is to dissolve. In general, raw materials dissolve in their own crystalline water and cause clumps. Adding talcum powder, humic acid and other non-clumping powders can also be added some surfactants to prevent clumps.

4. Reduce the height of the fertilizer stacking and storage pressure.
The greater the external pressure of fertilizer, the easier it is for the crystal to clump in contact with the crystal, and the smaller the external pressure, the more difficult it is to clump.

5. The NPK fertilizer can be screened with a screening machine to further improve the uniformity of fertilizer particles.
NPK fertilizer particle size is not uniform, particle spacing is small, contact area is large, easy to reunite. If the pressure strength of fertilizer particles is low, deformation and breakage are easily occurred during packaging, transportation and storage, increasing the contact area between the particles, which can also lead to fertilizer clumps.

If the fertilizer plant uses NPK fertilizer production line to produce a large amount of fertilizer, can be used for two screening machines to obtain suitable fertilizer particles.

6. Production of NPK fertilizer particles.

Because of the small contact area between circular particles, it is not easy to crystallize the clumps. Therefore, the granulation of nitrogen and phosphorus potassium fertilizer is beneficial to the storage, transportation and fertilization of fertilizer.

When using roller granulators to produce NPK compound fertilizer particles, the dryer is not used, but the raw materials for the production of fertilizer must have good adhesion.

When producing NPK compounding particles with a disc granulator (or drum granulator), it must be dried and cooled.
