7 detailed process to make compound fertilizer

Process design description of NPK fertilizer production line:
1. Batch processing:
Electronic batching or disc batching.
2. Crushing process:
The mixed fertilizer proportioned according to the design requirements is sent to the raw material crusher for raw material crushing. The purpose is to crush various raw materials to a certain fineness. Basically, the particle size of raw materials is less than 1mm, which is conducive to the material in the granulator. Roll inside to meet the standard ball.

3. Granulation process:
The crushed mixture is conveyed to the fertilizer granulator through the conveyor. The liquid phase provided by the slurry or water in the extrusion granulator makes use of the centrifugal force brought by the rotation of the fertilizer granulator to turn the material into organic fertilizer. At present, it is better to use the disc granulator to produce organic fertilizer. The granulation rate of disc granulator can reach more than 90%, but the table output is low.
4. Drying process:
The granular materials are transported to the rotary three drum dryer through the conveyor. The hot blast stove is set at the inlet of the dryer to provide heat for the drying of materials in the dryer and evaporate the water in the formed materials into water. The steam is introduced into the dust collection chamber through the fan to remove dust. After the material enters the dryer, the liquid phase of the material is high and the ball strength is low. In order to ensure the sphericity of the material, we used it in the design of the dryer.
5. Cooling process:
The moisture content of materials after drying generally can not meet the water content requirements of organic fertilizer. Cooling in the cooler is very important for the NPK fertilizer manufacturing process.
6. Screening process:
The cooled organic fertilizer still has a certain temperature. After the organic fertilizer material enters the screening machine, the organic fertilizer material is roughly classified, and the screened fine powder is directly returned to the granulator for granulation. After screening, the screened coarse material is crushed by the return chain crusher, and then returned to the granulator for re granulation. The finished product is directly sent to the silo of the packaging scale. On the other hand, compound fertilizer materials are also used for screening projects. Cooling engineering plays a certain role in reducing temperature and preventing material caking.
7. Packaging process:
The coated finished organic fertilizer enters the silo of the packaging scale, automatically counts according to the set quantity, then puts it into the packaging bag, and then through the automatic sewing system, the sewn compound fertilizer can be stacked in the silo. Warehouse. In principle, the height of each stack shall not exceed 8 bags and the height shall not exceed 10 bags. The ground must be damp proof.

The advantages of making organic fertilizer from traditional Chinese medicine residue are:

1. Increase crop yield and improve the quality of agricultural products. In addition to nitrogen, phosphorus, potassium and other nutritional components, fermented drug residue also contains a variety of sugars, amino acids and other substances, which not only provide nutrients for crop growth, but also promote microbial activities and maintain micro ecological balance. Soil.

2. Fermentation residue fertilizer contains a large number of beneficial microorganisms. After use, it can improve soil, improve crop root absorption and prevent diseases.

3. Secondary utilization, turning waste into treasure, reducing the use cost of chemical fertilizer and avoiding environmental pollution.

The organic content of traditional Chinese medicine residue is often more than 70%. According to the latest organic fertilizer standard, the total nutrient content of traditional Chinese medicine residue is usually not up to standard.

If the traditional Chinese medicine residue fermentation is used as raw material to produce organic fertilizer, nitrogen and phosphorus can be added to the traditional Chinese medicine residue. Chemical fertilizer or potassium fertilizer, or binary or ternary compound fertilizer, and then add biological fermentation bacteria to fully ferment and crush, which is the standard organic fertilizer. Different residues have different fermentation ratios.

Add the drug residue into the organic matter with high crude protein content such as livestock and poultry feces, bone meal and animal corpses, and add biological fermentation bacteria. Stack it with organic fertilizer dumper, stir it evenly and ferment for several days. During the fermentation process, the temperature rises continuously.

When the temperature reaches above 45 ℃, turn it over every 2 ~ 3 days, and the temperature of the stockpile can be maintained between 50 ~ 70 ℃. When the temperature drops slowly, stop turning the pile and let it stand for about a week to basically complete the decomposition and fermentation. After decomposition, it is crushed by the crushing device to obtain powdered organic fertilizer.

Nowadays, compared with powdered organic fertilizer, the best-selling organic fertilizer in the market is relatively easy to store and spread, and is favored by customers. If granular fertilizer is to be made, the powdered fertilizer shall be granulated by a fertilizer granulator to obtain granular fertilizer. Then it is dried, cooled, screened, and finally packaged for storage.

How to make bio fertilizer step by step?

Bio organic fertilizer refers to the fertilizer processed by microbial fermentation, decomposition and harmless treatment with livestock manure, straw, agricultural and sideline products, food processing waste, organic waste and urban sludge as raw materials.

Role of bio organic fertilizer:

(1) Increase crop yield and improve crop quality.
(2) Improve soil fertility and soil physical and chemical properties
(3) Regulating microbial flora and improving soil micro ecosystem
(4) Activate insoluble compounds and improve soil supply.
(5) Improve soil ecology and reduce the occurrence of diseases and pests

Production process and technology of biological fertilizer:

1. Production process of bio organic fertilizer

The bio organic fertilizer production enterprise registered with the Ministry of agriculture is mainly engaged in the production of microbial fertilizer. In the process of fermentation production, trough stacking fermentation and other fermentation methods, such as flat fermentation, are used.

The method, fermentation tank fermentation method and closed warehouse fermentation method are also used in production. In the process of fermentation and decomposition, the adjustment of material moisture, carbon nitrogen ratio and temperature and the use of decomposition agent are the key to the production process, especially the application of microbial agent directly affects the degree and maturity of circular fermentation.

The decomposed substance basically realizes the harmlessness of the product, which is conducive to the survival of the functional bacteria added in the post-treatment process.

2. Production technology

In the post-treatment of fermentation materials, most enterprises will add functional bacteria for compound molding. The dosage form of the product is mainly powder, but there are also fertilizer granulators for granulation.

The granular product overcomes the disadvantages of poor appearance and low grade of powdered products, improves the commodity of products, but also increases the production cost of enterprises, and has a certain impact on the survival of effective bacteria.

How organic fertilizer is made?

The organic fertilizer production line from sx organic machines is designed for the production of organic fertilizer granulator. In the process of organic fertilizer production, different types of fertilizer equipment are equipped to complete the production process. Here, we introduce the characteristics of organic fertilizer.

In the process of organic fertilizer production, organic fertilizer can be divided into powder organic fertilizer and granular organic fertilizer.

Among them, the technology of powdery organic fertilizer is relatively simple

1. Check the ingredients of your raw materials (such as plant ash, furfural residue, humic acid, etc.) to understand the accurate nutritional composition and proportion of each raw material, which plays an important role in the production of organic fertilizer;

2. The general production process of organic fertilizer requires the content of nitrogen, phosphorus and organic fertilizer granulator or disc granulator or roller granulator; the production process of organic fertilizer requires the content of nitrogen, phosphorus and potassium to be more than 4% and the content of organic matter to be more than 30%. So organic fertilizer can be mixed, crushed and packaged.

In addition, fertilizer equipment such as drum granulator, organic fertilizer granulator, disc granulator or roller granulator is required for organic fertilizer granules. The production of organic fertilizer requires the same raw materials as powder fertilizer, but after adding binder (bentonite or green palygorskite), the final particles need to be dried by rotary dryer.

Organic fertilizer production line

There is also an organic fertilizer with livestock manure, domestic waste and plant straw as the main raw materials.

The production process of the organic fertilizer is as follows: raw material drying, crushing, fermentation, mixing (mixed with chemical fertilizer). And other organic or inorganic substances, so that nitrogen, phosphorus, potassium content into particles (or not into particles, powder) and then packaging.
