fertilizer production line

The other 75% nutrients in chicken, sheep and pig feed were excreted with feces, including nitrogen, phosphorus, potassium, organic matter, amino acid, protein and so on. A series of treatments in the organic fertilizer manufacturing process turn manure into organic fertilizer. How can organic fertilizer equipment achieve rapid fermentation and deodorization to produce finished products? What are the advantages of this process over ordinary fermentation?

Fermentation technology of organic fertilizer

1. The energy consumption of compost turning machine is low.

Fecal composting fermentation process can use biological heat to evaporate a large amount of water, low energy consumption, save coal, electricity, labor intensity, can better control the fermentation humidity, reduce the loss of effective substances.

2. Organic fertilizer equipment fermentation environment pollution is small.

Closed equipment is used in compost tipper to strengthen the controllability of factory production and reduce the exposure of mosquito and fly parasitism source. This can effectively control environmental pollution and produce high-quality organic fertilizer under the premise of ensuring the environment.

3. The processing time of organic fertilizer fermentation equipment is short.

First, the factory fermentation process is used to inoculate high-efficiency active bacteria, so that the microorganisms can quickly form dominant bacteria, shorten the fermentation time, and accelerate the deodorization. Generally, deodorization can be completed within 2 to 3 days. At the same time, the turning of the turning machine increases the oxygen required for microbial activities and speeds up composting. Under normal natural conditions, open-air composting often takes several months.

Only by understanding the advantages and functions of the equipment can it play its role better. We provide organic fertilizer manufacturing process and NPK fertilizer manufacturing process to ensure the steady improvement of agricultural production efficiency.

Fertilizer Equipment Manufacturer will introduce you to the production process and process of fertilized fertilizer in large fertilizer plants. Friends who want to build a fertilizer plant can refer to it.
Production process of organic fertilizer

1.After mixed fermentation of bacteria and raw materials, the composting machine is used in the fermentation process. Fermented compost can provide nutrients and improve soil properties, especially for sandy soil, clay and salinized soil.

2.The rotten raw materials are crushed and screened, and then arrive at the deep processing workshop through the elevator.

3.The fertilizer is mixed by the raw material mixer and then enters the fertilizer granulator for pelleting.

4.Next, the pelletized fertilizer is sent to the pelletizing equipment for rounding.

5.The particles after rounding reach the drying cylinder through the conveyor belt. The dried particles are then transported to the cooling drum through the conveyor belt for cooling.

6.The dust generated in the drying and cooling process enters the dedusting equipment through the induced air for dedusting. The cooled particles are then transported by the conveyor belt to the screening machine.

7.Then the sieved particles enter the quantitative packaging equipment through the conveyor belt for packaging, and become finished fertilizer.

Equipment selection of NPK fertilizer granulator

There are many types of fertilizer processing equipment in the above process, such as granulation link. Different types of NPK fertilizer granulators are suitable for different processing processes, including disc granulator, rotary drum granulator, roller extrusion granulator, etc. When selecting production equipment, fertilizer plants should consider their own plant planning, estimated annual output, type of raw materials, etc., which are related to how to select the most suitable equipment and ensure the maximum benefit.
Matters needing attention

Finally, fertilizer granulator equipment manufacturers remind everyone to consider the sales path of raw materials and fertilizers. Organic fertilizer raw materials that can be considered include crop straw, green manure, weeds and other plant materials, as well as manure and sludge. Attention should be paid to whether the raw material of livestock and poultry manure contains hormone residues, heavy metal overruns and other issues. The selection of bacteria should pay attention to the activity of bacteria and the number of useful live bacteria. Regarding marketing, we must examine the local fertilizer demand and transportation convenience.

On the production line of NPK fertilizers (nitrogen phosphorus potassium compound fertilizers), the commonly used types of fertilizer granulators mainly include drum granulators, disc granulators, and extrusion granulators. Among them, rotary drum granulators and extrusion granulators are common choices in NPK fertilizer production because they can handle the high mixing ratios and complex components required for NPK fertilizers, while ensuring the uniformity and stability of the particles. Below are the characteristics of these two types of granulators:

Drum granulator:

The rotary drum granulator achieves the granulation process through a rotating drum shaped container. The raw materials roll in the drum, and appropriate amount of water or binder is added through the spray system to gradually agglomerate the raw materials into particles. The rotary drum granulator is capable of processing highly viscous materials and is suitable for the production of NPK fertilizers, as it can effectively control the size and shape of particles while ensuring uniform distribution of fertilizer components.

Due to the complex composition of NPK fertilizers, the rotary drum granulator has become the preferred choice for NPK fertilizer production lines. It can process high concentration raw materials while controlling particle size and density by adjusting the drum speed and water spray system.

Squeezing granulator:

The extrusion granulator squeezes the raw material into strips through a pair of rollers (opposite rollers) that rotate in opposite directions, and then forms particles through cutting. This granulation method is suitable for dry or semi dry materials and can produce particles with high hardness and regular shape.

For NPK fertilizer production, the extrusion granulator can provide high-density, high-strength particles, which helps stabilize the fertilizer during transportation and storage. At the same time, the high production efficiency and particle uniformity of the extrusion granulator are also one of the reasons why it is popular in NPK fertilizer production lines.

The choice of granulator mainly depends on the production requirements, raw material characteristics, production scale, and cost considerations of NPK fertilizer

If high-density and high-strength particles need to be produced, and the raw materials are relatively dry, an extrusion granulator may be a better choice.

If the raw material contains high moisture or requires the addition of liquid binders during the granulation process to promote particle formation, a rotary drum granulator is more suitable.

Considering the complex composition of NPK fertilizers and the need to ensure uniform distribution of ingredients, the mixing capacity of the rotary drum granulator gives it an advantage in this regard.

In actual NPK fertilizer production lines, a combination of drum granulators and extrusion granulators may be used based on specific needs and raw material characteristics to achieve optimal production efficiency and product performance. In addition, other aspects of the production line, such as raw material pretreatment, drying, cooling, and packaging, also have a significant impact on the quality of the final product. Therefore, the comprehensive design and optimization of the entire production line are crucial.

The processing method of bio organic fertilizer is more complex than that of general compound fertilizer. The manufacturing of NPK fertilizer is mainly the mixing granulation of different fertilizers. The production of bio organic fertilizer involves composting and fermentation of feces.

Direct composting

The main technological process is to mix chicken manure with straw or peat, pile up about 1 meter high, compost at high temperature, periodically turn and ventilate fermentation, and use it as product after fermentation. The advantages of this mode are: the organic fertilizer manufacturing process is simple, less investment, low cost.

The main problem is that：

1. The accumulation time of products is too long, which is greatly affected by various external conditions, so the quality of products is difficult to guarantee.

2. The degree of continuous factory production is not high and the production cycle is long.

3. The product has low nutrient content and high moisture content, which can not meet the requirements of commercialization.
Tower fermentation

The main process is to mix chicken manure with sawdust and other auxiliary materials, and then connect to the biological bacteria agent. At the same time, the tower body is automatically ventilated, and the biological growth is used to accelerate the fermentation and deodorization of chicken manure. After a fermentation cycle, the product comes out of the tower body It’s basically a product. This model has the advantages of small footprint, low energy consumption, low pollution and high degree of factoryization.

But its current problems are:

1. Relying only on the biological heat generated by fermentation to remove moisture, the moisture content of the product cannot meet the requirements of commercialization.

2. The current process flow is not running smoothly, resulting in a large increase in labor costs, and the output fails to meet the design requirements.

3. The corrosion problem of equipment is serious, which restricts its further development.
Fermentation tank fermentation
This organic fertilizer manufacturing process is to mix chicken manure, grass charcoal, and sawdust into a cement tank, and use a compost turning machine to process the fermented material to fully ferment the material. After the fermentation is completed, the compost is crushed, sieved and packaged into products. The advantages of this model are: the production process is simple and convenient, the investment is small, and the production cost is low. It is very suitable for the bio-organic fertilizer manufacturing process, and is widely used in industrial production and processing.

Organic fertilizer composting equipment is simple and practical, and the fertilizer produced can be absorbed by crops quickly. In order to make better use of the compost turning machine in the organic fertilizer manufacturing process, it is very important to maintain the fertilizer equipment.

1. The bearing in organic fertilizer equipment bears all the load of the machine, so good lubrication has a great relationship with the bearing life

2. Lubricating oil directly affects the service life and operation rate of organic fertilizer equipment. Therefore, it is required that the lubricating oil injected must be clean and well sealed. The main oil injection place of the machine is the rotating shaft roller bearing, all gear movable bearings and sliding surfaces.

3. The newly installed wheel tyre is easy to loose, so it should be checked frequently.

4. Attention should be paid to the normal operation of each part of the compost turning machine.

5. Pay attention to check the wear degree of the easily worn parts of the turner machine and replace the worn parts at any time.

6. Dust and other sundries should be removed from the underframe plane of the movable device of the compost turning machine, so as to avoid serious accidents due to the failure of the movable bearing to move on the underframe when the machine encounters materials that cannot be broken.

7. When the rotating gear of turner machine is running, if there is impact sound, stop the machine immediately for inspection and eliminate it.

In the manufacturing of npk fertilizer and organic fertilizer, it is necessary to make a detailed description and solution to the wear and tear of machine parts and common faults in the instructions. On the other hand, routine maintenance is more important. Compliance routine maintenance can effectively reduce failures and prolong service life.

The rotary drum granulator is widely used in fertilizer manufacturing and other industrial fields, and its advantages are mainly reflected in the following aspects:

Easy to operate and maintain:

The structure of the rotary drum granulator is relatively simple, easy to operate, and user-friendly. Meanwhile, due to its simplified design, daily maintenance and troubleshooting are also relatively convenient, reducing maintenance costs and downtime.

Uniform granulation effect:

Low energy consumption:

Compared to other types of granulators, such as roller extrusion granulators, rotary drum granulators have lower energy consumption. This is mainly because its granulation process relies mainly on centrifugal force and the viscosity of the material itself, without the need for additional high pressure or high temperature.

High production efficiency:

The rotary drum granulator can operate continuously, process large amounts of materials, and achieve efficient batch production. This is particularly important for large-scale fertilizer production, as it can meet the demand for high yields.

Good cost-effectiveness:

Due to its simple operation, low maintenance costs, and low energy consumption, the rotary drum granulator has demonstrated high cost-effectiveness in long-term operation. For fertilizer manufacturers, this helps to reduce production costs and improve market competitiveness.

Environmentally friendly:

Low energy consumption and simple structure result in minimal environmental impact during the production process of the rotary drum granulator. This is a significant advantage for modern industries that pursue sustainable production and reduce their carbon footprint.

In summary, the rotary drum granulator occupies an important position in the fertilizer manufacturing industry and other industrial fields that require granular materials due to its advantages of easy operation, high production flexibility, low energy consumption, and good cost-effectiveness. By rational design and optimization of process parameters, the rotary drum granulator can efficiently produce high-quality granular products.

Sheep manure organic fertilizer dryer is also known as drum dryer. This dryer can dry fresh sheep manure with moisture content of 60% into granular dry products with moisture content less than 13%. It is a necessary equipment for organic fertilizer manufacturing process. In the process of organic fertilizer processing, the use of high temperature dryer to kill the bacteria in animal manure, and the use of water circulation and civil deodorization facilities in tail gas treatment can greatly reduce the air pollution and make the dry products easy to use, store and transport.

Sheep manure organic fertilizer dryer components:

It is mainly composed of rotary body, lifting plate, transmission device, support device and sealing ring. The length depends on the drying requirements. It is also commonly used in the manufacturing of NPK fertilizer and is one of the traditional drying equipment.Advantages of sheep manure organic fertilizer dryer

Sheep dung drum dryer has the function of improving the soil environment, improving the quality of crops, improving the quality of fruits and vegetables, and is beneficial to human health. It occupies an important position in agriculture.
The dried materials are sent to the cooler through the belt conveyor for cooling. In the cooling process, the natural air is sent to the cooler through the pipeline by the fan to cool the materials. The wind direction in the cooler is countercurrent. The tail gas pumped into the sedimentation chamber through the fan and pipeline is treated as the drying tail gas and discharged into the atmosphere.
The cooled materials enter the screening. After crushing, the large particle materials and the screened powder enter the return belt and are transported to the granulator for re granulation. The finished products enter the automatic packaging system for packaging.

 Agriculture has always been the top priority. Green ecological agriculture is the focus of social promotion. How can this goal be achieved?

The first is to reduce the use of chemical fertilizer, reducing the use of chemical fertilizer can effectively control the situation that the soil continues to be damaged. Then increase the use of organic fertilizer. The organic fertilizer made by compost turning machine is more safe and reliable than the self-made fertilizer. Moreover, organic fertilizer can supplement the soil organic matter, protect the soil from hardening, and when the soil nutrients are more, the quality of the crops planted will naturally improve, thus driving the development of the market.

Organic fertilizer manufacturing equipment has become more and more important for the current situation of agricultural production. Some countries and regions of agricultural production form, is facing a large-scale transformation, the traditional way of farming and fertilization, not in line with the sustainable development of agriculture, the promotion of organic fertilizer is particularly important, better promotion in the implementation of agricultural production, has become a challenge.

Organic fertilizer manufacturing process can quickly and effectively process livestock and poultry manure into organic fertilizer. The processing operation process is simple, the equipment technology is exquisite, the finished product is round and uniform, and the nutrients are balanced. It can meet the various nutrients required for crop growth and effectively relieve the soil. With the problems of agglomeration and nutrient imbalance, organic fertilizer equipment has become the main equipment in agricultural production.

The application of organic fertilizer equipment is becoming more and more popular. It is not only agricultural production machinery, but also a promoter of green ecological agriculture. As a manufacturer of organic fertilizer and NPK fertilizer manufacturing process, we hope that more agricultural producers can understand and understand, so that everyone can use high-quality organic fertilizer.

The rotary drum granulator has good adaptability to various materials due to its working principle and design characteristics, but the granulation effect and process control of different materials may vary. The following is an analysis of the adaptability of rotary drum granulators to different materials:

Organic materials:

High adaptability. Organic materials such as livestock manure, plant residues, etc. usually have a certain viscosity and humidity, which is conducive to forming particles through centrifugal force in a rotary drum granulator. Organic materials may require crushing and appropriate humidity adjustment before granulation.

Inorganic materials:

Good adaptability. Inorganic materials such as phosphate powder, potassium salt, sulfur, etc., although they may lack viscosity themselves, can improve granulation efficiency by adding appropriate binders or through physical and chemical interactions between materials. The granulation of inorganic materials usually requires finer humidity and temperature control.

Compound fertilizer:

High adaptability. Compound fertilizers are usually made by mixing organic and inorganic materials, combining the advantages of both, which can effectively improve the formability and stability of particles. Compound fertilizers may require finer mixing and pretreatment of raw materials before granulation.

Biodegradable materials:

Good adaptability. Biodegradable materials such as biomass waste and biodegradable plastics usually have good formability, and the granulation effect can be improved by adjusting the humidity of the raw materials and adding an appropriate amount of binder.

Special materials:

Adaptability needs to be evaluated. For some special materials, such as those containing high salt content, highly viscous materials, or materials containing hard particles, additional pretreatment steps may be required, such as cleaning, screening, or adding specific additives, to ensure the smooth progress of the granulation process.

additive:

Good adaptability. Additives such as binders and wetting agents can effectively improve the formability of materials and the stability of particles. Reasonable selection and use of additives can significantly improve granulation efficiency and product quality.

Overall, the rotary drum granulator has good adaptability to materials and can handle a variety of materials from dry to wet, from powder to granular** However, for specific materials, it may be necessary to improve their granulation performance through pre-treatment such as crushing, mixing, humidity adjustment, etc. In practical applications, selecting the appropriate granulator and adjusting granulation parameters (such as speed, feed rate, water spray system, etc.) are crucial for obtaining high-quality granular products.

In addition, the chemical properties of the material, such as pH value, salt content, nutritional composition, etc., can also affect the granulation process and the quality of the final product. Therefore, when using a rotary drum granulator to process materials, the characteristics of the materials should be fully considered, and the optimal granulation conditions should be determined through experiments or reference to granulation experience of similar materials.

Many people confuse organic fertilizer with organic carbon fertilizer and think that applying organic fertilizer is to supplement organic carbon. In fact, there are great differences between them in water solubility and organic component functional groups.

Difference between carbon based fertilizer and organic fertilizer

Organic fertilizer generally refers to carbon-containing organic materials made from animal manure, animal and plant residues, and leftovers processed from animal and plant products through an organic fertilizer production line. The main raw materials of organic fertilizer are excrement and straw, which are treated by compost turning machine and fermented and decomposed. Although organic fertilizer contains a lot of carbon, its water solubility is generally less than 10%, mostly around 3%, so the carbon availability is very low. It is difficult for crops to supplement carbon nutrition.

Organic carbon fertilizer refers specifically to fertilizers that are highly water-soluble and contain organic carbon compounds such as sugars, alcohols, and acids (including humic acid) that are easily absorbed by plants.

1. At present, organic carbon fertilizers are classified according to chemical types, including organic acids, such as acetic acid, propionic acid, amino acids, etc.; sugars, such as monosaccharides, disaccharides, and polysaccharides; alcohols, such as ethanol, propanol, and aldehydes.

2. According to the state of existence, it can be divided into solid state, liquid state and gas state.

3. According to the degree of structural complexity, it can be divided into simple carbon nutrients, such as monosaccharides, acetic acid, amino acids, etc.; complex carbon nutrients, such as humic acid, polysaccharides, hormones, peptides, vitamins, etc.

The organic carbon nutrition with complex structure is directly applied to crops, which can save more light energy and have more obvious fertilizer efficiency. Among them, humic acids and amino acid peptides with complex results are high-end products.

The production technology of carbon based fertilizer can be divided into fermentation treatment and chemical degradation treatment. Among them, humic acid and fulvic acid produced by efficient chemical degradation technology with lignite as raw material have high water solubility, do not flocculate in hard water, and have high physiological activity, which is a kind of high-end organic carbon fertilizer. We provide carbon based fertilizer production process, NPK fertilizer manufacturing process and organic fertilizer production line according to user needs.
