With the increase of crop yield per unit area and the increase of chemical fertilizer application, soil degradation is becoming more and more serious. Excessive application of chemical fertilizer, especially nitrogen fertilizer, is easy to cause soil nutrient imbalance, soil erosion, secondary salinization, soil acidification and other problems, resulting in the continuous decline of soil fertility.
Organic-inorganic compound fertilizer is a high-quality fertilizer for the production of green and pollution-free agricultural products. The yield of organic-inorganic compound fertilizer is about 10% higher than that of single chemical fertilizer.
Production technology of organic-inorganic compound fertilizer
In the production process of organic-inorganic compound fertilizer, when the fertilizer particles are extruded, there is no need to spray water before granulation, and there is no need to dry and cool after granulation. The granulation rate of flat die extrusion fertilizer granulator is more than 90%.
Because the base fertilizer is not heated, nutrients will not be lost.
Moisture control of flat die extrusion fertilizer granulator
Because there is no drying equipment in the production process of organic-inorganic compound fertilizer, controlling the moisture of appropriate raw materials and controlling the moisture of finished fertilizer within the standard range is the key to the production of flat mold granulator.
In the production of fertilizer granulator, the dosage of calcium, magnesium and phosphorus fertilizer should be strictly controlled. Before granulation, calcium superphosphate should be added to calcium magnesium phosphate fertilizer to neutralize the raw materials.
1. After mixed fermentation of strains and raw materials, composter is used in the fermentation process. Fermented compost can provide nutrients and improve soil properties, especially for sandy soil, clay and saline soil.
2. The rotten raw materials are crushed, screened and transported to the deep processing workshop by elevator.
3. The fertilizer is mixed by the raw material mixer and then enters the fertilizer granulator for granulation.
4. Next, the pellet fertilizer is sent to the granulation equipment for grinding.
5. The rounded particles reach the drying cylinder through the conveyor belt. The dried particles are then conveyed to the cooling drum through the conveyor belt for cooling.
6. The dust generated during drying and cooling enters the dust removal equipment for dust removal through induced draft. The cooled particles are then conveyed to the screening machine by the conveyor belt.
7. The screened particles enter the quantitative packaging equipment for packaging through the conveyor belt to become finished fertilizer.
Organic fertilizer production process
Equipment selection of NPK fertilizer granulator
There are many kinds of fertilizer processing equipment in the above process, such as granulation.
Different models of NPK fertilizer granulator are suitable for different processing processes, including disc granulator, drum granulator, drum extrusion granulator, etc. When selecting production equipment, fertilizer plants should consider their own plant planning, expected annual output, types of raw materials, etc., which are related to how to select the most appropriate equipment and ensure the maximum income.
Matters needing attention
Finally, the fertilizer granulator equipment manufacturer reminds you to consider the sales path of raw materials and fertilizers. Organic fertilizer raw materials that can be considered include crop straw, green fertilizer, weeds and other plant materials, as well as feces and sludge. Attention should be paid to whether the raw materials of livestock and poultry feces contain hormone residues and excessive heavy metals. The selection of bacteria should pay attention to the activity of bacteria and the number of useful live bacteria. In terms of marketing, we must investigate the local fertilizer demand and convenient transportation.
With the improvement of living standards, people’s demand for machinery and equipment is increasing, and their dependence on machinery is also gradually increasing, which brings pressure to the development of organic fertilizer production equipment.
In the process of fertilizer production, in order to ensure the safety and operation of the production line, operators need to strictly require themselves to operate the equipment correctly. So how should we operate correctly in the operation of organic fertilizer production line? SX company, a large fertilizer equipment manufacturer, provides you with suggestions.
Requirements for safe operation of organic fertilizer production line
2. As workers operating organic fertilizer equipment, they should first standardize their working attitude. Because correct operation is closely related to everyone’s safety, we must not be careless in the operation process, otherwise the materials may be damaged and personal safety may be endangered.
3. Organic fertilizer equipment shall be placed in a reasonable position, and attention shall be paid to ventilation and ground wire. When it is found that it cannot be operated, the workshop production shall be stopped immediately, and the problems shall be found out and handled.
4. Clean the machine in time after using the equipment, especially NPK fertilizer granulator. Regular maintenance of equipment appearance and smooth parts can ensure production and quality, and then bring economic benefits to the company.
5. The complete set of organic fertilizer production equipment shall be installed on the horizontal concrete foundation, especially the large equipment such as drum granulator, drum dryer and cooler shall be fixed with anchor bolts.
Pay attention to the verticality between the main body and the horizontal plane during installation. Configure the power cord and control switch according to the power of the equipment. No load commissioning shall be carried out after passing the inspection, and production can be carried out only after the commissioning is normal.

In the process of organic fertilizer production, how to granulate the fermented raw materials is the key factor to determine whether the commercial fertilizer can enter the market. The following granulation methods are generally used.
Fertilizer production line
(1) Agglomerate granulation. Under the action of rotation, vibration and stirring, the wet powder in motion is agglomerated. Or the fluidized bed is used to coagulate dry powder and particles into suitable particles by supplying spray solution (adhesive).
(2) Extrusion granulation. It is a method of making dry powder or wet powder containing adhesive into cylindrical, spherical or sheet by mechanical processing such as extrusion, roll extrusion or pressing.
(3) Crushing and granulation. It is to crush block materials into particles of appropriate size.
(4) Melt granulation. It is a method of granulation by cooling and hardening molten liquid.
(5) spray granulation. It is a method of directly granulating solid after concentration in liquid.
(6) Liquid phase crystallization granulation. It is a method that materials crystallize in liquid phase and agglomerate into spherical particles through liquid bridging agent and stirring.
This technology is widely used in pharmaceutical industry. Because the particle shape is spherical, it is also called spherical crystallization granulation method, which is abbreviated as spherulite granulation method.
Spherulite particles are pure material particles with good fluidity, filling and compression formability. In recent years, the technology has been successfully developed. That is, polymer copolymer precipitation is added in the spherulite crystallization process to prepare sustained-release, rapid release, enteric coated, gastric coated pellets, floating hollow pellets, biodegradable microcapsules, etc. Preparation of sustained release pellets.
The manufacturing process of organic fertilizer is mainly to screen and magnetic separate the organic waste with a water content of about 30% ~ 35% after fermentation and decay to make a round grain organic fertilizer, add functional bacteria to produce biological organic fertilizer, and add nitrogen, phosphorus and potassium (the total nutrient content is less than 15%) to produce organic and inorganic fertilizers.
After the fermented organic waste is screened by magnetic separation, the raw materials containing binder and other compatible components are measured according to the proportion requirements, and then lifted by bucket elevator to multi-dimensional high-efficiency mixer for rapid mixing.
The mixed material slides out of the mixing bin and is continuously and evenly sent to the extrusion granulator by the disc feeder to make cylindrical particles; The cylindrical particles are polished into spherical particles by the circular particle polishing and setting machine and formed by the belt.
The machine is sent to the drying, cooling and screening machine (three in one model). The particles are dried at low temperature and large air volume (≤ 65 ℃) in the front section of the drying cooling screening machine, and then enter the cooling section for air cooling. After sufficient cooling, the materials enter the screen installed at the end of the cylinder.
The screened finished product particles are transported to the finished product silo by the elevator and measured and packaged by the packaging system; The screened large particles are crushed and returned to the mixed granulation system; The screened small particles (basically without powder) can be made into small packages and sold directly.

Advantages of toothed stirring granulator in organic fertilizer granulation
Wet organic stirring fertilizer granulator is used to granulate various organic substances after fermentation, breaking through the conventional organic granulation process. The particles can be directly mixed and processed without drying or crushing the raw materials before granulation, which can save a lot of energy.
Wet organic fertilizer stirring granulator is widely used for granulation of organic fertilizer. Because of its large granulation rate, stable operation, strong and durable equipment and long service life, it is selected as an ideal product by the majority of users. The internal rotating tooth granulator developed by our unit has Φ 600、 Φ 800、 Φ 1000、 Φ 1200 four specifications. Other specifications of stirring granulator can also be produced according to user requirements.
The shell of granulator adopts thickened seamless steel pipe, which is firm and durable and not easy to deform. Coupled with the solid base design, it runs more smoothly.
Using the mechanical stirring force of high-speed rotation and the resulting aerodynamic force, the fine powder materials can be continuously mixed, granulated, spheroidized and densified in the machine to achieve the purpose of granulation. The particle shape is spherical, the sphericity is ≥ 0.7, the particle size is generally between 0.3-3mm, and the granulation rate is ≥ 90%. The particle size can be appropriately adjusted by the mixing amount of material moisture and spindle speed. Generally, the lower the mixing amount, the higher the speed, the smaller the particles, and vice versa.
Scope of application: This machine is especially suitable for granulation of light and fine powder materials. The finer the basic particle of fine powder material, the higher the sphericity of the particle, and the better the quality of the ball. Generally, the particle size of materials before granulation shall be less than 50 mesh. Typical application materials: chicken manure, pig manure, cow manure, carbon black, clay, kaolin, etc.
Wet organic fertilizer stirring granulator is suitable for organic wastes such as peat, sludge, chicken manure, livestock manure, lignite, sugar mill filter sludge, papermaking sludge, wine, straw, soybean residue, peat and so on. Direct granulation completely solves the key technical problems that cannot be solved by traditional granulation processes such as disk (drum) fermentation, and granulation with bio organic fertilizer as raw material.
Plant ash is the residue of firewood after combustion. It belongs to alkalinity. The main component is potassium carbonate (K2CO3) which can be used as fertilizer. Before the widespread use of chemical fertilizers, agricultural plant ash refers to the ash produced after burning and eating by mountain grass, straw and branches (excluding the ash produced by coal).
Plant ash shall not be mixed with other fertilizers during storage. Some farmers are used to putting ash in puddles and mixing it with organic fertilizer and straw, which is very wrong. Because the ash is alkaline, it will cause the volatilization of nitrogen in organic fertilizer and reduce fertilizer efficiency. Such treatment will not only waste fertilizer, but also pollute the environment.
Ashes must be applied separately. Plant ash cannot be mixed with organic farm manure and ammonium nitrogen fertilizer to avoid nitrogen volatilization loss, nor can it be mixed with phosphorus fertilizer to avoid phosphorus fixation and reduce the use efficiency of phosphorus fertilizer.
Therefore, when planning the fertilizer manufacturing process and using plant ash as organic raw material, the fertilizer plant should pay attention to the proportion of raw materials.
1. Soil application: since the ash is alkaline, cohesive soil, acidic or neutral soil should be used. Soil application can be used as base fertilizer, seed fertilizer and topdressing, as well as seedling raising and seedling covering (seed covering fertilizer).
When used as base fertilizer and seed fertilizer, the amount of fertilizer should not be too large, and should be isolated from seeds to prevent seed burning. Generally, 50-100kg per mu is appropriate.
It is suitable for centralized soil application, strip application or hole application, with a depth of 8-10cm, and covered with soil after construction. Mix the wet soil 2-3 times or spray a little water before application.
2. Topdressing outside the root: more than 90% of the potassium contained in plant ash is soluble in water, which is a quick acting potassium fertilizer. According to this characteristic, plant ash can be used as extraroot topdressing, that is, 1% concentration of plant ash extract can be used for foliar spraying.
3. Priority crops: plant ash is suitable for various crops, especially potassium free or potassium free and chlorine free crops, such as potato, sweet potato, tobacco, grape, sunflower, sugar beet, etc.
Plant ash can be used for potato, not only for soil application, but also for potato wounds. In this way, it can be used as seed fertilizer to prevent wound infection and decay.
Typical application materials: chicken manure, pig manure, cow manure, charcoal, clay, kaolin, etc. This machine is most suitable for direct granulation of organic fertilizer after fermentation, eliminating the drying process and greatly reducing the manufacturing cost.
The new organic fertilizer granulator uses the mechanical stirring force of high-speed rotation and the generated aerodynamic force to continuously mix, granulate, spheroidize and densify the fine powder materials in the machine, so as to achieve the purpose of granulation. The particle shape is spherical, the sphericity is ≥ 0.7, the particle size is generally between 0.3-3mm, and the granulation rate is ≥ 90%.
Organic fertilizer raw materials (animal manure, domestic waste, dead leaves, biogas residue, waste bacteria, etc.) are fermented into a semi wet material crusher for crushing, and then nitrogen, phosphorus, potassium and other elements (pure nitrogen, phosphorus pentoxide, potassium chloride, ammonium chloride, etc.) are added to make the mineral elements meet the specified standards, then stirred with a mixer, and then enter the granules of the new organic fertilizer granulation mechanism.
After drying, the screened qualified products are packaged by the screening machine, and the unqualified products are returned to the granulator for granulation.

How to improve the product output and output, the key lies in the organic fertilizer granulator.
1、 According to the moisture, fineness and cohesiveness of raw materials.
Powder raw materials form spherical particles through the attachment of water. Therefore, controlling water and making water uniform have become the key factors to improve yield. The lower the moisture content, the lower the granulation rate, the higher the moisture content, the more large particles, the uneven moisture, the smaller the particle size, and the lower the yield.
2. Material fineness
It is needless to say that the material fiber has natural coarse granulation effect, rough and brittle appearance and poor formability. The higher the fineness, the better the formability and the smoother the particles.
3. Is the material sticky
In particular, organic fertilizer granulation, general raw animal manure (chicken manure, pig manure, cow manure, sheep manure, pigeon manure, etc.), straw (corn straw, straw, leaves, etc.), fungus residue, sugar residue, drug residue, monosodium glutamate residue, etc. The viscosity of general materials is poor, so some viscous fillers such as bentonite need to be added.
2、 Fertilizer granulator is selected for organic fertilizer production line.
If columnar is produced, ring mold granulator and columnar extruder are selected.
For irregular and flat ball type, select the appropriate drum extrusion granulator (depending on the die).
All kinds of granulation equipment have their own advantages and disadvantages. Different equipment shall be selected according to raw materials, investment cost (drying or not) and the needs of farmers.
Let’s take a look at the process conditions and process settings of organic fertilizer production.

After screening the fermented organic waste, the binder raw materials and other components to be compatible are measured and proportioned in proportion, and quickly mixed by the bucket elevator into the fertilizer mixer for rapid mixing.
The material slides out of the mixing bin and is evenly and continuously fed into the flat die extrusion fertilizer granulator by the disc feeder to form columnar particles; Cylindrical particles (equal in diameter and length) are polished by a circular particle polishing machine. The spherical particles are sent to the drying, cooling and screening machine by belt conveyor.
The particles are dried at low temperature and large air volume in front of the drying cooling screening machine, and then enter the cooling section for air blowing. The cold and completely cooled materials enter the screen installed at the end of the cylinder, screen out the powder and large particles, and return to the mixed granulation system; The finished product particles are transported to the finished product silo by the elevator, measured, packaged and warehoused.

Organic fertilizer refers to all kinds of animal manure (including animal manure and animal processing waste) and plant residues (cake fertilizer, crop straw, leaves, dead branches, peat, etc.) by physical, chemical, biological or organic methods.
The three treatment technologies remove pathogens, viruses, insect eggs, grass seeds, harmful gases and liquids carried by animal debris through standard decomposition process, and fertilizer types that meet relevant national standards. After processing through the organic fertilizer production line, harmful substances are removed and rich in a large number of beneficial substances.
The organic fertilizer granulation production line can process fertilizer into particles or powder. If it is powdery, just crush it. However, if it is granular, the powdered fertilizer needs to be granulated through the fertilizer granulator to obtain granular fertilizer. Fertilizer granulation is an important process in the manufacturing process of organic fertilizer.
Granulation quality affects fertilizer quality. The final finished fertilizer.
In the actual agricultural production, most farmers still choose to use granular organic fertilizer. So why granulate fertilizer in the manufacturing process of organic fertilizer? What are the advantages of powder compared with organic fertilizer? Find machines for organic compound fertilizer production, welcome to https://organicfertilizermachines.com/
1. Fertilizers with very low water solubility are usually crushed into small particles to ensure that they are quickly and effectively dissolved in the soil and absorbed by plants.
2. The control of fertilizer particle size is very important for the storage and transportation of fertilizer. Good granulation makes organic fertilizer not easy to agglomerate and better transportation performance.
3. Some inorganic components can be added in the manufacturing process of organic fertilizer to improve the fertilizer efficiency of organic fertilizer. If inorganic components are added to powdered fertilizer, it is easy to absorb moisture and caking.
4. Fertilizer granulation improves agricultural technology. Fertilizer particles play the role of slow-release fertilizer effect. Fertilization is convenient and not easy to be blown away by the wind.
The new organic fertilizer granulator, disc granulator, flat mold granulator and ring mold granulator produced by our company are widely used in the organic fertilizer granulation production line to meet the different production needs of customers and achieve good economic benefits.

Conditions for constructing small organic fertilizer production line
What conditions do we need to build a small organic fertilizer production line? Small organic fertilizer production line can be a powder organic fertilizer production line, or can be a granular organic fertilizer production line.
The production lines of organic fertilizer with an annual output of less than 20000 tons are small organic fertilizer production lines. According to the planning of most customers, the small organic fertilizer production line has 5000 tons, 10000 tons, 15000 tons and 20000 tons.
Because the production line of powdery organic fertilizer is the component of the production line of granular organic fertilizer, we will use the granular organic fertilizer production line to elaborate the technology of small organic fertilizer production line today. The technology of fertilizer production line will be clear.
Process flow of granular organic fertilizer production line:
So, what conditions do we need to build a small organic fertilizer production line?
(1) The construction of small-scale organic fertilizer production line meets the requirements of environmental protection policy. Environmental protection is not only the desire of the people, but also the policy demand for environmental protection for the development of agriculture and animal husbandry;
(2) Raw material source, radius of raw material source, determine your plant location, site investment, transportation investment, etc;
(3) The types of raw materials, the specific equipment types used in each stage of the process, and the investment price of the equipment are affected;
(4) The production scale, the production capacity of small organic fertilizer production line from 3000 tons to 20000 tons determines the equipment capacity requirements, thus affecting the price;
(5) The recycling of resources mainly depends on a variety of agricultural pollution waste recycling methods, such as fuel and electricity raw materials, and biogas residue is used as organic fertilizer raw material;
(6) Other small organic fertilizer production line technology, can be used as feed.
(7) Site: the size of production site and investment of site scale shall be determined according to the planned production scale.
Organic fertilizer is a kind of organic fertilizer made from poultry manure, combined with fermentation bacteria, straw and other auxiliary materials, using traditional fermentation methods or organic fertilizer production equipment.
For commercial organic fertilizers on the market, two more popular forms of finished organic fertilizers are powdered and granular. What is the processing technology of powdery organic fertilizer and granular organic fertilizer? Which is better?
In the process of making a series of special fertilizers, inorganic nutrients and minerals should be added according to different soil conditions and different crops. These minerals are concentrated in organic matter and trace elements, so that the fertilizer contains various nutrients needed for plant growth, such as nitrogen, Phosphorus, potassium, sodium, manganese, zinc, copper, etc.
According to the formula, nitrogen, phosphorus, potassium and fermentation material are mixed by computer and transferred to granulator for granulation. We mix organic and inorganic materials according to different series of products, and mix them well in blender. Assume that the proportion of organic materials is 12%, about 12 tons.
The production process should not be exposed to high temperature and other characteristics due to the poor formation conditions of bio fertilizer mainly composed of organic matter and cellulose and the viable bacterial population with the function of making fertilizer.
Disc granulation and drum granulation are not suitable for building materials, because these two technologies require fine grinding of raw materials, high moisture content of granulation, and generally the moisture content is about 30%, so the load is relatively large. There are different types of fertilizer granulators for your fertilizer granulation process.
For drying, the loss of effective bacteria is great, and the pelleting rate is low (about 60% – 70%), the dust is heavy, and the operating environment in the production process is poor.
Therefore, through the extrusion environment, the requirements of raw material crushing are low, the molding rate is high (more than 95%), the water content of formed particles is low, the drying load is low, the environment is dry, and the production of organic biological functions should be better. Can reduce the loss of effective bacteria, less dust and good working environment.
70 tons of organic fertilizer raw materials, using organic fertilizer special granulator. After granulation, the material is sent to the dryer by belt conveyor for drying. The particle size is 3.0-4.0 mm, and the granulation rate is more than 70%.
The recommended pelletizer is a new type of pelletizer for organic fertilizer.
(4) Drying (fertilizer dryer)
In the production process of biological fertilizer, not only does the moisture content of granules generally exceed the index after molding and need low-temperature drying, but also the moisture content of organic matter after fermentation is about 30% – 40%, and the granule after granulation is generally between 15% – 20%, which needs drying treatment, because the moisture content of fertilizer quality index is less than 14%.
The drying stage is an essential and important process in the production of biological fertilizer, which directly affects the yield, quality and energy consumption. It is very important to choose the type and specification of dryer and control the process conditions.
In order to avoid the death of effective living bacteria due to the high temperature in the drying process, the drying temperature of materials should not be higher than 60 ℃ (usually about 50 ℃). Therefore, the temperature of hot air in contact with materials should be different.
For the moisture content of different materials, generally not more than 130 ℃, it is better to control the hot air temperature by stages, which can not only improve the thermal efficiency, but also effectively avoid the death of living bacteria.
According to these characteristics, the belt dryer is suitable, because it is suitable for low temperature and low humidity drying, and it can control the temperature of hot air in sections to ensure that the material temperature is not higher than the drying temperature, and maintain the highest temperature in the whole process.
