The process of processing livestock manure into organic fertilizer:
The first step: fermentation
Collect livestock manure, mix it with hay and decaying silage, etc. to make compost, and let it ferment. In the fermentation process, the pile turning machine is used to fully ferment the livestock manure, which can only be achieved by turning the pile in time and evenly. Now some places are very dry and some places are very wet, which will affect the quality of fermentation.

The second step: the ingredients are crushed and mixed
Use the batching bin to pulverize, proportion and mix the composted materials, N, P, K and other inorganic fertilizers, and other additives and other raw materials in a certain proportion through a material crusher machineand a horizontal mixer machine.
The granular materials output from the granulation forming system have certain differences in particle size and need to be sieved and classified. The selected rotary screening machine requires low vibration, low noise, convenient screen change, and is equipped with a screen surface cleaning device. It is recommended to be equipped with an automatic material return system to screen unqualified large and small particles, convey them through a belt elevator, and send them to the pelletizer to continue pelletizing after being crushed again, which helps to improve the continuous operation capacity of the production line.

Step 5: Drying
Use an organic fertilizer drying machine to further remove water from the sieved particles to meet the standard requirement of organic fertilizer moisture content.
Step 6: Cool down
Cooling the granular materials with a cooler helps the storage and quality of the granules.
Non-drying granular fertilizers include urea, ammonium phosphate, compound fertilizer, potash fertilizer granules, etc., fertilizer granulation is one of the development trends of fertilizers. Compared with powdered fertilizers, granular fertilizers have good physical properties, no dust, long-term storage and no agglomeration, good fluidity, easy to spread fertilizer, and can realize aircraft sowing. At the same time, it can also play a slow-release effect and improve fertilizer performance. Utilization rate. There are three common methods for processing this kind of non-drying granular fertilizers: disc granulation, recrystallization and extrusion granulation. After long-term practical experience, we recommend using a pair-roll extrusion granulator to process non-drying granular fertilizers. , This kind of processing using a pair of roll extrusion granulator is more practical.
Double Roller Granulator in Manufacturing
Dry powder-free processed granular fertilizers are mainly used for processing compound fertilizers and compound fertilizers. As the raw material of compound fertilizer, powdery is suitable, but as fertilizer for direct use, granular fertilizer is better than powdery products. The common processing methods of dry granular fertilizer include disc granulation, recrystallization and extrusion granulation. The three granulation methods have their own characteristics.
Comparison of three methods of non-drying granular fertilizer processing
Disc granulation. Disc granulation requires adding a binder to the powder, and at the same time it is obtained by drying and sieving. This method requires the addition of ineffective ingredients such as binder (usually clay) and water to reduce the nutrient content of the product.
Recrystallization method. The powder is dissolved in water, cooled, crystallized and separated into crystals and then crushed and sieved. The method has a complicated process, high cost, high consumption, and low market competitiveness.

Extrusion granulation method. A tablet press or an extrusion granulator is used to forcibly squeeze the powdered potassium fertilizer into tablets, which are then made into granules through processes such as slicing, granulating, and sieving. There are two types of extrusion granulation: roller type and wheel roller type. The roller type extrusion is firstly pressed into large pieces and then crushed into particles. In this way, the device has large capacity, high particle strength and low energy consumption. The wheel rolling type is to directly squeeze the material into a cylindrical strip in the laminating film, and then cut it into columnar particles. Most of the extrusion granulation methods currently used in China are wheel pulverization, and the production scale is small. A single double roller granulator machine can only reach 3~5t/h, and the granulation strength is limited, the mold is damaged, and the production is cylindrical granules. , Poor flow performance and other characteristics.

The double-roll extrusion granulator has obvious advantages in processing non-drying granular fertilizers
The roller squeezing granulator adopts rolling molding and crushing into granules. Extrusion granulation production has a wide range of raw material routes. At present, there are more than 20 kinds of materials that have been successfully used for extrusion granulation: ammonium nitrate, urea, ammonium chloride, calcium nitrate, potassium chloride, potassium sulfate, etc. In addition, the extrusion granulation process can flexibly realize the replacement of product formulas in a very short time, and a set of equipment can produce products with more than 30 formulas.
The design of the roller extrusion granulator is very reasonable, very practical, and low energy consumption. It can be continuously produced without drying at room temperature and once rolled and formed. The ball and socket on the roller can be manufactured according to the size and shape of the customer’s needs. At present, we There are spherical, pillow-shaped, semi-circular grain, rod, pill shape, walnut shape, oblate shape, and square shape. It is now used as a new energy-saving product in the compound fertilizer and organic fertilizer industry.
Organic fertilizer equipment manufacturers not only provide equipment products, but also provide technical services. The intervention of equipment manufacturers is inseparable from the preparation of the pig manure organic fertilizer processing production line from the early stage to the later stage of production, from ground infrastructure guidance, process design, equipment customization, equipment installation, customer technical personnel training, after-sales technical guidance, etc. , All need the service and support of the equipment manufacturer. A company with a good reputation, good service and good reputation is the consideration for choosing a pig manure organic fertilizer equipment manufacturer.
The roller extrusion granulator belongs to the extrusion slip model. Its working principle is: the belt and pulley are driven by the motor, transmitted to the driving shaft through the reducer, and synchronized with the driven shaft through the split gear, and work in opposite directions. The material is added from the hopper, formed by the pair of rollers, demoulded and pelletized, and then sent to the crushing screen studio through a pair of chains, where the finished product particles (balls) are screened and separated, and then the returned material is mixed with the new material. Then granulate. With the continuous rotation of the motor and the continuous entry of materials, mass production can be realized.

What equipment is needed to process organic fertilizer? Next, FPC will introduce the organic fertilizer equipment that needs to be used in conjunction with the production process of organic fertilizer.
moving type caomposting machine
Fermentation of raw materials
The first step in the production of organic fertilizer is the fermentation of raw materials. There are three types of equipment used for raw material fermentation: manure fermentation tanks, self-propelled compost turners, and trough type compost turners. The purpose of using equipment is to save labor, speed up the fermentation of raw materials, make the fermentation of raw materials more uniform and thorough, and have reached the organic fertilizer content standard. The success or failure of organic fertilizer fermentation determines the quality of organic fertilizer, so theselection of fermentation equipment is very critical.
Raw material crushing
In order to make the fermented organic fertilizer look even and fine, it is necessary to use a semi-wet material crusher to crush the raw materials. After crushing, high-quality powdered organic fertilizer can be obtained. The raw materials that are not thoroughly crushed need to be screened out by an organic fertilizer drum screening machine. Carry out secondary pulverization. If granular organic fertilizer is produced, the sieving step should be continued after the cooling process.
organic fertilizer granulation machinery
Granulation
In order to be more convenient for transportation and storage, the powdered organic fertilizer needs to be granulated. The granulated organic fertilizer has high strength and density, which is more convenient for transportation and more convenient for later use. Generally, a new type of organic fertilizer stirring tooth granulator is used for granulation.
Drying and cooling
The raw material during granulation still contains about 30% moisture, so the moisture in the granules should be removed in time after granulation to further improve the strength and prevent moldy or crushed during bagging and transportation. The granules need to enter immediately after being dried. The cooling system is convenient for further evaporation of water, and on the other hand, it is cooled and shaped. At this time, a rotary dryer and a cooler are needed.
rotary fertilizer screening equipment
Particle screening
In the process of processing, there will be a small amount of oversized and oversized particles, which are screened out by the organic fertilizer drum screener. The oversized particles are returned to the granulator, and the oversized particles are returned to the pulverizer. Realize fully automated production.

Each customer has different conditions, different raw materials and different processes, so the required equipment is also slightly different. You can call to inform the details, and we will develop a suitable organic fertilizer production plan according to your situation for your reference.
Organic fertilizer manufacturing equipment is needed to make animal manure as organic fertilizer. The performance characteristics of the equipment determine the different uses of the equipment and the pros and cons of the equipment. As we all know, animal manure is a good organic fertilizer, which can make the soil fertile, overcome soil compaction, provide plant nutrition, and improve crop quality. However, how to deal with animal manure must first be fermented and decomposed. Fermentation can promote the decomposition of organic fertilizer and increase fertilizer. The effective ingredients of the fertilizer are fermented at high temperature, insect eggs and weed seeds are used to kill germs and make environmentally friendly organic fertilizer. The organic fertilizer turning machine is a special equipment for fermentation and decomposing. Let’s take you to understand the equipment performance characteristics and process principles of using animal manure as organic fertilizer.
Organic-Fertilizer-Granular-Production-Line[1]Performance characteristics of animal manure as organic fertilizer equipment
Animal manure organic fertilizer has a kind of organism and enzyme, which can enhance the biological properties and enzyme activity of the soil, increase the nutrient content of the soil, and improve the pH of the soil, so that the soil can be suitable for the growth of various agricultural practices.
The organic fertilizer produced by the pig manure organic fertilizer production line is highly nutritious. If it is put in evenly, no additional fertilizer is needed for at least 100 days. This effect cannot be replaced by any fertilizer.
The animal manure organic fertilizer production line can add anti-disease and insect pests drugs during production to reduce disease and insect pests and rodents.
The organic fertilizer produced by the animal manure organic fertilizer production line is rich in nutrients, and in addition to the three major nutrients of nitrogen, phosphorus and potassium, there are also rich calcium, magnesium and silicon, etc., which change the composition of the soil and are beneficial to crop growth.
①The raw material is fermented, fermented and crushed. After crushing, the sieving machine sieving, the sieving machine sieving out qualified powdery organic fertilizer, then the automatic packaging scale packaging, sealing, and each equipment is transported by a belt conveyor.

The organic fertilizer production line of FPC livestock and poultry manure organic fertilizer equipment has reasonable design, fine production, compact appearance, reasonable price, and good after-sales service. It can produce powdered organic fertilizer or hardcover organic fertilizer (that is, granular). The company can specify the equipment required according to the specific situation of the customer, according to your situation to plan the site area, equipment placement, and help you install and debug. Welcome to negotiate and purchase.
Mixing of raw materials: the main material is livestock manure, the ingredients (straw, waste tobacco, planting and processing waste, etc.) are crushed, organic and biological bacterial fertilizers are added, and some phosphate rock powder, potassium ore powder, and phosphate rock can be appropriately added Try to purchase medium-grade phosphate rock (total phosphorus content> 18%). The amount of phosphate rock powder added to the organic fertilizer raw materials needs to consider the pH of the raw materials. More phosphate rock powder can be added to the weakly acidic raw materials, and natural potassium magnesium sulfate fertilizers should be less added to the neutral and slightly alkaline raw materials to adjust the nutrients and carbon of the materials. Nitrogen ratio, carbon to phosphorus ratio, pH value, etc. After treatment, the moisture content of the raw materials is controlled at 60%-65%, and the C/N ratio is 20-30. The production of bio-organic fertilizer needs to add beneficial bacteria and functional bacteria, and it needs to be added when the temperature of the material is less than 40 degrees after the high temperature period of fermentation. The paddle-type compost turning machine can control the materials in the tank in sections, which is convenient for operation, and makes full use of the equipment’s ingredient mixing function, fermentation mixing function, and mixing and drying function to simplify the production process. This process is designed as an integrated workshop for ingredient mixing, fermentation, aging (decomposition), and drying to reduce multiple handling of materials.

Note: In the composition of raw materials before composting, the carbon-nitrogen ratio and moisture of the raw materials are mainly considered, followed by particle size and pH: the reasonable range of carbon-nitrogen ratio: 20:1-40:1, the best range: 25:1- 30:1; reasonable range of moisture content: 40%-65%, optimal range: 50%-60%; reasonable range of particle size: 0.32cm-1.27cm, depending on materials, piles and weather; reasonable pH Range: 5.5-9.0, best range: 6.5-8.0.
Fermentation: Fermentation of organic fertilizer raw materials adopts aerobic fermentation process, adopts trough type fermentation turning machine, and blades (rotating tooth type, positive and reverse) to cut and throw materials, which can make organic materials move backward during turning. Each turn moves backward about 2.2 meters. The turning and throwing machine has a mixing function and can be used as a mixer. During the batching, the layered materials can be mixed evenly and then enter the fermentation area (or fermentation period), which can greatly save the investment in raw material pre-mixing equipment and material loading and unloading transportation and pre-mixing work Mix the broiler manure, cassava residue and 0.15% organic material decomposing agent as evenly as possible, stack 60-80 cm high stacks, turn the stacks once every 2-3 days with a turning machine, and control the temperature during fermentation. Below 70°C, the odorless effect is generally achieved in about 20 days, that is, the fermentation is completely decomposed.
Organic manure composting site
Note: During the composting process, the temperature change is mainly controlled. The complete composting process consists of four stages: low temperature, medium temperature, high temperature and cooling. The compost temperature is generally maintained at 50-60°C, and can reach 70-80°C at the highest point. The process of gradually increasing the temperature of the compost is a process of harmless composting (the temperature of the compost is maintained between 45℃-65℃ for 10 days, and pathogenic bacteria, insect eggs and grass seeds can be killed). When the compost temperature rises above 60℃, keep it for 48 hours to start turning the pile, but when the compost temperature rises above 70℃, turn the pile immediately. Make sure to turn the pile evenly and thoroughly. Try to turn the bottom material to the middle and upper part to fully decompose. The frequency of turning depends on the maturity of the organic fertilizer. The pH is controlled in the fertilizer. In the initial stage of composting, organic acid is generated due to the decomposition of organic matter. decline. At this time, if the acidity is too high (pH<5.3), lime or plant ash can be added at 2%-3% of the weight of the raw materials to neutralize the acidity, destroy the wax on the surface of the organic materials and accelerate the fermentation; in the later stage of composting, due to the accumulation of ammonia, the pH It will gradually increase. When the pH is greater than 8.5, fresh green manure, grass, etc. can be added to decompose and regenerate organic acids and lower the pH.

Air-drying and sieving: transport the fermented raw materials to the outdoor drying yard, and after natural drying, ensure that the water content is below 20%, that is, the air-drying is completed, and the air-dried raw materials are crushed through a crusher and then passed through the screen. Sieve to remove impurities.
Note: It is recommended to properly carry out the secondary fermentation in the post-processing of the compost (before air-drying), especially for the raw materials with a large proportion of livestock and poultry manure in the primary fermentation, so as to prevent the finished fertilizer from being applied to the soil and rapid propagation in the secondary fermentation The microorganisms compete for oxygen with the roots of vegetables, resulting in the phenomenon of burning roots and seedlings.
Pan Compost Pellet Machine
Inspection and packaging: After the crushed and sieved organic raw materials are inspected (sent for external inspection), they are directly quantitatively packaged, which is the powdery finished organic fertilizer. Granulation by the organic fertilizer granulator is the granular finished organic fertilizer.
Note: Before sending for external inspection, judge whether the finished fertilizer is completely decomposed by the color and smell. The completely decomposed organic finished fertilizer can be applied for external inspection. The incompletely decomposed finished fertilizer needs post-processing (or secondary fermentation). The finished fertilizer that has passed the external inspection can be directly bagged or pelletized and then bagged. The finished fertilizer that does not meet the required nutrient content in the external inspection result needs to be returned to the composting workshop, and high-nutrient content raw materials are added to compost and ferment again.

The production of compound fertilizer by extrusion granulation process has the following advantages and disadvantages
Extrusion granulation does not require heating and humidification of the materials, which saves investment and energy, and can also be adapted to the granulation of ingredients containing heat-sensitive materials, such as ammonium bicarbonate and certain organic fertilizers.
No waste water or waste gas is discharged outside during the production process, and it will not pollute the environment.
There are no special requirements on the properties and particle size distribution of the raw materials, so the source of raw materials is relatively wide.
The production is more flexible, and the product plan can be changed at any time, which is conducive to the production of special fertilizers in small batches.
The product has uniform particle size distribution, no segregation or agglomeration.
The shape of extrusion granulation products is not as round as the particles produced by traditional methods such as drum granulation and slurry granulation; if chemical reactions occur between the ingredients in the product particles, the particles may collapse.

large scale wheel type compost turning machine
It should be noted that there are several advantages after using organic fertilizer production line equipment to make organic fertilizer into the size and shape of chemical fertilizer, that is, it can make the land easier to absorb, make the organic fertilizer evenly distributed, and facilitate the transportation and storage of the fertilizer. . FPC organic fertilizer production line equipment is well-known in the organic fertilizer processing industry for its reliable equipment performance, stable and high yield, and has been exported to more than 30 countries and regions.
With the development of environmental protection and organic agriculture, the use of organic wastes to produce organic fertilizers through biological fermentation has been rapidly developed, making the treatment of organic wastes harmless and resourceful. However, most of the organic fertilizer obtained by biological fermentation is coarse powder or irregular small lumps, which is very inconvenient to use, and is particularly unfavorable for large-area machine sowing. Making the coarse powder or irregular small pieces of organic fertilizer obtained by biological fermentation into spherical granular organic fertilizer is the key to solving the problem of large-scale popularization and use of organic fertilizer.
FPC will explain to you how the organic fertilizer production line makes organic fertilizer into pellets. The coarse powder or irregular small pieces of organic fertilizer after biological fermentation are characterized by high water content (30-40%) and looseness ( The bulk density is 0.3～0.4t/m3), and the fiber is much. The existing organic fertilizer in the form of coarse powder or irregular small pieces after biological fermentation is made into spherical granular organic fertilizer.
Some manufacturers use traditional discs or drums to granulate, and need to dry coarse powder or irregular small pieces of organic fertilizer (moisture content <15%) and crush them into very fine powder (greater than 100 mesh) . Then add the binder and inorganic fertilizer, and the addition amount of the binder and inorganic fertilizer in the organic fertilizer cannot be greater than 30%. Although this method can be made into spherical particles, the organic fertilizer in the processing process will be crushed by sufficient precipitation, then be granulated by adding water and then dried, repeated many times, so the processing cost is quite high. Moreover, due to the low density of organic fertilizer, the particle strength is low, which is not conducive to storage, transportation, and machine seeding.
disc granulator machine
There are also some manufacturers who first dry coarse powder or irregular small pieces of organic fertilizer until the moisture content is only 20-25%. Then, a flat die extrusion granulator or a pair-roll extrusion granulator is used to squeeze the dried organic fertilizer into columnar or oblate spherical particles. Although this method is more convenient to use, the fluidity is still not good, it is not suitable for machine broadcast, and the appearance is poor and the appearance is not good.
ShunXin roller pressing granulating equipment
Some manufacturers first use flat die extrusion granulatorto squeeze the coarse powder or irregular small pieces of organic fertilizer into short columnar particles (due to high water content and high fiber content, columnar particles also have a certain degree of plasticity). Then, it is polished to form spherical particles, and then the spherical particles are dried, cooled and sieved to obtain qualified particles. In this method, the raw materials do not need to be processed, the moisture sequence is reduced in steps, and the production cost is greatly reduced. However, this method also has some fatal weaknesses, that is, organic fertilizer is easy to arch, easy to block and easy to bond equipment, and at the same time, the output is small and the power consumption of the extrusion process is high.
Flat die granulator
Therefore, in summary, the organic fertilizer industry urgently needs to introduce a large-yield, low-energy compression granulating equipment to overcome the easy arching, easy blocking, easy bonding equipment, and small output of the traditional granulator. And the shortcomings of high power consumption in the extrusion process.
The roller extrusion granulator machine is the main equipment for making compound fertilizer, compound fertilizer and organic fertilizer compound fertilizer. It adopts the normal temperature extrusion process to extrude various raw materials at one time, with high ball formation rate and very little return material, so it is widely used. Moreover, the roller granulation equipment has reasonable design, simple operation, convenient maintenance, and stable operation. The most important thing is that its investment cost is the lowest compared to other pelletizers. The roller extrusion granulator is also suitable for a wide range of materials. It can not only process materials in the dry powder state such as ammonium chloride, urea, and ammonium phosphate, but also process other raw materials for organic fertilizer machines. It has a significant effect in reducing production costs and efficiency. And the price of such a practical double-roller extrusion granulator is about several thousand dollars.
