First, the granular material processed by the organic fertilizer double-die granulator has a smooth surface and moderate hardness. During the processing, it can better maintain the internal nutrition of the material. It integrates a feeder, a mixer and a granulator. While feeding evenly, it can also carry out secondary fermentation of the material. The feeder is equipped with a governor, which adjusts the feeding amount according to the dry humidity of the material during production, so that the host is not easy to get stuck. The main machine integrates the ring die and the flat die, which is equivalent to the work of two granulators.

Second, the organic fertilizer double-die granulator has uniform particle composition and neat shape. The pore size of the particle size can be divided into 05, 06, 07, 08, etc., users can flexibly choose according to their own production needs.

Third, the mold, stirring and conveying blades of the double-die granulator are all made of corrosion-resistant stainless steel. Thereby effectively increasing the output and reducing the loss of equipment.

Double Roller Granulator in Manufacturing

The following is an introduction to the correct use of the double-die granulator:

1. Fill the gearbox with 40# or 50# mechanical oil. If the temperature is low, add 70# or 90# gear oil before starting the machine;
2. Install the granulator smoothly, adjust the steering is normal, check whether the screws between the various parts are loose, pay attention to the gap between the pressing spoke and the mold in the season, the gap between the roller and the template is 0.1-0.3 mm, so that the machine It can be used after it is in a no-composite state and starts normally. The starting sequence is: 1, start the granulator; 2, start the feeder; 3, feed and adjust the speed of the feeder.
3. When the new double roller press machine is used for the first time, gradually add oily materials. The relay of chicken and duck is repeatedly squeezed to make the die hole lubricated and smooth, and then slowly add the materials to be processed and mixed for processing. If you feel that the resistance of the die hole is relatively large , When the output is low or no material is produced, the template can be repeatedly ground according to the method mentioned above, so that the die hole is lubricated and smooth before processing.
4. In the process of material processing, if there are more refined fibers, about 5% of water should be added. If there are more refined fibers in the mixture, the amount of water added can be appropriately reduced. Water will evaporate during the extrusion process. When adding compound fertilizer, attention should be paid to the chemical reaction of the material and the degree of dryness and wetness.
5. After the processing is completed, the feeder must be running at no load, and the host material cannot be accumulated. Pay attention to the minimum value of the current before it can be turned off. The correct sequence of shutdown is: stop feeding – close feeder – close granulator.

The above is the introduction of the use characteristics and correct use methods of the double-die granulator. You can refer to it. Only by mastering the scientific use method can ensure the high efficiency of production work and effectively prolong the service life of the equipment.

At present, the use of organic waste to produce organic fertilizer through biological fermentation has been rapidly developed, because it can realize the harmless and resourceful treatment of organic waste. However, most of the organic fertilizers obtained by biological fermentation are in the form of coarse powder or irregular small pieces, which are very inconvenient to use, especially unfavorable for large-area machine-sowing. Today, the FPC organic fertilizer manufacturer will explain how the organic fertilizer production line compresses and granulates the organic fertilizer.

The existing technologies for making the coarse powder or irregular small block organic fertilizer after biological fermentation into spherical granular organic fertilizer mainly include the following:

Double Rolloer Granulator for Sale in SX

• Some manufacturers use traditional disc or drum granulation, and need to dry coarse powder or irregular small pieces of organic fertilizer (moisture <15%) and pulverize it into very fine (more than 100 mesh) powder , and then add binder and inorganic fertilizer, and the amount of binder and inorganic fertilizer added in the organic fertilizer cannot be greater than 30%. Although this method can be made into spherical particles, because the organic fertilizer in the processing process will be first Sufficient precipitation is crushed, water is added to granulate and then dried, repeated many times, so the organic fertilizer processing cost is quite high, and due to the low density of organic fertilizer, the particle strength is low, which is not conducive to storage, transportation and machine sowing.
• There are also some manufacturers who first dry the coarse powder or irregular small pieces of organic fertilizer to a moisture content of only 20-25%, and then use a flat die extrusion granulator or a counter-roll extrusion granulator to dry the fertilizer. The organic fertilizer is extruded into columnar or flat spherical particles. Although this method is more convenient to use, the fluidity is not very good, it is not suitable for machine sowing, and the appearance is poor and the appearance is not good.

• There are also some manufacturers who extrude coarse powder or irregular small pieces of organic fertilizer into short columnar particles with a flat die extrusion pelletizer(due to high moisture and high fiber content, the columnar particles also have certain characteristics. Plasticity), then polished and formed into spherical particles, and then the spherical particles are dried, cooled and screened to obtain qualified particles. In this method, the raw materials do not need to be treated, the order of moisture is reduced, and the production cost is greatly reduced, but this method also has some fatal The weakness is that the organic fertilizer is easy to be arched, 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.

Therefore, in summary, the use of collision granulator to produce organic granular fertilizer has the advantages of low production cost, uniform product particle size, high strength, good fluidity, favorable for long-term storage and transportation, and suitable for machine sowing. That is to say, the performance of the products produced in this way is very good.

When the organic fertilizer production line is in operation, it is mainly divided into two parts: pretreatment part and granulation production. The following organic fertilizer making equipment manufacturer FPC will take you to understand each part.

Wheel type Compost Turner for Large Scale Composting

The pretreatment part is also called powder organic fertilizer processing equipment: animal manure composting turner, organic fertilizer pulverizer, drum screening machine and other equipment.

The granulation production part is further divided into: mixer, granular organic fertilizer maker, rotary dryer, cooler, drum screening machine, coating machine, automatic weighing and packaging machine. Through the organic fertilizer production line, the processing of livestock and poultry manure, straw rice husks, biogas residue sludge, kitchen waste and urban waste into organic fertilizer can not only reduce environmental pollution but also turn waste into treasure.

Cow Manure Granulation Machine

Since its establishment, FPC Organic Fertilizer Equipment Factory has continuously updated its products. With advanced equipment, exquisite craftsmanship and strict inspection and testing, it provides customers with high-quality products and has won unanimous praise from users. The products are exported to all parts of the country and abroad. The company’s products and quality have always been in a leading and dominant position in the same industry.

Organic fertilizer granulator internal structure

The roller extrusion fertilizer granulator machine is a kind of granulation equipment in the organic fertilizer equipment. Synchronized, opposite work.

The material is added from the feeding hopper, extruded by the rollers, demolded into balls, and passed through a pair of chains, sent to the crushing screen working room, screened and separated the finished particles, and then the returned material is mixed with the new material, and then granulated . With the continuous rotation of the motor and the continuous entry of materials, mass production can be realized.

1. The frame part of the roller extrusion granulator:

All the working bodies of the fertilizer press pelleting machine are all installed and fixed on the frame. The frame of the machine is made of medium carbon steel plate and channel steel welded. Through strict quality control and specific process requirements, the purpose of this machine is achieved. There are hoisting holes in the middle of the four corners of the rack for use in loading and unloading transportation.

2. The transmission connection part of the fertilizer roller extrusion granulator:

The motor drives the pulley, the V-belt and the reducer to make the machine head work. In addition, the sprocket and the chain form the transmission chain and transmit it to the crushing and separation working part. Among them, the transmission reducer and the working part of the machine head are meshed with nylon pin couplings to transmit and drive.

Second, the maintenance of organic fertilizer granulator

The pressing wheel of the organic fertilizer granulator is divided into two types: flat pressing wheel and inclined pressing wheel. Whether it is a flat pressure roller or an inclined pressure roller, the key points of maintenance are reasonable oil injection, timely cleaning, and clearance adjustment. The rationality of the oil injection of the pressure roller of the organic fertilizer granulator determines the use of the pressure roller and the pressure roller bearing. Life. The oil filling of the pressure roller is mainly reflected in the selection of lubricating grease, the oil filling method and the order of oil filling time.

Double Roller Granulator in Manufacturing

Good lubricating grease, correct oil injection method and accurate oil injection time are the key to the maintenance of organic fertilizer roller press granulator press wheel. Since the organic fertilizer granulator press roller is in direct contact with the material, adhesion and penetration are inevitable. Once the material enters the press roller, it will cause excessive wear and increase the probability of damage. The damage of the pressure roller and the bearing of the pressure roller becomes an effective means.

Maintaining a proper clearance with the equipment in the stopped state during the production process can reduce the wear caused by friction. Different materials and different density requirements also require a reasonable and cost-effective clearance.

The above maintenance of the organic fertilizer granulator press wheel must be strictly followed in the practical application of the organic fertilizer granulator. In addition, effective maintenance measures can also enable the pressure roller of the organic fertilizer granulator to exert a higher use energy. Generally speaking, the flat pressure roller can be repaired and used, and the cost of the inclined surface pressure roller is slightly higher.

In order to use organic fertilizer making equipment to create more economic benefits, we should first improve the efficiency from the production process. What aspects should organic fertilizer equipment manufacturers start from to improve granulation efficiency?

When using compound fertilizer equipment for granulation, a large amount of organic raw materials are required. Most of these organic substances are perishable substances or rotten substances, but most of them still maintain the prototype. Therefore, hammer crushing should be used first when making materials. The machine crushes the material and then puts it into the fermentation pair for fermentation, because these processes are all prepared for the granulation of the compound fertilizer equipment in the later stage.

Pan Type Fertilizer Pelletizing Machine

Therefore, it needs to be pulverized to the required fineness for granulation. These materials may have a lot of pungent odor during the process of pulverization and transportation. If measures are taken in advance, the decomposition of organic matter during fermentation of organic fertilizer raw materials will produce A large amount of pungent gas is mainly ammonia gas, so the fermentation workshop should be separated from the production workshop as much as possible. After the material is completely decomposed, the material can be transported to the compound fertilizer processing equipment by a screw conveyor, and the material enters the compound fertilizer equipment from the gold silo for extrusion and granulation.

1. According to the composition, fineness, viscosity, humidity, temperature and other characteristics of the powder, the moisture content of the powder should be controlled at about 30-28%.
2. Too much water content, too many balls, the surface of the ball is very sticky, and it is easy to block the screen surface;
3. How to preliminarily measure the volume of granulated water in the production process: a simple and practical method – hand feeling method: grab a material ball from the disk fertilizer granulator, the hand can be a ball, and it can be released by touching it with your fingers. In this way, there are many particles, high output, and it is not easy to block the screen surface.
4. Control the quality of various raw materials such as chemical fertilizers in strict accordance with the compound fertilizer formula.
5. It is strictly forbidden to use iron blocks, stone blocks larger than 10mm, and wood blocks larger than 10mm for raw material discharging and feeding. There are not many quality indicators of rice bran and rice sand, which seriously affect the yield.
6. The powder particle size used as compound fertilizer is 70-90 mesh.
7. Do a good job in technical training to improve the technical quality and operation skills of workers.

Organic fertilizer granulator-everyone knows that this name is closely related to the production of organic fertilizer. The organic fertilizer ball making machine is an important mechanical equipment for the production of organic fertilizer. Compared with other organic fertilizer equipment, the organic fertilizer granulator is irreplaceable. So what are the main advantages of the organic fertilizer granulator? Let’s give you a detailed description.

Cow Manure Granulation Machine

To be the best in organic fertilizer equipment, the organic fertilizer granulator should be ranked first. The organic fertilizer granulator is the latest technology developed by the Agricultural Machinery Research Institute for many years of compound fertilizer processing equipment design and production experience. The product has obtained the national utility model patent. It is used to granulate various organic matter after fermentation, breaking through the conventional organic matter granulation process. There is no need to dry and crush the raw materials before granulation, and the spherical particles can be processed directly by the ingredients, which can save a lot of energy. Its characteristic is that the produced particles are spherical. The content of organic matter can be as high as 100%, realizing the granulation of pure organic matter. Utilizing the feature that organic particles can grow up inlaid with each other under certain action, no binder is needed when granulating. The granules are solid and can be sieved after granulation, reducing the energy consumption for drying. The organic matter after fermentation does not need to be dried, and the moisture content of the raw material can be 20%-40%.

Pan Type Fertilizer Pelletizing Machine

Furthermore, it is a disk pan granulator, which adopts an overall arc structure, and the granulation rate can reach more than 93%. The pelletizing tray is provided with three discharge ports, which is convenient for intermittent production operations, greatly reduces labor intensity and improves labor efficiency. The reducer and the motor adopt flexible leather transmission, which can start smoothly, reduce the impact force of the buffer, and increase the service life of the equipment. The bottom of the pelletizing disc is reinforced with multiple radiant steel plates, which is durable and never deformed. The thickened, heavier, and sturdy base design does not require anchor bolts to fix, and it runs smoothly. The main gear of the granulator adopts high frequency quenching, and the service life is doubled. The granulation face plate is lined with high-strength fiberglass, which is anti-corrosion and durable. This surface has the advantages of uniform granulation, high granulation rate, stable operation, sturdy and durable equipment, and long service life. It is an ideal equipment for users to choose.

The above is an explanation of the advantages of the organic fertilizer granulator. You need to understand it carefully. It is precisely because of these effects that the production of organic fertilizer is guaranteed and the quality of organic fertilizer is guaranteed. Everyone needs to know.

For friends who are preparing to start production of organic fertilizers, there are many things that need to be done, such as project establishment, production plan, process selection, equipment purchase, plant construction, and there may be bidding matters. Since 2020, due to the rising price of raw materials, which has a greater impact on the price of equipment, many friends are very concerned about how much it costs to put into production an organic fertilizer equipment?

First of all, in the case of equipment purchase alone, the price of a set of organic fertilizer production equipment may range from tens of thousands to several million. There are many factors that affect the price of organic fertilizer equipment. Production capacity, raw materials, and equipment selection must also consider the rise and fall of equipment raw materials. Today, I will use two different customer production cases last year to explain the price of the equipment in detail and see which situation is suitable for you.

1. Simple configuration of organic fertilizer equipment to produce fermented organic fertilizer

If the organic fertilizer is produced on a small scale, commercial sales are not required, only the pre-fermentation process is required, and the subsequent deep processing is not required. At present, there are three forms of organic fertilizer fermentation equipment:

1. Choose an organic fertilizer fermentation tank.

Fermentation tank processing organic fertilizer is suitable for the conditions of strict environmental protection requirements and high fermentation aging requirements. At present, the use of fermentation tanks to process organic fertilizer can produce raw materials within 48 hours. The fermentation tank can be equipped with a deodorization system to completely solve the environmental pollution problem. It is not affected by the external temperature and environmental terrain, and can be produced at any time.

2. Adopt small trough type compost turning machine.

The trough-type manure compost turning machine runs stably, and can be changed by one turning-and-turning machine. It can handle multiple trough materials with large output and uniform turning and polishing. Most organic fertilizer processing plants are used. The small 2-meter trough-type turning and polishing machine is only priced at 5 thousand dollars.

3. Use self-propelled compost turning machine.

The self-propelled manure composting machine is divided into wheel type and crawler type. It is characterized by large processing capacity and free movement. It is suitable for organic fertilizer dumping operations in a wide area, and is suitable for organic fertilizer processing plants that do not want to carry out a large amount of civil engineering. The price of the type turning machine is about 10,000 dollars.

2. Simple configuration of equipment for producing powdered organic fertilizer

The production of powdered organic fertilizer is finely pulverized after the fermentation of organic fertilizer. The required equipment: fermentation dumper, forklift silo, semi-wet material shredder, drum screening machine, automatic packaging is called powder organic fertilizer. This low-end configuration of powder organic fertilizer production equipment can be realized at a price of about 30,000-90,000 dollars.

3. Equipment for producing granular organic fertilizer

The production process of granular organic fertilizer is relatively complete and complicated at present, and it is also based on continuous fermentation process and powder organic fertilizer processing. Therefore, the required equipment is relatively more, including fermentation machine, forklift silo, semi-wet material crusher, horizontal mixer, organic fertilizer granulator machine, dryer, cooler, drum screening machine, fertilizer film coating machine and automatic packaging machine. When the process has special needs, dynamic ingredients are also needed. The price of a small complete set of equipment is about $100,000-$140,000.

For professional fertilizer processing enterprises, the production capacity requirements are relatively large. For an organic fertilizer production line with an annual output of 50,000 tons, the equipment price is between $90,000 and $150,000. Such a price range is a reasonable range that takes into account the different needs of different customers.

The above is the approximate price of organic fertilizer production equipment. Since 2021, the price of metals has soared, pushing up the price of equipment, and the specific situation should be based on real-time quotation.

However, in the actual process design, because the production capacity requirements of each project, the ground processing site, and the configuration of the entire set of organic fertilizer production equipment are not fixed, there are often many different situations, so the specific price depends on the situation. FPC will generally provide customers with process design, equipment processing and installation, and production training for free according to the actual situation of the customer. Let customers achieve mass production without any worries.

The dry-free extrusion granulation process of the pair-roller extrusion granulator has a wide range of applications in powder processing granules. Its characteristic is that it does not need to humidify or heat the material, and it can directly process the particles. It can be used for the processing of organic and inorganic fertilizer particles, and also for the processing of feed particles.

Utilizing the non-drying extrusion granulation process, no waste water or waste gas is discharged outside during the production process, and it will not pollute the environment. The extrusion granulation process is short, the operation is simple, and it is convenient to realize the automatic control of production and improve the production efficiency. 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.

Double Roller Powder Granulator

The five process stages of the production process of organic fertilizer and inorganic fertilizer by roller extrusion granulation

1. Add the qualified raw materials into the mixer according to the ratio requirements and mix them evenly.
2. It is transported to the disc feeder, and the metallic substance in the material is removed during the transporting process.
3. The material in the disc feeder evenly enters the extrusion granulator. The material is forced to pass between the two pressure rollers to be squeezed into flakes. The flakes are broken into pieces by the coarse crusher under the pressure rollers. Sieving. The materials on the screen continue to be crushed and sieved.
4. The semi-finished products are transported to the finished screening machine. The fine particles after screening are returned directly to the disc feeder. The large particles are crushed by the pulverizer and then returned to the disc feeder.
5. The qualified products after screening are transported to the automatic packaging scale for weighing, packaging, and storage.

Double Rolloer Granulator for Sale in SX

The non-drying pair-roll extrusion granulator has the following characteristics in the production of granules:

1. 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.
2. No waste water or waste gas is discharged outside during the production process, and it will not pollute the environment.
3. The extrusion granulation process is short, easy to operate, easy to realize automatic production control, and improve production efficiency.
4. 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.
5. 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.
6. The product has uniform particle size distribution, no segregation or agglomeration.
7. The shape of extrusion granulation product is uniform and not round. Usually, if you need a more round product, you need to further shape the particles.

Double Roller Granulator in Manufacturing

The non-drying extrusion granulation process basically uses a pair-roll extrusion granulator as the main machine of the granulation. FPC has rich experience and good design concepts in the process design of the double-roll extrusion granulator. It has made considerable progress in the upgrading of equipment. Relatively speaking, the granulation rate is high and the return material is low. It is the most popular non-drying extrusion in the market. Pressure granulator process equipment.

High-temperature composting technology generally uses aerobic tank fermentation to make compost, and uses a tank turning machine to ferment and turn the pile. For large yields, a roulette turning machine can be used to ferment and turn. It can also be decomposed by strip-chop fermentation, using a crawler turning machine or walking type turning machine. It can ensure enough high temperature to kill the parasites and roundworm eggs, and kill the vegetative cells of pathogenic bacteria, and kill weed seeds, and consume the energy such as carbohydrates in the materials as much as possible, so as not to be applied to the soil in the future. After the middle, it causes undesirable phenomena such as burning roots and seedlings. At the same time, the high temperature has the conditions to consume as much as possible the crude fiber in the feces and the hydrocarbons in the straw. If the hydrocarbons in the crude fiber and straw are not removed, after applying this fertilizer to the soil in the future, one will burn the roots, and the other is because the carbon-nitrogen ratio of this fertilizer is too high, which will cause a large number of microorganisms to heat up. At the same time, it will compete for the nitrogen source in the soil to balance the carbon-nitrogen ratio, which will result in an unfavorable situation of competing with plants for fertilizer, resulting in slender roots and seedlings. At the same time, the use of a trough-type compost turner for fermentation and aerobic fermentation can ensure rapid fermentation and keep farmers in the middle of the two crops. In a short period of time, the straw decomposing process is fully completed.

Wheel type Compost Turner for Large Scale Composting

Fermentation of organic fertilizers is to use chain plate type compost turning machines that can process livestock and poultry manure and strip-type crawler turning and throwing machines to ferment and decompose. The second is to use aerobic fecal fermentation tank for fermentation, which has a short operating period and high processing efficiency. The heat generated by the fermentation in the fermenter rises, which can preheat the upper layer of feces and facilitate the flow of air and the supply of oxygen. The fermentation tank is divided into multiple layers, and each layer can be fermented. After the manure is put into the fermentation tank, the manure is transferred and turned over by the turning of the flap. The operation is simple, the energy consumption is low, and the floor space is small and the maintenance is convenient. The third is that the flap is provided with vent holes, and the flap is directly left with fine slits. The bottom of each layer of fermentation chamber is arranged with air pipes, which improves the aeration capacity, reduces the energy consumption of the fan, and makes the air distribution more uniform. However, it is difficult for the staff to understand the processing conditions of high-temperature fermentation of livestock and poultry manure from the outside. The livestock and poultry manure after high temperature treatment can be slowly dropped to the top of the transfer truck or on the receiving conveyor to complete the automation of the device, and the waste gas generated during fermentation is processed by a dedicated waste gas processor. The exhaust gas treated by the processor meets the emission requirements. The fecal material that has been fermented and decomposed needs to be thoroughly decomposed in the aging field. The aging field is also called the secondary fermentation plant. The secondary fermentation generally takes 5-7 days, and the secondary fermentation time can also be determined according to the production volume. The maximum time should not exceed 20 days. The white mycelium inside the fermentation product and the aroma of distiller’s grains will be produced at the same time. The secondary fermentation field can also be used as a raw material storage field. The pellets made of raw materials that are not fermented and decomposed are easy to swell after bagging.

Granular and powder organic fertilizer production line

Next, the fermented raw materials are crushed, and a special crusher can be used to crush to the granulation requirements, generally 0.5-0.08mm (24-50 mesh). At this time, the crushed raw materials are put into a horizontal mixer for mixing, and humic acid can be added or nitrogen, phosphorus, potassium, reinforcing powder, and organic matter can be added to meet the requirements of the formula and meet the national standards. The agitated raw materials are crushed by a chain pulverizer and then sent to an organic fertilizer granulator for granulation. During granulation, the angle of the granulator and the pressure of the water supply can be adjusted according to the required particle size to form balls, and the ball formation rate can reach 95%.

fertilizer rotary drum granulator

At this time, the manufactured particles are sent to the dryer for drying. The length and diameter of the dryer are determined according to the output. The retention time of particles in the dryer is generally about 30-40 minutes. The particles are dispersed in the dryer through the lifting device to fully absorb heat. The heat is generated by the hot blast stove and sent to the dryer through the induced draft fan to dry the particles, suck away the moisture, and enter the dust removal room. After the gas entering the dust removal room is processed, it meets the air emission requirements, and then is discharged into the atmosphere. This meets the requirements of air environmental protection. At the same time, the dried semi-finished product is sent to the cooler for cooling. The feed temperature is generally 60-80 degrees, and the temperature of the cooled material is generally about 30 degrees. Then the cooled semi-finished product is sent to the sieving machine for screening For classification, the particle size of the finished product is between 2.5-5.5, and the finished particles after sieving are sent to the coating machine.

complete organic fertilizer production line

Send the large over-standard particles and small particles into the chain-type powder mill after stirring to be crushed and re-granulated. Color to achieve customer satisfaction, and the coating agent contains certain nutrients to achieve slow-release purpose). The particles sent into the finished product warehouse are weighed and packaged by an automatic weighing and packaging machine. When weighing, they are bagged according to their own set weight. After sealing, the finished organic fertilizer can be sent to the finished product warehouse or shipped out of the factory.

Detailed production process

Speaking of the small-scale organic fertilizer production line, many people may think that it is the farmer’s homemade organic fertilizer processing method that pollutes the surrounding air and groundwater, but this is not always the case. The reason for this concept is that people’s classification of large, small, and medium-sized organic fertilizer production lines is not clear. According to the general classification standard of organic fertilizer equipment manufacturers. Organic fertilizer production lines with an annual output of less than 20,000 tons are all small-scale organic fertilizer production lines. However, the small-scale organic fertilizer processing technology that pollutes the air and groundwater in the family workshop is only used for small-scale farms or family breeding, and the output is more than 3,000 tons a year. It is caused by no professional rancid treatment and anti-seepage pollution groundwater measures. This will gradually be eliminated. The qualified small-scale organic fertilizer production line covers an annual output of 3,000 tons-an annual output of 20,000 tons, and requires investment in professional organic fertilizer equipment-organic fertilizer turning machines, grinders, granulators, etc. Let’s talk about the production method of this environmentally friendly small-scale organic fertilizer production line.

Powder organic fertilizer production line

The small-scale organic fertilizer production line has the characteristics of convenient materials, low cost, fast recovery cost, low energy consumption, good income-generating efficiency, no pollution, and high organic content. It is an ecological fertilizer processing equipment. Create conditions for improving the soil environment, improving the living environment of farmers and soil water pollution.

The process of the environmentally friendly small-scale organic fertilizer production line generally uses tank fermentation or trough fermentation, and the other is advanced biogas production, which is then fermented into organic fertilizer. This is a relatively common advanced technology for organic fertilizer processing in the market.

Granular and powder organic fertilizer production line

The advanced process methods of the small-scale organic fertilizer production line are as follows:

1. Pile livestock and poultry manure and other materials, household garbage, sludge and other fertilizer base materials on a flat ground in a chopped shape. (The trough turning machine directly puts the material into the trough), the pile width is equal to the turning pile width of the equipment, the height is as high as possible, and the length is as long as possible, such as 50 meters, 100 meters, etc., the ground should be flat, cement, The land can be used (as long as it is level and has a certain degree of hardness), 5-6 acres of space is required for every 10,000 tons produced, and the area ofthe trough turning machine will be relatively small).
2. Sprinkle the piled up livestock and poultry manure and other materials, domestic garbage, sludge and other fertilizer base materials on the biological fermentation inoculants (this unit provides technology and fermentation inoculants).
3. Use a windrow or trough turning machine to mix straw, livestock and poultry manure and other materials, household garbage, sludge, (water content should be 50%-70%), fermentation bacteria, etc., and mix, 3- It can deodorize in 5 hours. In 16 hours, the temperature is raised to 50 degrees. When the temperature reaches 55 degrees, the pile will be turned again to increase oxygen. Afterwards, whenever the temperature of the material reaches 55 degrees, it will start to stir, which has the effect of uniform fermentation, oxygenation and cooling. Repeat the latter process until completely decomposed.
4. If the moisture content of livestock manure and other materials, domestic garbage, sludge, etc. is too high, you can add organic, relatively dry auxiliary materials that can absorb moisture or use the method of recirculation to put the last dried fertilizer underneath to form a chop. Put the livestock and poultry manure and other materials, domestic garbage, sludge, etc., with a large water content in the middle, so that the water on the top can seep to the bottom before being dumped.
5. The general fertilizer process takes 7-10 days. Due to the different climates in different regions, it may take 10-15 days before the material will be completely decomposed, achieving no odor, no germs, eggs, weed seeds, and high humus content. , Increased potassium content, etc. Powdered organic fertilizer is made.
6. The powdered organic fertilizer can then be put into storage and sold by crushing, sieving, screening, automatic fertilizer packing machine and other equipment.

If it is to make powdered organic fertilizer, it can be sold on the market after the above-mentioned preliminary process is completed. As a commodity sales, considering the inventory time and fertilizer efficiency maintenance, etc., it needs to be further processed in the above process and processed into granular organic fertilizer.

When processing granular organic fertilizer, the process of the small-scale organic fertilizer production line adds the following process flow to the above description: ① Use the organic fertilizer granulator to process the particles into 3mm-5mm-8mm and other particles; ② Screening by the sieving machine; ③ After screening, the particles that meet the specifications enter the lower-level process, and those that do not meet the requirements are returned to the pulverizer for reprocessing and re-granulation; it should be noted that the first-time granulation rate of FPC organic fertilizer granulator reaches more than 95%; ④ meets the requirements Transfer to the dryer and cooler for drying and cooling; ⑤ In order to maintain fertilizer, the particles need to be coated, which is the coating process of the film coating machine; ⑥ The coated particles are transported to the automatic weighing and packaging machine for packaging; ⑦ Storage.
