Introduction to the Steps and Precautions of Organic Fertilizer Production

  1. 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.

  1. 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.

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.

  1. 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.

  1. 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.

How to Extend the Service Life of Organic Fertilizer Granulator?

The most commonly used and most important equipment in a complete organic fertilizer production line is the organic fertilizer granulator. As we all know, the equipment has its own service life, but some people can use the same equipment for many years, but some People can’t use it for a long time, mainly because everyone has different operating methods. More importantly, they don’t pay attention to the maintenance of equipment. So how should the organic fertilizer granulator be maintained?

  • The operator should pay attention to regularly check the components that are easily worn out in the structure, and observe whether the degree of wear is not serious or very serious. If it belongs to the latter, it should be replaced immediately to prevent accidents caused by persistent use.
  • As for the plane of the bottom frame where the movable device is placed, pay attention to maintaining sanitation and remove dust and other materials in time to prevent the movable bearing from moving smoothly on the bottom frame when the pelletizer equipment encounters unbreakable materials, which may cause serious accidents.

  • Good lubricating oil is very helpful to bearing life. Therefore, the operator must ensure that the injected lubricating oil is clean and has good sealing performance.

As long as you can always adhere to the above four points, you can greatly increase the service life of your pelletizing equipment, and the performance of the equipment can always be stable and efficient.

How Does the Organic Fertilizer Production Line Make Organic Fertilizer into Pellets?

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.

What Is the Difference Between Dry Granulation and Wet Granulation?

We often receive calls from many customers to inquire about matters related to the organic fertilizer granulator, and it is difficult for many customers to distinguish what kind of granulation method they need. The difference of the granulation method is to choose the corresponding suitable granulation method according to the use requirements of the material. It is mainly divided into two categories: dry method and wet method:

ShunXin roller pressing granulating equipment

Dry granulation

Mainly refers to products with relatively low moisture content. Generally, moisture content below 10% is a zero boundary value. (There are also very few materials that can reach 16%, such as some materials that only contain crystal water.) Dry granulation produces mostly irregular particles (such as common granular potash fertilizer) or, more generally speaking, like small gravel The sub-shapes are similar. With the current domestic industrial upgrading and environmental protection requirements becoming more and more stringent, many chemical and building materials powders need to be made into particles.

Disk Pelletizer for Poultry Manure Granulation

Wet granulation

There are also many equipment and methods in wet granulation for materials whose main indicator moisture is above 20%. Such as: plate granulation, roller granulation, screw granulation. The granulation methods used many years ago have been continued. After increasing the use environment and processing requirements of different materials, the continuous improvement has also made considerable progress. For example, the relatively popular organic fertilizer granulation in recent years, the particle size of these particles is between 1mm-6mm, and the above methods are used.

In the organic fertilizer granulator, dry granulation has lower energy consumption than wet granulation and is more environmentally friendly. It does not need to be dried, and does not add water and binder, so the material properties will not be changed. This is also the difference between dry granulation and wet granulation. Dry granulator machine is more suitable for industrialized mass production.

There is also a case that some materials require relatively small particle size, and products between tens of mesh and 100 mesh can also be reduced by airflow, spray, and flash drying.

Characteristics And Price of the Roller Extrusion Granulator

Double compression roller granulator

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.

Exactly What Does A Fertilizer Production Line Do?

The production line for NPK fertilizer completes all the following steps: – Crushing – Batching – Granulating – Mixing – Drying – Cooling – Screening – Coating – Packing

In short, these machines are made to lessen the production process if you make the entire NPK fertilizer manufacturing process better and faster. Consequently the one thing that you will want to do is to secure a a certain granulator for your personal fertilizer manufacturing plant. The granulator you will want may be the double roller extrusion granulator.

This particular granulator machine utilizes the technology of dry granulation to help make the fertilizer granules. It is ideal for using air to dry the pellets. The pellets which are created from this machine will not be full of temperature.

Put simply, these pellets do not need to be cooled and dried through the machines. In addition, this process eliminates the requirement for liquids or other sorts of binders. When binders are eliminated, the fertility and purity in the final product is a lot better.

Problems needing attention in the producting line of organic fertilizer

1. The risk in the process of fermentation and comminution of organic fertilizer production line mainly comes from the equipment. Such as the use of shredders, forklifts and other machinery, the need for eye and ear protection and prevention.

When using special stacking equipment, it is necessary to comply with the relevant regulations. Some dumpers contain high-speed rotary flail knives, and people and animals in contact with them should be well protected. When the mixed swing knife rotates through the stack, the material in the stack will be thrown out and become a risk factor. The equipment operators on site must understand and have protective measures.

2. Another kind of problem in the process of organic fertilizer composting is health. Animal manure, municipal sludge and other waste materials contain some pathogenic bacteria, and some of them are pathogenic to human beings.

The conventional simple prevention and control method is to let workers wear dust masks during operation and wash hands when contacting with raw materials. Ventilation measures shall be taken in places with dust, peculiar smell, harmful and toxic gases, and ventilation facilities shall be in good condition.

Four Methods of Temperature Control for Organic Fertilizer Drying Equipment

The drying efficiency of drying equipment in organic fertilizer production line is more important to the firing temperature. The change of firing temperature directly affects the drying quality, energy consumption and refractory brick life, so it is very important to strictly control the firing temperature.

But we will find that the firing temperature will always change.
If the firing temperature becomes lower, the feeding amount of the dryer should be adjusted to reduce the material. The range of reduction is based on the predicted range of temperature reduction. According to the variation of the feeding amount and the situation in the dryer, the corresponding air and coal consumption should be adjusted in time.

When the firing temperature becomes higher and the feed rate is at a higher level, the coal should be reduced first. The extent of reduction depends on the temperature of the industrial dryer has increased, rather than rush to feed. Only to find out the reasons for the change of the firing temperature of the drying equipment, and solve it pertinently. In addition, timely report to the superior in case of any change of temperature.

(1) Sealing control of dryer. It can be partially sealed, integrally sealed or closed chamber, etc., and the dust producing point can be sealed with a sealing cover, which can greatly reduce the material scattering and dust.

(2) Eliminate the height potential energy difference of dryer. This is the main reason of dust spilling. The elimination of height potential energy difference is caused by powder drop of hopper, protective cover and chute of handling equipment. We should try our best to reduce the fall and the inclination angle of the chute. Some airtight chambers are better to cause negative pressure, which is conducive to the collection of dust.

(3) The transportation equipment with good sealing performance shall be used to reduce the height difference and inclination angle of discharge material flow, and the flow separation facilities shall be set as far as possible. It can not only enhance the configuration flexibility and efficiency of each operation room, but also reduce the scattering and dust.

(4) Use the exhaust system. In order not to let the dust bring more pollution, we can also remove the indoor dust through the exhaust system, that is to remove the indoor exhaust gas.

Attentional Things in Deep Processing of Organic Fertilizer Production Line

Scientific and reasonable fermentation can promote disease resistant organic matter in the fermentation process, accompanied by a large number of microorganisms breeding and a series of complex biochemical reactions. Microorganisms produce a large number of metabolic substances in the breeding process, such as hormones, antibiotics, autoimmune substances, which can promote the rapid growth and development of crops, inhibit the spread of soil diseases, and improve the ability of crop disease resistance.

1. After the initial processing of the organic fertilizer production line, the material can be screened by the screening machine to remove the large materials and animal hair. This is conducive to deep processing granulation.

2. When adding NPK trace elements, organic fertilizer equipment mixer should be used for mixing to avoid uneven nutrient elements, resulting in insufficient or excessive content of some particles and failure of sampling test.

3. When the processing capacity of the organic fertilizer production line exceeds 20000 tons, fast drying and cooling should be adopted as far as possible to speed up the production of organic fertilizer and improve the production efficiency of the production line. After drying and cooling, the hardness of the particles can be strengthened, and the moisture in the particles can be quickly evaporated, which is conducive to later bagging and preservation, and is not easy to deteriorate.

4. Organic fertilizer production line equipment is used for secondary screening after particle processing. Unqualified particles and powders will be returned to crushing again and used as powdery organic fertilizer after crushing. Qualified granular organic fertilizer, into the coating machine, add moisture-proof agent, slow-release agent, etc., this can increase the gloss of the particles, improve the appearance of the product; also can avoid in the process of transportation, storage moisture, deterioration.x
