Organic fertilizer is a natural fertilizer, but also an important part of sustainable development of human agriculture, so people pay more and more attention to the production of organic fertilizer. The following introduces the main production process of organic fertilizer production equipment and the relevant situation of organic fertilizer fermentation equipment.

Organic fertilizer production process is generally divided into: fermentation, crushing, ingredients, mixing, molding, drying, cooling, screening, packaging. Of course, some high-end fertilizers will add slurry to make the fertilizer look more beautiful.

1. The first is the fermentation equipment. Most organic fertilizer manufacturers will use the composting fermentation. The key point of composting fermentation is the strain. Only when there are good strains can we get high-quality organic fertilizer. Then there is the crushing equipment. The more commonly used crushing equipment in the organic fertilizer industry is the chain crusher. 

2. Then there is the batching equipment. The batching equipment is divided into manual batching scale and computer batching scale. As the name implies, it is manual weighing equipment and computer automatic weighing equipment. According to the size of the manufacturer and the difficulty of ingredients, the equipment suitable for them will be selected. Here we mainly talk about the computer batching scale. The computer batching scale can evenly configure several or more kinds of different raw materials and trace elements. It can also be seen that the development of electronic products in China is very rapid. Followed by mixing equipment, organic fertilizer industry in the more commonly used mixing equipment is the disc mixer.

3. Focus on the granulation equipment, which is divided into disc granulator machine, rotary drum granulator, flat die pellet mill, ring die pelleting machine and organic fertilizer granulator. According to the characteristics of different raw materials, different granulation methods should be selected. Screening machines and packaging machines are general equipment and do not need to be discussed. These are the components of the organic fertilizer production line equipment.

Improving application efficiency: Granular fertilizers can be directly applied to the soil through mechanical fertilization equipment, improving the efficiency and uniformity of fertilization.

Controlled release: The dissolution and nutrient release rate of granular fertilizers are usually slower than that of powdered fertilizers, which helps plants absorb nutrients more evenly.

Easy to store and transport: Granular fertilizers have a small volume, large weight, and are not easily scattered, making them easy to transport and store over long distances.

Improving market value: Granular organic fertilizers have a cleaner appearance, are easier to measure and sell, and enhance the product’s market competitiveness.

Reducing environmental pollution: Through granulation, the loss of fertilizers during storage and transportation can be reduced, reducing environmental pollution.

Adjusting moisture content: During the granulation process, the humidity of the finished product can be controlled by adjusting the moisture content of the raw materials to meet the requirements of subsequent processes.

Adding slow-release materials: During the granulation process, slow-release materials such as sulfur coatings can be added to organic fertilizers to control the rate of nutrient release.

Improving the consistency and uniformity of fertilizers: The granulator ensures consistency in the size and shape of fertilizer particles for each batch, improving the uniformity of fertilizers.

Enhancing the functionality of fertilizers: During the granulation process, other functional substances such as microbial agents, growth regulators, etc. can be added to organic fertilizers to enhance their functionality.

Meeting specific application requirements: Some specific agricultural applications may require granular fertilizers of specific sizes or shapes, and the granulator can be adjusted according to these requirements.

The role of fertilizer granulator in organic fertilizer production line is not limited to changes in physical form, but also includes improvement of fertilizer performance and expansion of fertilizer function. It is an indispensable key equipment in the organic fertilizer production process.

Production process of organic fertilizer for manure treatment in livestock and poultry farms

Process flow of organic fertilizer production line for manure treatment in livestock and poultry farms

In livestock and poultry farms, manure treatment is a crucial step, and the production of organic fertilizer is one of the important methods for converting these manure into valuable resources. The process flow is mainly divided into four steps: collection, separation, composting, and fermentation.

The first stage is the collection phase, where livestock and poultry manure is effectively collected and preliminarily separated. It is possible to separate livestock and poultry manure from urine through a centralized collection and separation system to reduce the generation of ammonia and odor, and improve subsequent treatment efficiency.

Then comes the composting stage, where the separated animal manure is sealed and stored, and organic waste is properly organized and stacked, supplemented by ventilation equipment to control temperature, humidity, and oxygen supply, accelerating the decomposition process of organic matter. During this process, it is important to maintain appropriate humidity and ventilation to avoid the generation of odors and harmful gases.

Finally, in the fermentation stage, after the completion of composting, the compost is subjected to secondary composting fermentation to further enhance the stability and efficiency of the fertilizer. This process requires attention to reasonable moisture control and temperature regulation to ensure the full decomposition of organic matter and the killing of harmful microorganisms.

Organic fertilizer provides organic matter to the soil, thereby providing the necessary nutrients for plants and helping to establish a healthy soil system, rather than destroying it. Therefore, organic fertilizers contain huge business opportunities, and with the gradual restrictions and prohibitions on the use of fertilizers by most countries and relevant departments, the production of organic fertilizers will become a huge business opportunity.

Most organic raw materials can be fermented into organic compost. In fact, after crushing and screening, organic fertilizer compost becomes high-quality and saleable powdered organic fertilizer.

Mixed fertilizer raw materials such as urea, ammonium phosphate, potassium chloride, etc. are transported to the storage silo by bucket elevator and belt. The number of storage bins, the complexity of metering and mixing techniques, is related to the number of components in the product formulation.

2. extrusion

The mixed fertilizer mixture is extruded by a roller extruder, the principle of which is to shape the material by extrusion. The mixed material is fed into the gap between the two oppositely rotating roller shafts through a vertical screw feeder. During the extrusion process, the pressure of the material gradually increases. When the gap between the two shafts is small, The material is relatively compressed, and then gradually decreases until it reaches 0.

3. Crushing and grading

The slabs formed in the double roller granulator  are further broken up and classified to the desired particle size.

4. Polishing and finishing

Typically, the final product undergoes one or two steps of polishing.

The working principle and granulation process of the roller extrusion granulator

fertilizer granulator May 8, 2024

The roller squeezing granulator is a commonly used fertilizer granulation equipment, especially suitable for the granulation production of organic and compound fertilizers. The following is a brief introduction to the working principle and granulation process of the roller extrusion granulator:

operational principle

Extrusion molding: The core part of the roller extrusion granulator is composed of a pair of relatively rotating pressure rollers, which have grooves on the surface. When the material is fed between the two rollers, it is compressed to form a strip shape.

Shear cutting: After the extruded strip material passes through the pressure roller, it is usually cut by a fixed or rotating tool to form the required length of particles.

Adjustment control: By adjusting the gap and speed between the pressure rollers, the size and shape of the particles can be controlled.

Granulation process

Raw material preparation: Firstly, suitable raw materials need to be prepared, such as powder of organic fertilizers or mixtures of compound fertilizers.

Moisturizing and mixing: In order to improve the granulation efficiency, the raw materials usually need to be moistened and mixed with an appropriate amount of water and binder to improve their plasticity.

Conveying and feeding: The mixed materials are uniformly fed into the feeding area of the roller squeezing granulator through conveying equipment.

Squeezing: The material is compressed into strips under the high pressure of the pressure roller, and excess water is squeezed out.

Cutting: The extruded strip material is cut or cut into particles of the desired length.

Drying: Newly formed wet particles contain high moisture and require drying treatment through drying equipment to reduce moisture content, improve particle hardness and stability.

Screening and grading: The dried particles are screened through screening equipment to remove particles that do not meet the requirements and ensure product quality.

Cooling: The screened particles usually require further cooling to ensure their stability during storage and transportation.

Packaging: Finally, the qualified granular fertilizer is automatically weighed and packaged before leaving the factory.

The roller extrusion granulator has been widely used in the field of fertilizer granulation due to its advantages of high efficiency, energy saving, and strong adaptability. By optimizing process parameters and equipment maintenance, the production efficiency and product quality of fertilizer particles can be effectively improved.

The process and price of producing organic fertilizer from livestock and poultry manure

fertilizer granulator May 8, 2024

Powdered organic fertilizer is commonly used to improve soil and provide the nutritional value components required for crop growth. When they enter the soil, they can also be quickly decomposed and release nutrients quickly. Due to the slower absorption rate of powdered solid organic fertilizers, powdered organic fertilizers have a longer storage time than liquid organic fertilizers. The use of organic fertilizers greatly reduces damage to plants themselves and soil environment.

The process flow of producing organic fertilizer from livestock and poultry manure:

1. Raw material ratio: Various animal feces such as chicken manure, pig manure, cow manure, biogas residue, or fermentable and fertilizer effective raw materials are prepared in a certain proportion;

2. Raw material mixing: Mix the prepared raw materials evenly to improve the overall uniform fertilizer efficiency of the fertilizer particles;

3. Raw material granulation: The evenly mixed raw materials are fed into a fertilizer granulator for granulation;

4. Particle drying: Feed the particles made by the granulator into the fertilizer dryer to dry the moisture inside the particles, increase their strength, and facilitate storage;

5. Particle cooling: The temperature of the dried fertilizer particles is too high, making them prone to clumping. After cooling, they are easy to pack, store, and transport;

6. Particle classification: The cooled particles are classified, and the unqualified particles are crushed and re granulated to screen out the qualified products;

7. Finished product coating: Coating qualified products to increase the brightness and roundness of particles;

8. Finished product packaging: Bag the finished product particles and store them in a ventilated place.

The above are the process steps of the organic fertilizer production line for the treatment of livestock and poultry manure. Of course, the specific operation also involves different processes and equipment choices, which need to be adjusted according to the specific site and actual situation. 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. You need to consider factors such as equipment power, production capacity, automation level, and additional functions. For some special equipment or high-end large-scale production lines, the price may be higher. It is recommended that you conduct market research and communicate with multiple suppliers before making a purchase to ensure that you can obtain the most suitable production line for your needs and budget.
