The organic hypertrophy obtained by biological fermentation is mostly coarse powder or irregular small pieces, which is inconvenient to use, especially to machine seeding in large area. Making these organic fertilizers into spherical granular organic fertilizers is the key to promote the use of organic hypertrophy areas.

The coarse powder or irregular small pieces of organic fertilizer after biological fermentation are characterized by high moisture, loose and many fibers. The existing technologies for preparing spherical granular organic fertilizer from coarse powder or irregular small pieces of organic fertilizer after biological fermentation are mainly as follows:

1. Some manufacturers use the traditional disc fertilizer granulator or rotary drum granulator, need to dry and crush the coarse powder or irregular small pieces of organic fertilizer into very fine (more than 100 mesh) powder, and then add binder and inorganic fertilizer, and the amount of binder and inorganic fertilizer in organic fertilizer can not be more than 30%. Although this method can make spherical particles, due to processing The organic fertilizer in the process will be first crushed by sufficient precipitation, then granulated with water and then dried, repeated for 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;

2. Some manufacturers first dry the organic fertilizer until the moisture content is only 20-25%, and then use the flat die extrusion granulator or the double roller granulator to extrude the dried organic fertilizer into columnar or flat spherical particles. Although this method is more convenient to use, it is not suitable for machine sowing, and it has poor appearance and poor sales;

3. Some manufacturers will first use the flat die extrusion granulator to extrude into short cylindrical particles (due to high moisture content and high fiber content, the columnar particles also have certain plasticity), then polish and shape them into spherical particles, and then dry, cool and screen the spherical particles to obtain qualified particles. In this method, raw materials do not need to be treated, the moisture sequence is reduced step by step, and the production cost is greatly reduced, However, there are some fatal weaknesses in this method, that is, organic fertilizer is easy to arch, block and bond, with small output and high power consumption in extrusion process. 

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.

Organic fertilizer production lines are generally divided into two categories, one is powder organic fertilizer production line, and the other is granular organic fertilizer production line, which is powder organic fertilizer production line.

1. Granular organic fertilizer is generally better than powdered organic fertilizer. Fertilizers with low water solubility should be crushed into small particles to ensure that they dissolve quickly and efficiently in the soil and are absorbed by plants. The control of organic fertilizer particle size is very important for the storage and transportation of fertilizers. Good granulation can make organic fertilizer not easy to agglomerate and have better transport performance. The organic fertilizer production line can add some inorganic ingredients, and the npk production line can also be used to improve the fertility of the organic fertilizer, while the powdery fertilizer can easily absorb moisture and agglomerate if inorganic ingredients are added.

2. The production of powdered organic fertilizer mainly includes livestock and poultry manure or domestic waste, sludge, wine tank, biogas residue and other alcohol and decomposed. The basic process of powdered organic fertilizer is dehydration, drying, fermentation, crushing, mixing and packaging. After these steps, the processing and production of powdered organic fertilizer is completed.

3. Granular organic fertilizer is not as simple as powdered organic fertilizer, and its production process requires further processing. Organic fertilizer granular fertilizer needs to go through the steps of alcohol growth, dehydration, drying, deodorization, crushing, mixing, mixing, double roller granulator, high temperature, cooling, packaging, etc. High temperature is required in the granulation process. In the process of producing granular bio-organic fertilizer at high temperature, powdered organic matter should be granulated first, and then microbial inoculants should be sprayed on the surface of the granules, which can not only ensure the granulation of organic fertilizer, but also ensure the survival rate of bacteria.

The advantages of powdery organic fertilizer

Powdery organic fertilizer is the organic fertilizer without granulation and drying, which occupies the absolute main market share. Compared with granular bio organic fertilizer, powdered organic fertilizer has the advantages of small investment, low production cost, less nutrient loss in the process of processing, low price and less ecological pollution, which is generally accepted by planting parks and fruit and vegetable bases. However, the powdered organic fertilizer has not been treated by disc granulator, and its shape is not beautiful enough, so it is not suitable for machine seeding and application.

Powder organic fertilizer production equipment

The production of powdery organic fertilizer is relatively simple. The main production machines are the following five parts: organic fertilizer turner, forklift, ration feeder, pulverizer, and screening machine (drum screener machine or vibrating screener).

Equipment and equipment need to be connected by belt conveyor to form a complete organic fertilizer production line

1. A belt conveyor above the crusher is connected to the large pieces of raw materials that have been screened.

2. A belt conveyor above the screening machine connects the fermentation raw materials.

3. A belt conveyor below the sieving machine connects the sieved finished material, and sends the finished material to the processing site for weighing and packaging.

4. The warehouse needs a conveyor for loading.

The price of a set of organic fertilizer production equipment generally ranges from 200000 to 10 million yuan, and the specific price depends on factors such as the type, scale, technology, equipment quality, and brand of the fertilizer. At the same time, it is also necessary to consider transportation costs, installation costs, after-sales service costs, etc. Therefore, when purchasing organic fertilizer production equipment, one should choose appropriate equipment based on their own needs and budget, and comprehensively consider various factors to achieve the best economic and usage benefits.

1. The type of fertilizer is an important factor affecting the price of organic fertilizer production equipment.

Different types of fertilizers require different raw materials and production processes, so equipment prices may also vary. For example, the production equipment prices for organic fertilizers and bio organic fertilizers are generally higher because they require more raw materials and more complex production processes. The production equipment price of organic-inorganic compound fertilizer is relatively low because its production process is relatively simple, only requiring the mixing of organic and inorganic materials for granulation.

2. Scale is also one of the factors affecting the price of organic fertilizer production equipment.

Larger scale equipment requires larger venues, more workers, and more equipment, so prices are usually higher. Smaller devices are relatively cheaper, but their production is also relatively low.

3. The quality of technology and equipment is also a factor that affects prices.

Powder organic fertilizer processing equipment: flipping machine (used for composting process) – vertical crusher (crushing larger blocks in organic fertilizer) – screening machine (screening out non compliant organic fertilizers and returning them) – batching machine (adding other required nutrients to organic fertilizer in a certain proportion, which is an optional device) – horizontal mixer (mixing different materials evenly and using it in combination with batching machine) – single bucket packaging machine (used for quantitative packaging of finished organic fertilizer)

Granular organic fertilizer processing equipment: tipping machine – vertical crusher – drum screening machine (optional here) – batching machine and horizontal mixer (used in combination, belonging to optional equipment) – disc granulator – dryer and cooling machine – drum screening machine – round throwing machine (optional) – wrapping machine (optional) – single bucket packaging machine.

Different processes and equipment quality can lead to differences in production efficiency, product quality, and equipment lifespan. Therefore, equipment with higher prices usually adopts more advanced processes and high-quality materials to ensure production efficiency and product quality.

The organic fertilizer granulator is especially suitable for the granulation of light and fine powder materials, and more suitable for the granulation of npk fertilizer production line. The finer the basic particles of the fine powder material, the higher the sphericity of the particles and the better the spherical quality. In general, the particle size of the material before granulation should be less than 50. Typical application materials: suitable for organic compound fertilizers such as chicken manure, pig manure, cow manure, carbon black, clay, kaolin, carbon, phosphorus and potassium. The granulator developed and produced by our company is a granulator that has been carefully developed and repeatedly tested on the basis of the stirring tooth granulator and the rotary drum granulator. The machine produces bacteria at room temperature, and the structure design is reasonable. It can produce spherical granular products. The production granules have low water content, easy drying, high forming rate, good granule strength and beautiful appearance. It is the ideal bio-organic fertilizer, organic-inorganic fertilizer and organic fertilizer-inorganic compound fertilizer granulation equipment.

Granulator, flat die granulator, ring die granulator, etc. are welcome to consult.

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.

The organic fertilizer production line with an annual output of 20000 tons, taking poultry and livestock manure as an example, can process up to 80000 cubic meters of manure annually. Fertilizer made from cow manure and straw through high-temperature fermentation is very effective for soil improvement and promoting fertilizer absorption.

Process description of the production line for 20000 tons of cow manure straw powder organic fertilizer annually:

It mainly consists of equipment such as a stacker, crusher, mixer, granulator, dryer, cooling machine, screening machine, wrapping machine, automatic packaging machine, etc.

Working principle of an annual production line for 20000 tons of cow manure, straw, and powdered organic fertilizer:

1. Composting fermentation

The fermentation of bio organic raw materials plays a very important role in the entire organic fertilizer production process. Adequate fermentation is the foundation for producing high-quality organic fertilizers.

The organic fertilizer turner achieves complete fermentation composting and can achieve high stacking and fermentation, improving the speed of aerobic fermentation.

2. Crushing treatment

The semi wet material crusher is an efficient crusher with strong adaptability to organic raw materials with high water content. The semi wet material crusher is widely used in the production process of organic fertilizers, and has a good crushing effect on wet raw materials such as chicken manure and sludge. This crusher greatly shortens the production cycle of organic fertilizer and saves production costs.

3. Mixing treatment

After the raw materials are crushed, they are mixed with other auxiliary materials and stirred evenly before granulation. The dual axis mixer is mainly used for pre adding water and mixing powdered materials. Its spiral blades have multiple angles and can quickly and uniformly mix raw materials regardless of their shape, size, and density.

4. Screening

After cooling, there are still powdery substances in the finished product particles. All powdered materials and unqualified particles can be screened out through a drum screening machine. Then, it is transported by a belt conveyor to a mixer for mixing and granulation. Unqualified large particles need to be crushed before granulation. The semi-finished products are transported to the organic fertilizer coating machine.

5. Packaging

This is the final production process. The fully automatic quantitative packaging machine is an automated packaging machine designed and manufactured specifically for particles of different shapes. The weighing control system meets the requirements of dust and water prevention, and the material box can also be configured according to customer requirements. Suitable for batch packaging of bulk materials, it can automatically weigh, transport, and seal bags.

 Whether it is organic fertilizer production line, npk production line or bio-organic fertilizer production line, the basic organic fertilizer complete set of equipment includes fermentation equipment, crushing equipment, mixing equipment, granulation equipment, drying and cooling equipment, screening equipment, coating equipment and packaging equipment Wait. In order to improve the production quality of fertilizers, screening machines are required for classification. Rotary drum screening machin is a commonly used equipment in npk fertilizer production line and organic fertilizer production. It is mainly used for the separation of finished products and returned materials to achieve product classification and finished product classification. The combined screen is easy to maintain and replace, and has a simple structure. It is an ideal equipment for fertilizer production lines.

So what problems should be paid attention to in the work of rotary drum screening machine?

  1. When the screening machine runs smoothly, the trommel screen starts the feeding and discharging equipment for trial operation.

  2. Close the sealing isolation cover after normal discharge (during normal operation, the sealing isolation cover should always be in the closed position).

  3. Check the discharge particle size, whether there is leakage and dust.

  4. Run for half an hour, carefully check all parts, and deal with any problems in time.

  5. When working, the operation should be checked frequently. If abnormal operation or abnormal sound is found, it should be stopped in time to check, find out the reason and eliminate the fault.

  6. Installation of the screen body of the trommel screening machine. Determine the position of the discharge port according to the feeding port of the equipment, and determine the installation position of the screen body.

  7. Pre-embedded steel plate. Before installation, the steel plate should be embedded according to the requirements of the equipment installation drawing, and the upper plane of the embedded steel plate should be on the same plane. Pre-embedded steel plates required for installation. Foot bolts shall be prepared by the installation unit.

  8. Install the base bracket. Hoist both ends of the screen body on the base bracket, adjust the installation angle of the screen body to the design angle, and finally fix and weld.

1. It is necessary to determine the output of fertilizer production machine, such as the annual output of tens of thousands of tons, or the number of tons produced per hour, so as to determine the price.

2. It is necessary to determine the shape of the particles, whether they are powdery, columnar, oblate or standard round. Generally, the commonly used granulating equipment for organic fertilizer are: disc granulator, drum granulator, wet granulator, roller extrusion granulator, flat die granulator and ring die granulator. The selection of fertilizer granulator machine should be decided according to the local fertilizer market. The process of organic fertilizer equipment is different due to different particle shape, and the price of organic fertilizer equipment is also different.

3. It is necessary to determine the configuration level of fertilizer production machine. The configuration level is different, the price of organic fertilizer equipment is different, the number of labor is different, and the stable yield and high yield of organic fertilizer equipment are also different: generally, the equipment with high configuration should be added with automatic batching device, automatic packaging device, automatic quantitative feeding device, cyclone dust removal and ink dust removal.
4. It is necessary to determine the type of fertilizer production line, which is compound fertilizer organic fertilizer equipment or organic fertilizer organic fertilizer equipment. For the same yield, organic fertilizer and organic fertilizer equipment generally consider high water content, bacteria species are not resistant to high temperature, and the model is generally larger than that of compound fertilizer. There are four types of organic fertilizer, including pure organic fertilizer, organic-inorganic compound fertilizer, bio organic fertilizer and compound microbial fertilizer. There are different varieties of organic fertilizer and different equipment of organic fertilizer.

5. It is necessary to select the type of fermentor. The general fermentation forms are: stack fermentation, shallow tank fermentation, deep tank fermentation, tower fermentation and rotary cylinder fermentation. The fermentation methods are different, and the equipment for organic fertilizer fermentation is also different. Generally, the shallow tank tipper is most suitable for the principle of aerobic fermentation (advantages of shallow tank tipper: it is most in line with the principle of aerobic fermentation, not easy to form anaerobic, full and complete fermentation, and fast fermentation speed).

6. It is necessary to determine the level of environmental protection requirements. The places with low environmental protection requirements generally choose heavy-duty dust removal, and the investment of organic fertilizer equipment is less; for places with high environmental protection requirements, heavy-duty dust removal and ink dust removal are generally selected, which can meet the national air emission quality standards.
