Key points for process and equipment procurement of organic fertilizer production line

Now many people have a certain understanding of the organic fertilizer manufacturing process and equipment. For environmental reasons, the primary problem faced by breeding sites is how to deal with livestock manure. At this time, the organic fertilizer production line comes in handy.

Many people know that the production line of organic fertilizer is used to treat livestock manure into organic fertilizer. As an organic fertilizer equipment manufacturer, we also teach others how to make organic fertilizer. Now many countries and regions are also vigorously supporting the use of organic fertilizer, so many people want to buy a set of organic fertilizer production equipment to make fertilizer and make profits.


Organic fertilizer manufacturing process mainly includes equipment process

Composting machine — material grinder — blender — NPK fertilizer granulator — rotary dryer — rotary cooler — drum screening machine — coating machine — packaging machine.

Fermentation compost turning machine adopts advanced track, which can be lifted or not. The lifting type is mainly used in the working condition that the width of the tank is not more than 5 meters and the depth of the dump is not more than 1.3 meters. Pig manure composting fermentation dumper has a good limit switch, in the case of any abnormal situation, it can guarantee our safety in time, and also play a role in limiting the amount of materials.

Although the purchase of organic fertilizer production line mainly depends on the price, but the appearance is also very important. The appearance design should be able to meet consumers’ aesthetic point of view, so it can be comfortable to use. Now many manufacturers can customize colors, most of which can be customized according to users’ requirements. In addition, we should pay attention to the details of the equipment, whether the workmanship is fine, whether the welding trace is obvious, whether the screws are in place, and whether the appearance of the whole machine is smooth.

Method of fermenting organic fertilizer in sheep manure organic fertilizer production line

Technology of sheep manure fermenting organic fertilizer

The key processing step of organic fertilizer production line is fermentation process. Due to the different temperature in different places, the temperature in some areas is not high even throughout the year, which has a great impact on the fermentation time of organic fertilizer. The normal fermentation time is about 10 days. With the influence of different temperature in different areas, the whole fermentation cycle can be from 7 to 20 days.

The common method of sheep dung fermentation is trough fermentation, of course there are other methods. Trough fermentation is to use civil engineering to build a cement tank with a width of 3 meters and a length of 50 meters, and then install tracks on both sides of the wall, and the trough-type turning and throwing machine walks on the track to turn and throw the materials regularly. Put the sheep dung raw materials into the tank, generally the stack height is about 70 cm.

Then adjust the moisture of the raw materials. When the moisture is too high, add straw powder, rice husk and other organic plant residues. When the moisture is too small, pour into water or livestock and poultry urine. Adjust the moisture to 60%. Add organic fertilizer and start fermentation. Generally, 1kg of starter can ferment about 10t of raw materials.

In the fermentation process, trough compost turning machine is used to turn the pile once every two days, or turn and discard according to the temperature of the raw materials. Until the fermentation is complete.

Other processing processes of sheep manure after fermentation

In fact, after the sheep manure fermentation is completed, it will be regarded as organic fertilizer, but if we want to reach the standard of commercial organic fertilizer, we have to carry out the next step of processing. For organic fertilizer, the content of N, P and K should be 5% respectively, while the content of NPK in fermented organic fertilizer is not up to the standard of organic fertilizer, although it is rich in nutrients. It is necessary to use compost for granulation and add inorganic fertilizer in the process of granulation. Similarly, adding decomposed sheep manure compost in NPK fertilizer manufacturing process can greatly improve the fertilizer efficiency of finished products.

How to choose organic fertilizer granulators for pig manure fertilizers in different regions

When granulating pig manure fertilizers in organic fertilizer granulators in different regions, factors such as local climate conditions, soil types, crop planting characteristics, and environmental regulations should be considered. Here are some suggestions:

Climate conditions:

In areas with humid climate, dry granulation or semi dry granulation should be prioritized to reduce nutrient loss caused by high humidity and avoid compaction of soil by excessively wet fertilizers.

In arid areas, wet granulation of organic fertilizer granulators can help maintain the moisture content of fertilizers and prolong the release time of fertilizer efficiency. However, attention should be paid to controlling the moisture content reasonably to avoid affecting the storage and transportation of fertilizers due to excessive moisture.

Soil type:

For poorly drained clay soils, dry granulation methods that can provide faster fertilizer release should be selected to avoid soil salinization caused by excessive nutrient accumulation.

For well drained sandy soil, wet granulation can be used to fully utilize the nutrients in pig manure fertilizers while reducing nutrient loss.

Crop planting characteristics:

For vegetables and crops that require rapid growth, dry granulation should be chosen to meet their rapid nutrient absorption needs.

For long-term crops and fruit trees, wet granulation is more suitable because it can provide a long-lasting and stable supply of nutrients, which helps with the long-term growth of crops.

Environmental regulations:

In areas with strict restrictions on pollutant emissions, priority should be given to using environmentally friendly organic fertilizer granulation processes, such as combining biological fermentation technology with dry granulation, to reduce the generation of wastewater and waste gas.

For areas with specific environmental requirements, granulation processes that comply with local environmental standards should be adopted, and corresponding pollution control measures should be taken.

Resource recycling and utilization:

Encourage the use of pig manure resource utilization technology, such as anaerobic fermentation to produce biogas that can be used for energy recovery, reducing dependence on fossil fuels.

After appropriate pretreatment, pig manure can be used to produce organic fertilizers and achieve resource recycling.

Technical training and guidance:

Provide necessary technical support and training to help farmers master advanced pig manure fertilizer granulation technology and ensure its correct application in agricultural production.

Promote scientific fertilization methods, such as formula fertilization and precision fertilization, to improve the efficiency of pig manure fertilizer use and crop yield.

Through the above measures, it can be ensured that the granulation treatment of pig manure fertilizer is applied reasonably in different regions, which can effectively improve the utilization rate of pig manure fertilizer and protect the local environment.

Processing NPK fertilizer with rotary drum granulator to improve nutrient utilization efficiency

In the design of the internal structure of the rotary drum granulator, the function of various internal scrapers is to maintain a certain thickness of the material on the inner surface of the drum, make the material layer uniform, and facilitate the normal rolling and turning of the material in the drum. The steel drum is lined with thermally expandable metal. Rubber baffles and linings, as well as external shock absorbers, are used to prevent accumulation during the drum pelletizing process. The stable material volume and uniform liquid phase distribution in the rotary drum granulator are the key to producing qualified granules.

Clogging is one of the common failures of the grinder in the manufacturing of npk fertilizer. There may be problems with the machine design, but more are caused by improper use of the shredder.

(1) The feed rate is too fast and the load increases, causing the fertilizer crusher to block. During the feeding process of the organic fertilizer production line, you should always pay attention to the large deflection angle of the ammeter pointer. If it exceeds the rated current, it indicates that the motor is overloaded, and the motor will be burned out for a long time.

When this happens, you should immediately reduce or close the material door, or you can change the way of feeding, and control the amount of feed by increasing the feeder. There are two types of feeders: manual and automatic. The user should choose the appropriate feeder according to the actual situation.

Due to the high speed of the crusher, the large load, and the strong fluctuation of the load. Therefore, the current of the crusher is generally controlled at about 85% of the rated current.

(2) The outlet pipe is not smooth or the feeding is too fast, which will block the air outlet of the pulverizer. Improper matching with conveying equipment will cause the outlet pipe to be blocked after the air is weakened or no air. After the fault is found out, the feed port should be cleared first, the mismatched conveying equipment should be changed, and the feed volume should be adjusted to suit the processing of NPK fertilizer granulator, so as to make the equipment operate normally.

(3) Hammer fragments, aging, closed or broken screen holes, and too high water content of the crushed materials will block the crusher. The broken and severely aged hammers should be updated regularly, the crusher should be kept in good working condition, and the screen should be checked regularly. The moisture content of crushed materials should be less than 14%. This can not only improve the production efficiency, but also make the crusher not blocked, and enhance the reliability of the crusher.

Deodorization methods in the granulation process of organic fertilizer production line

Organic fertilizer production line is used to produce organic fertilizer, organic waste, sludge, straw, sawdust, food processing waste and other materials accumulated in a place for a long time, will produce a variety of odor. These wastes are processed by organic fertilizer manufacturing process, and become valuable organic fertilizer, contributing to the agricultural cause.

In the manufacturing of NPK fertilizer, fertilizer plants often carry out secondary granulation. The application of organic-inorganic compound fertilizer not only controls the balanced supply of nutrients, but also controls the stable release of nutrients. It plays a role of balanced fertilization in both horizontal and vertical directions of nutrients, and can improve the utilization rate of nutrients. Granular fertilizer treated by rotary granulator is better than inorganic fertilizer in comprehensive utilization of nutrients.

How does the organic fertilizer equipment deodorize these organic wastes? Here is a brief introduction.

There are many ways to eliminate odor, such as 1. Adsorption method; 2. Air dilution method; 3. Ozone oxidation method; 4. Masking method; 5. Chemical treatment method; 6. Water washing method; 7. Combustion method; and plasma and biological deodorization method.

The above methods are all one of the deodorization methods in the organic fertilizer manufacturing process. The methods used in each organic fertilizer production line are different, and each method has its own deodorization method and system. In the process of producing organic fertilizer, it is necessary to use compost turning machine for fermentation treatment, so that these materials can get rid of odor and harmful substances through deodorization system. Therefore, the deodorization system of organic fertilizer production line is an indispensable detail.

Advantages of composting and flipping machine for livestock and poultry manure fermentation

 The manure produced by farm-raised livestock and poultry can be made into organic fertilizer to bring certain additional economic value, and the compost turning machine can realize the efficient fermentation of manure and organic fertilizer.

So what benefits can be achieved by using livestock manure composting equipment. First of all, after a series of processes of the equipment, the feces are separated and processed, and finally organic fertilizer is formed.

Secondly, compost can be used for planting flowers, fruits and vegetables, crops, or directly applied to the field after fermentation, which helps to improve the soil environment and promote the development of ecological agriculture.

The farm will organically combine breeding and planting, and do three-dimensional breeding, recycling breeding and ecological breeding. Generally, 5 pigs (1 cow, 5 sheep and 50 chickens) can be consumed per mu of field. According to this plan, we can deal with the feces and solve the pollution problem.

In addition to the benefits achieved, our livestock and poultry manure composting and throwing equipment is manufactured by combining the requirements of harmlessness and resource utilization. It is suitable for organic fertilizer and NPK fertilizer manufacturing process. It has complete functions and good equipment quality.

How to choose the appropriate organic fertilizer granulator for different types of feces

When choosing a suitable organic fertilizer granulator, it should be determined based on the characteristics of different feces. Here are some common types of feces and corresponding recommendations for selecting organic fertilizer granulators:

Cow manure:

Cow manure has a moderate moisture content and high organic matter content, making it suitable for granulation treatment using a wet granulation machine.

The fiber content of cow manure is relatively high, and a wet organic fertilizer granulator with crushing function can be selected to improve the shaping effect of particles.

Chicken manure:

Chicken manure has a high moisture content and abundant organic matter, making it suitable for use with wet or semi dry granulators.

Due to the high viscosity of chicken manure, it may be necessary to add an appropriate amount of desiccant or conditioner to adjust its moisture and adhesion.

Pig manure:

Pig manure has a high moisture content and abundant organic matter, making it suitable for granulation treatment using a wet granulation machine.

Pig manure has strong adhesion and may require the addition of an appropriate amount of desiccant or conditioner to reduce its viscosity and facilitate granulation.

Sheep manure:

Sheep manure has a moderate moisture content and high organic matter content, making it suitable for granulation treatment using a wet granulation machine.

The fiber content of sheep manure is relatively low, and a wet granulation machine without crushing function can be chosen to reduce the damage to the fibers.

Rabbit feces:

Rabbit manure has a low moisture content and rich organic matter content, making it suitable for granulation treatment using a dry granulation machine.

The particle size of rabbit manure is relatively small, and a dry granulation machine with strong particle size adjustment function can be selected to achieve the desired particle size.

Other animal manure:

For other types of animal manure, such as pigeon manure, goose manure, etc., a suitable granulator should be selected based on their specific physical and chemical characteristics.

Generally speaking, these feces can also be processed using wet or dry granulation machines, but may require appropriate adjustments based on their characteristics.

When choosing an organic fertilizer granulator, in addition to considering the characteristics of the manure, factors such as production scale, investment budget, and energy consumption should also be taken into account. At the same time, in order to ensure the granulation effect and product quality, it is recommended to conduct sufficient testing and evaluation before purchasing.
