fertilizer granulator Jul 24, 2023

The characteristics of fermentation process can be summarized as follows:
Fertilizer production process attaches great importance to the pretreatment of organic raw materials before fermentation. The fermentation conditions of water, carbon nitrogen ratio and porosity were optimized after the raw materials and auxiliary materials were automatically weighed, tempered and mixed by the premixed conditioner;

The fermentation equipment adopts the original solar composting environment control technology. The fermentation workshop has excellent warming and heat preservation effects and control functions. The compost fermentation will not be affected by bad weather such as strong wind, rain and snow any more, which improves the fermentation environment in winter and realizes annual all-weather production;
The optimal combination of dynamic agitation and static aeration system of fermentation compost windrow turner. To realize the “four in one” balance of solar energy, biological energy, mechanical energy and wind energy to balance the overall fermentation temperature and material water evaporation, which is conducive to the complete maturity of composting materials and rapid reduction of water content.
The characteristics of granulation process can be summarized as follows:
The layout of granulation process adopts modular combination, one line multi-function, flexible production adjustment. According to the market demand, the product direction can be adjusted in time. It can produce not only the series of powdery organic fertilizer, but also the series of granular organic fertilizer and organic-inorganic compound fertilizer;
The pelletizing process adopts the extrusion pelletizing technology suitable for organic materials. The advantages of the organic fertilizer granulator are: it is suitable for both organic materials and organic-inorganic mixed materials. There is no need to add water and binder to granulate, and the raw materials do not need to be crushed too finely. It can save water and electricity, and the particle forming rate is more than 93%.
The organic fertilizer granulator has compact layout and smooth production connection. On the basis of speed control and uniform feeding, the one-stop operation of continuous grinding, continuous batching, continuous granulation, continuous drying and cooling, and continuous screening and packing is realized, which breaks through the “bottleneck” of traditional organic fertilizer production efficiency underground and reduces the system energy consumption.
The whole organic fertilizer production line has high degree of automation control, improved production environment, fewer workers and low labor intensity.

fertilizer granulator Jul 20, 2023

The organic fertilizer production line is the organic fertilizer granule line and the organic fertilizer powder line. We all know that if you want to make granular organic fertilizer, you must first make it into powder before granulation, so the powder line is an important part of the granular line. Now I will introduce the process of the organic fertilizer production line in detail with the granular organic fertilizer production line. According to the process layout, the process of granular organic fertilizer production line is as follows: Fermentation – crushing – mixing – granulation – drying – screening – coating – packaging. The technological process of powdery organic fertilizer includes the above four processes (fermentation, crushing, screening and packaging).

The preparation for the construction of organic fertilizer processing plant is as follows:
1) The construction of organic fertilizer production line should meet the requirements of environmental protection policies. For environmental protection, it is not only the wish of the people, but also the policy demand of agricultural and animal husbandry development for environmental protection.
2) The source of raw materials and the radius around the source of raw materials determine the location of the plant, site investment, transportation investment, etc.
3) The type of raw materials determines the detailed equipment used in each process stage, and affects the equipment investment price.
4) The production scale of a single organic fertilizer production line from 3000 tons per year to 250000 tons per year determines the capacity requirements of the equipment, thus affecting the price, etc.
5) The recycling of resources mainly relies on the recycling of agricultural non-point pollution wastes, such as fuel and electricity raw materials, and biogas residue produced as organic fertilizer raw materials.
6) The organic fertilizer production line can be used as feed for other purposes.
7) Construction site: it is necessary to determine the production site size and site size investment according to the planned production scale. 
The organic fertilizer production line mainly consists of five parts: raw material warehouse, belt conveyor, crushing, screening and packaging,; It is suitable for small and medium-sized organic fertilizer production process with compact layout, scientific and reasonable layout, advanced technology, energy saving and consumption reduction, no three emissions, stable operation, reliable operation and convenient maintenance, wide adaptability of raw materials, and suitable for various proportions of organic compound fertilizer, biological organic fertilizer, urban sludge, domestic waste organic fertilizer, etc. The designed annual production capacity is 1-100000 tons.

Fermenting Vermicompost to process fertilizer by Organic fertilizer production line

fertilizer granulator Jul 20, 2023

Vermicompost is called “the king of Manure” as a high-quality Manure. Vermicompost has the characteristics of good lasting fertility, aeration, drainage, water retention and comprehensive nutrients. Vermicompost contains not only nitrogen, phosphorus, zinc and other elements, but also iron, manganese, zinc, copper, magnesium and other trace elements and 18 kinds of amino acids. The content of organic matter and humus can reach about 30%. At the same time, Vermicompost contains about 100 million microbial beneficial bacteria per gram, more importantly, it contains antagonistic microorganisms and unknown plant growth factors. Through the action of probiotics, it can effectively inhibit the growth of pathogenic bacteria in soil and inhibit the occurrence of soil borne diseases. Therefore, it is a good investment project to use Organic fertilizer production line to produce Vermicompost Manure. It can be said to kill three birds with one stone.

Using livestock manure Organic fertilizer production line to process commercial Manure requires three steps: early fermentation, deep processing milling and deep processing granulation. The livestock manure Organic fertilizer production line is a series of production equipment that takes livestock manure as raw material, ferments and processes it through high-tech equipment, and produces Manure. It is equipped with fermentation tipping machine, Organic fertilizer grinder, drum screening machine, horizontal mixer, Organic fertilizer granulator, rotary dryer, cooler, screening machine, coating machine, packaging machine, conveyor and other equipment.

In order to make the Manure processed from Vermicompost more nutritious, it is better to mix coarse fodder in an appropriate proportion. And when processing Vermicompost, it is necessary to add sufficient water and add Fermentation starter in proportion. It is faster to ferment under sealed conditions, and it is better to dry the fermented Vermicompost after fermentation, so that the fermented earthworm dung has a longer shelf life.

1. If you want to process it into more nutritious Manure, you can add some coarse fodder in Vermicompost, such as: kukang, bean cake or rapeseed cake, which are suitable. Mix it evenly according to a certain proportion. It is appropriate that the proportion of Vermicompost should not exceed 50%, and other materials can be added appropriately.

2. During fermentation, keep the water content of Vermicompost mixed materials, and the proportion of water should preferably be about 60% of Vermicompost mixed materials. Because sufficient water is easy to ferment successfully, and the fermentation time can also be greatly reduced. The proportion of added fermentation bacteria and Vermicompost mixed materials can be 1:100.

3. If there are too many mixed materials for Vermicompost fermentation, it can be completed in the fermentation tank and must be sealed with plastic film. The fermentation time is normally about one week. The judgment method is that there is no odor and there is a bit of alcohol acid smell, which indicates that it has been successful. In order to extend the shelf life of Vermicompost fermentation, the fermented Vermicompost can be dried.

Organic fertilizer equipment in drying system after chicken manure fermentation

fertilizer granulator Jul 20, 2023

With the development of organic fertilizer machine, the chicken manure with high water content, strong viscosity and heavy pollution has been turned into waste, which has realized the comprehensive utilization of resources, effectively protected people’s production and living environment and brought greater economic benefits to users. So, in the chicken manure drying equipment, what are the basic organic fertilizer machines?
1. Hot blast stove. For drying equipment, hot blast furnace is an important equipment to provide heat source. The combustion of coal or gas resources in the hot blast stove is the main source of heat for the chicken manure dryer. According to the combustion value and combustion adequacy of the fuel, it is an important premise to ensure the sufficient heat provided to the inside of the dryer, which is to improve the drying efficiency and quality of chicken manure.
2. Belt conveyor. Before the drying of chicken manure, the fresh chicken manure with high humidity is first transported to the feed port by the belt conveyor, and then it enters the chicken manure dryer. During the operation of the fertilizer production process, the heat exchange between the fresh chicken manure and the hot air inside is sufficient. In the whole production line of chicken manure dryer, screw feeder is an important conveying equipment of chicken manure drying operation.

3. Chicken manure dryer. This is the main part of chicken manure drying, and also an important place for heat exchange of materials. After fresh chicken manure enters the drying drum, it is in constant contact with the hot air running in the downstream or upstream direction. Under the action of the lifting plate, the chicken manure is continuously turned up and scattered, increasing the heat exchange area, so as to better realize the evaporation of water in the material. After finishing the whole drying cycle, the chicken manure meeting certain drying requirements is discharged through the discharge port.
4. Dust remover. Any dryer equipment is equipped with corresponding dust removal device to remove dust pollution caused by material drying operation. Generally, bag type dust remover is used for chicken manure dryer to filter the waste gas mixed with dust produced in the drying process into the atmosphere.
It can be said that in the drying operation of chicken manure, the various organic fertilizer machines complement each other and cooperate with each other to realize the efficient drying of chicken manure. Therefore, in the process of using chicken manure dryer to dry chicken manure, we must not neglect the maintenance of any link.

fertilizer granulator Jul 20, 2023

Fertilizer is the food of plants.Fertilization is an important means to ensure the high and stable yield of crops in agricultural production.In many countries,the use of chemical fertilizer is very large.Although the yield of crops has been increased in a certain period of time and to a certain extent,the harm to the soil,water,source,agricultural  products and the environment is increasing day by day,such as:soil acidification,hardening,nutrition imbalance,groundwater pollution,heavy metal of agricultural products and nitrate content exceeding the standard,which leads to a variety of ecological environment pollution and human diseases.Due to the heavy and random application of chemical fertilizer,the lack of soil organic matter and the decline of soil fertility have become an important limiting factor for the sustainable development of agriculture and the stable and high yield of crops.The biofertilizer production line which it is to be equipped with different type organic fertilizer machine is also to be designed.

   The production process and technology of bio organic fertilizer:The technical content of bio organic fertilizer production is relatively high.In the fertilizer manufacturing process,it is to be equipped with different type and series organic fertilizer machine to finish the production process.In addition to adding biological agents to promote the maturity and decomposition of organic materials in the process of maturity,in order to achieve the purpose of directional maturity and deodorization,it is also necessary to add microorganisms with specific functions in the product to improve the effect of the product.At present,bio organic fertilizer is included in the category of microbial fertilizer in the world,and more strict management measure are implemented than organic fertilizer to promote the healthy development of organic fertilizer.
In the fertilizer manufacturing process,it is to be equipped with different type and series organic fertilizer machine.It is to be equipped with the fermentation compost turner machine to finish the fermenting process,and it is to be equipped with the fertilizer mixer machine,fertilizer crusher machine of different type to deal with the raw materials.There,if we produce the bio organic fertilizer into granulator,we can use the fertilizer granulation machine to finish the granulation process,the fertilizer granulator machine type to be designed different type,we can choose the suitable fertilizer granulator machine type to finish the granulation process.For example,in organic fertilizer production line,we can use the rotary drum granulator,disc granulator and new type organic fertilizer granulator machine to finish the production process.In npk fertilizer production process,we can use the double roller granulator machine to make the npk fertilizer granulator by using the extrusion method.And in the bio fertilizer production process,we can choose the flat die granulator machine to finish the production process to finish the granulation process.Different type fertilizer granulator machine can be used in different type fertilizer manufacturing process sometimes,and it has different type working principle.

What environmental protection methods do Organic fertilizer equipment manufacturers have?

fertilizer granulator Jul 20, 2023

Organic fertilizer production is an effective means of waste resource utilization, which can reduce the pollution of waste to the environment and is an environmental protection project. However, the management of some fertilizer production process manufacturers is not standardized. Many manufacturers produce in the open or build simple sheds, which will inevitably cause secondary pollution to the environment in the fertilizer production process, which violates the principle of environmental protection. Today, let’s talk about the pollution sources of organic fertilizer manufacturers and the corresponding treatment methods?
1. Waste gas and odor pollution
Most of the raw materials of organic fertilizer are wastes and perishable substances, which are easy to produce ammonia, hydrogen sulfide and other harmful gases during the storage and fermentation of organic fertilizer raw materials.
At present, there are many ways to eliminate odor and exhaust gas, such as water washing, combustion, adsorption, air dilution, masking, ozonation, plasma and biological deodorization. Biological deodorization is the most widely used method in the production of organic fertilizer manufacturers. This method uses the activities of microorganisms to decompose and transform the odor to achieve the purpose of deodorization. This method is simple and easy to operate. It is suggested that the organic fertilizer manufacturers should build closed raw material warehouse, fermentation workshop and secondary aging workshop when conditions permit, so as to reduce the leakage of odor and harmful gas in the transformation process.

2. Waste liquid pollution
Many raw materials of organic fertilizer contain a lot of water, such as pig manure, cow manure, chicken manure and other raw materials. In the process of raw material accumulation and fermentation, there will be waste liquid flowing out and infiltrating into the ground to pollute the underground water, so it is necessary to cement harden and impervious the ground of the fermentation workshop of the raw material warehouse during the construction of the plant.
3. Dust pollution
Dust pollution is the main pollution in the fertilizer production process, which needs to be treated carefully. There are many links of dust pollution.
(1) When the raw materials are unloaded into the warehouse and handled in different workshops with the carrier
(2) When the fermentation compost windrow turner dumps the raw materials
(3) When using the crusher to crush raw materials
(4) When the fertilizer particles are dried and cooled
Many organic fertilizer manufacturers will build dedusting rooms in their workshops, and use induced draft fans and dust collectors to solve dust problems. Common dedusting equipment include: cyclone deduster, pulse deduster, water curtain deduster, bag deduster, etc. It is explained here that although dust is the source of pollution, these dust are all from the raw materials of organic fertilizer. After collection, they can be added to the raw materials for fermentation and then continue to produce organic fertilizer.
4. Noise pollution
In addition to choosing the plant site far away from the residential area, low-noise organic fertilizer machine should be selected as far as possible; equipment maintenance should be strengthened to avoid high noise caused by abnormal operation of equipment; installation of equipment can increase damping measures; reasonable planning of plant site, use of buildings to reduce noise; construction of green belts, use of vegetation to absorb sound and other measures to reduce noise.

Equipment principle and performance advantages of self-propelled composting machines

fertilizer granulator Jul 20, 2023

The self-propelled composter is a Manure fermentation equipment developed based on dynamic composting. The earliest composting process is static composting, which is often converted into anaerobic fermentation due to insufficient oxygen supply, which will produce a large amount of hydrogen sulfide and other odor, and there is an explosion risk. Later, our company developed a new generation of Manure fermentation equipment, self-propelled fermentation composter, which can make full use of space, and the whole machine is solid; The vehicle body is flexible and can easily and conveniently lift the drum as a whole; Adopting advanced engineering machinery transmission technology to ensure no loss between energy conversions; Each component is connected to each other and can be adjusted separately; Under normal operation and attention to maintenance, using the machine is zero fault; Fully ferment the raw materials to quickly achieve the effect of no odor, no harmful bacteria such as Escherichia coli.

The self-propelled composting machine/self-propelled tipping machine has obvious advantages such as low investment, low energy consumption, fast composting, and high yield. The self-propelled Manure composter is an ideal equipment to use modern technology to transform agricultural wastes, stored feces and organic household garbage into high-quality biological Manure. Main features: It saves a lot of civil engineering and manpower and material engineering, making the scalability of fertilizer production more arbitrary and not limited by the site, allowing for multiple uses of one machine.

The self-propelled composter is the main machine of the complete set of equipment dedicated to the production of Manure. It adopts a four-wheel walking design, and can move forward, backward, and turn. It is operated by one person. When driving, the whole vehicle rides on the pre stacked strip Manure pile, and the rotating knife hung under the machine is used to remix, fluff, and move the raw materials of the fertilizer machine. After the vehicle passes, a new strip stack is formed, which can be operated either in the open field or in the workshop shed. A major technological breakthrough of this machine lies in the integration of the crushing function in the later stage of material fermentation. As the material gradually dehydrates, the knife equipped with a crushing device can effectively crush the plates formed during the fermentation process of the fertilizer. Not only does it save a crusher, but it also greatly improves the efficiency of crushing, reduces costs, and fundamentally solves the problem of limited production capacity of the crusher. Composting machines have significant effects compared to other types such as “tipping machines”, “mixers”, and “spiral stirring machines”. So one machine can be used for many purposes. It is not only a Manure dumper, but also a Manure grinder.

The Seven Steps of Processing Fertilizer on the Cow Manure Fertilizer Production Line

fertilizer granulator Jul 20, 2023

The cattle manure fertilizer production process, only 7 steps, makes the manure become organic fertilizer, and makes the cow manure greatly profitable.

1. Fermentation stage of cattle manure fertilizer production process:
Collect cow dung and urine, add auxiliary materials to make compost, and let it ferment. In the fermentation of seed, we use a dumper to fully ferment the cow dung, which can only be done in a timely and even way.
2. The composted materials, such as N, P, K and other inorganic fertilizers, and other additives are crushed, proportioned and mixed through the material crusher and horizontal mixer according to the proportion.
3. Granulation stage of cattle manure fertilizer production process:
A new type of organic fertilizer granulator is used to granulate materials.
4. Screening and recycling system of cattle manure fertilizer production process:
The size of the particles output from the pelletizing and forming system is different, so it needs to be screened and graded. The selected rotary screen machine requires small vibration, low noise, convenient screen changing and equipped with screen surface cleaning device.
5. Drying stage of cattle manure fertilizer production process:
Using the organic fertilizer dryer, the sieved particles can be further removed from the water to meet the standard requirements of the moisture content of organic fertilizer.
6. Cooling stage of cattle manure fertilizer production process:
Cooling the granular materials with a cooler is helpful for the storage and quality of the granules.
7. Packaging stage of cattle manure fertilizer production process:
The cooled granular materials are transported into the finished product warehouse by the bucket elevator. The granular materials can be weighed and packed quantitatively by automatic packing scale.
In the whole production process, the fermentation equipment of organic fertilizer is very important, and the quality of organic fertilizer also depends on the fermentation process. Therefore, the fermentation process of organic fertilizer is paid attention to by everyone. In the process of organic fertilizer fermentation, the heating time of organic fertilizer equipment refers to the early stage of the composting process. The temperature rise of compost gradually increased from room temperature to 45 ℃. The main microorganisms are thermophilic microorganisms, including bacteria, fungi and actinomycetes. The differentiation matrix was mainly carbohydrate and starch. The fruiting bodies of fungi can be found in time, and animals and protozoa participate in differentiation.
