The process flow of the powdered organic fertilizer production line is as follows:

The production process of organic fertilizer powder is an important production technology, which can make organic fertilizers into powder form for easy storage, transportation, and application. This production process is generally divided into several processes, including raw material processing, proportioning, fermentation, dehydration, and powder making.

Pre processing; After the composting raw materials are transported to the yard, they are weighed by a scale and sent to a mixing and stirring device. They are mixed with organic wastewater from production and domestic use in the factory, and composite bacteria are added. The moisture and carbon nitrogen ratio of the composting fertilizer are roughly adjusted according to the raw material composition, and then mixed before entering the next process.

One fermentation; The mixed raw materials are fed into a fermentation tank using a loader and stacked into a fermentation pile. A fan is used to force ventilation from the bottom of the fermentation tank upwards for oxygen supply. At the same time, the pile is flipped for about 2 days and supplemented with water and nutrients. The fermentation temperature is controlled between 50 ℃ and 65 ℃ for aerobic fermentation. The fermentation cycle for this project is 8 days.

Fertilizer equipment four, automatic weighing and packaging machine.

The methods of livestock and poultry manure feed mainly include drying method, silage method and biological method. The main drying methods are: natural drying, high temperature drying and low temperature drying. Natural drying costs are low, but the drying time is too long and is easily affected by environmental factors such as weather; high temperature drying adopts high temperature quick drying.The drying machine is heated, the drying speed is fast, the sterilization effect is good, but the energy consumption is large;

The traditional granulation method is double roller granulator, including two kinds of roll granulation method and agglomeration method. Extrusion granulation is simple and practical. After fermented compost is adjusted to a moisture content of 20% to 30%, it can be directly entered into the granulator and extruded into cylindrical granules. For small plants with an annual output of less than 10,000 tons, disc granulation should be selected, and natural air drying can be used directly, without the need to configure drying equipment, equipment investment costs are low, and space is saved; organic fertilizer plants with an annual output of 10,000 tons should choose rotary drum granulator, the granulator is equipped with rotary drum drying equipment, which has large production capacity and good granulation effect.

Using the npk fertilizer production line, firstly, the bacteria and livestock and poultry manure are fully stirred by the method of stirring, so that the microbial bacteria can be integrated into the livestock and poultry manure. Type mixers, granulators, dryers, coolers, drum screening machines, coating machines, packaging equipment, belt conveyors and other equipment are then subjected to a series of harmless treatments such as rapid heating, fermentation, decomposing, and deodorization. manufactured organic fertilizer.

These devices can help you process and process raw materials, ultimately producing high-quality powdered organic fertilizers.

The process of an annual 50000 tons of powdered organic fertilizer production line

1、 Raw material preparation

The primary task in producing organic fertilizers is to prepare high-quality raw materials. Usually, the raw materials for organic fertilizers mainly include animal manure, crop straw, and food processing industry waste. These raw materials need to undergo pre-treatment such as collection, classification, crushing, and drying to ensure the smooth progress of subsequent processes.

2、 Mixing ingredients

Pre treated raw materials are mixed and batched in a certain proportion. The proportion of ingredients should be determined based on the type, purpose, and market demand of the fertilizer. Generally speaking, ingredients should contain an appropriate amount of nutrients such as nitrogen, phosphorus, potassium, as well as organic matter and microorganisms.

3、 Fermentation and maturation

The mixed ingredients enter the fermentation and maturation stage. This stage mainly decomposes the organic matter in the raw materials into stable organic matter and nutrients through the action of microorganisms. During the fermentation and maturation process, it is necessary to control the temperature, humidity, and ventilation conditions to ensure the activity of microorganisms and the fermentation effect.

4、 Crushing and screening

The materials that have undergone fermentation and maturation need to be crushed and screened. Crushing is the process of breaking large pieces of material into small particles for the convenience of subsequent processes. Screening is based on particle size classification to remove impurities and large blocks of material.

5、 Dry cooling

The material after crushing and screening enters the drying and cooling stage. This stage mainly aims to remove moisture from the material, reduce its moisture content, and facilitate storage and transportation. During the drying process, attention should be paid to controlling temperature and wind speed to prevent materials from overheating or clumping. Cooling is the rapid cooling of dried materials to prevent their spontaneous combustion.

6、 Crushing and sieving

The dried and cooled material needs to be crushed and sieved. Crushing is the process of further crushing materials into powder form for the convenience of users. Screening is the process of removing large blocks of material and impurities to ensure the quality of the product.

7、 Packaging and storage

After crushing and sieving, the organic fertilizer powder enters the packaging and storage stage. Packaging is generally bagged or loose, customized according to user needs. When storing, attention should be paid to moisture, sun protection, and fire prevention to ensure the quality and safety of the product.

Organic fertilizer processing plants are a promising investment choice that can generate considerable profits, and their market demand is constantly increasing in the current context of environmental protection and sustainable development.

Firstly, the profits of organic fertilizer processing plants mainly come from two aspects.

The first is the sales of organic fertilizers. With the increasing demand for green agriculture, the market potential of organic fertilizers is enormous. Organic fertilizer, as a pollution-free agricultural input that can improve crop quality and increase soil fertility, has a relatively high market price. Therefore, processed organic fertilizer can achieve good profits.

The second is the comprehensive utilization of waste. Organic fertilizer processing plants usually collect and treat some agricultural waste and household waste, converting them into organic fertilizers. This not only achieves resource recycling, but also reduces environmental pollution, and brings certain additional benefits to organic fertilizer processing plants.

As for investment, the investment scale and funding requirements of organic fertilizer processing plants will vary depending on specific scale and equipment requirements. Generally speaking, the investment amount of small and medium-sized organic fertilizer processing plants ranges from millions to tens of millions of yuan. The investment mainly includes land, factory buildings and equipment, raw material procurement, operating costs, and other aspects.

Regarding equipment matching, it usually includes crushers, mixers, deodorization equipment, fertilizer granulators, and so on. In addition, due to the production of a lot of wastewater and exhaust gas during the chicken manure processing, purification and discharge systems are also needed. When selecting equipment, it is necessary to consider your actual production needs and budget comprehensively. Meanwhile, in order to ensure the stability and efficiency of the production process, it is best to choose equipment suppliers with superior quality and good brand reputation.

According to the survey, the utilization rate of chemical fertilizers in my country is only 35% to 40%, and the rest is fixed by soil or leached by rainwater, causing environmental problems such as water pollution and eutrophication of lakes. Experts urgently call for reducing the use of chemical fertilizers, using more new biological fertilizers, and applying more organic fertilizers. The vast number of farmers also urgently need a new type of fertilizer to meet the needs of agricultural production.

The organic fertilizer npk fertilizer production line is mainly that the previously fermented organic fertilizer raw materials are crushed and then screened, and then the raw materials of the binder and other components to be compatible are measured, batched and mixed in an automatic batching mixing system according to the proportioning requirements ( Or after further drying to produce powdered organic fertilizer), the fully mixed material is uniformly and continuously fed into the granulator by the belt conveyor for granulation.

Choose a suitable organic fertilizer granulator according to specific process requirements. There are many types of granulators, such as roller extrusion granulator, disc granulator, rotary drum granulator, etc. For those with strict particle size control, it is recommended to use a roller extrusion granulator, and for those with general requirements for particle size and larger output, it is recommended to use a drum granulator for organic fertilizers.

Basically all granulation drying processes can be granulated with a double roller granulator. In particular, the particle size of the raw material powder is less than 2 mm, preferably less than 1 mm, which is very suitable for extrusion granulation. Crushed stone, powder, crystalline, granular and pellet raw materials are suitable. For potassium chloride, lower cost standard grades and by-products or products too fine to mix are suitable for extrusion. Although granular urea can be used, powdered or crystalline urea of ​​very small size is more suitable. In some cases, the particle size of the raw material varies so much that larger particles should be broken up first, resulting in a more even distribution of nutrients in the product.

More and more people want to become a part of the sheep manure organic fertilizer army, and how much does it cost to invest in a sheep manure organic fertilizer production line.

What does a sheep manure organic fertilizer production line include?

If you want to produce high standard sheep manure organic fertilizer, sheep manure organic fertilizer equipment is indispensable. A complete sheep manure organic fertilizer production line consists of a forklift feeder, a stacker, a crusher, a mixer, a batching scale, granulation equipment, a drying equipment, a buffer silo, a packaging machine, a dust collector, etc. Users can choose personalized equipment to complete the operation of the sheep manure organic fertilizer production line according to different production needs and material processing situations.

As for the process flow and supporting equipment, a typical organic fertilizer production line generally includes the following steps: raw material processing, fermentation, crushing, mixing, extrusion, drying, and packaging. The specific process flow can be adjusted according to your needs and site conditions.

How much does it cost to invest in a sheep manure organic fertilizer production line

The price of investing in a sheep manure organic fertilizer production line varies depending on the production situation. For example, different production capacities require different specifications and models of sheep manure organic fertilizer equipment, which naturally leads to differences in the price of a set of sheep manure organic fertilizer equipment. Therefore, there is no fixed price for a set of sheep manure organic fertilizer production line.

Investing in a sheep manure organic fertilizer production line starts at around 200000 yuan. Of course, the price will also be affected by factors such as market supply and demand and price fluctuations, among which equipment investment accounts for a relatively heavy proportion. Therefore, choosing an equipment manufacturer is crucial.

The main structure of the organic fertilizer drum granulator is an inclined rotary cylinder, which can be driven at a constant or variable speed. When the liquid content of the feed powder is appropriate, coagulation occurs and rolls in the rotary drum. The rotary drum has a certain slope, and the angle between its axis and the horizontal is below 10 °, which can assist the material in rolling along the length direction of the drum. A material blocking ring is often installed at the feeding end to prevent material backflow.

A stopper ring can also be installed at the discharge end to increase the thickness of the material layer and extend the retention time in the main drum. In other situations, a spiral discharge ring is often used to transport the boring material to the screen at the rear end of the drum. Sometimes a cylindrical sieve is integrated with a rotating drum to form a product discharge port.

The feed consists of fresh and recycled materials, and the feeding system can use belt conveyors, chute pipelines, or other similar equipment. Adhesive liquid can be injected before the solid material enters the rotary cylinder, or immediately after the solid enters the rotary cylinder.

Like a disc granulator, the surface structure of the inner surface of the drum plays a crucial role in determining whether the material can react well within the drum. The interior of a steel drum is usually made of thermally expanding metal. The function of various internal scrapers is to maintain a certain thickness of the material on the inner surface of the rotary drum, making the material layer uniform and facilitating normal rolling and flipping of the material inside the rotary drum. Rubber baffles, linings, and external vibrators are used to prevent accumulation during fertilizer granulation.

Before composting and fermentation in the livestock and poultry house, estimate the amount of manure produced by livestock and poultry in one day. Cover the manure with an appropriate amount of dry grass ash, furfural residue and other organic matter every day, and then inoculate the fermentation bacteria according to the proportion. Months or longer (time depends on the specific situation) to remove once, so that the fermentation process is completed in the barn. This not only eliminates the need for composting sites and reduces the amount of labor, but also can use biological heat production to increase the temperature of the house and save heating costs. It has strong practical value in the northern region in winter.

In the  organic fertilizer npk manufacturing process by using pig manure sewage and pig manure, the cross section of the manure storage tank is a regular octagonal structure, and a number of stirring guide bars are evenly distributed along the circumferential direction in the manure storage tank; The septic tank is arranged in a vertical direction, and the stirring guide strips are in a rhombus-shaped structure and are respectively located on the corners of the septic tank.

The overall structure design of the spherical organic fertilizer granulator is equipped with a corresponding rounding device on the granule press. This machine is the best for powder extrusion and granulation. It not only solves the difficult granulation of rotary drum granulator and double roller granulator structure, but also solves the granulation problem of poor granulation and molding, and also solves the process of throwing balls. At the same time, by improving the structure of the flat die, increasing the rotational speed of the flat die, adopting a threaded gap adjustment device for the flat die and the roller, and changing the traditional gasket method of adjusting the gap between the flat die and the roller to overcome the problems of high labor intensity and poor ball-forming effect. The existing granulator produces biological fertilizers with high temperature sterilization and poor granulation, and developed a new straw manure mixed organic fertilizer granulator with reasonable design, simple structure, easy operation, normal temperature preservation, and smooth granules.
