The NPK fertilizer production line is a set of process equipment specifically used for producing NPK compound fertilizers. Its main function is to mix various nutrients such as nitrogen (N), phosphorus (P), and potassium (K) in a certain ratio, and make granular compound fertilizers through specific processes. This production line is of great significance in modern agricultural production, as it can achieve customized production of fertilizers, meet the nutrient requirements of different crops at different growth stages, and improve crop yield and quality.

Firstly, the NPK fertilizer production line has achieved automation and intelligence in fertilizer production. By equipping automatic control systems and advanced production equipment, comprehensive monitoring and precise control of the production process can be achieved, ensuring that each batch of compound fertilizers produced has the same nutritional content and quality. This not only improves production efficiency, but also reduces manual errors, ensuring product consistency and stability.

Secondly, the NPK fertilizer production line can flexibly adjust the fertilizer formula and production process. According to the needs of different crops and the nutritional status of the soil, the ratio of N, P, K and other nutrients can be flexibly adjusted, and an appropriate amount of trace elements and bioactive substances can be added to produce customized fertilizer products that are suitable for specific needs. This flexibility enables the NPK fertilizer production line to meet different agricultural production modes and crop planting needs, providing more refined nutrient management solutions for agricultural production.

In addition, the NPK fertilizer production line also has the characteristics of environmental protection and energy conservation. By adopting closed-loop production processes and efficient equipment, the discharge of wastewater, exhaust gas, and solid waste can be minimized to the greatest extent, reducing environmental pollution and resource consumption. Meanwhile, optimized production processes and equipment design can also reduce energy consumption, improve the energy utilization efficiency of the production process, and meet the requirements of sustainable development.

In summary, the NPK fertilizer production line, as a key process equipment for fertilizer production, plays an important role in improving agricultural production efficiency, improving soil quality, and protecting the ecological environment. With the continuous development of agricultural production and technological progress, the NPK fertilizer production line will continue to play an important role, making greater contributions to agricultural modernization and sustainable development.

The npk production line equipment includes: crusher, feeder, horizontal mixer, double roller granulator, dryer, cooler, screening machine, weighing packaging machine and other equipment. However, whether it is an organic fertilizer production line, a bio-organic fertilizer production line, an npk manufacturing process, an npk blended fertilizer production line, or the production of commodity granular fertilizers, the dryer is indispensable. Today we will learn how to avoid oil leakage from the tumble dryer?

How to avoid oil leakage in organic fertilizer tumble dryer

(1) When the organic fertilizer drum dryer is running, if it is not cleaned in time, it is easy to cause some oil holes on the oil delivery pipe to be blocked by material slag, resulting in an increase in oil pressure in the oil pipe, an increase in the amount of oil sprayed from the oil ring, and it is easy to splash outside the equipment , causing oil leakage inside and outside the whole set of dryer. Therefore, in this case, the tumble dryer must be cleaned and cleaned in time to remove the oil spray holes.

(2) When injecting fuel, the fuel injection valve is increased, and the fuel injection volume is large. Generally, the oil will fall from the oil injection hole to some shafts inside the equipment. At the same time, the high-speed operation of the equipment will cause oil splashing, resulting in dry quality of the equipment and difficulty in operation. In response to this situation, technicians must fine-tune the oil injection link of the dryer to ensure that under the premise of normal oil injection and lubrication of the tumble dryer, no oil shortage and oil temperature will affect the equipment.

(3) When lubricating the dryer, because the oil falls off from the oil leakage ring, the entire equipment will leak oil. In order to eliminate this situation, the dryer sets a rubber plate between the oil ring and the oil hole to completely isolate the splash of the oil event.

(4) It is also possible to replace the parts of the entire tumble dryer, increase the overall area of the oil injection hole, and ensure that the lubrication of the oil shaft will not cause equipment blockage and oil leakage.

The disc granulator is suitable for granulating organic fertilizer, compound fertilizer, compound fertilizer, and organic-inorganic compound fertilizer: the disc granulator is face-to-face, easy to control, and adjustable flexibly. Install a water spraying device above the disc to spray it out in a mist shape. The material continuously flows into the rotating disc through a belt conveyor or other conveying equipment, is carried up as the disc rotates, and then falls down to the bottom along the bottom of the disc. At the same time, due to the addition of mist like water, the material gradually forms particles during the process of rotating and falling with the disc. As time goes on, the particles gradually increase. The disc granulator is designed with an angle adjustment mechanism, and users can determine the inclination angle of the disc according to the required particle size. Generally, the inclination angle of the disc can be adjusted between 35 ° -50 °, and particles that meet the specifications float above the inclined disc. As the disc rotates, the particles are thrown out along the tangent direction of the disc and flow into the belt conveyor for feeding. Pull the next step inside the mouth.

The disc granulator is powered by an electric motor, which drives the inclined disc to rotate. The internal scraper prevents the material from sticking to the bottom of the disc. When the material rotates above, it rolls down on its own, like a snowball rolling into particles. Suitable for non sticky powder materials.

The general organic fertilizer disc granulator is divided into two parts, with the fermentation part divided into three types of equipment: pre mixing equipment, tipping truck, and refining equipment; The organic fertilizer granulator equipment is divided into two mixers – crusher – granulator – dryer – cooler – screening machine – coating machine – automatic packaging machine, and the equipment is connected through a conveyor or elevator. Auxiliary equipment, baffle dust removal, cyclone dust removal, ink dust removal, induced draft fan and other equipment. In the past, we needed to adapt to the development of nature, which had little impact on our environment. However, with the continuous development of society, this has also undergone changes. To some extent, we have the ability to change nature, but we still passively adapt to long-term changes in climate and geology, and what we can remedy is limited remedial measures.

Cow and sheep manure is a good organic fertilizer raw material, and even if the raw material is good, good methods should be used. Currently, there are many production processes for organic fertilizers in China, and which one is more suitable? At the same time, it is also our goal that we have been pursuing. It is the responsibility of Organic Fertilizer Equipment Manufacturer to enable customers to use appropriate equipment.

In fact, no matter what method we use, the goal is to make the material into circular particles (market demand), and then reduce cost consumption when making circular particles.

According to our survey of fertilizer companies, over 90% of livestock and poultry manure producing organic fertilizers are using disc or drum granulation equipment, with a yield of 50-70%. The moisture content of the material is generally 50-60. This data is very reliable. I believe people who have made fertilizers can basically understand these data. We conducted a special investigation on cow and sheep manure (round particles). Many fertilizer companies use disc granulation or rotation.

These two types of equipment are mainly used for granulation of fertilizers and compound fertilizers, with the basic form of materials being the same. In the early stages, there were basically no professional organic fertilizer manufacturers in China, but many farmers composted themselves, so equipment for organic fertilizer production has gradually begun to be developed in recent years.

At present, the main raw materials for organic fertilizers in China are materials with high organic content such as animal manure, straw, and sugar residue. These raw materials belong to coarse fiber materials. If the decomposition time is not enough, there will be more coarse fibers, which will affect the overall granulation effect of the fertilizer. Disc granulation and drum granulation use the rotation of the equipment itself to bond materials together to form particles, but materials with more coarse fibers cannot form particles through rotation, even if the surface of the particles is rough.

Today, we will mainly discuss the granulation part; The organic fertilizer granulator is mainly designed to manufacture materials with a high amount of coarse fibers. After entering the granulator, the material first enters the feeding system. The feeding system evenly feeds the material into the granulation section. The granulation section is equipped with an alloy blade. The material is polished between the blade and the inner wall to form a master batch. The mother granules enter the plastic surgery area for further adjustment, forming complete granules. After matching the alloy blade, the fiber coarse material can be effectively degraded by 80%. So as to improve the granulation effect!

Common organic fertilizer granulators include: double roller granulator, rotary drum granulator, disc granulator, new organic fertilizer granulator, new two-in-one organic fertilizer granulator, flat die granulator machine, ring die granulator, let’s learn about the disc granulator today, what are the advantages of the disc granulator?

The disc granulator machine is an important part of the organic fertilizer or npk production line. Disc granulator is widely used to produce round granules of organic fertilizer and compound fertilizer. In this way, granular fertilizers are easy to transport and store. The fertilizer granulator has a wide range of applications.

1. The high-quality granulation rate adopts a full-arc disc angle, and the granulation rate can reach more than 93%. Then, it has three discharge ports, which is convenient for intermittent production, greatly reduces labor intensity and improves labor efficiency.

2. The manufacturing process of the disc granulator machine is advanced and the material is made of stainless steel plate, which makes the fertilizer equipment durable.

3. The disc granulator machine operating system is fully automatic. The automatic cleaning board above the sticky material improves the service life of the equipment and saves labor. The granulator requires only a control panel box to work. Therefore, it can save more labor for some small disc pelletizer iron ore pelletizing plants.

4. Our company is a professional manufacturer of organic fertilizer equipment. As a manufacturer of disc granulator with reasonable price, we belong to direct sales, not a third party.

Zhengzhou Huazhiqiang organic fertilizer equipment manufacturer is based on the principle of honest management, aggressive and pioneering, including organic fertilizer production line,npk production line, etc., perfect after-sales service and supporting facilities, is a main organic fertilizer granulator, organic fertilizer Turning machine, organic fertilizer pulverizer, organic fertilizer fermentation machine and other organic fertilizer equipment manufacturers for a complete set of organic fertilizer production lines.

The production of organic fertilizer mainly includes two stages: composting and composting, and composting, as the first step of the process, is even more important. If composting is not done well, even with the best materials, high-quality organic fertilizer cannot be produced.

Composting is the process of mixing poultry and livestock manure, straw, agricultural and forestry waste, and adding fermentation agents to make the materials undergo fermentation and maturation.

Poultry and livestock manure, straw and other materials contain harmful bacteria. After high-temperature fermentation, harmful bacteria can be killed and the occurrence of underlying diseases can be reduced. Grass seeds are often found in the feces of poultry and livestock, especially cattle and sheep. If applied directly, grass seeds can lead to overgrowth of weeds. After high-temperature fermentation, it can kill the rapeseed in the fertilizer. When unfermented materials are applied to the soil, they will automatically begin to ferment, and the high temperature generated by fermentation can cause root burning in crops. Completely decomposed materials will not increase in temperature and can be safely applied to the soil.

Why choose flipping equipment for high-yield compost fermentation?

For safety reasons, currently, aerobic fermentation is mainly used for composting. Aerobic fermentation, as the name suggests, requires oxygen and ventilation during the fermentation process. Moreover, during the fermentation process, the temperature of the pile will increase due to the action of high-temperature bacteria. In order to prevent the beneficial bacteria from evaporating at ultra-high temperatures, it is also necessary to periodically flip the materials.

To produce organic fertilizer on a large scale and continuously, at least 10 tons of new materials are added every day. To evenly flip 10 tons of materials, at least 4 workers need to work continuously for 2 hours. Pure manual flipping greatly increases labor costs.

Fortunately, with the development of the mechanical industry, flipping equipment has emerged. The flipping of 10 tons of material allows the machine to dry in just 2 minutes, greatly saving labor costs and time. And if the fermentation site is limited, the height of the compost can be increased to 2 meters, and using flipping equipment can still ensure that the material is fully flipped.

Organic fertilizer equipment usually uses the following steps for fertilizer processing when processing chicken manure:

Collecting and storing chicken manure:

Firstly, it is necessary to collect chicken manure in a centralized manner and store it in suitable containers or composting sites. This can be achieved through fecal cleaning equipment or manual cleaning within the farm.

Pre processing:

For raw chicken manure, preliminary treatment is usually required, such as removing impurities, foreign objects, large fecal blocks, etc. This can be pretreated through screening, deodorization, crushing, and other methods for better processing of organic fertilizers in the future.

Fermentation and composting:

Chicken manure is mainly processed through fermentation and composting in organic fertilizer processing. Mix the preprocessed chicken manure with other organic materials (such as straw, bran, etc.) in a certain proportion to form a compost pile, and promote the fermentation process by adding composting fermentation agents (such as bacterial strains, organic matter, etc.). During the fermentation process, attention should be paid to regulating the humidity, aeration, and temperature of the compost pile, promoting the decomposition and transformation of organic matter, and increasing the organic matter content.

Drum composting machine processing:

One of the commonly used equipment in organic fertilizer equipment is the organic fertilizer composter. This equipment can accelerate the decomposition and fermentation process of organic matter, and through mechanical stirring and ventilation systems, compost can ferment more evenly, improving the content of organic matter and the quality of fertilizer.

Drying and crushing:

After a certain period of fermentation and treatment, organic fertilizers need to be dried to reduce moisture content, improve fertilizer stability and storage. Drying is usually done by sun drying or mechanical drying. Subsequently, the dried organic fertilizer can be finely crushed by an organic fertilizer crusher to become granular or powdered fertilizer for easy storage and application.

Packaging and storage:

Finally, the processed organic fertilizer can be packaged and stored. Choose appropriate packaging methods, such as bagging, bulk, etc., to ensure that fertilizer quality is not affected by pollution and moisture. When storing, attention should be paid to ventilation, moisture prevention, and avoiding direct sunlight to maintain the quality and nutritional content of the fertilizer.

Through the above steps, organic fertilizer equipment can effectively process chicken manure, convert it into high-quality organic fertilizer, provide nutrient support for agricultural production, and achieve the resource utilization of organic waste, which meets the requirements of sustainable development.

Compound fertilizer is a fertilizer containing two or three nutrients of N and P; compound fertilizer is available in powder or granular form. It is usually used as top dressing, but also as base fertilizer and seed fertilizer. The complete npk production line produced by our company includes: belt scale, disc mixer, drum granulator, rotary drum granulator, drum cooler, drum coating machine, chain crusher, rotary screening machine, automatic packaging machine , belt conveyor and other accessories, the compound fertilizer production line is divided into 20,000 tons, 30,000 tons, and 50,000 tons according to production capacity. With years of experience in manufacturing compound fertilizer equipment, we can also assemble fertilizer production lines with greater output according to customer needs.

This compound fertilizer production line is mainly used for granulation of compound fertilizer particles using NPK, GSSP, SSP, granular potassium sulfate, sulfuric acid, ammonium nitrate, etc. as raw materials. Compound fertilizer equipment has the characteristics of stable operation. If we want to obtain npk granules, we know that we must use npk compound fertilizer granulation equipment. But do you know the working principle of the double roller granulator? The following is the process of npk fertilizer granulation.

• Firstly, with the help of the conveyor belt, the mixed material can be sent to the npk fertilizer double roller granulator, and the powdery material is input from the top of the machine.

•Then press the powdered NPK fertilizer between the two lower rollers for extrusion, and the rollers rotate relative to each other. Under strong extrusion pressure, cake-like materials can be obtained.

• Next, the cake-like material can be sent to the crushing chamber and crushed by the crushing shaft.

• Finally, the crushed material will be screened through the screen under the crushing chamber. Qualified particles are transported to the outside through the conveyor belt. The sieved powder is sent back to the raw material warehouse for secondary production.

The organic fertilizer production line for cow excrement and duck manure is a complete set of equipment that uses fresh cow excrement and duck manure as raw materials and undergoes a series of processing to produce natural organic manure.

The basic process flow of organic fertilizer fermentation with cow manure and duck manure:

1. 500kg cow manure+300kg duck manure+200kg bacterial residue+50g fermentation bacterial agent (cow manure and duck manure can replace other livestock and poultry manure)

2. Stacking of strip materials: The stacking of strip materials shall be carried out according to the above raw material ratio and requirements. The stacking length of the strip is unlimited, with a width of 2 meters and a height of about 1 meter. When stacking in strips, the materials should be evenly layered and stacked

3. Adding fermentation strains: The brand strains are multi strain composite products. The fermentation effect is better than that of ordinary strains. Expand the bacterial residue area of the strain in a 1:5 ratio (with the aim of diluting the strain and promoting uniform distribution. For example, mix 5kg of wheat bran or rice husk powder with 1kg of the strain), and determine the number of strains.

4. Sprinkle it on the surface of the pile. Stirring fermentation: Use a stirrer to stir the stack evenly. After the temperature reaches 55 ℃ or above, flip the pile every 1-2 days. After the fermentation temperature is above 55 ℃, stack the strips back in place after 10-15 days. The purpose of flipping the pile is to promote water evaporation, facilitate the entry of oxygen into the pile, and promote the rapid reproduction and fermentation of bacteria. Screening processing: After fermentation according to the above steps, it is screened to become pure powder organic fertilizer. At this point, the remaining large amount of organic fertilizer needs to be crushed before packaging.

Production equipment for organic fertilizer fermentation of powdered cow manure and duck manure: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)

Fertilizer granulator is a key agricultural machinery equipment that converts bulk fertilizer raw materials into granular fertilizers through a series of process steps for easy application and storage. In modern agricultural production, fertilizer granulators play an indispensable role, greatly improving the efficiency and quality of agricultural production.

Firstly, the fertilizer granulator achieves precise application of fertilizers. By compressing loose fertilizer raw materials into granules, uniform mixing and distribution of fertilizers can be achieved, ensuring that each piece of land can obtain sufficient nutrients. This precise application not only improves crop yield and quality, but also reduces fertilizer waste and lowers the cost of agricultural production.

Secondly, the fertilizer granulator improves the storage stability of fertilizers. Granular fertilizers are easier to store and transport than bulk fertilizers, and are less susceptible to moisture and oxygen, thereby extending the shelf life of fertilizers. This is crucial for agricultural production, especially in the case of seasonal fertilization and large-scale planting. Stable fertilizer storage can ensure that crops can obtain sufficient nutrients throughout the entire growing season.

In addition, fertilizer granulators can also improve the chemical properties of fertilizers. By adding specific additives during the manufacturing process, the hardness, dissolution rate, and nutrient release rate of fertilizer particles can be adjusted to better meet the needs of different types and growth stages of crops. This customized fertilizer can maximize the nutritional needs of crops and improve the ecological and economic benefits of agricultural production.

In summary, as a key tool in agricultural production, fertilizer granulators play an important role in improving agricultural production efficiency, improving soil quality, and protecting the ecological environment. With the continuous progress of technology and the increasing demand for agricultural production, fertilizer granulators will undoubtedly play a more important role in the future, providing strong support for the modernization process of agriculture.
