Work in manure – continue to use organic fertilizer to make compost of better quality, and plant cloves and beans as green fertilizer digs. Check out the organic base fertilizer and decarbonized rock dust link here.
Some products cannot use organic fertilizer. You must consider the following:

Where does organic fertilizer come from? For example, are algae threatened by commercial development? Will mining calcified seaweed destroy marine life? Does your fish fat come from fish waste?

Do manufacturers use important resources or are they involved in pollution? For example, burning carbon from natural gas used to produce chemical nitrogen,
How can you do this? Transporting large amounts of fresh manure?
Is it excessive or wasteful? The use of urea has attracted many supporters, but they are all considered bad for organic gardening, are soil structural microorganisms destroyed?

Organic NPK Granules Production Technology

Roller granulator is a new dry granulation process for compound fertilizer production. Drying and normal temperature process are not used in production. After molding, the powder material with water content less than 15% is compressed into pieces. After comminution, granulation and screening, the flake material becomes the granular material meeting the requirements of use.
The roller granulator is produced by a process without drying and normal temperature, forming a primary. The equipment has the advantages of less investment, quick effect and good economic benefit.

How to pack organic fertilizer automatically?

With the further advancement of industrialization in China, robotization hardware has been applied increasingly more in the day by day fertilizer processing plants. Individuals have slowly moved from difficult work to mechanized creation. Programmed pressing machine is generally utilized in compost creation. It can not just improve the proficiency of natural manure creation line and compound compost creation line, yet additionally guarantee the nature of creation. All the more significantly, the programmed pressing machine further improves the exactness necessities in the manure creation measure.

PLC is a gadget uniquely intended for modern creation. In the event that the creation climate of programmed pressing machine is too unforgiving, electromagnetic impedance is exceptionally solid. Prior to guaranteeing the ordinary activity of programmed pressing machine in manure creation line, we should realize how to evade inappropriate establishment or use. So in the natural compost creation line and compound manure creation line, we should focus on the accompanying issues of programmed pressing machine.

1. Manure creation climate of programmed pressing machine. Completely programmed pressing machine is legitimately utilized in the mechanical field, and the ecological necessities are not high. Notwithstanding, if the surrounding temperature dips under 0℃ or above 50℃, the establishment of the programmed pressing machine will leave a ventilated spot. In the exceptional climate, we have to utilize the hood to secure.

2. To accomplish convective cooling beyond what many would consider possible, all segments of programmed pressing machine require to be introduced vertically. To evade outer electrical impedance, PLC must be far away from high-voltage power gracefully and gadgets, and can not be introduced in a control bureau with high-voltage gadgets. Every one of the three lines needs its own wiring.

Since the cycle of natural compost creation line and compound manure creation line are unique, and the utilization of programmed pressing machine is extraordinary, the creation line ought to be orchestrated by its own circumstance.

How to make fertilizer granules by extruding method?

Flat granulator is a kind of processing machinery in fertilizer plants. It is an extrusion fertilizer granulator, which is commonly used for fertilizer granulation.

The organic fertilizer production line of flat mold granulator has the characteristics of simple process, low equipment price and low power consumption, which is easy to use and maintain. The granulator can be used for granulation of organic fertilizer, compound fertilizer, feed and other materials. It has a wide range of material adaptability and many functions.

Application method of extruding fertilizer granulator flat die granulator

1. Before use, check whether the parts of the flat die granulator are tightened, whether the rotating parts are flexible, whether there is lubricant in the bearing, and whether the fertilizer granulator should be placed on a stable and stable ground. To check the power and voltage, the switch must be in the on position.

2. Check whether the clearance between the roller and the plate of the flat die granulator is kept at about 0.50 mm to prevent direct contact and abnormal wear. Select good mold aperture: select small mold when pressing small organic fertilizer; select large mold when pressing large organic fertilizer. During the operation of the organic fertilizer production line, attention should be paid to the site cleaning, and metal mixing into the powder and machine is strictly prohibited.

3. Start the flat mold granulator, check the granulation condition, check whether the surface of fertilizer particles is smooth and whether the temperature rise of particles is normal. By adjusting the bolts at both ends of the roller, the machine discharges normally.

How to make organic fertilizer from cocoa waste?

In the process of cocoa bean processing, there are a lot of wastes, such as bean shell, seed coat, seed embryo and so on. These wastes are treated and have certain use value. Cocoa waste is mainly bean shell, which contains more protein and fiber, and can be used as feed or organic fertilizer.
Bode shell is rich in nitrogen, phosphorus and potassium. Because the cocoa tree needs more potassium and the content of potassium carbonate in the bean shell is high, the bean shell is very suitable for the production of organic fertilizer raw materials.

Compost Making
Compost Making

Cocoa seed coating is also suitable for use as organic fertilizer. Fertilizer made from seed coating can reduce the viscosity of the soil and play the role of humus and humus. Seed coat is not easy to decompose. In the fermentation of organic fertilizer, seed coating needs to be pretreated, crushed into small pieces, and then composted for fermentation.
The production of organic fertilizer from cocoa waste can be divided into two stages: composting fermentation and organic fertilizer production equipment processing.

Fermentation composting of cocoa waste

The weight of bean shell accounts for a large part of the weight of cocoa fruit itself. After the cocoa beans are removed, the shells are usually discarded in situ. Pod shells are of great value. Therefore, the proximity principle should be adopted in the selection of organic fertilizer production site to facilitate the fermentation of raw materials.

Cocoa processing waste (bean shell, seed coat) is put into fermentation tank, and animal manure such as chicken manure, pig manure and cow manure are all added with regulating raw materials. After high temperature fermentation, harmful bacteria are killed.

Processing cocoa compost with organic fertilizer production equipment
Fermentation compost is produced into fertilizer products by the industrial processing of organic fertilizer production equipment. The basic fertilizer equipment for cocoa composting processing includes fertilizer crusher, mixer, organic fertilizer granulator, rotary dryer, rotary cooler and packaging machine. Different fertilizer products can be produced by different processing technologies.

Slow Release Fertilizer Production Process

Slow release controlled fertilizers release nutrients slowly in the soil to meet the nutrient requirements of the whole crop growth period. In the process of NPK fertilizer production, slow release and control of fertilizer are realized by granulation and coating.

Slow release fertilizer means that the release rate of available nutrients in plants is lower than that of fast fertilizer after fertilization in soil. Controlled release fertilizer refers to the regulation of nutrient release according to the set release mode and nutrient absorption law of crops. Release not only refers to the release period of fertilizer, but also refers to the release rate of nutrients in fertilizer, which conforms to the law of crop fertilizer demand.


Ideally, controlled release fertilizer can artificially control the supply and release rate of nutrients according to the nutrient requirements of different stages of crop growth. That is to say, nutrients can be released when crops need them and retained in the soil when they are not needed, so that a single application can meet all stages of crop growth.

NPK fertilizer production line processing slow release controlled fertilizer
NPK fertilizer production line can slow release and control fertilizer through fluidization treatment. The main production processes are: batch processing, mixing, granulation, drying, cooling, screening, coating, packaging. Fertilizer granulator is the key to slow release and control fertilizer processing. It determines the size, shape and hardness of fertilizer particles. Fertilizer granulator determines the appearance of the product, and the physical shape of the product also affects the fertilizer effect.

Rotary drum granulator is usually used for slow release and controlled fertilizer production for granulation. The roller granulator has the advantages of large production capacity, low production cost and spherical particles meet the production requirements of slow release fertilizer. The final stage of NPK fertilizer production and processing is coating. After particle coating, it becomes slow release fertilizer.

How to make npk fertilizer graules?

The physical and chemical properties, apparent structure and internal structure of products produced by different NPK compound fertilizer production processes are different. It leads to the difference of nutrient release, soil acidity and root zone nutrient change, which affects the relationship between nutrient release rate and soil nutrient supply and demand, and finally leads to crop growth. Differences in yield and fertilizer efficiency.

NPK Fertilizer Production Line Design Layout

Therefore, the difference of fertilizer efficiency between different processes of compound fertilizer is due to the differences of physical and chemical properties and structural characteristics of compound fertilizer itself, as well as the difference of manufacturing technology. In order to improve crop yield and fertilizer efficiency, NPK fertilizer production process must be improved.

NPK fertilizer production process solid aggregate method

In this method, single alkali fertilizers (such as urea, ammonium nitrate, ammonium chloride, ammonium sulfate, ammonium phosphate, potassium chloride and sulfuric acid) are used as raw materials. After grinding to a certain fineness, the raw materials are gathered and granulated in the drum of the rotary granulator by adding water and heating.

In the process of granulation, a small amount of phosphoric acid and ammonia can be added into the rotary drum granulator to improve the granulation conditions of NPK fertilizer production. It is one of the methods widely used in the world to obtain compound fertilizer products by drying, sieving and cooling granular materials. This method was used by the early United States, India, Japan, Thailand and other Southeast Asian countries.

How to make fertilizer granules by extrusion method?

Roller granulator specially designed for fertilizer manufacturing process. Fertilizer granulator is the main compound fertilizer granulation equipment, which has a broad market in domestic and international markets.

Processing principle of fertilizer roller extruder granulator

Roller extrusion granulator is a kind of drying granulation process which uses pressure to gather solid materials. The material is extruded by two counter rotating rollers, which are driven by an eccentric sleeve or hydraulic system. When extruding the solid material, the air between the powder particles is removed first, and the particles are rearranged to eliminate the gap between the materials.

When the brittle material is extruded, some particles are crushed and the fine powder fills the gap between the particles. In this case, if the newly formed free chemical bonds on the surface cannot be quickly saturated by the atoms or molecules in the surrounding atmosphere, the newly formed surfaces will contact each other and form strong recombination bonds.

When the material is extruded, the particles will deform or flow, resulting in a strong van der Waals attraction. In the extrusion process, the energy formed by pressure forms a hot spot at the contact point between the particles, which leads to the melting of the material, the temperature drop and the material cooling to form a fixed bridge. The thickness of large parts produced by extrusion is 5-20 mm, and the surface density is 1.5-3 times of feed. Large pieces, crushed and screened to obtain the required particles.

Fertilizer roller extruder granulator

The double roller of granulator is the key of fertilizer manufacturing process. The following is a brief description of how to adjust a volume.

1. Adjustment of roller clearance

First, loosen the bolts on the bearing housing, rotate the eccentric sleeve, and adjust it to the required thickness, so that the eccentric sleeve exerts radial force on the drive shaft. When adjusting the gap between the two rollers, the two rollers cannot collide. The minimum value should be maintained between 0.4 and 0.6 mm. Then tighten the bolts on the bearing pedestal.

2. Adjust the ball sleeve accordingly

First, loosen the bolts on the bearing seat, such as the axial dislocation of the ball sleeve, adjust the two eccentric sleeve cover bolts to make the shaft move left and right, so as to adjust the ball sleeve relatively. Tighten the bolts on the bearing housing. If the ball sleeve is not up to right, first release the bolt of the adjusting board, then adjust the top line of the concave part of the adjusting board, so that the reverse shaft can slightly turn to the spherical socket. Then tighten the bolts of the commissioning panel and loosen the top wire for use.

How to make bio fertilizer more efficient?

Biological fertilizer production equipment is mainly used for granulation processing of compound fertilizer, biological bacterial fertilizer, clay, crop straw, biogas residue, organic fertilizer of body acid, animal manure, rice husk, household garbage and various crude fibers.

Bio organic fertilizer can improve soil ecological environment and soil microbial community, and play a greater role in reducing crop diseases and insect pests. Biological fertilizer production equipment is widely used in agriculture.

In the production of biological fertilizer applicator, the flat mold granulator is commonly used as granulation equipment. The granulator has low material requirement and high granulation rate. Maintenance is an important method to avoid abnormality in the production of biological fertilizer device.

1. When storing the granulator, the dust should be removed and the chassis plane of the mobile device should be kept clean in time. In order to avoid the product can not be damaged by material, the movable bearing can not move smoothly on the chassis, which will lead to serious accidents.

2. Good lubricating oil is of great help to bearing life, so operators should ensure that the lubricating oil injected is as clean and well sealed as possible.
In the process of fertilizer granulator, if the load current of main motor is too small, the possible reasons for operating current less than 60% are as follows:

1. The feed rate is too low, and the granulator does not meet the pressure range required for granulation.
2. The content of urea nitrogen in raw materials is too high. The flat die extruder extrudes the material into a strip and cannot round the particles.
3. Due to the high moisture content of raw materials, the fertilizer granulator can not extrude the granules out of long strips and throw them into the round granules.

Solution: adjust raw material moisture or formula, adjust feed rate.
Flat die extruder granulator
If the current fluctuation of the pelletizing load is too large to exceed the rated current value during the operation of the flat die extruder, the possible reasons are as follows:

1. The impurity of material is too thick and the mould hole is blocked too much, which leads to the high pressure in the granulation area.
2. The content of crude fiber is too high. Water content is too low or uneven, extrusion pressure is too high, temperature is too high.
Solution: adjust the moisture or formula of raw materials, select raw materials, remove impurities, and then granulation, remove abrasive tools of the granulator, and clean the impurities inside.

How to make organic fertilizer?

With the popularization of organic fertilizer, the use of organic fertilizer production equipment is also greatly increased, which makes the demand of organic fertilizer equipment increase year by year.

Therefore, the standard operation of organic fertilizer equipment has become the focus of attention. The following is a brief introduction to the matters needing attention when the organic fertilizer manufacturing process is newly built and the project is put into use.

1. Before the start-up of organic fertilizer production equipment
Since all parts of the new equipment are not yet in operation, it is necessary to heat up the equipment for the first time, which usually takes 40-50 minutes. For a specific operation, first raise the temperature, pull the motor V-belt by hand until it is released, and then continuously pull the motor 8-10 times according to the normal operation option. Then keep heating for about 10 minutes.

2. Temperature control after start-up

Before starting the machine, we have made a preliminary temperature adjustment on the equipment. The material treatment of organic fertilizer equipment in the production process is determined by the characteristics of the material itself. Therefore, heating should be continued after start-up, because normal production requires continuous heat supplement; different temperatures are adjusted according to different properties of plastics.
Manufacturing technology of organic fertilizer

3. When the fertilizer manufacturing process works normally

During normal operation, the temperature of the drum granulator should be stable and should not be high or low. The temperature should be about 200 ° C near the nozzle until the machine head. At this temperature, most materials can be treated well. For the double roller granulator, granulation can be carried out at normal temperature, and the moisture content of materials should be paid attention to during the granulation process.

4. Close the organic fertilizer manufacturing process

First of all, cut off the power supply of the host, and the plug of the machine head (the part with wrench) must be removed. Preheat separately before next use. As the organic fertilizer production equipment is heavy machinery, the corresponding operation procedures and production projects must be strictly observed when operating the organic fertilizer granulation equipment to ensure the safety of production. When installing, pay attention to whether the host is vertical to the ground. After installation, first check whether the screw of the machine is loose and whether the air box of the main unit door is fixed. If there is any looseness, please strengthen it to avoid accidents.

How to produce npk fertilizer with double roller granulator

Double roller granulator is an important fertilizer granulator in NPK compound fertilizer industry. Using the extrusion principle, the fertilizer granules with a diameter of 3.5-10 mm are formed, and the granulation rate is higher than 85%. Double roller granulator is a common granulation method in NPK fertilizer production process. It does not dry at room temperature (moisture content is 2% – 5%).

Low cost and fast granulation speed bring good economic benefits for compound fertilizer investment.

Working principle of double roller granulator

Double roller fertilizer granulator machine is the representative of fertilizer granulator with extrusion mode. The dry material is compressed into a hard material. Dense blocks under pressure are extrusion processes. The blocks are then crushed, screened and pelletized, which is the granulation process. The function of extrusion is to squeeze the air between particles, so that the distance between particles is close enough to produce interaction. The hardness of particles produced by rolling is mainly attracted by intermolecular forces. Our double roller granulator is continuous extrusion of materials.

In NPK fertilizer production process, roller granulator has the following advantages compared with other fertilizer granulators:

Double roller granulator for NPK fertilizer production

1. There is no drying system in the fertilizer processing process of roller press granulator. The fertilizer can be granulated at room temperature with a moisture content of 2% – 5%. It forms once and costs less.
2. Rouble roller granulator has small power, reliable motor, no waste discharge, stable granulation and convenient maintenance.
3. Roller granulator has wide adaptability to raw materials. It can be used for granulation of compound fertilizer (including organic fertilizer, NPK fertilizer, biological fertilizer and magnetic fertilizer), mineral powder, chemical industry, feed and other raw materials.
4. This granulator has advanced structure, advanced technology and good economic benefits;
5. Popularize the series production of domestic fertilizer such as rare earth fertilizer, ammonium bicarbonate fertilizer and polysulfate fertilizer.

Plants for Biofertilizer Production

There are many kinds of organic fertilizer, and bio organic fertilizer is the leader. Biological fertilizer is a kind of fertilizer which combines microbial fertilizer and organic fertilizer.

Bio organic fertilizer products not only contain high organic matter, but also contain microorganisms with specific functions. The microorganisms contained in bio organic fertilizer products should have certain fertilizer functions, such as improving soil fertility, producing and assisting crops to absorb nutrients, activating insoluble compounds in soil for absorption and utilization of crops, or producing various active substances, disease resistant and disease resistant substances.

Biological planting can stimulate and regulate crop growth, reduce or reduce the occurrence of plant diseases and insect pests, and improve the quality of agricultural products.


Biological fertilizer plant mainly includes fertilizer granulator, crusher, mixer, drum machine, etc. Compared with common organic fertilizer, biological fertilizer production technology content is higher.

In addition to adding microbial agents to promote the maturity and decomposition of organic materials in the decomposition process, so as to achieve the purpose of directional decomposition and deodorization, microorganisms with specific functions need to be added in the production of microorganisms to improve the effect of products.

Fertilizer manufacturers will remind you that biological fertilizer is different from ordinary organic fertilizer in the production process. In the biological fertilizer plant, there is no difference from the ordinary organic fertilizer production equipment. The only difference is how to protect functional bacteria, improve the survival rate of bacteria in the production process, so as to maximize the efficiency of fertilizer.

Biological fertilizer plant

The following five points should be paid attention to when processing biological fertilizer production plant

(1) When processing and producing fertilizer, the drying temperature should not exceed 80 ° C, otherwise the number of active bacteria in biological fertilizer will be affected.
(2) When storing and transporting biological fattening, it is necessary to avoid damp or rain;
(3) In the process of biological fattening, direct sunlight should be avoided.
(4) The physical, chemical and biological factors of soil must be taken into account when using biological fertilizer.
(5) Biological fertilizer cannot be used together with pesticide and physiological acid fertilizer.

NPK fertilizer production caking problems

In NPK fertilizer production, sometimes the fertilizer coking occurs. Coking of chemical fertilizer usually occurs in the process of chemical fertilizer processing, storage, transportation and transportation. The main reasons are moisture absorption, surface dissolution, evaporation and recrystallization of fertilizer particles.

In this process, a crystal bridge is formed, and small particles become large particles and aggregates. The coking problem of NPK compound fertilizer is mainly related to material (raw material of NPK fertilizer production line), humidity, temperature, external pressure and storage time. So how to solve the problem of chemical fertilizer coking?

If you want to avoid scorching, you need to know the reasons for cutting gold to avoid loss. The following chemical fertilizer manufacturers specifically analyzed the causes of chemical fertilizer coking.

1. NPK compound fertilizer usually uses raw materials, such as ammonium salt, phosphate, trace element salt, potassium salt, etc. Most of these materials contain crystal water, which is easy to absorb water. For example, ammonium sulfate, phosphate and trace elements are easy to gather, but insoluble in water. Urea is easy to precipitate and aggregate when it encounters trace element salts.
2. NPK fertilizer production equipment processing is generally non closed production, in the production process, the higher the air humidity, the easier the fertilizer moisture absorption and addition. When the weather is dry or raw materials are dry, fertilizer is not easy to eat cake.
Double roller grain
3. The higher the working temperature of double roller pelletizer, the material is easy to dissolve. In general, the material dissolves in its own crystalline water and results in a complex. When the temperature of nitrogen rises, water evaporates and it is not easy to gather. The temperature is generally above 50 ℃. We usually need to heat to reach this temperature.
4. The greater the pressure of fertilization, the easier the crystal contact with the crystal, and the easier the firing group; the lower the applied pressure, the more difficult it is to get stuck.
5. After the double roller granulator is manufactured, the longer the fertilizer is placed, the easier the accumulation is, and the shorter the placing time is, the less difficult the cake is.

How to get compound fertilizer granules dried?

In the process of compound fertilizer production line, the material must be dried and cooled. At this point, a dryer, cooler and screening machine are required. Many customers are not familiar with chemical fertilizer processing technology. Here is how to dry and cool the materials in the  fertilizer production line.

Fertilizer Drying Machine for Chicken Manure
Fertilizer Drying Machine for Chicken Manure

The particles to be dried processed by NPK fertilizer granulator are transported to the feed port of the feeder through the belt conveyor, and the granular materials flow into the drying cylinder along the feed trough. The feeder is mounted outside the drying cylinder.

Driven by the deceleration drive system, the granular material moves backward with the rotation of the drying cylinder, and the heated hot air is blown into the feed end. It directly contacts the material of the drying cylinder, evaporates its water vapor and dries it.

In the drying process, according to the drying degree of the material, the deceleration drive system can adjust the speed through the frequency converter.

Dry and cold particles in compound fertilizer production line

The intermediate sensing draft hood draws steam from the drying cylinder. Then, as the drying material rotates, it enters the cooler again. Under the action of the middle induction draft hood, the natural wind enters the cooler from the unclosed end.

As the cooler rotates, the material is picked up and the material temperature is directly reduced to the natural temperature. After that, the granular material will enter the drum screen, and the unqualified material will be screened out from the drum screen, and the qualified material will go directly to the next packaging part.

Fertilizer Application Methods

Ammonium bicarbonate and diammonium phosphate are commonly used fertilizers in agriculture, which are processed by fertilizer production line. So, what is the key point of fertilization technology?

Ammonium bicarbonate

The nitrogen content of ammonium bicarbonate is about 17%, which is the lowest in solid nitrogen fertilizer. The moisture content of ammonium bicarbonate is generally 5% – 6%, and it is easy to deacidify and combine with acid. When the temperature is lower than 20 ° C, when the temperature is slightly higher or the moisture content in the product exceeds a certain standard, ammonium bicarbonate will decompose into ammonia and carbon dioxide, resulting in the loss of nitrogen fertilizer efficiency. It is a physiologically neutral available nitrogen fertilizer, which is suitable for various crops and soils, and can be used as basic fertilizer and top fertilizer. Therefore, it is also used as raw materials and other nutrients, and processed into other special fertilizers in batch through a pan granulator.

It can be used as fertilizer for ditch bottom. If it can be combined with the depth application of cultivated land, the effect will be better. However, it should be noted that the depth of application should be greater than 6cm (sandy soil can be deeper), and the soil should be covered immediately after application. Only in this way can nitrogen loss be reduced. When ammonium bicarbonate is used as a coat, the dry land can combine with the intermediate. The depth of application should be less than 2 inches. The soil should be covered immediately and watered in time. The paddy field should be kept about 1 inch shallow water layer, but not too shallow, otherwise it is easy to damage the roots. After application, plough in time to promote the absorption of fertilizer by soil.

When ammonium bicarbonate is used as a coat, it is important to remember not to apply it after rain or before dew dries. Ammonium bicarbonate, whether used as basic fertilizer or surface treatment, should not be sprayed on the soil surface to prevent nitrogen volatilization, nitrogen loss or damage to crops. At the same time, avoid high temperature season and high temperature period, and try to apply it in the season with temperature lower than 20 ° C.

Application of common fertilizer

Diammonium phosphate

Diammonium phosphate is a kind of fast fertilizer with high concentration, which is suitable for all kinds of crops and soil, especially for ammonium, phosphorus and other crops. It is suitable for basic fertilizer. If used as a top coat, it should be applied as early as possible before covering the soil with a depth of 10 cm. It should not be too close to the crops to avoid burning them. When used as seed fertilizer, it should not be in direct contact with the seed. Do not apply diammonium phosphate in water, otherwise most of its nitrogen will remain on the ground surface and should not be mixed with alkaline fertilizers (such as plant ash and lime) to prevent nitrogen volatilization and reduce the availability of phosphorus. We can also use NPK fertilizer granulator to further process high quality compound fertilizer.

How to get urea fertilizer coated?

Coated urea is a modified urea. So, why should urea be applied in the process of compound fertilizer production lines? There are two reasons:

1. Urea is a nitrogen fertilizer variety with the highest nitrogen content (n = 46%). In recent years, the actual effect of fertilization shows that urea is a kind of fertilizer with low utilization rate. Due to the large amount and low utilization rate of urea, the nitrogen loss caused by urea and the negative impact on the atmosphere and water environment are also large.

Drum coating machine

2. The reason for the low utilization rate of urea in agriculture is determined by the weak agricultural chemical properties of urea. The agrochemical properties of urea in soil are similar to that of ammonium bicarbonate. Soil cannot be absorbed and stored until it is absorbed and stored. At the same time of ammoniation, soil alkalization in micro area was also accompanied, which led to the increase of ammonia volatilization. The nitrogen content of urea is higher than that of ammonium bicarbonate, so the total volatile content of urea is higher than that of ammonium bicarbonate.

Material composition and processing technology of urea coating solution
The coating solution is a jelly composed of organic and inorganic substances. In addition to organic substances such as formic acid, a little salt forms of potassium (k), magnesium (mg), manganese (MN) and zinc (Zn) are added. Iron (FE), iron (b) and other nutrients. The coating solution is yellowish green with specific gravity of 1.17 ~ 1.18 and pH of 3 ~ 4.

Coating urea processing technology

Urea coating process is to use the coating solution and urea particle surface has a certain affinity, a small amount of solution evenly sprayed on the urea surface, and a small amount of penetration into the urea particles, the amount of coating solution per kg of urea is only 6-10 kg. With the help of hot drying and curing of urea, the coating solution can form a very thin film on the surface of urea particles after dry solid oxidation, which can be processed at one time.

We not only provide equipment related to urea coating production process, but also fertilizer granulator, NPK fertilizer granulator, extrusion granulator, rotary granulator, flat die granulator, organic fertilizer granulator, disc granulator, etc. Details go here.
