Time to use organic fertilizer

Most garden soils contain the most basic necessities. But it may not be enough. More is needed to fully develop.

When nutrition is needed for crop growth
Brass, potatoes and some other plants are more demanding – compost or dry manure is essential – poultry manure particles and buttons continuous planting season

Organic fertilizers are very useful because supplements see particles of poultry manure again
Lawns, shrubs, hedges, trees… Garden compost and manure is still a great supplier – find more lawn and shrub fertilizer here.

When growing on thin fertile soil

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 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.

How to appy bio fertilizer products?

The application of organic fertilizer can improve the soil structure, but its effective nutrient content is low and the fertilizer efficiency is slow. Biological fertilizer can enhance soil fertility, stress resistance and disease resistance, but the biological fertilizer itself does not contain nutrients.

According to the advantages and disadvantages of chemical fertilizer, traditional organic fertilizer and biological fertilizer. Zhengzhou SX chemical fertilizer plant has developed a new type of compound biological fertilizer, which has the functions of biological bacteria activating soil and transforming soil nutrients. We also designed the production method of biological fertilizer.

Benefits of applying biological fertilizer

Biological fertilizer has the characteristics of organic fertilization, soil improvement and rapid effect of inorganic nutrients, which can improve crop quality.

2. Biological fertilizer can increase the nutrient content of nitrogen, organic matter, soluble phosphorus and soluble potassium in soil, increase the number and quantity of beneficial microorganisms in soil, and enhance the function of disease resistance, drought resistance and metabolism of crops.

3. Biological fertilizer has a positive effect on increasing crop yield, improving crop quality and increasing agricultural economic income.

Production technology of pellet bio fertilizer

Due to the advantages of powder fertilizer, such as convenient agglomeration, uneven volume, unfavorable mechanized application, inconvenient transportation and storage, and serious use of biological fertilizer, granulation of biological fertilizer is an urgent need in actual production. The pan type fertilizer granulator is more suitable for the production of biological fertilizer.

Production of biological fertilizer with Pan fertilizer granulator

The effects of production formula, grinding fineness and water content of powdered fertilizer on granulation effect of compound biological fertilizer were studied. The fermented organic fertilizer was crushed and screened, and then mixed evenly with a certain proportion of inorganic fertilizer, and granulated by a pan fertilizer granulator. The pan type fertilizer granulator is equipped with spraying device, which can evenly add water to the material. In the process of biological fertilizer production, granulation is carried out according to the appropriate parameters, so as to improve the production efficiency.

Biological fertilizer granules are dried and screened to obtain the fertilizer we need.

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.

Urea fertilizer coating

With the continuous improvement of agricultural science and technology, the promotion of high-yield varieties, the improvement of land re cultivation index, the vigorous development of economic crops, flowers and urban greening. The phenomenon of crop growth and soil nutrient ecological balance is becoming more and more serious, and the phenomenon of crop sulfur deficiency is becoming more and more serious.

Sulfur urea has become a popular fertilizer product in the market. It is coated with sulfur and other trace elements on the outside of urea by coater and pulverizer, so that the nutrients of fertilizer are released slowly. It is different from the technology of rotary drum granulator of compound fertilizer.

Why should sulfur coated urea fertilizer be used

1. sulfur coated urea can improve the utilization of fertilizer, similar to the granular fertilizer made by disc granulator, and can control the release rate of fertilizer nutrients. Especially, the utilization rate of nitrogen fertilizer can be greatly improved, the efficiency of fertilizer can be nearly doubled, and the agricultural investment can be greatly reduced and the environment can be protected.
2. increase crop yield greatly. The application of different soil and crop has a good effect on the yield.
3. the sulfur coated urea fertilizer can improve the quality of the crop products.
4. fertilizer can be used as soil conditioner, and the effect of the treatment of saline alkali land is good.
5. reduce labor input.

The application of sulfur coated urea fertilizer at one time can meet the needs of different growth stages of crops. With the high cost and shortage of modern agricultural labor cost, the application of sulfur coated urea in some crops also shows its characteristics.

For example, planting sugarcane, because the cane grows for months, it is not easy to mechanized fertilization after the crown is closed. In the early stage of self-growth, single fertilization can meet the needs of crops and is welcomed by sugarcane farmers. Strawberries grown in plastic mulch are also easy to apply nitrogen, so 70 percent of California’s strawberry growers use sulfur coated waste.

We provide a complete production line of sulfur coated urea, as well as the chemical fertilizer production equipment such as disc granulator, drum granulator, double roller granulator, coating machine, packaging machine and so on.

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.

Production of NPK compound fertilizer by solid polymerization

Organic fertilizer fermentation

In the process of organic fertilizer manufacturing, fermentation products are often not handed in, which is usually caused by the viscosity of the object in the fermentation reactor. The trough turning machine used in organic fertilizer fermentation usually processes organic wastes such as sludge waste, slag cake, straw sawdust, livestock manure and sugar mill sludge.

Due to the different consistency of materials and different moisture content of materials, it is easy to see the difficulty of turntable treatment.

How to solve the problem of turning over materials of composting truck

The start-up temperature of the stacker should be better than 15 ° C (it can be operated all year round, not affected by seasons, ferment indoors or in Greenhouse in winter), and the fermentation temperature should be controlled below 70-75 ° C.

Turning machine for tank composting

1 kg starter can ferment about 10 tons of sludge and cow dung. According to the weight ratio, add about 30-50% cow dung, or straw powder, mushroom residue, peanut shell powder, or rice husk, sawdust and other organic materials to regulate ventilation.

If rice husk and sawdust were added, the fermentation time should be prolonged due to the high content of cellulose lignin.

Strain dilution: mixing and diluting 5-10 kg rice bran (or wheat bran, corn flour and other substitutes) per kilogram of appetizer, and then evenly sprinkle them into the material pile, the use effect will be better.

The moisture content of fermentation materials should be controlled between 60-65%. Moisture judgment: hold a piece of material tightly, the watermark of finger joint does not drop, and the ground is scattered properly. Fermentation with less water is slow, but fermentation with more

Construct fermentation reactor while spraying bacteria. The height and volume of the reactor should not be too short or too small. The fermentation reactor should be 1-1.3 meters high and 2-3 meters wide, with unlimited length.

The above is a brief description of the use of compost transfer machine in the fermentation process of organic fertilizer manufacturing process. We are a chemical fertilizer manufacturer, providing all kinds of composting turntable equipment.

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.

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 make different sizes of fertilizer granuels?

Disc granulator is one of the compound fertilizer production equipment. Its shape is mainly composed of disc, simple structure and intuitive granulation. In the production, by changing the parameters of the pelletizing plate, the production capacity of the equipment is improved, and the efficiency of the NPK fertilizer production line is improved.

Generally speaking, the diameter of Pan fertilizer granulator mainly depends on the output. Different fertilizer machine manufacturers will combine other equipment of NPK fertilizer production line according to their own conditions, such as annual production capacity. The annual production capacity of a 2-meter diameter disc granulator can reach more than 10000 tons, and the annual production capacity of a 2.2-meter diameter granulator can reach more than 15000 tons.

Therefore, the annual production capacity should be considered from the design point of view when selecting the disc diameter.

Pan fertilizer granulator

Once the diameter of the pan fertilizer granulator is determined, the plate height can also be basically determined. Generally speaking, the larger the diameter, the higher the disc height. However, the height of the disc also affects the granulation time. Due to the difference in friction coefficient between the raw material and the disc surface, the particles generated on the disc will have a grading effect.

Small particles will stop near the bottom of the disc, and large particles will be discharged from the edge. Therefore, the higher the edge of the disc, the longer the granulation time. If the disk is too high or too low, the ball forming time is short and the particle size is relatively small. Therefore, on the one hand, the plate height will affect the size of product particles discharged from the granulation plate, on the other hand, it will also affect the output.

Because if the material in the tray stagnation time is too long, the slower the product discharge speed, the larger the product particles, the larger the particles that do not meet the standard, and the lower the proportion of ball formation rate, it is very important to select the tray height reasonably.

Waste liquid of sodium glutamate organic-inorganic compound fertilizerproduction process?

The advantages of organic and inorganic fertilizer process for sodium glutamate wastewater are as follows

The role of organic fertilizer in improving soil structure, soil fertility, improving soil biological activity, promoting crop growth and improving crop quality has been gradually recognized. Making full use of the waste liquid of glutamic acid to produce organic and inorganic fertilizers can not only be converted into waste, but also help to prevent pollution and protect the ecological environment. The transformation of various wastes into treasures and comprehensive utilization of resources are the concrete embodiment of implementing the scientific outlook on development and realizing circular economy. The waste liquid from glutamic acid production is a high quality raw material for organic fertilizer processing.

Main components of glutamic acid wastewater

In the production of 1 ton sodium glutamate, about 20 tons of high concentration organic waste liquid should be discharged, including N13% ~ 16%, K2O2% ~ 5%, and most of the rest are organic substances, which contain 4.5% ~ 5.0% of various amino acids.

Processing technology of sodium glutamate wastewater from organic fertilizer production equipment

1. After precipitation and concentration, the waste liquid of sodium glutamate is put into the waste liquid storage tank, and the organic waste liquid is heated to the evaporation temperature by the heat provided by the steam boiler.
2. It is pressurized by the mud pump and sprayed on the material curtain of the granulator through the atomizing spray gun. At the same time, some qualified raw materials such as urea, monoamine phosphate, potassium chloride and fillers are transported to the relevant weighing equipment.
3. The material is delivered to the organic fertilizer granulator, in full contact with the organic droplets in the waste liquid storage tank, and saturated steam is introduced at the same time. Due to the friction caused by the rotation of the granulator, organic droplets form a rolling material bed. The extrusion pressure produced by rolling and the cohesive force provided by the drop of organic matter make the material aggregate into balls.
4. Transfer to the rotary drum dryer, heat exchange with the heat of the hot gas furnace; in order to prevent the organic matter content from decreasing due to high temperature carbonization, the temperature during drying must be controlled at 200 ~ 230 ° C.
5. Transfer to the thermal screening to sort the particles, and the small particles directly return to the organic fertilizer granulator, as the core, continue to participate in the agglomeration of particles into balls.
6. The screened semi-finished products are transported to the rotary chiller to cool the fertilizer through natural cold air or forced cold air. Large particles are crushed by a pulverizer and returned to the granulator to continue to participate in the formation of the ball.
7. Select qualified products and send them to chemical fertilizer coating machine for coating treatment.

If the granular organic fertilizer produced is not good, it will directly affect the texture and effect of organic fertilizer.

What details should be paid attention to when the organic fertilizer is produced by the organic fertilizer granulator?

1. The organic fertilizer granulator should be equipped with two powder bins for granulation, so that the granulator does not need to stop when changing the formula.

2. Before the organic fertilizer raw material enters the organic fertilizer granulator, an efficient iron removal device must be placed to protect the granulator from other impurities in the raw material.

3. The granulator of organic fertilizer should be placed on the cooler, and the crusher should be placed under the cooler

4. In order to make the organic fertilizer particles fall to the bottom of the box from a high place without damaging the bottom of the box, a vertical spiral slide should be installed in the box to slow down the impact.

5. The finished granular organic fertilizer should be packed and put into the finished product warehouse. Pay attention to the preservation of the environment to avoid the influence of organic fertilizer.
The above are some details that should be paid attention to during the operation of fertilizer granulator. These technologies not only save a small amount of power input, effectively reduce the cost, but also improve the efficiency of the task, improve the speed, and achieve satisfactory results.

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.

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.
