10. Exhaust gas is discharged after cleaning by dust collector, sedimentation chamber and water bath.

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.

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.

How to make organic fertilizer pellets by granulator?

Organic fertilizer granulator is an important mechanical equipment for organic fertilizer production. The function of organic fertilizer granulator is irreplaceable. What are the advantages of organic fertilizer granulator compared with other fertilizer granulators? The following is a detailed description of its features.

Organic fertilizer granulator

Instead of drying and crushing raw materials before granulation, spherical particles can be processed by direct ingredients, thus saving a lot of energy.
The characteristics of organic fertilizer granulator are used to produce pellets. The organic content can be as high as 100%. The granulation of organic matter can be completed.

Granulator uses organic particles under certain action, can be embedded in each other to grow, granulation does not need to add adhesive. Particles are solid and can be screened after granulation to reduce energy consumption without drying. Fermented organic matter can be processed in a fertilizer granulator. The moisture content of raw material is 20% – 40%.

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.

The following is a brief introduction of the new fertilizer granulator.

Compost Making
Compost Making

In the production process of granular biological fertilizer, fertilizer granulator is one of the most important equipment. The quality and output of granulator are closely related to the reasonable selection of granulator. Since fertilizer is sold in granules, it needs a good appearance for easy use; the yield of fertilizer is directly related to the production cost. From the perspective of enterprises themselves, they naturally hope to get the maximum benefit with the lowest cost.

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.

How to produce the best fertilizer with pan granulation

In the process of using organic fertilizer production equipment, if the safety in the operation process is strictly observed, the granulation rate will be effectively increased, the energy consumption will be reduced, and the service life of the equipment will be extended. Therefore, from the following aspects, we can adjust the pan granulator to make the fertilizer production reach the optimal state.

1. Strictly control the powder quality

(1) It is strictly forbidden to have iron block, stone larger than 10 mm and wood block larger than 10 mm in raw material discharge and supply of fertilizer production line. Rice bran and sand can not exceed the quality index, too much will cause the low output of the pan granulator.
(2) According to the formula of NK compound fertilizer, the quality of chemical fertilizer and other raw materials should be strictly controlled.

2. Transform the new blade in the CD

The blade of disc granulator is good, and the particle size is uniform and beautiful. The blade is divided into front blade and rear blade, and there is no gap between the two blades.

3. The main technical key of operating the disc granulator

(1) Do a good job in the technical training of personnel before operation, improve the technical quality and operation skills of the staff.
(2) The particle size of compound fertilizer is 70-90 mesh.

4. Select and adjust the nozzle of disc granulator

(1) The working mechanism of nozzle must be mastered when selecting nozzle

According to the hydrodynamics, it is proved that the bigger the pressure is, the smaller the through hole is and the larger the droplet diffusion surface is. At the same pressure, the spray hole is small, the droplet density is small, the spray hole is large, and the droplet density is high.

(2) How to choose the model and specification of nozzle

The smaller (or larger) the feed droplet and the smaller (or larger) the particle size, the lower (or higher) the yield of the fertilizer production line.
The denser (or thinner) the droplets, the higher (or lower) the output of the droplets they make (or smaller).

How to make organic fertilizer at large scale?

Bio organic fertilizer production line is the need of developing circular economy, building resource-saving and environment-friendly society, which conforms to the trend of agricultural development.

7. Drum projector

8. Granular fertilizer coating machine. The coating machine is composed of screw conveyor, mixing tank, oil pump and main engine, which can effectively prevent the coking of compound fertilizer. The main engine is made of polypropylene lining or acid resistant stainless steel.

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.

Humic Acid Fertilizer Production

Function and production equipment of low acid fertilizer
Blood acid fertilizer plays an important role in maintaining soil activity. In industry, manure, straw, mushroom residue, sawdust and other wastes are fermented by organic fertilizer production equipment, and then processed into organic fertilizer. This organic fertilizer product is rich in acid and blood.

1. Blood acid can improve nitrogen use efficiency

Nitrogen fertilizer is an indispensable fertilizer for plant growth, mainly urea and carbamine. When urea and ammonium bicarbonate are used in this field, they will soon disappear with the flow of air and water. Only 30% of nitrogen can be absorbed and utilized by crops. Aromatic nuclei, hydroxyl groups, carbon groups and other acidic functional groups in methanoic acid can react with nitrogen to form stable new ion groups. These compounds exist in the soil for a long time, and gradually decompose and release nitrogen, so that plants can slowly absorb.

2. It has synergistic effect on phosphate fertilizer

When the available phosphorus fertilizer is applied into the soil, the phosphorus element will be fixed by the metal ions in the soil, so that the available phosphorus can be converted into delayed phosphorus or ineffective phosphorus. The aromatic core, hydroxyl group, carbon group and other acidic functional groups in methanoic acid can react with phosphorus, making phosphorus become soluble phosphorus, increasing the activity of phosphorus element, which is easy to be absorbed by plants. According to statistics, the fertilizer efficiency of phosphate fertilizer can be increased by 5-10% after adding Heye acid fertilizer. Get more professional info on organic fertilizer production, welcome to https://organicfertilizerproductionline.com/

3. It has synergistic effect on potassium fertilizer

It can not only prevent the loss of potassium ion in sandy soil, but also prevent the immobilization of potassium in cohesive soil, and increase the utilization rate of potassium fertilizer by about 5%. In order to improve fertilizer efficiency, NPK fertilizer and blood acid organic matter are processed by fertilizer granulator in the process of organic fertilizer production.

4. It has the function of retaining water and fertilizing

Blood acids interact with calcium ions in soil to form flocculation and precipitation gel, combine soil particle cement, transform soil particles into small reservoirs and reservoirs, retain water and fertilizer, increase soil voids, and improve soil water and fertilizer retention capacity.

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.

8. Transfer to automatic packing scale for weighing, packaging and storage.
9. Drying, cooling and workshop dust are discharged after cyclone, labyrinth dust chamber and wet washing.

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.

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 make fertilizers good for plant grwoth?

Chemical fertilizer is one of the material bases of agricultural production. There are many kinds of fertilizers. Various fertilizers play different roles in the growth and development of crops.

Compound fertilizer

The chemical fertilizer containing two or more nutrients has the advantages of high nutrient content, small amount and good physical properties. It plays an important role in balancing fertilization, improving fertilizer utilization rate and promoting high and stable yield of crops. NPK fertilizer production line is industrialized to produce compound fertilizer granules suitable for different crops.

Humic acid fertilizer

The main raw materials of fertilizer are peat, lignite and weathered coal, which are treated by acid and alkali, and a small amount of inorganic fertilizer. It is rich in lactic acid and a certain amount of nutrients.

Effect: soil loosening, increasing soil temperature, improving soil onion exchange capacity and buffer capacity.

Compound microbial fertilizer

It refers to the combination of specific microorganisms and nutrients, which can provide, maintain or improve plant nutrition. SX organic fertilizer production machine can produce special commodity organic-inorganic compound fertilizer, improve the yield and quality of agricultural products.

Bio organic fertilizer

It refers to a kind of fertilizer which has the function of microbial fertilizer and organic fertilizer. It is mainly composed of specific functional microorganisms and organic materials mainly for automatic plant residue, harmless and decomposition treatment. Organic fertilizer granulator processes rotten compost into organic fertilizer granules.
influence:

  • Bio organic fertilizer 1. Improve the soil organic fertilizer;
  •  Provide all kinds of nutrients and stimulants for crops to promote and control the growth of crops;
  • Improving the ability of resistance to stress and disease resistance and reducing the disease index of continuous cropping crops can greatly alleviate the obstacles of continuous planting.

Bulk mixed fertilizer

A compound fertilizer by mixing several granular single fertilizer or compound fertilizer proportions. Comprehensive nutrition, high concentration, strong pertinence, BB fertilizer machine is simple. The formula of mixed fertilizer is flexible and can be changed according to different conditions of crop nutrition, soil fertility and yield level.

How to buy quality produced compound fertilizer products?

High quality compound fertilizer is produced by fertilizer granulator and other equipment. However, with the rise of social price, some bad businessmen use some inferior fertilizer as compound fertilizer to reduce the cost.

So in order to better let farmers choose high-quality fertilizer, let machine manufacturers introduce how to buy compound fertilizer.

1. Choose products produced by regular manufacturers
Due to the regular factory has a complete NPK fertilizer production line, fertilizer production technology is very advanced, the production of products and even granules, nutrition balance, stable quality.
