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?

Dry Granulation Fertilizer Production Technology

Non drying fertilizer granulation technology is mainly used for products with low water content. Generally, moisture content below 10% is a critical value. (some materials can reach 16%, for example, some contain only crystal water). Some organic fertilizer manufacturing processes have low water content, no need to dry, and save energy.

Dry granulation

The double roller granulator belongs to drying granulation equipment without drying process. It has high granulation density, good fertilizer efficiency and high organic content. The particles are flat and round, suitable for compound fertilizer.

Most of the particles produced by dry granulation are irregular particles (such as ordinary particle size potassium fertilizer), and their shape is similar to the shape of small gravel. The double roller granulator can produce all kinds of high, medium and low concentration NPK compound fertilizer and organic-inorganic compound fertilizer granulation, which meets the requirements of energy conservation and environmental protection.

Fertilizer granulation technology without drying extruder

The dry powder extruder consists of five parts: frame, head, pressure reducer, motor and crusher. It has the advantages of simple structure, high stability, convenient operation and maintenance, and strong adaptability of raw materials.

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.

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.

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 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.

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).

Why is organic fertilizer production so popular?

The content of soil organic matter is closely related to soil fertility. Although organic matter only accounts for a small part of the total soil, it plays an important role in maintaining soil fertility. The manufacturer of organic fertilizer production equipment introduced six functions of organic matter to maintain soil fertility.

Compost Made from Organic Waste
Compost Made from Organic Waste

1. Provide nutrition for plants

Soil organic matter contains a large number of plant nutrient elements, such as N, P, K, CA, Mg, Sn, Fe and other important elements, as well as some trace elements. Soil organic matter releases a large amount of nutrients through the mineralization process to provide nutrients for plant growth; humus synthesizes humus and preserves nutrients; humus releases nutrients again through mineralization process, so as to ensure the nutritional requirements of the whole plant growth process.

2. Promote plants to absorb other nutrients

In the process of decomposition and transformation of soil organic matter, the organic acid and thermal acid produced by the decomposition and transformation of soil organic matter have a certain solubility to the mineral part of the soil, which can promote the mineral differentiation and is conducive to the availability of some nutrients. Some metal ions combined with organic acids can be retained in soil solution without causing precipitation and affecting its availability.

3. Promote plant growth and development

Soil organic matter, especially polyphenol functional group, can enhance the plant respiration process, improve the permeability of cell membrane, promote the rapid introduction of nutrients into plants, and promote the growth of plant roots. Soil organic matter also contains vitamin B1, B2, propionic acid, nicotinic acid, hormones, IAA (+) – Non-Ethylene diacetate), antibiotics (streptomycin, penicillin), etc., which can promote plant growth and enhance disease resistance.

4. Improve soil physical properties

Organic matter has many functions in improving soil physical properties. The most important and direct function of improving soil structure is to improve soil structure, promote the formation of aggregate structure, increase soil looseness, and improve soil air and water permeability. Humus is the main cement of soil aggregate. Hu mu in the soil rarely exists in free state. Most humus and mineral soil particles combine with each other. Through the mechanism of functional group and hydrogen bond, the organic-inorganic complex is formed by wrapping the surface of mineral soil particles in the form of adhesive film. The distribution of agglomerates is reasonable, the stability of large, small holes and water is strong, and the structure is good. In arid areas, organic matter can reduce the expansion and contraction of soil by increasing soil viscosity, and prevent the emergence of large cracks when the soil is dry.

5. Provide energy for soil organisms

Without soil microbes, there would be no biochemical processes in the soil. The number, quantity and activity of soil microorganisms increased with the increase of organic matter content, and had a significant positive correlation. The mineralization rate of soil organic matter is low, and it will not stimulate microorganisms such as fresh plant residues rapidly, but provide energy for microorganisms continuously and stably. Therefore, the soil rich in organic matter has stable and long-term fertility, which is not easy to cause excessive plant growth and fertilization.

6. Activate phosphorus, potassium and other nutrients

Generally speaking, phosphorus in soil pool does not exist in the state of rapid action, but in the state of slow action and slow action, so the availability of phosphorus in soil is low; soil organic matter has the characteristics of reaction with insoluble phosphorus, which can improve the solubility of phosphorus, improve the availability of phosphorus in soil and the utilization rate of phosphorus fertilizer.

Organic matter plays an important role in soil. Organic matter is processed into balls by organic fertilizer granulator, which is widely used in farmland to maintain soil fertility. There has been a great increase in crop yield.

Why so many people prefer to make granular fertilizer

Benefits of organic fertilizer equipment processing granular fertilizer
Organic fertilizer has the functions of water storage, water saving, water reducing, evaporation reducing and drought reducing. It can reduce the application of chemical fertilizer, reduce the damage of saline alkali, regulate the soil, activate the activity of soil microorganisms, overcome soil hardening, and improve soil permeability.

Organic fertilizer mainly comes from crop straw, chicken manure, cow manure, pig manure and garden pruning waste. These raw materials are rich in a large number of beneficial substances, processed by organic fertilizer production equipment, and converted into treasures. On the market, organic fertilizers are usually made into solid particles and then sold.

What are the advantages of using organic fertilizer equipment to process granular fertilizer?

Advantages of organic fertilizer equipment in processing granular fertilizer

1. It is more convenient to apply granular fertilizer. Some organic fertilizers are light in proportion and easy to be dispersed by the wind when applied in the field, and become particles for easy application.

2. In the process of organic fertilizer granulating, some inorganic components can be added into the fertilizer to improve the fertilizer efficiency. If inorganic components are added to powdered organic fertilizer, it is easy to absorb water and aggregate. Granular fertilizer avoids this trouble.

3. Raw materials must be low in water to get powdery fertilizer, and compost must be crushed. The main limiting factor in the production of organic fertilizer is that the water can not be removed and needs to be dried. The granulation process of fertilizer can produce high temperature without drying. It just needs cooling, which is very convenient.

Organic fertilizer granule

For a long time, the unreasonable soil structure has been caused by the unreasonable agricultural production. Organic fertilizer equipment alleviates various problems in soil. Organic fertilizer is rich in organic matter and various nutrient elements, with stable fertilization effect and long time.

However, if we do not carry out scientific treatment, there are still some disadvantages, such as inconvenient transportation, unsanitary, low utilization rate of chemical fertilizer. The granulator of organic fertilizer solves the problem of using agricultural waste and improves the efficiency of agricultural production.

With the development of economy, the suitable raw materials of organic fertilizer are gradually expanded, and the demand for granular organic fertilizer equipment is increasing. We provide organic fertilizer granulator, pan fertilizer granulator and flat model granulator to solve different fertilizer granulation problems.
