Organic fertilizer stirring tooth granulator: This organic fertilizer granulator is widely used for the granulation of organic fertilizer. Due to its high granulation rate, stable operation, sturdy and durable equipment, and long service life, it is chosen as the ideal product by the majority of users. The internal rotary tooth granulator developed and produced by our unit has four specifications: Φ400, Φ600, Φ800, Φ1000, and can also develop and produce other specifications of stirring tooth granulators according to user requirements. The shell of the granulator is made of thickened seamless steel pipe, which is durable and never deformed. Coupled with a stable base design, it runs more smoothly.

The above is the difference between the several organic fertilizer granulators that I have explained to you. These organic fertilizer granulators are the more commonly used types of granulators. The above detailed explanation can help you according to your own situation. , And effectively help everyone to set up a suitable organic fertilizer production line. Welcome domestic and foreign fertilizer manufacturers to come to our website for consultation. https://www.fertilizerplantcost.com/

The new type organic fertilizer granulator is composed of many neatly arranged spiral-shaped stirring teeth in its internal structure. It is also called an internal rotating stirring-tooth granulator. It is one of the special equipment for organic fertilizer granulation. Many raw materials with large water content are granulated, so it is also called wet granulator, which is widely used in the granulation of organic fertilizer chemical raw materials. Due to the high rate of granulation, stable operation, the fertilizer granulator machine is durable and long service life.

The internal rotary tooth granulator developed and produced by FPC has more than Φ600, Φ800, Φ1000 specifications. Other specifications of stirring tooth granulator can also be developed and produced according to user requirements. The shell of the granulator is made of thick seamless steel pipe, which is strong and durable without deformation. Coupled with a stable base design, it runs more smoothly.

The working principle of the new organic fertilizer granulator: the new organic fertilizer granulator uses the high-speed rotating mechanical stirring force and the resulting aerodynamic force to continuously mix the fine powder in the machine, granulate, spheroidize, and compact And so on, so as to achieve the purpose of granulation.

The particle shape is spherical, the sphericity is ≥0.7, the particle size is generally between 0.3-3 mm, and the granulation rate is ≥90%. The particle diameter can be appropriately adjusted by the mixing amount of the material and the spindle speed. Generally, the lower the mixing amount, the rotation speed The higher the particle size, the smaller the particle size, and vice versa.

Application range: The new organic fertilizer granulation machine is especially suitable for the granulation of light and fine powder materials. The finer the basic particles of the fine powder material, the higher the sphericity of the particles, and the better the quality of the pellets. Typical application materials: chicken manure, pig manure, cow manure, charcoal, clay, kaolin, etc. It is specially used for granulation of urban domestic waste organic fermented fertilizer such as organic fertilizer raw materials, livestock and poultry manure, compost fertilizer, green manure, sea manure, cake fertilizer, grass charcoal, soil and miscellaneous fertilizer, three wastes, microorganisms, etc. The particles are spherulites.

The qualified granulation rate of the new organic fertilizer granulator is as high as 80-90% or more. It is suitable for a variety of different formulas. The compressive strength of organic fertilizer is higher than that of discs and drums, the large ball rate is less than 15%, and the uniformity of particle size. It can be adjusted by the stepless speed regulation function of this machine according to user requirements. This machine is more suitable for the direct granulation of organic fertilizer after fermentation, which saves the drying process and greatly reduces the manufacturing cost.

In recent years, the global NPK compound fertilizer market has seen tremendous growth, because people are increasingly aware of the urgency and necessity of balanced fertilization, and the development of NPK compound fertilizer production technology and formula has also played a certain role. In addition, NPK compound fertilizers usually have more premium space than single fertilizers. Therefore, many manufacturers put NPK compound fertilizers with more premium space than single fertilizers. Therefore, many manufacturers have included NPK compound fertilizers in their product portfolios.

The common granulation technology of compound fertilizer includes drum granulation, disc granulation, spray granulation, tower granulation and so on.

The high-tower nitrate rotating granulation method produces high-concentration nitro compound fertilizer. This technology sprays nicotine, phosphorus and potassium melts from the top of the tower, cools and agglomerates into granules during the landing process. In ammonium nitrate production enterprises, the use of high tower melting granulation method to produce compound fertilizer has the following advantages:

First, it can directly use concentrated ammonium nitrate solution and crushed solid ammonium nitrate for crushing to produce compound fertilizer. This operation simplifies the production process and ensures production safety.

Secondly, the melt rotating granulation process makes full use of the heat energy of the ammonium nitrate concentrate, the moisture content of the material is very low, and the drying process is not required, which greatly saves engineering consumption.

Drum granulator is the most widely used compound fertilizer processing equipment in compound fertilizer production. The formula limit is relatively small, and partial ammoniation can also be used. For most types of equipment, the production line can use 2-3 million units, the daily output is more than 280-400 tons, and the formula is more than 500 tons. Due to the small formula limit, high output, low investment, short construction period and other advantages, drum granulation technology is favored by many compound fertilizer manufacturers. And it is adopted by more and more compound fertilizer manufacturers. Using this method, we can use a drum granulator to complete the production process.

FPC independently develops and produces a complete set of fertilizer equipment such as fermentation equipment, drying equipment, granulation equipment, screening system, and batching system suitable for the production of organic fertilizer and bio-organic fertilizer.

In the organic fertilizer production industry, there are many types of equipment that can make organic fertilizer, and there are different supporting equipment according to different materials. We use poultry manure as raw material to analyze the two different organic fertilizer production of drum granulator and disc granulator.

The advantages and disadvantages of each granulator.

Disc granulation process characteristics:

The operation is intuitive, and the operation of the equipment can be grasped at any time. If an abnormality is found, the size of the particles can be adjusted in time. It is determined by the inclination and rotation speed of the disc, and the inclination and rotation speed of the disc can be adjusted. The control range of the particle size is wide, the adaptability is strong, and the ball formation rate is very high, which can reach 70% to 90%. The livestock manure organic fertilizer disc granulation process has short production process, simple structure, low investment and easy operation, which is more suitable for small and medium-sized enterprises.

Characteristics of drum granulation process:

Steam is introduced into the material layer in the drum to increase the temperature of the granulated material, dissolve the salt of the granulated material, and achieve a high liquid phase volume under low moisture content to meet the liquid phase volume required for material granulation. At the same time, the amount of evaporated water in the drying process is reduced. The inner wall of the drum is lined with a number of soft rubber plates or polypropylene plates, and there are vent holes at the corresponding positions on the cylinder. When the inner lining turns from the bottom to the upper with the cylinder at the same time, the inner lining sags due to its own weight, thereby causing adhesion The material on the inner lining falls due to gravity to achieve the function of automatically cleaning the conglomerate. During the operation, the operator can observe the ball formation of the material at any time, and take corresponding measures in time as needed to ensure the normal operation of the system.

There are quality pan granulator and rotary drum granulator in FPC. Welcome to our website to buy granulation machines.

Brief introduction of BB fertilizer production process:

1. The nitrogen, phosphorus, potassium, filler and other raw materials are transported to the relevant silos.
2. After weighing by each automatic metering device, it is sent to the premixer.
3. It is transferred to the horizontal BB fertilizer mixer (intermittent and continuous), the particles rotate through the horizontal BB fertilizer mixer to form an irregular curtain, and the evenly mixed particles incline slowly along the direction of the mixer. The discharge port rolls.

4. Transfer to the finished product bin, slide into the automatic packaging scale for weighing, packaging and warehousing.

The key to the production of BB fertilizer (mixed fertilizer) is as follows:

Follow the rules of chemical compatibility.

1. After mixing different base fertilizers, some reactions will reduce the critical relative humidity (CRH) and make the products absorb moisture and agglomerate. For example, urea and ammonium nitrate cannot be mixed directly. Because the CRH of the mixture is only 18.1%, most areas will absorb moisture, and some reactions will even cause nutrient loss, such as ammonium nitrogen (ammonium nitrate, ammonium sulfate, ammonium phosphate, etc.).

It should be mixed with alkali fertilizer with strong chemical activity (such as hot phosphorus fertilizer and potassium fertilizer) to avoid the loss of ammonium nitrogen (NH4-N). The addition of neutralizing agent (such as limestone, dolomite powder, etc.) in the mixed fertilizer also caused nitrogen loss.

2. Superphosphate and ammonium nitrate are mixed to form calcium nitrate [Ca (NO3) 2], which makes BB fertilizer (mixed fertilizer) viscous.

New Type Organic Fertilizer Production Line

3. When superphosphate is mixed with urea, crystal water will precipitate, but ammoniated superphosphate can be mixed with ammonium phosphate to obtain stable synthetic fertilizer. Ammonium superphosphate is mixed with ammonium nitrate or urea and chlorinated. The product made from potassium is more dry and has better fluidity than that made from granular calcium.

The dry liquid mixed fertilizer with nutrient concentration more than 50% can be obtained by using ammonium phosphate formula, and the qualified calcium phosphate is only 25% ～ 31%. Calcium is mixed with ammonium sulfate. It starts to heat up, then it settles, the water gets wet and forms a hard lump.

Strictly use of grain based fertilizer to reduce secondary separation

1. The strength of basic granular fertilizer should be guaranteed first. Its static strength should not be less than 2 × 106pa, can bear the extrusion, friction and other external forces in the production process without pulverization.

2. The grain size range of each base fertilizer is – 6 + 16 mesh, and the dosage of each material is between 25% and 45%. When the difference of the middle particle size of different components is less than 10%, the mixture will not be separated again. In addition, the turbulence and storage in the mixing process are reduced, and the soft mixing is realized, which can effectively reduce the segregation and secondary separation of the mixed products.

1. The moisture content and packaging temperature of fertilizer can be reduced by heating the dryer, cooling the dehumidifier and installing air conditioner, so as to make the moisture content of fertilizer lower than 0.6%, prolong the cooling time of fertilizer and reduce the packaging temperature.
2. Adding anti caking agent into the raw material to reduce the physical and chemical reaction between particles.
3. The uniformity of fertilizer particles can be further improved by improving the screening system.
4. Reduce the storage height and pressure of fertilizer.

How does the dealer do it?

1. Reduce the temperature and humidity of the warehouse, put the fertilizer warehouse in a cool and dry place, ensure no water leakage on the roof and no water accumulation on the ground, set fans in the warehouse, and cool and dehumidify if necessary.

New Type Organic Fertilizer Production Line

2. After a period of time, the fertilizer is often turned, especially the fertilizer with high nutrient content, which is easy to caking after a long time, so we should pay more attention to turning the fertilizer frequently.

3. The fertilizers easy to produce chemical reaction shall be stacked separately to prevent chemical reaction caking.
4. Reduce the height of compost with certain machines, reduce the pressure between particles.

5. Avoid blind ordering, reduce inventory pressure, prevent fertilizer accumulation time is too long caking.
6. Select products from regular manufacturers to prevent uneven granulation and agglomeration.

The reason of wear of the shell of double roller granulator
Zhengzhou SX professional technicians will analyze the reasons for the wear of the roller shell on the compound fertilizer production line on the roller granulator

1. raw material moisture, pH

The roller sleeve is made of stainless steel. It reacts strongly with the pH value of the substance. Improper moisture and pH of the material will cause acid-base corrosion on the roller surface and damage the roller surface.

2. material factors

Roller extruder mainly deals with dry powder materials. Due to the different hardness of the material, uneven forces will be produced during extrusion and ball formation, which will increase the wear of roller skin. From the perspective of material factors, the other factor is the uniformity of the raw material particle size. Different sizes of raw materials also lead to uneven force and wear of roller sleeve.

3. feed uniformity coefficient

The center of the axis of the parallel bar of the extruder is parallel to the surface of the roll skin. If the feed is seriously uneven, one end feeds more and the other end is fed less, it will cause uneven force at both ends of the roller, increase the friction between the roller and the material, and cause the roller to wear.

Measures to reduce the wear of the roller shell in the compound fertilizer production line of the roller extruder:
In the process of pelletizing of the roller extrusion granulator, the roller skin is inevitably worn.

However, if used properly, it can effectively reduce the wear of the roller skin, thus extending the service life of the roller skin. According to the above factors, the following aspects can reduce the wear of the granulator.

1. for materials with high moisture content and high pH value, inspection and adjustment shall be carried out.

2. roller material, it is very necessary to select the cylinder cover with good material, wear resistance, torsion resistance and corrosion resistance.

3. in order to supply working materials, the uniformity of feed must be controlled to avoid wear caused by uneven axial force of roller.
Effective maintenance is an important means to reduce wear.

In conclusion, the damage factors should be avoided in the daily operation of the compound fertilizer production line from to the roller extruder. Therefore, manual and conventional use can reduce the wear of the pelletizing roller of extruder, prolong the service life and reduce unnecessary waste.

Compound fertilizer is the main development direction of chemical industry. In the process of fertilizer production, different types and series of fertilizer equipment can be used to complete the production process of compound fertilizer.

Compound fertilizer gives full play to the role of original fertilizer and overcomes the shortcomings of some original fertilizers. First of all, compound fertilizer will develop to high concentration, which will increase the concentration of compound fertilizer and the content of effective nutrients in compound fertilizer.

Pan Granulation Compound Fertilizer Production Line

Compound fertilizer will develop in this direction. It refers to the differences of climate, soil, crops or characteristics in different regions, as well as the role of R & D and production of fertilizer to achieve optimal allocation of resources according to the actual needs of different regions.

Compound fertilizer equipment from sx FPL can produce fertilizer according to formula, avoiding the situation that the fertilizer raw materials used in different areas are the same but not suitable for the needs of different areas, resulting in waste of resources. There are certain requirements for the production formula of compound fertilizer equipment.

Double Rolloer Granulator for NPK Compound Fertilizer Plant

The quality of chemical fertilizer is the key factor affecting the growth of crops, and its performance is reliable. Professional fertilizer equipment can ensure the quality of compound fertilizer. Disc granulation production line for compound fertilizer production, drum granulation production line equipment can be called organic fertilizer.
