A Summary Of The Compound Fertilizer Production Process

When referencing compound fertilizer, this is merely a kind of fertilizer that has several components. When you have ever used NPK fertilizer, this is among the many types that are available. Of all the nutrients which can be put into these different fertilizers, nitrogen is often the most essential. Potassium and phosphorus also play an important role in producing most crops. However, there are plenty of others that may be useful, depending on the crops you will be growing within the time of the year you are doing the planting. Is a review of the way the compound fertilizer production process works if you are considering this as a project that for you to do all by yourself.

Compound Fertilizer Production Process

This all begins with storage bins which will have an abundance of powdery components. These are the basic nutrients that might be combined together, usually in the form of appellate, which will then decompose in the earth when they are spread to the surface. Compond fertilizer production plants are usually quite large. It will involve numerous components. This may incorporate a fertilizer crusher, packing machine, fertilizer mixer, and dryer that may make certain that excess moisture is taken off. Furthermore, a rotary screener is often employed to filter materials. By removing unwanted components, your fertilizer will be pure and may produce ideal results.

The Blending Method For Producing Granules

Blending all of these materials together may either be done manually, or it may involve a far more complex process. Many of the production systems today are controlled by computers. As a result the mixture in the different nutrients very exact. Whether this is a large-scale system, or one built to produce only some a great deal of fertilizer a year, you might need a space to set everything. It must also be arranged, detailed with conveyor belts, which can help in the production process of compound fertilizer. The blending method is the procedure for weighing the types of materials that you may be used to make the fertilizer pellets. These will be combined together, rotated, and ultimately processed into pellets which you can use or store.

Where Blending Occurs

This typically occurs inside of a rotating drum granulation machine. The rotating cylinder will almost certainly not simply mix the different components but will also be involved in the formation in the pellets. This could be a significant part of your compound fertilizer granulation line which may work nearly twenty-four hours a day. The blending process, given that the measurements have been done right, will result in a highly efficient fertilizer to your business. In some instances, it is possible to produce as much is 20 a great deal of this material every hour. This is perfect for large-scale production of compound fertilizer, or businesses that have multiple properties where various kinds of crops are grown.

Process of Processing Livestock Manure into Organic Fertilizer

The process of processing livestock manure into organic fertilizer:

The first step: fermentation

Collect livestock manure, mix it with hay and decaying silage, etc. to make compost, and let it ferment. In the fermentation process, the pile turning machine is used to fully ferment the livestock manure, which can only be achieved by turning the pile in time and evenly. Now some places are very dry and some places are very wet, which will affect the quality of fermentation.

Step 5: Drying

Use an organic fertilizer drying machine to further remove water from the sieved particles to meet the standard requirement of organic fertilizer moisture content.

Step 6: Cool down

Cooling the granular materials with a cooler helps the storage and quality of the granules.

Step 7: Packaging

The Processing Method of Dry Granular Fertilizer Is more Suitable than the Roller Extrusion Granulator

Non-drying granular fertilizers include urea, ammonium phosphate, compound fertilizer, potash fertilizer granules, etc., fertilizer granulation is one of the development trends of fertilizers. Compared with powdered fertilizers, granular fertilizers have good physical properties, no dust, long-term storage and no agglomeration, good fluidity, easy to spread fertilizer, and can realize aircraft sowing. At the same time, it can also play a slow-release effect and improve fertilizer performance. Utilization rate. There are three common methods for processing this kind of non-drying granular fertilizers: disc granulation, recrystallization and extrusion granulation. After long-term practical experience, we recommend using a pair-roll extrusion granulator to process non-drying granular fertilizers. , This kind of processing using a pair of roll extrusion granulator is more practical.

Dry powder-free processed granular fertilizers are mainly used for processing compound fertilizers and compound fertilizers. As the raw material of compound fertilizer, powdery is suitable, but as fertilizer for direct use, granular fertilizer is better than powdery products. The common processing methods of dry granular fertilizer include disc granulation, recrystallization and extrusion granulation. The three granulation methods have their own characteristics.

Comparison of three methods of non-drying granular fertilizer processing

Disc granulation. Disc granulation requires adding a binder to the powder, and at the same time it is obtained by drying and sieving. This method requires the addition of ineffective ingredients such as binder (usually clay) and water to reduce the nutrient content of the product.

Recrystallization method. The powder is dissolved in water, cooled, crystallized and separated into crystals and then crushed and sieved. The method has a complicated process, high cost, high consumption, and low market competitiveness.

Extrusion granulation method. A tablet press or an extrusion granulator is used to forcibly squeeze the powdered potassium fertilizer into tablets, which are then made into granules through processes such as slicing, granulating, and sieving. There are two types of extrusion granulation: roller type and wheel roller type. The roller type extrusion is firstly pressed into large pieces and then crushed into particles. In this way, the device has large capacity, high particle strength and low energy consumption. The wheel rolling type is to directly squeeze the material into a cylindrical strip in the laminating film, and then cut it into columnar particles. Most of the extrusion granulation methods currently used in China are wheel pulverization, and the production scale is small. A single double roller granulator machine can only reach 3~5t/h, and the granulation strength is limited, the mold is damaged, and the production is cylindrical granules. , Poor flow performance and other characteristics.

The double-roll extrusion granulator has obvious advantages in processing non-drying granular fertilizers

The roller squeezing granulator adopts rolling molding and crushing into granules. Extrusion granulation production has a wide range of raw material routes. At present, there are more than 20 kinds of materials that have been successfully used for extrusion granulation: ammonium nitrate, urea, ammonium chloride, calcium nitrate, potassium chloride, potassium sulfate, etc. In addition, the extrusion granulation process can flexibly realize the replacement of product formulas in a very short time, and a set of equipment can produce products with more than 30 formulas.

The design of the roller extrusion granulator is very reasonable, very practical, and low energy consumption. It can be continuously produced without drying at room temperature and once rolled and formed. The ball and socket on the roller can be manufactured according to the size and shape of the customer’s needs. At present, we There are spherical, pillow-shaped, semi-circular grain, rod, pill shape, walnut shape, oblate shape, and square shape. It is now used as a new energy-saving product in the compound fertilizer and organic fertilizer industry.

What Equipment Is Needed to Process Organic Fertilizer?

What equipment is needed to process organic fertilizer? Next, FPC will introduce the organic fertilizer equipment that needs to be used in conjunction with the production process of organic fertilizer.

moving type caomposting machine
  1. Fermentation of raw materials

The first step in the production of organic fertilizer is the fermentation of raw materials. There are three types of equipment used for raw material fermentation: manure fermentation tanks, self-propelled compost turners, and trough type compost turners. The purpose of using equipment is to save labor, speed up the fermentation of raw materials, make the fermentation of raw materials more uniform and thorough, and have reached the organic fertilizer content standard. The success or failure of organic fertilizer fermentation determines the quality of organic fertilizer, so the selection of fermentation equipment is very critical.

  1. Raw material crushing

In order to make the fermented organic fertilizer look even and fine, it is necessary to use a semi-wet material crusher to crush the raw materials. After crushing, high-quality powdered organic fertilizer can be obtained. The raw materials that are not thoroughly crushed need to be screened out by an organic fertilizer drum screening machine. Carry out secondary pulverization. If granular organic fertilizer is produced, the sieving step should be continued after the cooling process.

  1. Granulation

In order to be more convenient for transportation and storage, the powdered organic fertilizer needs to be granulated. The granulated organic fertilizer has high strength and density, which is more convenient for transportation and more convenient for later use. Generally, a new type of organic fertilizer stirring tooth granulator is used for granulation.

  1. Drying and cooling

The raw material during granulation still contains about 30% moisture, so the moisture in the granules should be removed in time after granulation to further improve the strength and prevent moldy or crushed during bagging and transportation. The granules need to enter immediately after being dried. The cooling system is convenient for further evaporation of water, and on the other hand, it is cooled and shaped. At this time, a rotary dryer and a cooler are needed.

  1. Particle screening

In the process of processing, there will be a small amount of oversized and oversized particles, which are screened out by the organic fertilizer drum screener. The oversized particles are returned to the granulator, and the oversized particles are returned to the pulverizer. Realize fully automated production.

The production of compound fertilizer by extrusion granulation process has the following advantages and disadvantages

  1. Extrusion granulation does not require heating and humidification of the materials, which saves investment and energy, and can also be adapted to the granulation of ingredients containing heat-sensitive materials, such as ammonium bicarbonate and certain organic fertilizers.
  2. No waste water or waste gas is discharged outside during the production process, and it will not pollute the environment.
  3. The extrusion granulation process is short, easy to operate, easy to realize automatic production control, and improve production efficiency.
  4. There are no special requirements on the properties and particle size distribution of the raw materials, so the source of raw materials is relatively wide.
  5. The production is more flexible, and the product plan can be changed at any time, which is conducive to the production of special fertilizers in small batches.
  6. The product has uniform particle size distribution, no segregation or agglomeration.
  7. The shape of extrusion granulation products is not as round as the particles produced by traditional methods such as drum granulation and slurry granulation; if chemical reactions occur between the ingredients in the product particles, the particles may collapse.

How to Extend the Service Life of Organic Fertilizer Granulator?

The most commonly used and most important equipment in a complete organic fertilizer production line is the organic fertilizer granulator. As we all know, the equipment has its own service life, but some people can use the same equipment for many years, but some People can’t use it for a long time, mainly because everyone has different operating methods. More importantly, they don’t pay attention to the maintenance of equipment. So how should the organic fertilizer granulator be maintained?

New deisgn organic fertilizer granulator machine
  • The operator should pay attention to regularly check the components that are easily worn out in the structure, and observe whether the degree of wear is not serious or very serious. If it belongs to the latter, it should be replaced immediately to prevent accidents caused by persistent use.
  • As for the plane of the bottom frame where the movable device is placed, pay attention to maintaining sanitation and remove dust and other materials in time to prevent the movable bearing from moving smoothly on the bottom frame when the pelletizer equipment encounters unbreakable materials, which may cause serious accidents.
rotary drum granulation machine for sale
  • During the operation of the organic fertilizer granulation equipment, it is found that, like some newly installed wheel tyres, it is very easy to loosen, so it needs to be checked frequently. In addition, once the bearing oil temperature is found to rise too fast, or there is an abnormal impact sound from the rotating gear, the power should be cut off immediately, and the reason should be checked and then solved in detail.

  • Good lubricating oil is very helpful to bearing life. Therefore, the operator must ensure that the injected lubricating oil is clean and has good sealing performance.

As long as you can always adhere to the above four points, you can greatly increase the service life of your pelletizing equipment, and the performance of the equipment can always be stable and efficient.

How Does the Organic Fertilizer Production Line Make Organic Fertilizer into Pellets?

With the development of environmental protection and organic agriculture, the use of organic wastes to produce organic fertilizers through biological fermentation has been rapidly developed, making the treatment of organic wastes harmless and resourceful. However, most of the organic fertilizer obtained by biological fermentation is coarse powder or irregular small lumps, which is very inconvenient to use, and is particularly unfavorable for large-area machine sowing. Making the coarse powder or irregular small pieces of organic fertilizer obtained by biological fermentation into spherical granular organic fertilizer is the key to solving the problem of large-scale popularization and use of organic fertilizer.

FPC will explain to you how the organic fertilizer production line makes organic fertilizer into pellets. The coarse powder or irregular small pieces of organic fertilizer after biological fermentation are characterized by high water content (30-40%) and looseness ( The bulk density is 0.3~0.4t/m3), and the fiber is much. The existing organic fertilizer in the form of coarse powder or irregular small pieces after biological fermentation is made into spherical granular organic fertilizer.

  • Some manufacturers use traditional discs or drums to granulate, and need to dry coarse powder or irregular small pieces of organic fertilizer (moisture content <15%) and crush them into very fine powder (greater than 100 mesh) . Then add the binder and inorganic fertilizer, and the addition amount of the binder and inorganic fertilizer in the organic fertilizer cannot be greater than 30%. Although this method can be made into spherical particles, the organic fertilizer in the processing process will be crushed by sufficient precipitation, then be granulated by adding water and then dried, repeated many times, so the processing cost is quite high. Moreover, due to the low density of organic fertilizer, the particle strength is low, which is not conducive to storage, transportation, and machine seeding.
disc granulator machine
  • There are also some manufacturers who first dry coarse powder or irregular small pieces of organic fertilizer until the moisture content is only 20-25%. Then, a flat die extrusion granulator or a pair-roll extrusion granulator is used to squeeze the dried organic fertilizer into columnar or oblate spherical particles. Although this method is more convenient to use, the fluidity is still not good, it is not suitable for machine broadcast, and the appearance is poor and the appearance is not good.
ShunXin roller pressing granulating equipment
  • Some manufacturers first use flat die extrusion granulatorto squeeze the coarse powder or irregular small pieces of organic fertilizer into short columnar particles (due to high water content and high fiber content, columnar particles also have a certain degree of plasticity). Then, it is polished to form spherical particles, and then the spherical particles are dried, cooled and sieved to obtain qualified particles. In this method, the raw materials do not need to be processed, the moisture sequence is reduced in steps, and the production cost is greatly reduced. However, this method also has some fatal weaknesses, that is, organic fertilizer is easy to arch, easy to block and easy to bond equipment, and at the same time, the output is small and the power consumption of the extrusion process is high.
Flat die granulator

Therefore, in summary, the organic fertilizer industry urgently needs to introduce a large-yield, low-energy compression granulating equipment to overcome the easy arching, easy blocking, easy bonding equipment, and small output of the traditional granulator. And the shortcomings of high power consumption in the extrusion process.

What Is the Difference Between Dry Granulation and Wet Granulation?

We often receive calls from many customers to inquire about matters related to the organic fertilizer granulator, and it is difficult for many customers to distinguish what kind of granulation method they need. The difference of the granulation method is to choose the corresponding suitable granulation method according to the use requirements of the material. It is mainly divided into two categories: dry method and wet method:

ShunXin roller pressing granulating equipment

Dry granulation

Mainly refers to products with relatively low moisture content. Generally, moisture content below 10% is a zero boundary value. (There are also very few materials that can reach 16%, such as some materials that only contain crystal water.) Dry granulation produces mostly irregular particles (such as common granular potash fertilizer) or, more generally speaking, like small gravel The sub-shapes are similar. With the current domestic industrial upgrading and environmental protection requirements becoming more and more stringent, many chemical and building materials powders need to be made into particles.

Disk Pelletizer for Poultry Manure Granulation

Wet granulation

There are also many equipment and methods in wet granulation for materials whose main indicator moisture is above 20%. Such as: plate granulation, roller granulation, screw granulation. The granulation methods used many years ago have been continued. After increasing the use environment and processing requirements of different materials, the continuous improvement has also made considerable progress. For example, the relatively popular organic fertilizer granulation in recent years, the particle size of these particles is between 1mm-6mm, and the above methods are used.

In the organic fertilizer granulator, dry granulation has lower energy consumption than wet granulation and is more environmentally friendly. It does not need to be dried, and does not add water and binder, so the material properties will not be changed. This is also the difference between dry granulation and wet granulation. Dry granulator machine is more suitable for industrialized mass production.

There is also a case that some materials require relatively small particle size, and products between tens of mesh and 100 mesh can also be reduced by airflow, spray, and flash drying.
