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.

FPC disc granulator has the following advantages: high spheroidization rate, high roundness and strength of particles, intuitive operation, convenient maintenance, etc.

The working principle of the disc granulator: The powdered fertilizer is evenly moistened by the atomized water in the double-shaft mixer to form a spherical core with a uniform particle size, and then sent to the spherical disc for granulation. The moisture content of raw materials should be controlled at 12~14%. Most of the water should be added in the double-shaft mixer, and only a small amount of supplemental water should be added to the ball pan, and the supplemental water amount should be controlled at about 0~3%. Dry powder granulation is directly added to the ball-forming disc, and an appropriate amount of water is sprayed. After the raw material ball core enters the ball-forming disc, it moves along a parabola under the action of centrifugal force, friction and gravity in the disc. Due to the cohesiveness and plasticity of the material, the cores adhere to each other and gradually grow up during the movement. When the inclination angle of the ball disc, the high speed of the disc edge and the water content are constant, the material balls of different particle sizes will leave the disc edge and roll down at different detachment angles due to different gravity. The material ball continuously pushes the water out of the surface during the continuous rolling process. Due to the cohesiveness of the material and the natural volatilization of the surface liquid film, the material ball has a certain strength, and then with the rotation of the inclined plate body The edge of the disc is discharged out of the disc.

Stirring-teeth granulator:

The new type of organic fertilizer granulator is also called a spiral stirring tooth structure due to its internal structure , Granulation, spheroidization, densification and other processes, so as to achieve the purpose of granulation. The particle shape is spherical, the particle size is generally between 0.3-3 mm, and the granulation rate is 90%. The size of 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 higher the rotation speed, and the larger the particle size. Small, and vice versa. Application range: This 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. It is generally required that the particle size of the material before granulation should be less than 200 mesh. Typical application materials: chicken manure, pig manure, cow manure, carbon black, clay, kaolin, etc.

It is dedicated to the granulation of municipal solid waste organic fermented fertilizer such as manure, compost, green manure, sea manure, cake manure, grass charcoal, soil and miscellaneous manure, three wastes, microorganisms, etc. The particles are spherulites. The granulation rate of the machine is as high as 80-90%, and it is suitable for a variety of different formulas. The compressive strength of organic fertilizer is higher than that of discs and drums. The rate of large balls is less than 15%. The uniformity of particle size can be customized according to user requirements. It is adjusted through the stepless speed regulation function of this machine. This machine is suitable for the direct granulation of organic fertilizer after fermentation, which saves the drying process and greatly reduces the manufacturing cost.

Animal manure is a kind of high quality organic fertilizer, known as the “king of organic fertilizer”. Manure has good long-term fertility, ventilation, drainage and water retention, and comprehensive nutrients. It not only contains nitrogen, phosphorus, zinc and other elements, but also contains iron, manganese, zinc, copper, magnesium and other trace elements and 18 kinds of amino acids. The content of organic matter and humus can reach about 30%. At the same time, there are about 100 million beneficial bacteria per gram. What’s more valuable is that they contain antagonistic microorganisms and unknown auxin. Through the role of probiotics, it can effectively inhibit the growth of pathogenic bacteria in soil and inhibit the occurrence of soil borne diseases. So how to use animal manure to produce organic fertilizer?

One is raw material fermentation

Firstly, the required materials are mixed, and tank aerobic fermentation process or strip composting fermentation can be used to make the materials soft. After fermentation and decomposition of raw materials, harmful microorganisms and insect eggs in raw materials can be killed in the high temperature stage of fermentation to prevent their adverse effects on the growth of animals. The quality of raw material fermentation is directly related to the yield of animals, so we must pay attention to it.

After the trampoline is finished, put the fermented materials on the trampoline and stack them about 20 cm high. Each square can raise 1-2 million animals, and feces and cockroaches can be collected every 10 days.

Collection of feces

Faeces are usually collected at the same time as animals are harvested. The collection of feces is mainly based on the characteristics of being afraid of the sun. First of all, put cockroaches and feces in a sunny place and keep drilling down, so that you can collect sputum layer by layer. The second is to use mechanical separation method to separate sputum, feces and mechanical separation method, and then collect sputum.

Animal manure fermentation

The fermentation tank is used for continuous fermentation of sputum, and feces are mixed with fermentation bacteria. The excrement in the tank is turned by the dumper once a day, and the fresh excrement is fed from the side of the tank, and the fermentation is completed. The material is sent out from the other end of the groove.

Fecal dryness

The moisture content of the harvested feces is about 40%. Generally, natural drying method and artificial drying method are used.

At this time, feces can be used directly. If you want to make more money, you can also use the organic fertilizer production equipment for further granulation and packaging of feces.
