What are the granulation equipment and methods for NPK fertilizer production line

fertilizer granulator Nov 10, 2023

There are four types of granulation in the NPK fertilizer production line on the market: 1. Disc granulation is suitable for small output devices, and generally does not exceed 50,000 tons/year. It is the primary stage of drum npk fertilizer granulation. 2. The drum npk fertilizer granulator is widely used, and the pellet size is also better, including drum ammoniation granulation and drum agglomeration granulation. Among them, the ammoniation is divided into one-step ammoniation and two-step ammonia The two-step amination method includes the amination reaction in the conversion tank and the amination reaction in the granulator. 3. Shotcrete granulation is the predecessor of ammoniated granulation and the technology is relatively mature. 4. High-tower granulation means that the raw materials are sprayed through the high-tower in a molten state at a high temperature. The pellets are formed into pellets during the falling process. The pellets are relatively strong and smooth. The pellets generally have a small hole, dissolve faster, and have obvious fertilizer efficiency. The market prospect is better. 

The rotary drum npk fertilizer granulator sprays water vapor at a constant pressure on the material, so that the material obtains moisture while being applied with a constant pressure to form small particles, which are formed into particles of a fixed size during the process of rotation. The humid granulation environment allows the drum granulator to produce a compound with a high content of nitrogen, phosphorus and potassium, but the cost is relatively low.
Advantages of the drum npk fertilizer granulator: By increasing the granulation temperature, the liquid content in the basic material is increased, which promotes the material to form a ball at a lower water content, and has the advantages of easy drying, energy saving, and consumption reduction.
Disadvantages of drum npk fertilizer granulator: When the process conditions are not well controlled, the return material is higher than that of the disc granulator.

Cow manure is fermented and processed into organic fertilizer, which not only achieves waste reuse but also reduces the production investment cost of farmers. High degree of harmlessness, improved soil, beneficial for absorption, slow and efficient, increased production and income, fertilized soil fertility, balanced nutrition, low production cost of biological composite bacterial agents, can improve soil, improve crop product quality, and increase crop yield. It is commonly used for various economic crops and food crops such as fruits, vegetables, fruit trees, grass, tea, etc.

Process steps for producing granular organic fertilizer from cow manure

Step 1: Fermentation and Maturation

Collect cow manure and urine, mix them with straw, hay, and other ingredients to control the moisture content by about 65%. Stack the materials into strips with a width of no less than 10 meters and a width of 2-5 meters. Sprinkle 1KG of aerobic fermentation bacteria with 2-3 cubic meters. Mix thoroughly with a wheeled composting machine and let them ferment. After fermentation, use a composting machine to cool the materials.

Step 2: Material crushing

Crush the organic raw materials of fermented and decomposed cow manure. Organic fertilizer wet material crusher is a professional crushing equipment for high humidity, multi fiber materials. Utilizing high-speed rotating chains to crush fibers with good particle size.

Step 3: Mixing and stirring

Add trace elements, excipients, humic acid, clay, etc. for mixing and stirring. Using a vertical mixer, the mixing speed is fast and the uniformity is good. It can mix viscous materials with a liquid content of 30%. During operation, there are two opposite rotating blades and rotors stirred in the middle. Adopting a lower door for fast unloading speed and minimal residue.

Step 4: Forming and granulation

The material is granulated using a disc granulator, an organic fertilizer stirring tooth granulator, or a new type of stirring tooth rotating strand three combination granulator.

Step 5: Drum drying

The organic fertilizer dryer further removes moisture from the granulated particles to meet the standard requirements for organic fertilizer moisture content.

Step 6: Drum cooling

Cooling the dried granular material with a cooling machine helps to preserve the quality of the particles.

Step 7: Screening and return system

Due to the differences in particle size of the granulated material output from the granulation and forming system, screening and grading are required. The selected drum type screening machine requires low vibration, low noise, convenient screen replacement, and is equipped with a screen cleaning device.

Step 8: Particle coating equipment

The coating machine is composed of a screw conveyor, a mixing tank, an oil pump, a main engine, etc., and is used for powder or liquid coating technology. It can effectively prevent the caking of fertilizers, and the host is lined with polypropylene or acid resistant stainless steel.

Step 9: Packaging Equipment

Application of disc granulator in granular organic fertilizer production line

fertilizer granulator Nov 10, 2023

The disc granulator is suitable for granulating round fertilizer granules of compound fertilizer or organic fertilizer, which is convenient for transportation and storage. In order to produce fertilizer granules with balanced nutrition, a proper granulator is your ideal choice. We are a professional fertilizer factory and will provide you with practical guidance on fertilizer granulation.

The disc granulator takes the motor as the power to drive the inclined disc to rotate. The internal scraper prevents the material from sticking to the bottom of the disc. When the material rotates to the top, it will roll down by itself, just like a snowball. It is suitable for non viscous powder materials.
Some customers have seen the process of organic fertilizer processing and want to process feed pellets, but they don’t know whether the disc pelletizer is suitable. The answer is: yes. Because the characteristics of feed ingredients and organic fertilizer ingredients are basically similar, this equipment is wet granulation, which has a wide range of applicable raw materials. When we use the disc granulator for processing, sometimes the particles are larger and sometimes smaller. The way to solve this problem is to adjust the moisture of the material.
When purchasing an organic fertilizer granulator machine, customers must choose a manufacturer with a certain technical strength and perfect after-sales service. Nowadays, there are many companies producing organic fertilizer granulators in the country, and some companies have no technology at all, and they are completely imitated by other manufacturers. During production, the quality of the organic fertilizer granulator machine manufactured is not up to standard, and some of them cannot be used normally.

How to select suitable organic fertilizer production equipment for farmers based on their scale

fertilizer granulator Nov 10, 2023

How should farmers configure suitable organic fertilizer production equipment based on their breeding scale? Firstly, the livestock and poultry manure generated by the scale of breeding needs to be sufficient for the normal fermentation production of the organic fertilizer production line. The production capacity of the organic fertilizer production line is very large, producing 2-20 tons of organic fertilizer per hour.

If the production scale of livestock farms is too small and poultry manure is used as the raw material for organic fertilizer production, the raw material for organic fertilizer will be insufficient. Joining the introduction of an organic fertilizer production line would result in most of the equipment being in a stagnant state, which is clearly not cost-effective. We all know that the water content of poultry and livestock manure is relatively high, and the water content requirement of organic fertilizer cannot be higher than 30%. Therefore, the amount of poultry and livestock manure required to produce one ton of organic fertilizer should be higher than one ton. If the scale is insufficient, simple composting fermentation can be directly returned to the field. If the labor of composting is too strong, organic fertilizer flipping machines can be used.

The whole machine of the chicken manure organic fertilizer tipping machine adopts high-strength chain transmission, hydraulic control lifting, and this machine adopts a unique track design, which can use multiple slots and one machine. This not only changes the shortcomings of low production of traditional light rail tipping machines, but also overcomes the high cost of transmission accessories for conventional gear racks and light rail driving tipping machines.

The chicken manure fermentation and tipping machine has the characteristics of good maneuverability and high output rate, which can effectively improve labor productivity, save manpower, and achieve the goal of reducing production costs and improving product quality; It is a new type of product with low investment and high returns; It also has functions such as stirring and crushing, and is an essential key equipment for fertilizer making enterprises. It largely replaces manual operations, reduces human labor, and improves work efficiency.

Which type of granulator is commonly used in the NPK compound fertilizer production line for granulation

fertilizer granulator Nov 7, 2023

The first is NPK fertilizer granulator to produce compound fertilizer, so that the gas-liquid raw materials are absorbed and solidified, so that large particles and large pieces of solid raw materials are broken into fine powder, which is wrapped to form high-density particles with good fluidity, so as to prevent the powder from bridging and hardening due to moisture absorption, mutual electrostatic attraction, large contact area and other reasons, and also avoid the difficulty of gas-liquid raw materials storage and subcontracting, which is convenient for weighing , packaging and use.

Second: NPK fertilizer granulator makes the fertilizer form particles of appropriate size, which is conducive to the exertion of fertilizer efficiency. It avoids the disadvantages of bulk raw materials not easy to decompose, slow fertilizer efficiency, powder fertilizer easy to float and disperse, too fast decomposition and loss of fertilizer efficiency, and waste. At the same time, it also avoids the disadvantages of volatile gas-liquid raw fertilizer, easy to cause personnel poisoning and environmental pollution.
The granulation rate of npk fertilizer granulator is a combination of the amount of returned material and the particle size distribution of the returned material, the amount of liquid phase, the granulation temperature, the granulation time and other factors. The liquid phase content and temperature of the material from the granulator during operation also have a great influence on the granulation. If the liquid phase is not enough, the material will not bond into granules. If the liquid phase is too large, it will easily produce large particles, and the viscosity of viscous materials It has a lot to do with temperature. Generally, the higher the temperature, the greater the viscosity. When the temperature of the crystalline material is higher, the water is easy to volatile and easy to crystallize.

Process flow of an annual production line of 50000 tons of pig manure organic fertilizer

fertilizer granulator Nov 7, 2023

The powdered organic fertilizer produced by the pig manure powder organic fertilizer production line with an annual output of 50000 tons refers to the fertilizer produced by fermenting organic raw materials in a certain proportion without causing particles. There is a certain difference from traditional composting fermentation, with the standard being 40% organic matter, over 5% total nutrients, and 30% moisture. The equipment is also relatively simple, mainly consisting of the three stages of fermentation, namely pre mixing, flipping, refining, and packaging. The main purpose of fermentation is to decompose the macromolecular materials of organic raw materials into small molecule materials that can be absorbed and utilized by crops through microbial decomposition. The quality of fermentation is also related to the quality and effectiveness of organic fertilizers.

The large-scale pig manure organic fertilizer organic fertilizer production line with an annual output of 50000 tons roughly includes: raw material selection (chicken manure, etc.) → drying and sterilization → ingredient mixing → granulation → cooling and screening → measurement and sealing → finished product warehousing. The more complex production process of chicken manure organic fertilizer is as follows: the organic fertilizer raw materials (animal manure, household waste, dead branches and leaves, biogas residue, waste bacterial strains, etc.) are fermented and then crushed in a semi wet material crusher. Then, elements such as nitrogen, phosphorus, and potassium (pure nitrogen, phosphorus pentoxide, potassium chloride, ammonium chloride, etc.) are added to make the mineral elements meet the required standards, and then stirred by a mixer before entering the granulation mechanism for particles, After coming out, it is dried and screened by a screening machine. Qualified products are packaged, and unqualified ones are returned to the granulator for granulation.

With the vigorous development of sustainable agricultural production in China, organic fertilizer production line equipment will become increasingly popular in the market; In the process of continuous updating and upgrading of organic fertilizer equipment in the market, the use of organic fertilizer equipment has become a trend. When purchasing organic fertilizer equipment, it is necessary to determine different specifications and models based on different situations in order to maximize its effectiveness.

What are the factors that affect the price of organic fertilizer granulators?

There are many kinds of organic fertilizer granulator machine, such as disc granulator, new organic fertilizer granulator, drum granulator, double-roller extrusion granulator, etc. The most commonly used granulating equipment is just the above. In the production of organic fertilizer, the selection of granulator is usually determined according to many factors, such as raw materials, output, and price.
Disc granulator is mainly used for rolling ball granulation of powder homogeneous materials with good adhesion; Disc structure, gear transmission. The fertilizer granulator machine price is generally less than 30000 yuan.

The double roller granulator is suitable for granulation of compound fertilizer, medicine, chemical industry, feed and other raw materials with high granulation rate.
The new two in one organic fertilizer granulator uses the high-speed rotary mechanical stirring force and the resulting aerodynamic force to realize the continuous mixing, granulation, spheroidization and densification of fine powder in the granulator, 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 ~ 3mm, and the granulation rate is ≥ 80%. The size of particle diameter can be appropriately adjusted by the material mixing amount and spindle speed. Generally, the lower the mixing amount is, the higher the speed is, the smaller the particle is, and vice versa. The two in one granulator has the advantages of high granulation efficiency, no acute angle after granulation, low pulverization rate and easy to meet the requirements of large-scale production. The fertilizer granulator machine price is generally less than 80000 yuan.
Fertilizer granulator machine price is only an indicator in the process of purchasing a product or service. If you simply compare prices, it is not so thoughtful. Price, quality, service, word of mouth, suitability for your own situation, etc. all need to be considered together. If you want to know more details, you can consult Zhengzhou Huaqiang Heavy Industry Technology Co., Ltd.

Price of Different Fertilizer Granulators in NPK Fertilizer Production Line

fertilizer granulator Nov 7, 2023

The output of NPK fertilizer granulator is related to its specifications and models. Each model corresponds to a different output. How much is the price of NPK fertilizer granulator? We also choose the specifications of the production line according to our own production needs, so as to determine its price. We should not blindly pursue large output, we must choose according to our own production needs, so as to avoid insufficient supply of raw materials or excess production, resulting in the shutdown of machinery, resulting in low daily output, resulting in low economic benefits, so we must choose reasonable specifications and models.

In many NPK fertilizer production processes, NPK fertilizer granulator is used to make granules. Huaqiang heavy industry will simply introduce a drum type NPK fertilizer granulator.
The main working mode of the drum granulator is wet granulation of agglomerates. A certain amount of water or steam is used to make the basic fertilizer fully chemically react in the cylinder after the humidity is adjusted. Under a certain liquid phase condition, with the help of the rotating movement of the cylinder , So that the squeezing force between the material particles will reunite into a ball.
The cylinder of the machine adopts a special rubber plate lining or acid-resistant stainless steel lining plate, which realizes automatic scar removal and tumor removal, eliminating the traditional scraper device. The machine has the characteristics of high ball strength, good appearance quality, corrosion resistance, wear resistance, low energy consumption, long service life, and convenient operation and maintenance.

The Technology and Advantages of Crawler Type Scraper in Chicken Farms

fertilizer granulator Nov 7, 2023

The “wheel” of the walking type fermentation tipping machine for chicken manure organic fertilizer in the breeding farm is a coiled circular track supported on the ground. The track is in contact with the ground, and the spike is inserted into the soil, but the driver is not grounded. Under the action of driving torque, the driving wheel continuously rolls up the track from the rear through the meshing between the teeth on the driving wheel and the track shoe joint pin, thereby driving the movement of the entire tipping machine. This is the main power source of the tracked tipping machine.

The tracked manure flipper in a chicken factory is a four in one multifunctional flipper that integrates fermentation, stirring, crushing, and displacement. The rotating blade shaft inside the flipping and throwing is used to mix, fluff, and move the raw materials in the pile. The outstanding technology of the crawler type tipping machine is the integration of the material crushing function in the later stage. With the gradual dehydration of materials and the installation of crushers, the main goal is to greatly improve the efficiency of crushing, reduce costs, and fundamentally solve the problem of production volume being restricted by crushers.

There are differences between the tracked walking type fermentation tipper and the wheeled tipper for chicken manure organic fertilizer in breeding farms. The wheeled tipper has environmental limitations (the ground must be flat and free of obstacles), while the tracked tipper is not affected by the surrounding environment and can operate on the farm anytime and anywhere, greatly improving the efficiency of flipping and fermentation.

The crawler mounted fermentation and tipping machine for organic manure from poultry farms has excellent work efficiency and cost-effectiveness. The crawler type can cross obstacles, slopes, ridges, etc., without being affected by road conditions. In order to better cope with various harsh environments and complete the work better. The track type has good grip and flexible steering. There will be no slipping, drifting or other situations when walking.
