Author: organic fertilizer production line

NPK compound fertilizer is a multifunctional fertilizer that contains three main nutrients: nitrogen, phosphorus, and potassium, which can meet the nutritional needs of crops at different growth stages.

Equipment process flow of NPK compound fertilizer production line:

Usually includes raw material pretreatment, material batching, hopper lifting, mixing and homogenization, particle granulation, drying, screening and other processes. In this process, different devices are involved in each link.

Firstly, the pre-treatment stage of raw materials involves cleaning, crushing, screening, and other processes to ensure the purity and particle size uniformity of the raw materials. Then, in the material ingredient stage, various raw materials are mixed in a certain proportion to ensure a balanced nutritional composition of the final product.

Next, the prepared materials will be transported to the mixing and homogenization equipment through a hopper elevator, which can fully mix and evenly distribute the materials. After the mixing and homogenization is completed, the material will enter the granular fertilizer granulator and be compressed into granules through the granulation process.

Finally, the particles will enter the fertilizer dryer for dehumidification treatment, and then pass through screening equipment for classification to obtain products of different specifications.

The above is a brief introduction to the process flow of NPK compound fertilizer production line equipment. There are various types of equipment involved in this process, but they all have their own characteristics and can effectively complete tasks in each link.

The organic fertilizer production line equipment includes: fermentation turner, crusher, feeder, horizontal mixer, double roller granulator, dryer, cooler, screening machine, weighing and packaging machine. Let’s take a look at the trommel screening machine. The trommel screening machine is a new generation of professional equipment for self-cleaning materials after the electric vibrating screen and the general mesh vibrating screen manufactured by major enterprises. It is generally suitable for the screening of solid materials with a particle size of less than 300mm. It has the characteristics of high screening efficiency, low noise, small dust volume, long service life, small maintenance, and convenient maintenance. It can be used in organic fertilizer and npk production line, etc, and its screening capacity is 60 tons/hour~1000 tons/hour.

Features of rotary screener machine:

(1) The screening efficiency is high, because the equipment is equipped with a plate screening mechanism. During the screening process, no matter whether the material entering the separation screen is sticky, wet or impurity, the relative movement of the screening machine and the screen body cannot stop the screening. Thus, the screening efficiency of the equipment is improved.

(2) The entire screening mechanism with a good working environment is designed in a sealed dust jacket, which completely eliminates the phenomenon of dust flying during the screening process, thereby improving the working environment.

(3) When the low-noise equipment is running, the noise formed by the material and the rotating screen is completely isolated by the sealing dust jacket, so that the noise cannot be transmitted to the outside of the equipment, thereby reducing the noise of the equipment.

(4) The equipment screen with long service life is composed of several round flat steels with a size of 16 mm × 12 mm, and its cross-sectional area is much larger than that of other separation equipment screens, thereby improving the service life.

Organic fertilizer is a common fertilizer, and now it is also a fertilizer strongly supported by the country. The use of chemical fertilizers is no longer advocated because the excessive use of chemical fertilizers has led to increasingly serious soil compaction. Promoting organic fertilizer is to solve soil compaction, increase soil organic matter and fertility, and organic fertilizer equipment is specialized in producing organic fertilizers. Therefore, the market for organic fertilizer equipment is very hot. In addition, the production of organic fertilizer requires fermentation to form. Below is an understanding of the granulation process of organic fertilizer equipment production lines:

1、 Mixing of ingredients

The organic fertilizer equipment uses two mixers to operate alternately. The operating formula puts N, P, K, M, additives, trace elements, etc. into the mixer, and after mixing evenly, they are placed on the conveyor belt to achieve continuous production and reduce the labor workload of workers.

2、 Mixed crushing

In this process, a horizontal crusher is used, which can crush large particles in the raw materials and fully mix them.

3、 Organic fertilizer equipment granulator

The choice of granulation method is very important in the production of organic fertilizer. There are various methods in the industry, such as disc, drum, and extrusion, which have stable performance and long service life. They can produce both organic fertilizer and inorganic fertilizer as well as organic-inorganic compound fertilizer. In this process, a new type of organic fertilizer granulation machine is selected.

4、 Drying

After granulation, most particles will form, but they will still contain water and must be dried. A dryer can achieve the effect of drying materials.

5、 Cooling

After drying, the material is transported by belt to the cooling machine. The rotary cooling machine is also a rotating cylinder filled with lifting plates. Under the action of the plates, the granular material is lifted and exchanges heat with the cold air sucked into the cylinder, cooled to near room temperature, further improving the particle strength and reducing moisture.

6、 Screening

After cooling, there are powdery materials present. The fine powder and large particles are all screened out using a screening machine. The fine powder is directly returned to the mixer and mixed with the raw materials through a return belt conveyor before participating in the granulation process again. After the large particles are crushed, they are returned to the mixer through the same return belt conveyor as the fine powder, forming a complete production cycle, and the finished product enters the packaging process.

7、 Organic fertilizer equipment packaging machine

Qualified finished products are packaged using a manual weighing scale or an automatic packaging machine.

The organic fertilizer equipment production line generally consists of multiple links, including raw material processing, fermentation processing, drying processing, and packaging. Firstly, organic raw materials are processed and sent to fermentation equipment for biological fermentation. Through the action of microorganisms, organic matter is transformed into organic fertilizer. Then, the fermented organic fertilizer will be dried to achieve appropriate moisture content and particle size for storage and use. Finally, after packaging and quality inspection, organic fertilizers can be officially launched into the market.

Organic fertilizer production equipment is generally divided into granular fertilizer production lines and powder fertilizer production lines, and the price difference between the two is as follows:

Production line for equipment with an annual output of 50000 tons of granular organic fertilizer:

The complete set of granular organic fertilizer production line equipment roughly includes: raw material crushing equipment – fermentation equipment – screening equipment – granulation equipment – drying equipment – cooling equipment – screening equipment – coating equipment – packaging equipment – conveying equipment, etc. The annual production of 50000 tons of granular organic fertilizer production line equipment varies depending on the configuration and degree of automation, with prices ranging from approximately 800000 to 3 million yuan;

Production line for equipment with an annual output of 50000 tons of powdered organic fertilizer:

The equipment for powdered organic fertilizer is relatively simple, mainly including raw material crushing equipment, fermentation equipment, screening equipment, packaging equipment, conveyor equipment, etc. The annual production of 50000 tons of powdered organic fertilizer production line equipment varies depending on the configuration and degree of automation, and the price is approximately 300000 to 600000 yuan

However, due to factors such as brand, materials, equipment configuration, specifications, and market, the price difference will also be relatively large. Therefore, it is necessary to have a comprehensive understanding and comparison before choosing to purchase organic fertilizer production equipment.

Whether it is an npk production line or an organic fertilizer production line, the basic equipment includes: crusher, feeder, horizontal mixer, fertilizer granulator, dryer, cooler, screening machine, weighing and packaging machine. Common organic fertilizer granulators include: double roller granulator, stock granulator, disc granulator machine, new organic fertilizer granulator, etc. During the production process of the fertilizer production line, the fertilizer must be transported , then you need a conveyor. Common conveyors include: belt conveyors, bucket elevators, large inclination belt conveyors, screw conveyors, etc. Today, let’s take a look at the reasons for the failure of bucket elevators.

Since the bucket elevator is started and used through the operation of the switching power supply, it is difficult to avoid problems on the motor during use. When the bucket elevator motor is abnormal. Please don’t panic. In this case, close the program as soon as possible. Find professional technicians to investigate common faults and find out the main cause of the problem. The following is a detailed description of the reasons for the failure of the bucket elevator motor, hoping to help you.

1. If the power of the motor you use does not match the bucket elevator you configured, the working voltage is too low, the raw materials cannot be transported normally, and the machine is likely to suspend operation. At this time, the motors must be disassembled and replaced to find all the motors that are consistent with the operating power of the bucket elevator.

2. Check whether it is the cause of poor installation quality or the difference between the motor and the spindle of the machine tool. Check if the motor is overheating when clearing installation common problems, based on a specific search by engineering construction technicians. If power engineering is popular, consider whether it is caused by excessive use time, and need to analyze detailed problems in depth.

3. Check whether the pressure of the packing screw cap is too tight or the adjustment of the mechanical seal torsion spring is too tight, and adjust the reduction of the screw cap or the mechanical seal torsion spring again.

One is, “the prospect of microbial fertilizers is very good.” For decades, the United States has drawn a conclusion from a large amount of data: “microorganisms can feed the world.” In the United States, using a reasonable microbial population reduces the use of chemical fertilizers by about 20%. Not only can the output be increased, but the quality can also be improved.

Second, the inorganic nutrient elements are composed of compound microbial fertilizers, organic matter, and microbial bacteria. The combination of inorganic fertilizers, organic fertilizers, and microbial fertilizers is to solve the phenomenon of soil hardening, repair and adjust the soil, and improve the quality of agricultural products.

Balanced supply of rapid nitrogen, phosphorus, potassium and various trace elements required for crop growth can strengthen the soil microbial system, exert a lasting effect, have a significant effect on increasing production, improve crop resistance, improve fertilizer utilization, and reduce river pollution , to reduce the occurrence of pests and diseases.

For the production of compound fertilizers, a double roller granulator is essential. What equipment is needed in addition to the double roller granulator to produce compound fertilizers?

Compound fertilizer granulation press granulator, what supporting equipment is needed for compound fertilizer granulator? Roll extrusion granulator is the main equipment for compound fertilizer granulation of powder materials. In addition to the roller extrusion granulator, the entire npk fertilizer production line also needs automatic batching machines, mixers, vertical pulverizers, drum screening machines, dryers, coolers, secondary drum screening machines, and automatic packaging scales. Belt conveyor connection.

The principle of the double-roll extrusion granulator: The double roller granulator adopts two rollers, leaving a certain gap (adjustable) between each other, and the two reverse at the same speed. There are many arc grooves of the same shape and size on the surface of the roll. According to the difference of the target compression ratio of the material, the trough of the arc groove of one roll is selected to be aligned with the trough of the other roll. The two rollers are horizontally parallel, and the powdery material is continuously fed from the top of the two rollers, evenly relying on self-weight and forced feeding between the two rollers. When the material enters the bite, it is gradually bitten by the roller. With the continuous rotation of the roll, the space occupied by the material is gradually reduced and compressed.

The broad application prospects of BB fertilizer production line

The BB fertilizer production line, as a modern fertilizer production solution, has broad application prospects.

Agricultural production: BB fertilizer can be widely used in the production of various crops, including vegetables, fruits, grain crops, etc. Through customized production and precise regulation, it is possible to provide nutrient supply suitable for different crops and growth stages, thereby improving crop yield and quality.

Greenhouse planting: In greenhouse planting, BB fertilizer can better meet the nutrient needs of plants in a controlled environment. By using water-soluble fertilizers, precise fertilization can be achieved, avoiding excessive fertilization and nutrient waste, and improving the yield and quality of greenhouse crops.

Environmentally friendly agriculture: The application of BB fertilizer production lines can reduce environmental pollution during traditional fertilization processes. The use of water-soluble fertilizers reduces nutrient loss and waste, while also reducing pollution to water sources. By reducing the use of pesticides and fertilizers, the pressure of agriculture on the environment can also be reduced, achieving sustainable agricultural development.

Production examples and main equipment of granular potash fertilizer equipment.

Granular potash fertilizer production equipment raw materials: powdered potassium oxide (0-0-60) or powdered potassium sulfate (0-0-50); magnesium chloride, magnesium sulfate, magnesium oxide bitter soil powder: fillers, including clay, bentonite, gypsum, etc. 

(1) Stir and dissolve human water, magnesium oxide (or ferric sulfate), magnesium oxide (or ferric sulfate), and potassium fertilizer production equipment into a solution, then add powdered magnesium oxide in a certain proportion, and stir evenly to form the required magnesium hydroxide hydrate (or sulfate hydrate).

(2) Potassium fertilizer production equipment add powdered potassium chloride or potassium sulfate to a rotary drum granulator or a double roller granulator, and spray wine in proportion. Hydrated magnesium oxychloride (or hydrated magnesium oxysulfide) is a granulation aid, and the addition amount is 0.5%~10.0% by dry weight. At the same time, the potash fertilizer production equipment can continuously granulate into balls through steam, and then dry, cool, and sieve to obtain the finished granular potash fertilizer.

The main equipment for granular potassium fertilizer production is dry powder granulator (double roller granulator), which is mainly equipped with forced eye feeder, rolling unit, frame platform, crusher, multi-stage screening machine, bucket elevator machine, electrical control cabinet. The dry powder granulator has reasonable design, compact structure, simple process and convenient operation. Powder raw materials can be directly processed into uniform particles of 0.5~5mm without any additives, which greatly increases the bulk density of materials, reduces consumption, controls environmental pollution, reduces packaging costs, and improves the working environment for workers. Our organic fertilizer equipment manufacturer specializes in the production of organic fertilizer equipment, including npk fertilizer production line, organic fertilizer production, etc.

Whether it is in the organic fertilizer production line or npk fertilizer production line, after the organic fertilizer granulator (roller granulator, disc granulator, drum granulator, etc.), the fertilizer granules will have moisture. How to find a way to deal with the granules What should I do if the moisture of fertilizer granules is too high after granulation? Then we will use coolers in the production of organic fertilizer production equipment. The cooler is the main equipment of the production system on the fertilizer processing line, with a simple structure and good stability.

The cooling equipment is specially designed for the needs of producing granular organic fertilizers and can be used in npk production line and organic fertilizer production lines. In the production of granular organic fertilizer, the granular organic fertilizer produced by the granular press needs to go through a cooling process to achieve the purpose of cooling and dehydration. In the existing equipment configuration, there are mainly two kinds of granular organic fertilizer cooling equipment, one is vertical cooler and the other is reverse flow cooler. The principle is that the temperature of the pellets produced by the pellet press is relatively high, generally 70~80°C. Through the cooling process of the cooler, the material can remove about 3 percent of water, which can meet the requirements of cooling and drying under ideal conditions.

The cooler is the main equipment of the production system on the fertilizer processing production line, with simple structure, good stability and reliable rotation. The waste gas after heat exchange can be introduced into the rotary kiln to improve the thermal efficiency of the whole system. Also known as drum cooler, it is used for the production of organic fertilizer and npk manufacturing process, cooling the fertilizer of a certain temperature and particle size, used together with the dryer. It can greatly improve the cooling speed, relieve labor intensity and improve efficiency. Further remove part of the water and reduce the grain temperature of the compound fertilizer. It can also be used for other powder. Granular material cooling. The cooling equipment has compact structure, high cooling efficiency, reliable performance and strong adaptability.
