NPK fertilizers NPK fertilizers are high in NPK elements. Compared to organic fertilizers, NPK fertilizers are faster. In modern agriculture, NPK fertilizers are absolutely essential nutrients. The NPK fertilizer industry has a bright future.

Fertilizers produced by npk fertilizer production line are made from powdered chemical materials containing nitrogen, phosphorus and potassium. Typically, urea, ammonium chloride, calcium nitrate, ammonium sulfate can be used as nitrogen sources. More importantly, phosphorus，monoammonium acid, diammonium phosphate, calcium magnesium phosphate and triple superphosphate are commonly used to provide elemental phosphates. In addition, the potassium source of NPK fertilizer includes potassium chloride, potassium salt, potassium sulfate, etc.

Npk manufacturing process consists of crusher, fertilizer mixer, granulator (double roller granulator, rotary drum granulator, etc.), screening machine, fertilizer coating machine, fertilizer automatic packaging machine, etc.

At present, the actual utilization rate of chemical fertilizers in my country is only 30%-45%, and even lower in some areas. After the application of organic fertilizers, beneficial biological activities improve soil structure and increase the soil’s ability to retain water and fertilizer, thereby reducing nutrient loss. The effective utilization rate of chemical fertilizers has been increased to more than 50%. And can reduce the amount of chemical fertilizers and fertilization costs. Therefore, the fertilization method of “mainly organic fertilizer, supplemented by chemical fertilizer” is a more reasonable fertilization method at present.

Organic fertilizers are the energy of microbial life, so chemical fertilizers are inorganic nutrients for microbial growth and development. The two combine the vitality of microorganisms to further decompose organic fertilizers. The activities of soil microorganisms can also produce vitamins, biotin, niacin, etc. Increase soil nutrients, improve soil vitality and crop growth. NPK fertilizers are used in conjunction with organic fertilizers to coordinate soil nutrients and promote crop growth.

Manure and straw can be prepared using an organic fertilizer turner through composting technology. The following are the specific preparation methods:

Preparation of raw materials: Mix manure and straw in a certain proportion, usually with a ratio of 3:1 or 4:1.

Adjust moisture: Add an appropriate amount of water to the mixture to maintain its moisture content between 40% and 60%.

Adjusting the carbon to nitrogen ratio: By adding other organic materials or chemicals, the carbon to nitrogen ratio of the mixture is adjusted to an appropriate range to facilitate the growth and fermentation of microorganisms.

Composting: Stacking the mixture in a fermentation tank or tower for natural fermentation. During the fermentation process, microorganisms decompose organic matter into stable humus and release heat.

Flipping: During the fermentation process, it is necessary to use an organic fertilizer flipping machine to regularly flip the pile to promote the decomposition of organic matter and the formation of humus.

Drying: After fermentation is completed, remove the humus, air dry it, and then use an organic fertilizer crusher to crush it into powder or granules.

Packaging: Pack the dried organic fertilizer for sale or use.

In the process of preparing organic fertilizers from manure, straw, etc., the following points need to be noted:

Selection and treatment of raw materials: Fresh and harmless feces and straw are selected, and pre-treatment is carried out, such as removing impurities, crushing, etc.

Adjusting moisture and carbon nitrogen ratio: Based on the properties of the raw materials and local natural conditions, adjust the moisture and carbon nitrogen ratio of the mixture appropriately to facilitate the smooth progress of the fermentation process.

Control temperature and oxygen: During the fermentation process, it is important to control the temperature and oxygen content to avoid the growth and reproduction of harmful microorganisms.

Flipping and drying: During the fermentation process, regular flipping is necessary to promote the decomposition of organic matter and the formation of humus. After fermentation, the humus should be taken out and dried, and then crushed into powder or granules.

Packaging and storage: The packaged organic fertilizer should be stored in a dry and ventilated place to avoid problems such as moisture and mold.

Working principle: The organic fertilizer rotary drying furnace adopts patented technology and uses the principle of low-temperature hot air for drying. The equipment is equipped with a high-quality heating system and fan system inside, which sends hot air into the equipment through the heating system. Organic fertilizer is dried inside the equipment by rotating, and the fan system helps to circulate hot air, evenly heating the organic fertilizer, accelerating water evaporation, and ultimately achieving the drying effect.

Advantages: The organic fertilizer rotary drying furnace has the advantages of high efficiency, energy conservation, and uniform drying. Compared to traditional high-temperature drying methods, low-temperature hot air drying can retain the nutrients in organic fertilizers to a greater extent and improve product quality. At the same time, the equipment adopts a closed loop operation to reduce the loss of hot air and save energy. In addition, the rotary drying method allows organic fertilizers to be uniformly heated, avoiding the problem of incomplete drying of some organic fertilizers caused by uneven heating in traditional drying equipment.

It should be noted that organic waste such as cow and sheep manure may contain harmful substances such as heavy metals. Therefore, when producing organic fertilizers, it is necessary to pay attention to the safety and quality of raw materials, and conduct necessary testing and control. In addition, in order to improve the quality and efficiency of organic fertilizers, an appropriate amount of additives can be added, such as nutrients such as nitrogen, phosphorus, potassium, and bioactive substances.

The npk manufacturing process can usually be divided into: raw material batching, raw material mixing, raw material granulation, particle drying, particle cooling, particle classification, finished product coating, and final product packaging. The complete set of equipment has less investment, quick effect and good economic benefits. The complete set of equipment has a compact process layout, is scientific and reasonable, saves energy and reduces consumption, and has stable and reliable operation.

In the fertilizer production process, a factor that is not well controlled will affect its organic fertilizer effect. In the field of continuous bulk solids processing equipment, residence time may be one of the most influential variables in process settings, especially in rotary dryers, rotary kilns , rotary drum granulator, or other types of drums when processing materials.

Residence time is the amount of time a material is processed in a given facility. In most process settings, a specific retention time must be able to be achieved to achieve its intended goal. For example, the need to achieve a specific moisture content, initiate or complete a chemical reaction or phase transition, form particles within a desired particle size distribution, etc.

For example, in terms of quality, a spin dryer without a proper understanding of the retention time can cause the material to reach the target moisture level prematurely in the drum, meaning the material will continue to dry for the remainder of the time. This can cause the material to overdry and break down into fine powder. Likewise, if the drum is not long enough to accommodate the necessary retention time, the material may exit the drum before reaching the desired moisture content, still not reaching the desired target particle size. In other cases, the quality may not be compromised, but the drum size may be too large, resulting in reduced efficiency. Therefore, in the production process of the npk fertilizer production line, it is necessary to control the time rhythm and pay more attention to the temperature, humidity, size and shape of the material.

The production process of organic fertilizer mainly includes steps such as raw material treatment, fermentation, dehydration, crushing, screening, and packaging.

Firstly, raw material processing is a very important step. The main raw materials for organic fertilizer include animal manure, plant straw, and fruit peel. These raw materials need to be cleaned and crushed for better fermentation.

Next is the fermentation stage. Mix the processed raw materials with microbial strains and place them in the compost yard for fermentation using an organic fertilizer turner. During the fermentation process, microbial strains will decompose organic matter, produce organic acids, ammonia and other substances, and release and stabilize nutrients in organic fertilizers.

Then comes the dehydration step. After fermentation, organic fertilizer will have a certain moisture content. In order to improve the quality of organic fertilizer and facilitate storage and transportation, it needs to be dehydrated. Typically, equipment such as centrifuges and filter presses are used for dehydration to reduce the moisture content of organic fertilizers.

Next is fragmentation and screening. The dehydrated organic fertilizer needs to be crushed using an organic fertilizer crusher to make the particles finer and improve the nutrient release efficiency. At the same time, screening is also necessary to remove impurities and ensure the purity and quality of organic fertilizers.

Finally, there is the packaging process. The organic fertilizer processed through the above steps will be packaged as needed for easy storage and sales.

The above is the main process flow of the organic fertilizer production line, and each step is very important. It is necessary to strictly control the quality and operational requirements of each link in order to produce high-quality organic fertilizer products.

The supporting equipment for small-scale organic fertilizer production lines mainly includes:

Fermentation tipping machine: used to evenly stack materials, increase the contact area between materials and air, and promote the fermentation process.

Crusher: The fermented material is crushed for subsequent granulation and packaging.

Fertilizer mixer: Mix and stir the crushed materials to ensure their uniformity.

Fertilizer granulator: Granulates the mixed material to form the desired shape of particles.

Drying machine: Drying the granulated particles to reduce moisture content and improve particle stability.

Cooling machine: Cools the dried particles to a suitable temperature and humidity.

Screening machine: screens the cooled particles to remove particles that do not meet the requirements.

Packaging machine: Packaging qualified particles after screening for storage and transportation.

The quotation for a complete set of organic fertilizer processing equipment is generally between 200000 and 5 million depending on the configuration. The specific quotation needs to be compared with the actual needs and the manufacturer’s quotation to select the most suitable equipment configuration scheme. It is recommended to understand the market situation and manufacturer’s strength before purchasing, in order to better choose the equipment that suits oneself.

Livestock and poultry manure contains a large amount of nitrogen, phosphorus and other substances, which will not only pollute the surface water, but also pollute the groundwater if it penetrates into the ground, which has a great impact. Once the water is rich in a large amount of nitrogen and phosphorus, it will lead to eutrophication of the water quality, and aquatic plants such as algae will grow in large quantities, robbing aquatic organisms for oxygen, resulting in hypoxia in the water, resulting in the death of a large number of aquatic organisms.
