• Specialty Blends: Custom blends tailored for specific plants or growth stages, such as tomato fertilizers or starter fertilizers for new lawns.

What is the process flow of making NPK compound fertilizer?

NPK fertilizer is made through a combination of chemical and physical processes like granulation/drying/cooling/coating/screening to ensure the right balance of nutrients. Here's a general overview:

1. Raw Material Preparation:

The first step in fertilizer production is the preparation of raw materials, including nitrogen from ammonia, urea or ammonium nitrate; phosphorus from processed phosphate rock (such as phosphoric acid or superphosphate); and potassium from potash minerals (such as potassium chloride or potassium sulfate). These materials undergo chemical processing, including ammoniation (reacting ammonia with phosphoric acid to form ammonium phosphate) and neutralization (using acids and bases to form stable compounds). Compound fertilizer factories need to purchase these raw materials in bulk or powder form from the market for compound fertilizer production or use a chain crusher/bulk crusher/dap crusher to turn it from bulk to powder for further processing.

2. Granulation: Using steam drum granulator achieve material agglomeration

The drum granulator uses steam to achieve agglomeration of materials. Its working principle is to add raw materials such as fertilizer powder and water or steam into a rotating drum. Under the action of steam heating and drum rotation, the raw material particles bond with each other to form uniform particles. Usually, the temperature of the steam is controlled between 160°C and 200°C, and the pressure is maintained between 0.4MPa and 0.8MPa. In order to ensure the granulation effect, the amount of steam used varies according to the production volume and material characteristics, usually about 1 to 2 tons of steam per ton of material. This process not only ensures uniform particle size and smooth surface, but also effectively improves fertilizer storage, transportation and application effects. The drum granulator has many advantages: first, it can ensure the consistency and uniformity of the particles and meet the needs of precise fertilization; second, it uses steam heating to significantly reduce energy consumption; in addition, the drum granulator is suitable for It is suitable for large-scale production and has higher production capacity; it can also improve the quality of particles, because the steam process helps better bonding between particles, thereby reducing the production of fine powder.

3. Drying: remove the moistrue from the raw meal

Drying in compound fertilizer production line mainly removes moisture from fertilizer granules with excessive humidity to ensure the quality and stability of fertilizer. During the granulation process, fertilizer granules usually absorb a certain amount of steam moisture. The function of drying section is to evaporate this moisture with hot air generated by hot air furnace to reduce the moisture content of granules (generally controlled at 2-5%). Drying can not only reduce the humidity of granules, but also improve the hardness and strength of granules, ensuring the fluidity and use effect of fertilizer.

Cooling: Efficienctly prevent fertilizer moisture regain and prepare for coating.

The main function of the cooler is to quickly cool the hot fertilizer granules after drying to a suitable temperature to ensure the stability of the subsequent coating of the granules. By exposing the fertilizer granules to cold air, the cooler uses the principle of heat exchange to effectively remove the heat of the granules and reduce their temperature, usually to room temperature or 25-35°C. Cooling effectively avoids the problem of agglomeration caused by high temperature and ensures the fluidity of the fertilizer. In addition, the cooled fertilizer is more adaptable to environmental changes and prevents moisture from re-absorbing moisture, thereby improving storage stability.

Coating: Enhance the anti-caking and moisture-proof properties of fertilizers

The main function of the coating machine in the compound fertilizer production line is to add a protective coating to the fertilizer particles, usually to enhance the anti-caking and moisture-proof properties of the fertilizer and to improve its appearance. During the coating process, some anti-caking agents, moisture-proof agents or other functional coatings are usually used to form a thin film by evenly spraying them on the surface of the fertilizer particles. This film can effectively prevent the fertilizer from absorbing moisture and agglomerating, and improve the fluidity and storage stability of the fertilizer. At the same time, the coating can also provide protection for the fertilizer particles against weathering and hydrolysis. The working principle of the coating equipment is usually to fully contact the fertilizer particles with the coating metering oil and powdered anti-caking agent controlled by the DCS system through a high-speed rotating coating barrel to ensure that each particle can be evenly coated with a protective film. In this process, the spray system in the equipment will evenly spray the coating on the surface of the fertilizer particles, and at the same time help the coating dry through air flow to prevent the coating from sticking together. The surface of the coated fertilizer particles is smooth, the fluidity is better, and it is more suitable for packaging and storage. At the same time, it can effectively avoid agglomeration or water loss during transportation and use.

What are the advantage of NPK compound fertilizer steam drum granulation line?

• High production capacity: One of the biggest advantages of rotary drum granulation npk fertilizer production line is their excellent production capabilities. Compared with traditional disc granulation line, the production efficiency of drum granulation is significantly improved like doubled or trippled. Under standard production conditions, the output of the drum granulator can reach 48 tons per hour, while the disc granulator usually only has a production capacity of 5-10 tons per hour. Therefore, for large-scale fertilizer production enterprises, drum granulators can greatly increase output, shorten production cycles, and meet the growing market demand for fertilizers. For example, in terms of annual production capacity, a drum granulator can produce up to 600,000 tons of fertilizer per year, which is significantly higher than the output of traditional equipment. This enables fertilizer production companies to obtain higher economic benefits in a shorter period of time, thereby enhancing their market competitiveness.
• High-quality pellet forming and strength: The drum granulator has a unique advantage in the strength of pellet forming. Usually, the pellets after drying can reach 20 Newtons. Its design can produce pellets with high hardness and stability, which is crucial for the use and storage of fertilizers. High-hardness pellets can effectively prevent breakage or agglomeration during transportation and storage, ensuring the long-term use and quality of fertilizers. Specifically, the pellets produced by the drum granulator have excellent strength, usually reaching a compressive strength of 10-20N. This minimizes the damage rate of pellets during stacking, handling, packaging and other links. The stability of the pellets can also ensure the slow release of nutrients in the soil, ensuring that plants receive a balanced nutrient supply.
• Producing a variety of fertilizer varieties: The drum granulator is highly adaptable and can handle a variety of raw materials and different types of fertilizer formulations. This makes it particularly outstanding in the production of compound fertilizers. Whether it is nitrogen-phosphorus-potassium (NPK) compound fertilizers or organic and inorganic cow dung and chicken manure fertilizers, the drum granulator can efficiently granulate to meet different production requirements, but extrusion granulation and high tower granulation are more limited and can only produce specific varieties. In actual operation, the drum granulator can flexibly adjust the production process, such as changing the feed rate, steam volume or temperature control, to meet the needs of different fertilizers. Taking NPK compound fertilizers as an example, the drum granulator can easily handle different types of raw materials such as ammonium phosphate, urea, potassium chloride, etc., to ensure uniform mixing and efficient molding of fertilizers.
• Energy saving and reduced operating costs: The drum granulator has obvious advantages in energy saving. Compared with disc granulation and extrusion granulation, the drum granulator has higher energy efficiency and can consume less energy at the same output. Its optimized heat exchange system and fluid dynamic design can effectively reduce energy loss, thereby reducing overall energy consumption. The most important thing is that the output of drum granulation is large, so the unit cost and unit energy consumption are more advantageous. According to statistics, when using a drum granulator to produce fertilizers, compared with traditional equipment, the energy consumption per ton of fertilizer produced can be reduced by about 5%-15%. In addition, the maintenance cost of the drum granulator is also low, the equipment failure rate is low, and its structure is simple, which is easy to maintain and repair. These advantages effectively reduce the operating costs of enterprises and improve economic benefits.
• High degree of automation, reducing manual intervention: The drum granulation production line is equipped with an advanced PLC control system and an intelligent monitoring system, which can monitor key parameters such as temperature, humidity and particle size in the production process in real time. The automated system is able to adjust operating parameters based on real-time data, ensuring the stability of the production process and uniformity of pellet quality. In addition, the drum granulator relies less on labor during operation. It only needs three operators and two other employees for simple monitoring and maintenance. This allows companies to significantly reduce labor costs and improve production efficiency. Specifically, automated systems can reduce labor costs by approximately 30%-40% while improving production efficiency and product quality. The dosing system enables complete automation and remote recipe adjustment.

The best type of fertilization always requires the use of the best fertilizers. The best type of fertilizer for your plants depends on what you are trying to grow, and what types of soil you have. If you are growing vegetables in your garden you will want to choose a fertilizer that has high levels of nitrogen, phosphorus, and potassium.

Nitrogen helps produce green leaves and stems, phosphorus helps produce root development, and potassium helps the plant withstand stress from heat or cold.

A good all-purpose fertilizer would be a 10-10-10 NPK (nitrogen, phosphorus, and potassium). This type of fertilizer will work well for most plants and soil types.

If your soil is sandy or clay-based then you may want to use a fertilizer that has more phosphorus as well as a higher NPK value such as 15-15-15 since sandy soils don’t hold nutrients well and often need more nitrogen than clay-based soils do.

If you are growing flowers or fruit trees then it is best to use a slower release type of fertilizer such as an Osmocote slow-release granular fertilizer which works great when used in conjunction with organic mulches like straw or pine needles which provide some extra nutrients while also holding in moisture around the base of your plant.

There are many different types of fertilizer available and each one has its strengths and weaknesses. For instance, liquid fertilizers work quickly but are often expensive and can be hard to apply evenly. Pelleted fertilizers are easier to apply evenly but may take longer for the nutrients to become available for the plants.

Organic fertilizers like composted manures and alfalfa meals can be beneficial but they need time to break down to work well. Some organic liquid feedings are beneficial for plants that need a quick boost of nutrients but these don’t last very long either.

When deciding which type of fertilizer might be best for your garden, it’s important to consider what kind of plants you have and what their needs are at this stage in their lives. There are numerous methods for delivering nutrients to your plants. Many gardeners employ a variety of fertilizers and strategies in their gardens.

To address minor deficiencies or immediately stimulate development, try employing granular goods or manures to offer the key nutrients and water. Understanding what nutrients your plants require is crucial when choosing a fertilizer. Plants require nutrients to flourish, which they acquire through their root system from the soil.

Fertilizers feed plants with the major nutrients (nitrogen, phosphorus, and potassium, as well as crucial minor elements). The soil’s productive capability decreases with each harvest unless nutrients are supplemented.

Types of fertilizer

In general, there are two common types of fertilizers. They include organic and inorganic fertilizers.

1. Organic fertilizers

These are made from natural materials such as manure, compost, and peat moss. Organic fertilizers are generally easier on the environment, but they are slower acting than chemical fertilizers and they can cost more money. Some organic fertilizers have special properties that help to condition soil and improve its structure over time.

Organic fertilizers are derived from plant or animal sources. They provide nutrients for plants through decomposition. The most common organic fertilizer is composting material from an animal source (such as manure or composted chicken litter). This type of fertilizer helps retain moisture in the soil and adds essential nutrients to it.

It also provides a habitat for beneficial insects like earthworms that aerate the soil and improve its drainage capacity by bringing down deep-rooted plants from the topsoil layer to the subsoil layer where it can be accessed by the roots of most plants.

Organic fertilizers are generally considered more environmentally friendly than synthetic ones because they don’t pollute the soil or groundwater like chemicals might. However, all fertilizer can be harmful to your plants if used incorrectly — you have to know how much fertilizer to use as well as when and how to apply it.

2. Inorganic fertilizers

These are made from chemicals such as nitrogen (N), phosphorus (P), and potassium (K). These chemicals can be found in many different combinations to match the nutrient needs of specific plants. Inorganic fertilizers can be very effective, but some people worry about using them because they may run off into local water supplies or damage soil organisms like earthworms.

Inorganic fertilizers are often used when planting new plants or seeds in soil because they help plants get established quickly. This means that plants can produce more fruit and vegetables per plant than if they were growing in soil without any additional nutrients added to it.

For example, if you’re starting a garden from scratch, you may want to use chemical fertilizers until your plants are big enough to eat organic food waste. Inorganic fertilizers can also be used as a supplement for organic gardening methods. Inorganic fertilizers do not contain any organic matter and can be used on all plants.

They are easy to apply and may be water-soluble or granular. They are less likely than organic fertilizers to burn plant roots, which makes them suitable for delicate plants like seedlings and houseplants. They are less expensive than organic fertilizers.

Types of inorganic fertilizers

1. Nitrogen fertilizers

In Europe, nitrate-based fertilizers are the most widely used direct fertilizers. Nitrate-based fertilizers such as ammonium nitrate (AN) and calcium ammonium nitrate (CAN), which are well adapted to most European soils and climatic circumstances, and urea and urea ammonium nitrate (UAN) aqueous solutions, which are widely used in other areas of the world, are the primary products.

Ammonium sulfate and ammonium sulfate nitrate, calcium nitrate, sodium nitrate, Chilean nitrate, and anhydrous ammonia are some of the other straight nitrogen fertilizers. Nitrogen is an essential plant nutrient, but too much of it can lead to “nitrogen burn,” which causes leaf discoloration and even death.

To avoid this, use a fertilizer that’s high in nitrogen (N) only on actively growing plants (check labels) and at half their recommended dosage.

2. Nitrogen fertilizers with inhibitors

Nitrogen immobilization, denitrification, volatilization, and leaching can all occur as a result of certain climate conditions and soil properties, lowering fertilizer efficiency.

As a result, the fertilizer industry has created specialized fertilizers to mitigate these consequences. Foliar, delayed, and controlled release fertilizers, as well as fertilizer additives like urease and nitrification inhibitors, are among them.

3. Phosphorus fertilizers

Single superphosphate (SSP), triple superphosphate (TSP), monoammonium phosphate (MAP), di-ammonium phosphate (DSP), and ammonium polyphosphate liquid are the most prevalent phosphate fertilizers.

For efficient application, different fertilizer formulations have distinct release profiles and require different spreader settings. Phosphorus is also essential for healthy growth, but it doesn’t move beyond the root zone as easily as nitrogen does.

Because phosphorus needs to be applied more frequently than nitrogen, choose a slow-release product that will provide a steady supply of phosphorus throughout the season.

4. Potassium fertilizers

Potassium is also found in a variety of fertilizers, including potassium chloride (KCl), potassium sulfate (K2SO4) or sulfate of potash (SOP), and potassium nitrate (KNO3), often known as KN, which contain potassium alone or in combination with two or more minerals.

Potassium is a secondary element that helps plants resist disease and improve overall vigor. Look for potassium sources like potash sulfate or muriate of potash on product labels; they’re usually listed as K2O or KClO3.

5. Calcium, magnesium, and sulfur fertilizers

Secondary plant nutrients such as calcium (Ca), magnesium (Mg), and sulfur (S) are necessary. They are frequently used in conjunction with the major nutrients N, P, and K rather than as standalone fertilizers. Straight N fertilizers like ammonium nitrate or urea frequently contain sulfur.

Single superphosphate (SSP), potassium sulfate (SOP), and potassium magnesium sulfate (Kainite) are further sulfur sources, with the last also containing magnesium. Kieserite is a magnesium sulfate material that is mined and used in agriculture as a fertilizer, mostly to treat magnesium deficiency.

Calcium is mostly used in the form of calcium nitrate, gypsum (calcium sulfate), or lime/dolomite (calcium carbonate), with calcium nitrate being the only commonly available calcium source in plants.

6. Micronutrient fertilizers

The company is the world’s best npk 15-15-15 compound fertilizer supplier. We are your one-stop shop for all needs. Our staff are highly-specialized and will help you find the product you need.

Currently, a wide range of specialized fertilizers is readily accessible to provide plants with essential micronutrients including iron, manganese, boron, zinc, and copper. These might be inorganic or organic chemicals, with the latter being separated into water-soluble and non-soluble varieties.

7. Inhibitors

In today’s EU, there are two major types of inhibitors available to farmers. Nitrification inhibitors are chemical substances that restrict the activity of Nitrosomonas bacteria in the soil, delaying the nitrification of ammonium. The goal is to keep ammonium in a soil-stable state while slowing its conversion to nitrate.

This temporarily lowers the proportion of nitrate in the soil, lowering the risk of nitrate leaching into water or the generation of N2O gas in the atmosphere. Urease inhibitors are chemical substances that prevent the hydrolysis of urea in the soil, which can result in NH3 emissions, from occurring before it is transformed into ammonium.

They help to drastically reduce ammonia emissions into the atmosphere, which is one of the major air pollutants. For a better grasp of nutrients and their health benefits, here’s a spreadsheet:
