In the family of granulation equipment, the rotary drum granulator plays an important role in multiple industries such as fertilizers and chemicals due to its unique granulation characteristics, providing reliable guarantees for the production of high-quality granular products.

The primary characteristic of a rotary drum granulator is its excellent material mixing performance. During the continuous rotation of the drum, materials are fully rolled and scattered inside the cylinder. This enables various materials with different components to be evenly mixed together, whether it is the main elements such as nitrogen, phosphorus, and potassium in the base fertilizer, or the added trace elements and additives, they can be fully integrated under the stirring of the drum. This uniform mixing ensures the consistency of the ingredients in each product, thereby ensuring the stability of product quality, providing balanced nutrients for crops, or meeting the precision requirements of chemical products for ingredient accuracy.

The granulation process of this device is gentle and efficient. As the drum rotates, the material gradually aggregates into particles under the combined action of friction and centrifugal force. This process is relatively gentle and will not cause excessive damage to the physical and chemical properties of the material, especially suitable for materials that are sensitive to temperature and pressure. At the same time, the continuous rotation of the drum enables the granulation process to continue, resulting in high production efficiency and meeting the needs of large-scale production.

The particles produced by the rotary drum granulator have good roundness and strength. In the drum, materials constantly collide and rub against each other, making the particle surface smoother and the shape closer to a sphere. Moreover, by adjusting parameters such as the rotation speed of the drum, the humidity of the material, and the amount of binder used, the strength of the particles can be effectively controlled, making them easy to store and transport, while also releasing nutrients or performing their intended functions in a timely manner during use.

The rotary drum granulator also has strong adaptability. It can process various materials with different properties, whether they are powdered, granular or paste like raw materials, and can achieve granulation under appropriate conditions. Moreover, by changing the size, material, and internal structure of the drum, it can meet the diverse needs of different production scales and product requirements.

In addition, the structure of the rotary drum granulator is relatively simple, and it is easy to operate and maintain. Operators can easily control the operating parameters of the equipment, and the daily inspection, cleaning, and maintenance work of the equipment is also easy to carry out, which reduces the operating costs of the enterprise and improves the efficiency of equipment use.

The rotary drum granulator, with its excellent material mixing performance, mild and efficient granulation method, good particle quality, wide adaptability, and convenient operation and maintenance, has become an ideal choice for many enterprises in granulation production, promoting the steady development of related industries.

fertilizer granulator Mar 28, 2025

In the field of fertilizer processing, NPk fertilizer production lines are known for their stable quality, providing reliable fertilizer products for agricultural production.

Starting from the control of raw materials, the NPk fertilizer production line has established a strict quality inspection system. All raw materials containing nitrogen, phosphorus, and potassium entering the production line must undergo multiple testing processes to ensure their purity, nutrient content, and other indicators meet high standards. Only qualified raw materials can enter the production process, ensuring the quality of fertilizers from the source.

In the production process, advanced equipment and precise process control are the key to stable quality. High precision mixing equipment ensures that various raw materials are thoroughly and evenly mixed, so that the nitrogen, phosphorus, and potassium ratios in each fertilizer grain conform to the predetermined formula. For example, through strong stirring devices and special mixing chamber designs, even raw materials with different densities and flowability can achieve perfect fusion.

The granulation process also emphasizes quality. By adopting advanced granulation technology and equipment, the fertilizer particles produced have uniform size, regular shape, and moderate strength. The consistency of particle size ensures uniformity during fertilization, avoiding excessive or insufficient local nutrients; Appropriate strength ensures that particles are not easily broken during storage, transportation, and fertilization, reducing dust generation and improving the practicality of fertilizers.

The drying and screening processes have further improved the quality of fertilizers. Accurately control the drying temperature and time to achieve the appropriate moisture content of fertilizer particles, preventing clumping and mold growth. The screening equipment strictly screens out particles of qualified size, removing particles that are too large or too small, ensuring the uniformity of product specifications.

In addition, the NPk fertilizer production line is equipped with a comprehensive quality monitoring system. At various critical stages of production, real-time monitoring of various indicators of fertilizers is carried out. Once quality issues are identified, measures can be quickly taken to adjust and correct them.

Stable quality NPk fertilizer makes farmers feel more at ease when using it. Whether it is long-term cooperative old customers or new trial users, they can have confidence in product quality.

The granulation process and equipment of NPK fertilizer production line

fertilizer granulator Mar 28, 2025

Granulation is one of the core processes of NPK fertilizer production line, which determines the quality and performance of fertilizer particles.

When the evenly mixed raw materials enter the fertilizer granulator, the granulation process officially begins. There are various common methods for NPK fertilizer granulation, among which rotary drum granulation is widely used. In the rotary drum granulator, the raw materials continuously roll in the rotating drum. At the same time, an appropriate amount of adhesive is sprayed into the drum through the nozzle, which acts as a bridge to gradually aggregate the loose raw materials into particles.

Disc granulation is also a common method. The disc granulator rotates at a certain speed, and the raw materials are added from above. Under the centrifugal and frictional forces of the disc, they roll along the inner wall of the disc. As the rolling process progresses, the raw material continuously adsorbs surrounding materials and gradually grows into particles. This method produces particles with regular shapes and high roundness.

Squeezing granulation is the use of a roller squeezing granulator. The mixed material is fed between two relatively rotating rollers, and under strong extrusion pressure, the material is squeezed into thin sheets. Then, through subsequent processes such as crushing and screening, the desired particle size is formed. The particle density and strength produced by extrusion granulation are relatively high.

During the granulation process, parameters such as temperature, humidity, and rotational speed have a significant impact on particle quality. For example, an appropriate temperature helps the adhesive to function better and promote particle formation; If the humidity is too high, particles are prone to adhere, while if the humidity is too low, it is not conducive to aggregation. Both too fast and too slow rotation speed can affect the size and uniformity of particles.

After granulation is completed, the newly formed particles are still relatively fragile and require a certain amount of time for solidification. The solidification process can enhance the internal bonding force of particles and improve their strength. After solidification, the particles are ready to enter the subsequent drying, screening and other processes, and move towards the final qualified NPK fertilizer product.

In terms of energy conservation, the NPk fertilizer production line uses high-efficiency and energy-saving equipment. For example, the motor adopts energy-saving products with high power factor, which can reduce energy consumption. The dryer adopts advanced heat exchange technology, which improves energy utilization efficiency and reduces the loss of heat energy while ensuring the drying effect.

The intelligent control system of the production line also contributes to energy conservation. By monitoring and regulating the operating parameters of the equipment in real-time, the power and operating speed of the equipment are automatically adjusted according to production needs, avoiding equipment idling and excessive energy consumption.

In addition, the fertilizers produced by the NPk fertilizer production line also have the characteristics of environmental protection and energy conservation. Accurately proportioned fertilizers improve nutrient utilization efficiency and reduce nutrient loss and environmental pollution caused by excessive fertilizer application. The application of slow-release fertilizers further reduces the frequency of fertilization and minimizes the potential harm of fertilizers to soil and water bodies.

The NPk fertilizer production line integrates the concept of environmental protection and energy conservation throughout the entire production process, not only reducing production costs for enterprises, but also making positive contributions to environmental protection.

Coating and packaging process of NPK fertilizer production line

fertilizer granulator Mar 28, 2025

In the NPK fertilizer production line, coating and packaging are the final key processes that directly affect the market image and usage effect of the product.

After drying and screening, qualified fertilizer particles first enter the coating process. The main purpose of encapsulation is to form a protective film on the surface of particles, preventing them from absorbing moisture and clumping during storage and transportation, while also delaying the release rate of fertilizer nutrients and improving fertilizer utilization efficiency.

Common coating materials include paraffin, resin, etc. In the coating device, fertilizer particles are evenly sprayed with coating material. By precisely controlling the spraying amount and coating time, ensure that each fertilizer receives a suitable thickness of coating. During the coating process, attention should be paid to parameters such as temperature and stirring speed to ensure that the coating material adheres uniformly to the surface of the particles.

After the NPK fertilizer production line completes the coating, the fertilizer particles can be packaged. The packaging process begins with measurement, using automatic measuring equipment to pack fertilizers into packaging bags according to the specified weight. The measurement accuracy requirement is very high to ensure that the weight of each bag of fertilizer is accurate and meets market sales standards.

Packaging bags are generally made of plastic woven bags or composite bags, which have good moisture-proof and insect proof properties. The bagged fertilizer is sealed by a sealing machine to ensure that the packaging bag is tight and leak free.

On the packaging, important information such as the product name, ingredients, nutrient content, production date, and shelf life will be clearly labeled. These labels are not only convenient for consumers to understand the product, but also an important basis for product quality traceability.

Some high-end NPK fertilizer products also have a layer of exquisite paper boxes wrapped around the packaging to enhance the product’s grade and market competitiveness.

After being coated and packaged, NPK fertilizers are neatly stacked in warehouses, waiting to be transported to agricultural markets across the country, providing strong nutrient support for agricultural production and completing the mission journey from NPK fertilizer production lines to fields.

The granulation characteristics of the disc granulator play an important role in fertilizer production

fertilizer granulator Mar 28, 2025

In the field of granulation equipment, the disc granulator occupies an important position in many production scenarios due to its distinct and unique granulation characteristics, and is highly favored by industries such as fertilizers and chemicals.

One of the core features of the disc granulator is its precise particle size control ability. The disc rotates uniformly under the drive of the motor, and the material continuously rolls inside the disc. By adjusting parameters such as the rotation speed, inclination angle, and material addition amount of the disc, the growth process of particles can be precisely controlled, resulting in uniform and consistent particle size in the produced particles. This precise control is crucial for many industries with strict particle size requirements, such as the fertilizer industry. Uniform particle size fertilizer particles can ensure consistent nutrient release, which is beneficial for crops to absorb nutrients in a balanced manner and achieve increased production and income.

The granulation rate of this device is quite high. During the rotation of the disc, materials collide and aggregate with each other, rapidly forming particles under the action of the binder. Due to the regular movement trajectory of materials inside the disc, most of the materials can participate in the granulation process, reducing the generation of fine powder and waste, improving the utilization rate of raw materials, and reducing production costs.

The particles produced by the disc granulator have good physical properties. The particle shape is approximately spherical with a smooth surface, which makes it less prone to clumping and scattering during storage and transportation. Moreover, the flowability of spherical particles is good, which facilitates subsequent packaging, measurement, and application. Whether it is manual operation or mechanized operation, it can be carried out more smoothly.

The disc granulator has strong adaptability to raw materials. Whether it is various chemical fertilizer raw materials or intermediates of some chemical products, as long as they have a certain viscosity or can achieve agglomeration after adding binders, they can be granulated in a disc granulator. This wide adaptability of raw materials enables enterprises to flexibly choose raw materials in the production process and reduce procurement costs.

In addition, the disc granulator has a simple structure and is very easy to operate and maintain. The overall structure of the equipment is compact, occupying a small area, and easy to install and debug. Operators can proficiently master the operation of equipment through simple training. Daily maintenance work is relatively easy, with regular checks on the wear and tear of the disc, cleaning of material residues, etc. This greatly reduces equipment downtime and improves production efficiency.

The disc granulator, with its precise particle size control, high granulation rate, good physical properties of particles, wide adaptability to raw materials, and convenient operation and maintenance, has become a powerful equipment for many enterprises to achieve efficient and high-quality granulation production, effectively promoting the development of related industries.

The diversity of NPk fertilizer production lines meets the diversified needs of agriculture

fertilizer granulator Mar 28, 2025

One prominent feature and advantage of the NPk fertilizer production line is its ability to produce a diverse range of fertilizer products, meeting the diversified needs of modern agriculture.

Firstly, in terms of formula diversity, this production line can mix various proportions of NPk fertilizers according to the growth characteristics and nutritional needs of different crops. For leafy vegetables, emphasis is placed on the supply of nitrogen elements, producing high nitrogen NPk fertilizers to promote the lush growth of leaves; For melon and fruit crops, emphasis is placed on increasing the content of phosphorus and potassium elements during the flowering and fruiting periods, producing flower promoting and fruit preserving fertilizers, and improving the quality and yield of fruits. Fertilizer formulas can also be customized for different soil conditions to improve acidic or alkaline soils and enhance soil fertility.

Secondly, the NPk fertilizer production line is capable of producing fertilizer products in different forms. In addition to common granular fertilizers, water-soluble fertilizers can also be produced. Water soluble fertilizers have the characteristics of good solubility and fast absorption, making them particularly suitable for modern irrigation systems such as drip irrigation and sprinkler irrigation, achieving water fertilizer integration, improving fertilizer utilization efficiency, and saving water resources. In addition, slow-release fertilizers can be produced, which can slowly release nutrients according to the growth rhythm of crops, reduce the frequency of fertilization, lower fertilizer loss, and protect the environment.

Furthermore, the production line can add various functional ingredients to fertilizers, further enriching the variety of products. For example, adding trace elements such as boron, zinc, and iron to meet the crop’s demand for trace elements and prevent nutrient deficiencies; Adding organic components such as humic acid and amino acids to improve soil structure, enhance soil water and fertilizer retention capacity, and improve the quality of agricultural products.

Drying and screening process of NPK fertilizer production line

fertilizer granulator Mar 28, 2025

Drying and screening are indispensable links in the NPK fertilizer production line, playing a key role in ensuring the quality of fertilizer products.

The fertilizer granules after granulation contain a certain amount of moisture. If not removed in time, they are not only prone to clumping, but also affect the storage period and effectiveness of the fertilizer. Therefore, the particles first enter the drying process.

Drying equipment usually uses fertilizer dryers, commonly including drum dryers. The particles slowly move forward in the dryer as the drum rotates, while high-temperature hot air is blown in from the other end. Hot air comes into full contact with particles and carries away the moisture in the particles through heat transfer. During the drying process, it is necessary to strictly control the temperature and residence time. Excessive temperature may lead to the decomposition of certain components in fertilizers, affecting nutrient content; If the residence time is insufficient, the ideal drying effect cannot be achieved.

After drying, the moisture content of the particles is significantly reduced and reaches the appropriate standard before entering the screening stage. The purpose of screening is to classify particles according to their size, ensuring that the particle size of the product is uniform and consistent.

Fertilizer vibrating screen is the main equipment in the screening process. It causes particles to bounce on the sieve through high-frequency vibration. Particles smaller than the mesh size fall through the sieve and become fine powder; Particles larger than the mesh size remain on the sieve and continue to move forward. Particles within the qualified particle size range are collected and enter the next process.

The processing methods for unqualified particles screened out are different. Oversized particles usually enter the fertilizer crusher for crushing, and the crushed material participates in the granulation process again; Small fine powder is usually returned to the mixing process and mixed and granulated again with new raw materials.

The drying and screening processes are closely coordinated, with drying providing a suitable material state for screening, and the screening process further ensuring the quality and uniform specifications of fertilizer particles. After these two processes, the NPK fertilizer particles are one step closer to becoming the final qualified product.
