3. Extend the service life of the equipment: Regular maintenance and inspection are important measures to extend the service life of organic fertilizer equipment. Including checking the wear of key components, maintenance of the lubrication system, and detection of the electrical system.

4. Improve product quality: Standardized operation helps to improve product quality. For example, by controlling the particle size and moisture of the material, ensure that the material meets the equipment requirements and avoid the decline in the quality of particle molding due to material problems.

5. Reduce production costs: Standardized operation can reduce production costs. For example, by reasonably adjusting equipment parameters, avoid overloading of equipment, reduce energy consumption and equipment loss. At the same time, regular maintenance of equipment can reduce equipment failures and maintenance costs.

Through standardized operation, the production efficiency, product quality and equipment life of the double roller press granulator can be effectively improved, while reducing production costs and safety risks. Therefore, standardized operation is crucial to the operation of the double roller press granulator.

How to scientifically maintain the double roller press granulator

As an important organic fertilizer production equipment, the double roller press granulator can always maintain efficient operation, extend its service life, and escort production. Mastering scientific maintenance methods can not only reduce the hidden dangers of failure, but also enable the equipment to output high-quality particles stably for a long time.

Daily maintenance needs to form a standardized process. Before starting the machine, in addition to checking the connection and fasteners of the components, it is necessary to focus on whether the feed port is unobstructed, remove possible foreign matter, and avoid material jamming and damage to the equipment after starting. During operation, in addition to paying attention to the rotation and sound of the rollers, it is also necessary to observe the temperature of the motor. If overheating occurs, the machine should be shut down to cool down to prevent the motor from burning. The cleaning work after shutdown should be thorough. A special brush can be used to clean the residual material in the roller texture, and compressed air can be used to blow the equipment gap to prevent the material from corroding the components after moisture and agglomeration.

Maintenance of key components must be accurate and in place. The parallelism of the rollers needs to be checked every time they run for a period of time. If there is an offset, it should be calibrated in time to ensure uniform extrusion force; when the surface is worn to a certain extent, it can be polished and repaired to extend the service life. Bearing lubrication requires the use of lubricating oil of suitable types, which should be refilled at least once a month. Before refilling, clean the impurities in the oil filling port to prevent contamination of the lubrication system. The chain of the transmission system should be regularly smeared with chain oil, and the gears should be checked for meshing. If abnormal noise or jamming is found, timely adjustments should be made to avoid affecting the granulation efficiency due to poor power transmission.

Well-maintained equipment can reduce downtime, maintain stable granulation efficiency and granule quality, and reduce long-term use costs. Choose a double roller press granulator and cooperate with scientific maintenance to make your organic fertilizer production line continue to be efficient and your profits more guaranteed.

Disc Granulator Maintenance: Keeping Your Machine Young

A well-maintained disc granulator, like a regularly serviced sports car, maintains peak performance while significantly extending service life. Master these simple yet crucial maintenance techniques, and your equipment will reward you with longer service time and more stable product quality.

A well-maintained disc granulator, as a core component of an NPK fertilizer granulator machine, ensures efficient granulation in both the NPK manufacturing and production processes. Just as proper upkeep enhances equipment longevity and performance, optimized granulator operation directly impacts the quality and consistency of NPK fertilizers. The terms “NPK manufacturing process” and “NPK production process” are often used interchangeably, with the disc granulator playing a vital role in the granulation stage of these processes.

1. Daily Check: The “Morning Routine”

Before starting up each day, spend 5 minutes on a comprehensive “physical exam”: gently shake components to check tightness, listen for clear operating sounds from the transmission, and inspect the disc surface for abnormal wear. These small actions help identify potential issues early, preventing minor problems from becoming major failures.

2. Lubrication: The “Circulatory System”

Regularly replenishing specialized lubricant for bearings and gears is as important as nutrition for athletes. Always use the lubricant type recommended in the manual and strictly control the amount – too little causes insufficient lubrication, too much may lead to leaks. Maintain a lubrication record to ensure every maintenance is accurate.

⚠️ Special reminder: Different parts may have different lubrication intervals. For example, high-speed bearings may need weekly lubrication while low-speed gears may only need monthly lubrication.

3. Cleaning Habits: Details Make the Difference

Clean the disc granulator machine immediately after each production run before materials completely harden. Use specialized scrapers and compressed air, paying special attention to nozzle and liner seams. Regular surface dusting may seem simple but prevents 90% of unexpected failures.

4. Wear Parts Management: Prepare for Rainy Days

Maintain replacement records for wear parts like liners and bearings. When nozzle atomization becomes uneven or liner thickness wears beyond 10%, consider replacement even if still functional. Keep commonly used wear parts in stock to avoid production losses waiting for replacements.

5. Safe Operation: The Uncrossable Line

Adjustments are strictly prohibited during operation! All maintenance must follow the “shutdown-power-off-tagout” procedure. Please post safety operating procedures near the control panel and conduct regular safety training to strengthen everyone’s safety awareness.

Remember: Preventive maintenance typically costs only 1/10 of repair after failure. Invest small amounts of time in these routine maintenance tasks, and your disc granulator will create greater value for you.

How to improve the granulation rate of the disc granulator

The granulation rate of the disc granulator directly affects the production efficiency and quality of organic fertilizer. When processing organic fertilizer raw materials containing high fiber and impurities, the disc granulator can take the following measures to ensure the uniformity and granulation rate of the particles:

Pretreatment of raw materials: For raw materials with high fiber and many impurities, it is necessary to first remove large impurities and long fibers through crushing and screening to make the material texture more uniform, provide high-quality basic materials for granulation, and reduce granulation failure caused by uneven raw materials.

Adjust the disc parameters: According to the characteristics of the material, reasonably adjust the disc inclination angle and speed. If the angle is too small, the material is easy to accumulate; if the angle is too large, the material residence time is short. Too fast speed will cause the material to be thrown out due to excessive centrifugal force, and too slow speed will make it difficult to fully roll and agglomerate. By repeatedly debugging and finding the appropriate parameters, the material can form a stable rolling track in the disc and promote uniform growth of particles.

Adding binder: By increasing the spraying amount and uniformity of the binder, the bonding of the material can be improved, thereby improving the strength and uniformity of the particles.

Install screening device: Install drum screener machine in the fertilizer production line to separate unqualified particles and impurities in time, return them to the granulator for reprocessing, form a closed loop, reduce the waste of raw materials, and ensure the uniformity of the output particles.

Clean the equipment regularly: Clean the disc and the inside of the disc granulator regularly to prevent the accumulation of impurities from affecting the granulation effect.

Through these methods, the disc granulator can stably maintain a high granulation rate, improve the quality and efficiency of organic fertilizer production, and help produce high-quality granular fertilizer.

The unique working principle of the double roller press granulator

The reason why the double roller press granulator can occupy an important position in the organic fertilizer granulation equipment is inseparable from its unique working principle, which also allows it to show many advantages.  Its working process is clear and straightforward. First, the pre-treated dry powder raw material is conveyed between two relatively rotating rollers. The surface of this pair of rollers is usually provided with specific lines or grooves. Under the action of strong extrusion force, the raw material is tightly squeezed to form continuous flakes. These flakes then enter the crushing device and are crushed into particles of different sizes. Next, the particles will go through the screening stage, and the fine powder or large particles that do not meet the requirements will be separated and sent back to the granulation system, while the qualified particles will become the final product.

This working principle brings significant advantages. There is no need to add a lot of water, and the subsequent drying step is omitted, which not only saves energy, but also maintains the original nutritional content of the raw materials. The whole process is coherent and efficient, from the entry of raw materials to the output of qualified particles, which can be completed in one go and quickly meet production needs. At the same time, due to the physical extrusion granulation, it has strong adaptability to raw materials, and a variety of organic raw materials can be made into granules in this way.

The double roller press granulator has become an efficient and practical granulation choice in the organic fertilizer production line due to its scientific working principle, helping producers improve efficiency and ensure quality.

The Silent Revolution in Your Soil: Bio-Organic Fertilizers Explained

In modern fertilizer plants, you’ll find two seemingly similar yet fundamentally different production lines: the traditional organic fertilizer line and the bio-organic fertilizer line. Both process organic waste, but the latter features an invisible “magician” – microbial communities.

Microbes: The Invisible Engineers

While traditional organic fertilizer relies on physical composting, bio-organic production is essentially a precision microbial cultivation experiment. Specialized fermentation tanks serve as five-star hotels for microorganisms, with PLC systems meticulously controlling temperature, humidity, and oxygen levels to create optimal working conditions for these tiny life forms to break down organic matter into more absorbable forms.

Core components of bio-organic lines:

• Intelligent fermentation systems – “Incubators” for microbes

• Microbial inoculant dispensers – Precision “microbe seeders”

• Gas chromatographs – Continuous metabolite monitoring

Beyond Fertilizer: Soil Physicians

Traditional lines produce “plant food,” while bio-organic lines deliver “soil therapy.” Those carefully selected microbial strains function like microscopic medical teams, continuing their work after entering the soil: some fix nitrogen, others solubilize phosphorus, while others suppress pathogens… This is ecological magic traditional lines cannot replicate.

Next time you see fertilizer labeled “bio-organic,” remember: this bag contains not just nutrients, but an entire micro-ecosystem ready to awaken sleeping earth.

How to choose a suitable fertilizer granulator?

In the field of fertilizer production, it is very important to choose the right granulator, which directly affects product quality, production efficiency and corporate benefits. Faced with a wide range of fertilizer granulators, how to choose?

Raw material characteristics are the primary consideration. For processing high-humidity materials such as livestock and poultry manure, the rotary drum granulator can meet the needs; fiber raw materials such as straw have high hardness, and the high-pressure molding technology of the double roller press granulator can ensure the compactness of the particles.

The scale of production needs to be considered. Large production lines have a large daily output demand, and the rotary drum granulator has become the first choice due to its continuous operation ability. It can be adapted to 10,000-ton organic fertilizer projects to meet high-intensity production. Medium-sized enterprises can choose a disc granulator, which can balance efficiency and cost and is suitable for the production of 10-20 tons of compound fertilizer per day. For small workshops or laboratories, the flat die granulator is flexible to operate, occupies a small area, and can easily cope with small batch production.

The requirements for particle quality also affect the choice of granulators. If spherical particles with a high ball formation rate are required, the disc granulator is an ideal choice. The organic fertilizer particles it produces are round and have good commercial properties. For high-strength columnar particles, the double roller press granulator has a good molding effect, high particle hardness, and is not easy to break. The ring die granulator can flexibly switch molds and produce particles of different shapes and sizes to meet diverse needs.

From the perspective of process and economy, in the dry production process, the double roller press granulator does not need to add water, reduces the drying process, and reduces energy consumption. In wet production, the rotary drum granulator and the drying equipment work well together, which is suitable for large-scale continuous production. From the perspective of maintenance cost, the flat die granulator has fewer wearing parts and is easy to repair; although the hydraulic roller granulator has a higher initial investment, it is durable and has a lower long-term use cost.

Considering the above factors comprehensively, select the appropriate one from many models to make fertilizer production more efficient and higher quality.. 

How to choose between a rotary drum granulator and a disc granulator?

In the fertilizer, feed and other industries, disc granulators and rotary drum granulators are both common granulation equipment, playing a key role in fertilizer production lines. Understanding their differences can help companies choose the right equipment and achieve efficient production.  From the working principle, when the disc granulator tilts the disc and rotates, the material continues to roll and agglomerate under the action of gravity, centrifugal force and friction. First, small particles are formed at the bottom of the disc, and then they continue to roll, absorbing the surrounding powder and gradually become larger. After reaching a certain size, they overflow from the edge of the disc to complete the granulation. The material of the rotary drum granulator rolls continuously in the rotating drum, and through water or steam, the basic fertilizer and other materials are fully reacted chemically in a wet environment, and the particles are agglomerated into balls under the extrusion force generated by the rotation of the cylinder.

In terms of equipment structure, the disc granulator is relatively simple. The core component is the tilted granulation disc, which is driven to rotate by the drive device. There are also disc inclination adjustment mechanisms, racks, feeding pipes, liquid sprayers, hanging plates, etc. The rotary drum granulator has a complex structure. The main body is a huge rotating cylinder, which is driven by a drive device. In addition, there are feeding systems, steam or gas supply systems, discharging systems, and complex control systems and auxiliary equipment such as temperature and humidity sensors. ​

The two have different focuses in their application areas. The disc granulator has a small investment and is easy to operate. It is a powerful assistant for small production plants and is widely used in small compound fertilizer plants, feed processing plants and small biomass fuel enterprises. The rotary drum granulator is like an industrial giant with high output and is suitable for large-scale production. It performs well in large-scale compound fertilizer and feed production enterprises and industrial raw material granulation processing. ​​

Disc granulators and rotary drum granulators have their own advantages and disadvantages. Enterprises must make comprehensive considerations and careful choices based on their own production scale, material characteristics, product quality requirements and budgets to win development opportunities in the fierce market competition.
