Professional fertilizer machine manufacturers continuously innovate, developing various granulation equipment including flat die pellet machines and fertilizer compaction machines. Among these, fertilizer granules compaction technology directly compresses powder raw materials into shape under high pressure, not only improving production efficiency but also ensuring precise nutrient formulation and controlled release.

The Perfect Fusion of Organic and Inorganic

In the context of sustainable agriculture, bio organic fertilizer production is experiencing unprecedented development opportunities. Modern organic fertilizer manufacturing machines skillfully combine traditional organic materials with contemporary production processes, preserving the natural advantages of organic fertilizers while achieving the precision of chemical fertilizers.

Through innovative NPK fertilizer production technology, producers can customize the most suitable fertilizer formulations according to crop needs and soil conditions. This concept of precision fertilization not only improves fertilizer utilization efficiency but also reduces environmental impact, truly achieving sustainable agricultural development.

Choosing the Right Fertilizer Production Solution

Whether it is a large NPK production line or a small organic fertilizer equipment, choosing the right production equipment is crucial. Experienced fertilizer machinery manufacturers can provide complete solutions from fertilizer compaction to rotary granulation to ensure that each production link achieves optimal performance.

With the continuous advancement of NPK production technology, intelligence and automation are becoming new industry standards. From raw material formulation to finished product packaging, every link embodies the wisdom of scientific and technological innovation, providing solid protection for global food security.

Bio-organic fertilizer equipment: A key link to unlocking green fertilizer production

With the growing adoption of green agricultural development, market demand for bio-organic fertilizer continues to rise due to its ability to improve soil quality and crop quality. Bio-organic fertilizer equipment has become the core link between raw materials and qualified products, directly determining production efficiency and quality.

In the bio-organic fertilizer production process, equipment plays a crucial role throughout. During the raw material pretreatment stage, crushing and mixing equipment refines and evenly distributes raw materials like livestock manure and straw, laying the foundation for subsequent fermentation. The fermentation stage is crucial. Specialized fermentation equipment can maintain a stable fermentation temperature within a range suitable for microbial activity through temperature, humidity, and ventilation control. This not only shortens the fermentation cycle but also effectively eliminates insect eggs and pathogens in the raw materials, reducing the risk of farmland diseases.

Subsequent granulation, drying, and screening equipment determine the product’s form and purity. Granulation equipment can convert loose fermentation materials into granules, facilitating storage and transportation while minimizing nutrient loss. Drying equipment can control the product’s moisture content to below 15%, preventing clumping and mold. Screening equipment can remove impurities and ensure uniformity of organic fertilizer particles.

In addition, high-quality bio-organic fertilizer equipment incorporates environmentally friendly features, such as deodorization and dust removal devices, to reduce exhaust and dust emissions during production, helping companies achieve green production.

Key points for daily maintenance of BB fertilizer mixers to extend equipment life

As a long-term operating equipment in fertilizer production, BB fertilizer mixers require scientific daily maintenance to effectively reduce downtime, extend their service life, and ensure stable production. Maintenance should focus on the core components of the BB fertilizer mixer, with the mixing mechanism being the key. Regularly inspect the agitator shaft and blades for wear. Deformed or damaged blades should be replaced promptly to prevent poor mixing performance. Regular lubrication of the agitator shaft bearings is also crucial to reduce friction and minimize the risk of damage.

Maintenance of the drive system, including the motor and reducer, is also crucial. Regularly monitor the motor’s temperature and noise during operation. Any abnormal heating or noise should be promptly investigated to prevent motor burnout. Reducer lubrication should be regularly replaced to ensure transmission efficiency and avoid excessive wear due to insufficient lubrication.

Maintenance of the feed and discharge systems is equally critical. After each run, check the feed and discharge ports for residual material blockages and clean them promptly to ensure smooth material flow. Also, check the seal of the discharge valve to prevent material leakage that could cause waste or pollute the production environment.

In addition, after each production, the inside of the mixing drum needs to be thoroughly cleaned to avoid residual raw materials from clumping and to prevent contamination of new raw materials during the next production. With the help of the easy-to-clean design features of the BB fertilizer mixer, the cleaning work can be completed efficiently.

How does a disc granulator create round, uniform fertilizer granules?

The roundness and uniformity of fertilizer granules directly impact the ease of application (spreading uniformity) and product competitiveness. Disc granulators, with their unique “rolling forming” principle, are key equipment for producing high-quality granules. The key lies in precisely controlling parameters to achieve the ideal shaping process within the disc.

Disc granulators do not rely on extrusion to form granules, but instead continuously roll the raw materials within a rotating disc. Initially small granules continuously absorb surrounding powder, gradually growing larger like a “snowball.” During this process, the granules rub against each other, naturally forming a rounded appearance. These granules are particularly suitable for products with high requirements for granule shape, such as organic fertilizers and biological fertilizers.

Pellet quality is determined by several parameters. The first is the disc’s inclination angle. A small angle prolongs the material’s residence time within the disc, resulting in larger particles. A large angle causes the particles to overflow quickly, resulting in smaller particles. The second is the disc’s rotational speed. Low speeds are suitable for low-viscosity raw materials, preventing powder splashing; high speeds are suitable for sticky raw materials like organic fertilizer, enhancing the rolling adsorption effect. The third is the feed rate. Maintaining a uniform feed rate prevents excessive feed from causing particle accumulation and deformation, while insufficient feed leads to uneven particle size.

Furthermore, for fertilizers such as biofertilizers that require the preservation of bacterial inoculants, disc granulators eliminate the need for high-temperature extrusion. The forming process temperature is kept below 40°C, ensuring the survival of the inoculant. The resulting rounded particles are easy to package and transport, ensuring both functionality and commercial appeal.

Double screws compost turning machine routine maintenance extends equipment life

Double screws compost turning machines are high-frequency equipment for organic fertilizer fermentation. Proper routine maintenance directly impacts their service life and operational stability.

1.Precise Maintenance of Spiral Blades

After each operation, clean any sticky material from the blades (a high-pressure water jet can be used to prevent wear and tear from hardening). Check the blade fastening bolts weekly and tighten any loose bolts immediately to prevent vibration and increased wear. Derust the blades and apply a wear-resistant coating quarterly to extend double screws compost turning machine’s service life.

2.Transmission and Travel System Maintenance

Check the lubricating oil level in the motor and reducer monthly and add specialized lubricant to prevent wear and tear on gears and bearings due to lack of oil. Regularly clean debris from the travel tracks and crawler tracks to prevent jamming. If the double screws compost turning machine deviates, adjust the track parallelism or crawler track tension promptly to ensure smooth movement.

3.Electrical System Safety

Fermentation workshops are characterized by high humidity. Regularly check the seals of motors and control cabinets to prevent moisture-induced short circuits. Clean dust from electrical components, check for loose connections, and tighten terminal blocks. Perform a no-load test run monthly to test the operating status of motors and inverters. Detect and address any anomalies promptly to avoid prolonged downtime caused by electrical failures.

Why are double screws compost turning machines the preferred choice for large-scale organic fertilizer production?

The fermentation process of large-scale organic fertilizer production (processing over 500 tons of raw materials daily) faces the challenges of high processing volume, tight fermentation cycles, and high labor costs. The double screws compost turning machine’s design features perfectly meet these requirements, making it a core piece of equipment for large-scale production.

1.Efficient and Continuous Operation

The double screws compost turning machine continuously moves along the fermentation tank, turning the compost without frequent downtime and adjustments. A single unit can process up to 100-200 tons per hour, meeting the continuous fermentation needs of large-scale production lines and ensuring timely composting.

2.Stable and Uniform Compost Turning Quality

Large-scale production requires high consistency in fertilizer quality. The double screws compost turning machine’s two spirals work in tandem, ensuring uniform mixing of the material, both vertically and horizontally, and ensuring even oxygen exposure. Fertilization temperature fluctuations are controlled within ±3°C, preventing uneven fermentation and causing uneven fertilizer quality.

3.Significantly Reduced Labor Costs

Traditional manual compost turning can only process 5-10 tons of material per person per day. A single double screws compost turning machine can replace 20-30 workers. The machine operates without human intervention (it supports automatic movement and compost turning), eliminating the efficiency fluctuations associated with manual operation.

How does a large wheel compost turner adapt to large-scale organic fertilizer production lines?

With the large-scale development of the organic fertilizer industry, production lines are placing increasingly stringent demands on equipment adaptability. With its exceptional integration capabilities, large wheel compost turners have become core equipment for large-scale organic fertilizer production lines.

Within the production line process, they seamlessly connect pre-treatment and processing. During pre-treatment, raw materials such as livestock and poultry manure processed by a solid-liquid separator and pulverized straw from a pulverizer are piled into windrows 5-8 meters wide and 1.5-2 meters high. The large wheel compost turner slowly moves along the windrows, turning and fermenting the material. The fermented material is then conveyed by conveyor to equipment such as granulators, screens, and dryers, forming a complete production chain from pre-treatment to fermentation, enabling continuous production.

For large-scale production lines with an annual output of over 100,000 tons, the equipment rotates through multiple windrows: one receiving fresh raw material, one performing high-temperature fermentation, and one completing cool-down composting. This fixed cycle allows for a daily processing capacity of 800-1,500 tons, meeting the needs of large-scale production.

In addition, its electronic control system flexibly adjusts the turning and travel speeds, adjusting the fermentation progress based on the raw material supply and pelletizing capacity, ensuring a stable production line. Furthermore, compared to tank fermentation, it improves site utilization by over 30%, saving valuable land resources for large-scale production lines.

Double screws compost turning machine: The “Core of Efficient Turning” for organic fertilizer fermentation

In organic fertilizer production, the quality of compost turning during the fermentation process directly determines fertilizer maturity and nutrient retention. The double screws compost turning machine, with its unique structural design, is a key device for addressing uneven compost turning and slow fermentation. Its dual helical operation ensures sufficient oxygen and uniform heat dissipation within the fermentation tank, significantly improving fermentation efficiency.

The core working components of the double screws compost turning machine are two sets of parallel spiral blades. As the device moves along the fermentation tank track, the blades rotate clockwise, tossing the bottom material upward while simultaneously dispersing it to the sides. This turning method creates a “rolling up and down, mixing left and right” motion pattern for the material.

During the fermentation process, turning the compost not only provides sufficient oxygen for microorganisms but also quickly dissipates heat generated by the fermentation process, preventing nutrient loss due to localized high temperatures. For different raw materials such as livestock and poultry manure, straw, etc., the spiral speed and double screws compost turning machine movement speed can be adjusted to control the turning depth (up to 1.5-3m) and frequency, ensuring that the materials are fully composted within 7-15 days. Compared with manual turning, the efficiency is increased by more than 10 times.

new type of stirring tooth organic fertilizer granulator: The Magician of Fertilizer Production

On the stage of modern agriculture, the new type stirring tooth organic fertilizer granulator performs like a master craftsman, transforming powdery raw materials into uniform, spherical fertilizer pellets. The new type of stirring tooth organic fertilizer granulator is also called “new type of two-in-one organic fertilizer granulator“, a title reflecting its dual-function efficiency. While alternatives like the disc granulator anchor a conventional disc granulation production line, this advanced fertilizer granulator offers remarkable versatility. It serves as a core component not just in a dedicated organic fertilizer production line, but can also be integrated into a standard npk fertilizer production line or a complete npk fertilizer line. This seemingly simple machine contains exquisite engineering design, with each component carefully calculated to complete the “raw material metamorphosis” with high efficiency and consistent quality, making it a valuable asset across different fertilizer manufacturing systems.

1. The “Internal Organs” of Granulator

An efficient new type of stirring tooth organic fertilizer granulator is like a precision Swiss watch, with each part performing its own role:

Feeding System – Like the machine’s “mouth,” composed of a hopper and screw feeder. This “smart oral cavity” can precisely control “food intake” according to production needs, ensuring materials enter the granulation cylinder evenly and steadily.

The granulation cylinder is the machine’s “stomach,” made of stainless steel with diameters ranging from 0.5-2 meters and lengths of 1-3 meters. Its smooth inner wall is like a non-stick coating, preventing material adhesion and making the granulation process smoother.

The stirring teeth are the machine’s “teeth,” with 4-8 high-strength alloy steel stirring teeth arranged symmetrically, rotating at 300-1000 rpm, mixing and kneading materials thoroughly like a blender.

Organic Fertilizer Materials

Require fermentation and composting first, crushed to 40-80 mesh, with moisture content controlled in the “golden range” of 20%-30%

Compound Fertilizers

Basic fertilizers like nitrogen, phosphorus, and potassium are mixed in precise proportions, requiring mixing uniformity of over 85%

2. The “Metamorphosis” of Fertilizer Production

From raw materials to finished fertilizer, a gorgeous transformation takes place:

After pre-processed materials enter the granulation cylinder, the water spray device evenly sprays water or binder like spring rain. The high-speed rotation of stirring teeth generates strong centrifugal force, causing materials to gradually agglomerate into 1-5 mm pellets through collisions.

Newly formed pellets must pass through the screening “quality checkpoint,” with unqualified pellets sent back for “reprocessing.” Qualified pellets then enter the drying and cooling stage, with moisture reduced to below 10% and temperature lowered to room temperature, finally dressed in the “clothing” of woven bags or plastic bags, ready to head to the fields.

Interestingly, the entire granulation process is like making meatballs – it requires the right “mince” (raw materials), appropriate “mixing intensity” (rotation speed), and proper “moisture” (binder) to produce uniformly sized “meatballs” (fertilizer pellets).

This seemingly simple machine is actually an important promoter of agricultural modernization. It not only improves fertilizer utilization and reduces resource waste but also saves farmers from the toil of manual fertilization. Next time you see neat, uniform fertilizer pellets, remember the “magician” working silently behind them.

Common troubleshooting and solutions for double screws compost turning machines

Double screws compost turning machines operate frequently in organic fertilizer fermentation workshops. Improper operation or untimely maintenance can easily lead to problems such as uneven turning, insufficient power, and equipment jamming, impacting fermentation progress.

1. Dead corners remain after turning, and some areas remain uncomposted

The main cause is excessive clearance between the spiral blades and the sidewalls of the fermentation tank (over 10 cm), or the double screws compost turning machine is moving too fast, preventing material from being turned over the edges. To address this, adjust the position of the spiral blades to reduce the clearance to within 5 cm. Also, reduce the double screws compost turning machine’s speed to ensure that every area is thoroughly turned.

2. Motor overload and tripping, insufficient power

This is often caused by excessive moisture content (over 70%) in the raw materials, resulting in increased friction on the spiral blades due to high viscosity, or by large impurities in the raw materials that may be blocking the blades. To address this, adjust the moisture content of the raw materials to 60%-65% before clearing impurities from the fermentation tank. If the compost tank is frequently overloaded, check the tightness of the motor belt and tighten or replace it.

3. Rapid wear of spiral blades, reducing turning capacity

This is primarily due to the presence of hard impurities (such as sand and gravel) in the raw materials, or the blade material not being suitable for wear resistance. To address this, install a screen to filter out hard particles before the raw materials arrive. Regularly inspect the blades for wear. If the blade thickness has decreased by 1/3 or cracks appear, replace them promptly.
