New type organic fertilizer granulator: Empowering green production in the fertilizer industry

Amid the rise of ecological agriculture and the continued surge in demand for organic fertilizer, new type organic fertilizer granulators, leveraging technological innovations from traditional equipment, have become key equipment for the fertilizer industry, addressing challenges in organic fertilizer granulation and promoting green production.

The most prominent advantage of the new type organic fertilizer granulator is its adaptability to organic fertilizer raw materials. Organic fertilizer raw materials, primarily derived from livestock and poultry manure, straw, and food waste, often exhibit large moisture fluctuations, high fiber content, and prone to clumping. By optimizing the conditioning system and granulation structure, the new equipment can flexibly adjust the raw material moisture and temperature. This allows for uniform granulation even with high-moisture, high-fiber raw materials, significantly improving granulation efficiency and effectively reducing raw material waste.

The new type organic fertilizer granulator is also known for its “green and efficient” design. By upgrading its transmission system and adding a dust collection device, the new equipment achieves low energy consumption and low pollution while improving production efficiency.

Furthermore, the new type organic fertilizer granulator can help enhance the competitiveness of organic fertilizer products. The organic fertilizer particles it produces have uniform density, moderate hardness, and are not easy to break; more importantly, the low-temperature granulation process of the new equipment can maximize the retention of beneficial microorganisms and active ingredients in the organic fertilizer, ensuring a longer-lasting fertilizer effect.

Fertilizer granulators contribute to efficient agricultural development

With the agriculture and fertilizer industries deeply intertwined, fertilizer form directly impacts fertilization effectiveness and industry efficiency. As the core equipment connecting fertilizer raw materials and finished products, fertilizer granulators are becoming a key driver of industry upgrades.

Fertilizer granulators transform powdered raw materials into uniform fertilizer granules through processes such as physical extrusion and conditioning. These granulated fertilizers are not only highly stable, making them suitable for long-term storage and long-distance transportation, but also enable a slow release of nutrients, extending the fertilizer’s effective lifespan and enabling more efficient crop absorption, thereby boosting agricultural production returns from the source.

Furthermore, the adaptability of fertilizer granulators meets the diverse needs of the industry. Whether producing organic fertilizers, compound fertilizers, or customized fertilizers for specific crops, the equipment can adapt to different raw material ratios by adjusting parameters. More importantly, modern fertilizer granulators continuously optimize energy efficiency, improving production efficiency while reducing energy consumption.

For fertilizer companies, fertilizer granulators are a powerful tool for enhancing product competitiveness. Against the backdrop of growing demand for high-efficiency fertilizers in agriculture, fertilizer granulators will undoubtedly drive fertilizer production towards greater efficiency, higher quality, and greater environmental protection.

Double roller press granulators are an efficient and stable choice for fertilizer granulation

In fertilizer production, the granulation process directly impacts fertilizer application convenience, storage stability, and nutrient utilization. Due to its unique technological advantages, double roller press granulators (commonly known as fertilizer compaction machines) are the preferred equipment for many production scenarios. They can transform a variety of fertilizer raw materials into uniform granules without complex pretreatment, offering both adaptability and practicality.

The operating principle revolves around “physical extrusion.” Crushed and mixed fertilizer raw materials are conveyed between two pairs of counter-rotating extrusion rollers at the core of the equipment. Under pressure from the roller surfaces, the raw materials are compressed into continuous flakes. These flakes then enter a crushing unit, breaking them into irregular particles. Screening equipment then selects the finished product that meets the required particle size.

The core advantages of double roller press granulators lie in their flexibility and energy efficiency. Requiring no binders, granulation relies solely on the raw materials’ inherent physical properties, preserving the natural properties of organic fertilizers or the nutrient purity of compound fertilizers. This eliminates the high-temperature drying step required in traditional granulation. Whether processing organic fertilizer, compound fertilizer, or functional bio-fertilizer, stable granulation can be achieved by simply adjusting parameters such as extrusion pressure and roller speed, providing an efficient solution for fertilizer production.

Rotary drum granulators optimize the nutrient content and application experience of organic fertilizer granules

The core value of organic fertilizer lies in nutrient supply and convenient application, and granule shape directly impacts these two properties. Insufficient nutrient retention reduces fertilizer efficiency, while uneven granules increase the difficulty of field application. By optimizing process details, rotary drum granulators can reduce nutrient loss during the granulation process while creating granule shapes that meet field needs.

In terms of nutrient retention, the rotary drum granulator’s low-temperature granulation is particularly advantageous. Relying on physical tumbling to form granules, the granulator eliminates the need for high pressure and maintains an internal temperature below 35°C, maximizing the retention of active ingredients in the raw materials. Its nutrient retention rate is 5%-8% higher than that of traditional equipment.

In terms of granule application experience, granules produced by rotary drum granulators better meet field needs. On the one hand, the equipment can produce uniform granules with a diameter of 2-5mm by adjusting the drum speed and die aperture, making it easier for farmers to apply fertilizers using seed drills and reducing the unevenness of manual spreading. On the other hand, the moderate hardness of the granules (compressive strength of 10-15N) prevents them from breaking down during transportation and slowly disintegrates in the soil, achieving “slow-release fertilizer supply” and avoiding the root burn caused by concentrated nutrient release.

For organic fertilizer companies pursuing “high quality and low price,” the high-nutrient, easy-to-apply granules produced by the rotary drum granulator can significantly enhance their product’s market competitiveness.

Bio-organic fertilizer equipment selection and maintenance: Helping reduce costs and increase efficiency

For bio-organic fertilizer manufacturers, selecting and effectively utilizing bio-organic fertilizer equipment is crucial for achieving sustainable profitability.

When selecting equipment, consider your production capacity and the characteristics of your raw materials. If your company uses livestock manure as its primary raw material, you should prioritize equipment with strong pretreatment capabilities to avoid high moisture content that could affect fermentation. If your production capacity is under 5,000 tons/year, you can choose small or medium-sized complete sets of equipment to reduce initial investment. If your production capacity exceeds 10,000 tons, you should consider highly automated production lines to reduce labor costs.

Secondly, pay attention to the bio-organic fertilizer equipment’s durability. Equipment for core processes like fermentation and granulation should be constructed of corrosion and wear-resistant materials to withstand the corrosive nature of organic fertilizer raw materials and extend their service life.

Daily maintenance is equally crucial. After use, promptly clean any residual material from components like fermentation tanks and granulators to prevent it from clumping and becoming moldy, potentially contaminating the raw materials during the next use. Regularly check the lubrication of the equipment’s transmission components. Oil depletion can lead to increased wear and tear, increasing the likelihood of failure.

Scientific selection and operation and maintenance can not only reduce the downtime of bio-organic fertilizer equipment and ensure production continuity, but also reduce maintenance costs and improve product qualification rate.

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.

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 can routine drum fertilizer dryer operation and maintenance achieve energy savings and cost reduction?

Drum fertilizer dryers account for 25%-30% of a fertilizer production line’s total energy consumption. Whether routine operation and maintenance are effective directly impacts a company’s operating costs.

  1. Accurate Maintenance of Thermal Efficiency

Hot air is the core energy source of a drum fertilizer dryer. The pipes connecting the hot air furnace and the drum must be regularly inspected. Damaged pipe insulation can lead to heat loss (up to 10% or more) and require prompt repair or replacement. Clean accumulated slag in the hot air furnace to ensure complete fuel combustion, increase thermal efficiency to over 75%, and reduce fuel waste.

  1. Dynamic Adjustment of Drum Operating Parameters

Adjusting operating parameters based on changes in raw material moisture content can avoid inefficient energy consumption. When the moisture content of the wet material is low, appropriately reduce the hot air temperature and increase the drum fertilizer dryer speed (shortening the dwell time). When the moisture content is high, adjust the opposite direction. This ensures that every unit of energy consumed is used for effective dehydration, avoiding the waste of high energy consumption processing low-moisture materials.

  1. Preventive Replacement of Wear Parts

Worn drum seals (such as the seals at the feed and discharge ports) can cause cold air to infiltrate and hot air to leak, increasing the heating load. Check the seals monthly and replace any signs of aging or deformation. Also, regularly inspect the lift plate. If loose or worn, tighten or replace it promptly. Simple preventive maintenance can significantly reduce future failures and energy costs.

Drum fertilizer dryers: Why can they adapt to the different drying requirements of organic and compound fertilizers?

In the fertilizer industry, the drying requirements of organic and compound fertilizers differ significantly. Organic fertilizers require rapid dehydration and fiber clumping prevention, while compound fertilizers require gentle drying to prevent particle breakage.

For drying organic fertilizers, drum fertilizer dryers offer two key design advantages: First, they utilize a “high-speed + multiple lifter” combination. High speed combined with dense lifters effectively lifts fibrous materials, preventing entanglement and clumping. Hot air also directly penetrates the material layer, quickly removing moisture. Second, an anti-stick coating on the inner wall of the drum reduces wet organic fertilizer from sticking to the wall, reducing cleaning frequency and ensuring continuous production.

For drying compound fertilizers, the drum fertilizer dryer emphasizes “gentle temperature control + low speed”: steam heating is used, keeping the temperature between 120-150°C to avoid direct contact with high temperatures that could cause cracking on the particle surface. Furthermore, a reduced drum speed reduces particle friction within the drum, keeping the particle breakage rate below 3%.

Even when processing temperature-sensitive biofertilizers, the drum fertilizer dryer can adapt to these needs through a “low-temperature hot air modification.” This reduces the hot air temperature to 60-80°C, prolonging the material’s residence time. This allows for slow dehydration while maintaining a microbial survival rate above 85%, truly achieving “one device, multiple fertilizers.”
