Fertilizer Processing Process with a Disc Granulator

by organic fertilizer production line

The disc granulator is the core equipment in a fertilizer production line, and its standardized processing flow is crucial for producing high-quality fertilizer.

The first step is raw material preparation. Raw materials include organic materials such as animal manure and plant residues, as well as inorganic materials such as urea and ammonium phosphate. These raw materials must be crushed to reduce particle size for subsequent mixing and granulation. Furthermore, they must be accurately weighed according to the formula to ensure an accurate nutrient ratio, and the humidity must be adjusted to 20%-30% to facilitate granule formation.

The second step is raw material loading. The disc is driven by a motor, and the speed can be set according to the raw material characteristics and the desired particle size. The raw material is evenly distributed on the disc, spread toward the edges due to centrifugal force, and then rises along the inner wall due to friction. After reaching a certain height, it falls back due to gravity, forming a circular motion.

The third step is the application of a binder. As the raw materials circulate, a nozzle above the disc sprays the binder onto the raw materials. The binder is usually a natural polymer or inorganic substance. When it comes into contact with water, it develops viscosity, causing the fine particles to bind together. The spraying rate must be precisely controlled: too much will result in oversized and dense granules, while too little will make them difficult to form.

The fourth step is granule growth. As the disc rotates continuously, the already bonded small granules continuously absorb the raw materials, growing larger as they rotate. The collision and friction between the granules also make them more compact. The operator must observe the granule state and adjust the rotation speed and tilt angle promptly. The rotation speed affects the residence time and granule size, while the tilt angle changes the movement trajectory and helps shape the granules.

The fifth step is discharge. When the granules reach the desired size and quality, they overflow from the edge of the disc. Freshly formed granules contain moisture, which requires drying to reduce the moisture content and improve stability and storage performance.

Through this series of rigorous processes, the disc granulator machine transforms various raw materials into high-quality granular fertilizers, providing strong support for agricultural production.

Fertilizer Granulators: How to Convert Powder into High-Efficiency Granules?

by organic fertilizer production line

In the agricultural sector, NPK fertilizer granulator machine are quietly changing the game in fertilizer production. These machines combine nutrients like nitrogen, phosphorus, and potassium with fillers and transform loose fertilizer powder into uniform granules through mechanical extrusion, rolling agglomeration, or compression molding. This not only reduces transportation and storage costs but also significantly improves fertilizer utilization efficiency.

The fertilizer granulation process is just one of the core steps in a complete fertilizer production line. Prior to this process, the raw materials are crushed in a fertilizer crusher, graded by a fertilizer screener, and evenly mixed in a fertilizer mixer. The granulated particles then pass through a fertilizer dryer to remove moisture, a fertilizer cooler to cool and solidify the pellets, and finally, a fertilizer packaging machine to package them. The precise coordination of this series of equipment ensures the high quality and stability of the final fertilizer product.

Modern fertilizer granulators are becoming increasingly intelligent, with computerized control systems that monitor temperature, humidity, and pressure in real time to ensure a stable and efficient production process. Furthermore, modular designs make equipment cleaning and maintenance easier, reducing downtime and improving production efficiency.

From an economic perspective, investing in a complete fertilizer production line, while initially costly, offers significant long-term returns. Granular fertilizers command higher market prices than powdered fertilizers and are more popular with farmers because they are easier to spread, release nutrients more evenly, and reduce waste and environmental pollution.

The Bio-Organic Fertilizer Revolution

by organic fertilizer production line

Raw Material Pretreatment: Where Transformation Begins

Raw Material Pretreatment: Where Transformation Begins. On the bio-organic fertilizer production line, the remarkable transformation of organic waste starts with a key organic fertilizer production machine: the grinder. This essential fertilizer production machine processes livestock manure, crop straw, and food byproducts into uniform particles. These materials are then scientifically mixed with water and fermentation agents, like an “activation potion,” to create the perfect microbial environment for subsequent processes.

Fermentation Process: A Microbial Feast

The pretreated materials enter fermentation equipment (fermentation tanks or silos), initiating a microbe-led “celebration”. In the organic fertilizer line, this stage is truly the soul of the operation. Through regular turning and precise control of temperature, humidity, and oxygen levels, organic matter is efficiently decomposed at high temperatures, harmful pathogens are eliminated, and the materials ultimately transform into nutrient-rich organic fertilizer substrates.

Precision Processing: Crafting Perfect Pellets

After fermentation, the materials undergo drying to remove excess moisture before entering the crucial stage of bio organic fertilizer production – granulation. Various types of granulators shape the loose materials into uniform pellets, both aesthetically pleasing and convenient for transportation. The screening machines act as strict quality inspectors, ensuring every fertilizer pellet meets standards, with oversized or undersized particles being “recycled”.

Quality Enhancement: From Adequate to Excellent

In the final stage of a modern bio organic fertilizer production line, qualified pellets are uniformly mixed with additives like microbial agents and trace elements, as if donning “nutrient armor” for the fertilizer. Automatic packaging machines dress these “black gold” particles in neat packaging, while rigorous quality testing ensures every bag meets national standards, providing reliable support for green agriculture.

Material requirements for NPK blending fertilizer production line: Key elements for efficient production

by organic fertilizer production line

NPK bulk blend fertilizer (BB fertilizer) is crucial for precision fertilization. Its production quality directly depends on the characteristics of the raw materials. A high-quality NPK blending fertilizer production line has strict requirements for the input materials – only raw materials meeting the standards can guarantee the uniformity and nutrient effectiveness of the final fertilizer.

1.Physical Requirements

Uniform Particle Size (1-4mm optimal): Individual fertilizer particles need very similar sizes (variation within 30%). Recommended materials include rotary drum granulator or extrusion granulated urea, DAP, etc. Avoid directly blending powdered and granular materials.

Moisture Content ≤ 2%: High moisture causes material caking and equipment clogging. Special attention is needed for hygroscopic materials like MOP (muriate of potash) and SOP (sulfate of potash).

Similar Bulk Density: The density difference between components should be within ±20%. Typical density range: 0.9-1.2 g/cm³.

2.Chemical Requirements

Chemical Compatibility: Avoid direct mixing of urea with SSP (single superphosphate) (risk of moisture release). Fertilizers containing nitrate nitrogen are incompatible with liming materials.

Neutral pH: Ideal pH range: 6.5-7.5. Strongly acidic or alkaline materials require pre-treatment.

3.Raw Material Selection Suggestions

Nitrogen Source: Granular urea (large particle), ammonium sulfate (particle size 2-3mm).

Phosphorus Source: MAP (monoammonium phosphate), DAP (diammonium phosphate).

Potassium Source: Granular red MOP (muriate of potash), SOP (sulfate of potash).

Secondary or Micronutrients: Require chelation or coating treatment.

By strictly controlling raw material parameters like particle size, moisture, and density, and by scientifically designing the production process, NPK blending fertilizer production lines can produce high-quality, uniform nutrient, easy-to-apply fertilizers.

How does a rotary drum granulator work in an organic fertilizer production line?

by organic fertilizer production line

In organic fertilizer production lines, a rotary drum granulator is the core equipment for raw material formation. It has become a mainstream choice because it meets the cohesiveness and granularity requirements of organic fertilizers such as livestock and poultry manure and composted straw. Its operation revolves around “raw material mixing – granule agglomeration – screening and output,” resulting in an efficient and stable mechanism.

The equipment primarily consists of an inclined drum (3°-5° inclination), a transmission system, a spray system, and a scraper assembly. Scrapers on the inner wall of the drum drive the material to tumble, while the spray system regulates moisture. The scraper removes material adhering to the drum wall to prevent clogging.

The first step is “raw material pretreatment and feeding.” Composted and crushed organic fertilizer raw materials (25%-35% moisture) are mixed with auxiliary materials such as clay in a suitable proportion and then fed into the drum through the feed port. The motor drives the drum to rotate at a low speed of 10-15 rpm. The scrapers repeatedly lift and drop the material, forming a uniform layer.

The second step is the core “granule agglomeration and formation” phase. A spray device applies a metered amount of water or adhesive, depending on the moisture content of the raw materials, to create a sticky surface. As the drum rotates continuously, the material particles agglomerate into small particles through collision, friction, and compression. These small particles further absorb the raw materials and grow to qualified granules of 2-5mm. The tilted design of the drum allows the particles to naturally move toward the discharge end, enabling continuous production.

The final step is “granule screening and optimization.” The formed granules are screened to separate fine powder from bulky material. The fine powder is returned to the granulator, while the bulky material is crushed and reused to ensure acceptable yields. Furthermore, a scraper cleans the drum wall of any residue in real time to ensure efficiency and prevent hardened residue from affecting subsequent production.

In short, the rotary drum granulator uses gentle physical agglomeration to adapt to the characteristics of organic fertilizer raw materials, efficiently producing uniform granules and providing a key guarantee for the stable operation of organic fertilizer production lines.

Bio-Organic Fertilizer Production Line Equipment Maintenance Guide

by organic fertilizer production line

Bio-Organic Fertilizer production line equipment must cope with the corrosive and sticky nature of mature materials. Scientific maintenance is key to avoiding malfunctions and ensuring product quality. The following summarizes key maintenance points from three perspectives: core equipment maintenance, general maintenance principles, and special precautions.

Core equipment maintenance requires precise implementation. Check the wear of the turning teeth of the fermentation turning machine weekly. Replace any wear exceeding 5mm to prevent uneven turning. Clean the reducer oil and replace the lithium-based grease monthly to prevent damage from high temperatures. Clean residual material from the crushing machine after each shutdown to prevent caking and blockage. Check the hammer gap quarterly to maintain a 1-2mm gap to ensure a consistent particle size. Disc granulators require daily cleaning with soft tools. Bearing grease should be replaced monthly. Liner wear should be inspected annually and replaced if the thickness decreases by 1/3. Clean dust from the heat exchange tubes of the drying and cooling equipment weekly. Check the conveyor belt tension every six months to prevent deviation and slippage.

General maintenance principles must be adhered to throughout the entire process. Before starting up each day, check the motor voltage and current of each device to ensure normal operation. After shutting down, clean the equipment surface and remove any residual material. Tighten the bolts of transmission components monthly to prevent loosening and vibration. Quarterly, inspect equipment seals, such as the crusher feed inlet seal and the dryer door seal, and replace any damaged seals promptly to prevent dust leakage or heat loss.

Special precautions must not be overlooked. Bio-organic fertilizer materials contain microorganisms. After maintenance, equipment must be flushed with a high-pressure water jet to prevent residual material from mold and affecting subsequent production. During the rainy season, electrical cabinets must be protected from moisture, and wiring insulation must be regularly inspected to prevent short circuits. Maintenance records should also be established to record maintenance times and component replacements for each device. This data can be used to predict failures and minimize downtime losses.

In short, maintenance of bio-organic fertilizer production line equipment requires consideration of material characteristics, targeted maintenance of core equipment, adherence to general principles, and attention to specific details to ensure continuous and stable operation of the production line.
