The ring die granulator is a core piece of equipment in organic fertilizer production lines. Its performance directly affects pellet formation rate, production efficiency, and product quality. Optimizing it not only increases output but also cuts energy use and lowers maintenance costs.

1.Die Hole Size and Compression Ratio
Adjust hole size based on material properties: Different organic raw materials (like livestock manure, straw, or sludge) have varying viscosity and moisture levels, requiring different hole sizes (typically 2.5–6 mm).
Optimize compression ratio: Too high a ratio increases energy use; too low affects pellet hardness. Adjust based on material (generally 1:5–1:8).
2.Raw Material Moisture and Fineness
Control moisture at 20%–30%: Too high causes clogging; too low hampers shaping. Adjust through drying or water spraying.
Keep particle size ≤1mm: Finer material improves granulation, reduces return rate, and boosts output.

3.Roller and Die Compatibility
Set roller gap (0.1–0.3mm): Too wide lowers forming rate; too narrow speeds up wear.
Check roller wear regularly: Uneven wear causes inconsistent pellets. Replace or repair promptly.
4.High-Quality Wear-Resistant Materials
Use alloy steel or carburized rings to improve wear resistance and extend service life.
Apply surface hardening to rollers to reduce friction and replacement frequency.

By rationally adjusting the ring die parameters, optimizing raw material processing, and strengthening equipment maintenance, the output and stability of the fertilizer granulator can be significantly improved. This improves efficiency while lowering operating costs, delivering greater value for producers.

Roller Compaction Granulator: The Future of Eco-Friendly Particle Processing?

Written by fertilizer production line on August 29th, 2025. Leave a comment

In today’s pursuit of green manufacturing, roller compaction granulators are reshaping particle processing with unique advantages. These innovative NPK fertilizer granulator machines achieve remarkable efficiency and energy savings in the NPK production process through advanced compaction technology. Let’s uncover the secrets behind their sustainable performance and operational excellence.

Revolutionary Working Principle

The essence of the roller compaction granulator lies in its ingenious design – two identical rollers rotating in opposite directions at the same speed. When precisely proportioned raw materials are forced into the roller gap, the magic begins: tremendous pressure expels air from the material, reduces particle spacing, enhances intermolecular forces, and ultimately forms dense flakes or strips.

Notably, the pressure variation follows an exact pattern: peaking at the horizontal position of the rollers (often reaching several megapascals), then rapidly decreasing. This intelligent pressure regulation ensures the formed material can perfectly detach from the roller surface through its own elasticity, ready for subsequent processes.

Unparalleled Energy Efficiency

Compared to traditional wet granulation, roller compaction technology represents a quantum leap. It completely eliminates the energy-intensive drying process, reducing energy consumption by 50%-70%! This means not only significant cost savings but also respect for Earth’s resources.

Even more exciting is the truly “zero-emission” production process – no wastewater, no exhaust gases, no waste residue. With increasingly stringent environmental regulations, this clean technology undoubtedly offers enterprises the best choice for sustainable development.

A Future-Oriented Manufacturing Solution

The roller compaction granulator perfectly embodies the harmony between “efficiency” and “environmental protection.” Its compact design, simple operation, and low maintenance costs make it an ideal choice for modern manufacturing enterprises.

As the world’s pursuit of green manufacturing intensifies, this technology will undoubtedly see broader applications. It’s not just a piece of equipment, but a significant milestone in the industrial sector’s transition to sustainable development.

Granulation Process and Equipment Advantages of the New Type Organic Fertilizer Granulator

Written by fertilizer production line on August 29th, 2025. Leave a comment

The new type organic fertilizer granulator utilizes the mechanical agitation force of high-speed rotation and the resulting air dynamics to continuously mix, granulate, spheroidize, and compact fine powders within the machine, achieving the desired granulation effect.

The resulting granules are spherical with a sphericity ≥0.7, a particle size generally ranging from 0.3 to 3 mm, and a granulation rate ≥80%. Particle size can be adjusted appropriately by adjusting the material mixing ratio and spindle speed. Generally, lower mixing ratios and higher spindle speeds result in smaller particles, and vice versa. This machine is suitable for granulating lightweight, fine powders. The finer the basic particles of the fine powder, the higher the sphericity and the better the particle quality. The particle size before granulation is generally required to be less than 300 mesh.

Typical applications of the new type organic fertilizer granulator include chicken manure, pig manure, cow dung, charcoal, clay, kaolin, and other materials. The new type organic fertilizer granulator boasts uniform granulation and a yield rate exceeding 97%, making it the optimal granulation equipment for organic-inorganic compound fertilizers, organic fertilizers, and bio-organic fertilizers. Due to the coarse fiber properties of the material, rotary granulators have a lower granulation rate, while agitator-type granulators cannot process materials with a nitrogen content exceeding 8% (due to sticking to the wall). This granulator overcomes the shortcomings of both, capable of producing both organic and organic-inorganic compound fertilizers with low energy consumption and high-quality granulation.

The new type organic fertilizer granulator‘s housing is welded from thickened, high-quality carbon steel plates. Ancillary equipment includes pulley assemblies, transmission components, a blower head, and a blower tail. The entire machine is sturdy and durable. The core agitator is precision-cast from a high-chromium alloy and undergoes a special heat treatment, resulting in wear resistance over three times greater than that of ordinary steel. It can withstand the high-frequency friction of fine powders for long periods of time. The main shaft and agitator blades feature a modular design and are fastened with high-strength bolts, enabling easy assembly and simple component replacement, reducing maintenance costs. Adjustable support feet on the bottom of the machine adapt to the flatness of the site, ensuring stable operation and reducing vibration-induced noise and component wear.

3.Organic Waste Treatment Centers Near Cities

As cities adopt waste sorting, demand for organic waste processing grows. Building fertilizer plants near urban areas can handle kitchen waste, garden trimmings, and other organic materials.

4.Self-built Fertilizer Plants on Large Farms

Big farms with major crop bases gain clear advantages by building their own lines: they can customize fertilizer formulas for their crops, use farm waste like straw as raw material, cut fertilizer costs, and improve crop quality.

No matter which type you choose, setting up a bio-organic fertilizer production line also requires considering raw material supply and transport. With careful site selection, the production line will run at its best.

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

Written by fertilizer production line on August 28th, 2025. Leave a comment

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

Written by fertilizer production line on August 28th, 2025. Leave a comment

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.

Analysis of the Complete Fertilizer Production Process on an Organic Fertilizer Production Line

Written by fertilizer production line on August 28th, 2025. Leave a comment

Organic fertilizer production lines use scientific processes to transform agricultural and livestock waste into high-quality fertilizer, achieving resource recycling. The entire production process revolves around four core steps: raw material processing – composting – forming – packaging, and each step directly impacts fertilizer quality.

The first step is raw material pretreatment. The production line collects raw materials such as livestock manure, straw, and mushroom residue, and uses screening equipment to remove impurities such as stones and plastic to prevent them from affecting subsequent processes. Next, a crusher is used to pulverize the straw and other coarse fiber materials to a particle size of 5-10mm. The material is then mixed with livestock manure in a ratio of approximately 3:7. A small amount of fermentation inoculant is added, adjusting the carbon-nitrogen ratio to 25:1-30:1 and controlling the moisture content to 50%-60%, laying the foundation for fermentation and composting.

The second step is fermentation and composting. The mixed raw materials are transported to the fermentation workshop and stacked in windrow or tank-type fermentation equipment. During the fermentation process, a compost turning machine regularly turns the material to ensure adequate oxygen and regulate the temperature. The entire fermentation cycle lasts approximately 20-30 days. After composting, the material transforms into a dark brown, odorless humus. It then passes through a cooling device to a temperature below 30°C to prevent nutrient loss during subsequent processing.
The third step is further processing and shaping. The cooled composted material is first crushed to a particle size of 2-3mm in a fine grinder. It is then mixed with a small amount of auxiliary materials such as bentonite and humic acid in a mixer to enhance the fertilizer’s stability. The material then enters the granulation stage, where a rotary drum or disc granulator physically agglomerates the material into 2-5mm granules. The granules are then dried (controlled at 60-80°C) to reduce moisture to below 15%, cooled in a cooler, and screened to separate unqualified particles. The fine powder is then returned to the granulator for reuse.
The finished product is then packaged. Qualified pellets are transported to the packaging workshop, where an automatic packaging machine weighs and seals them into 25kg or 50kg packages, producing finished organic fertilizer.
In short, the organic fertilizer production line, through standardized and mechanized full-process control, efficiently transforms waste into high-quality fertilizer, contributing to environmental protection while providing green nutrients for agriculture.

NPK fertilizer production lines are a key enabler for agricultural development.

Written by fertilizer production line on August 28th, 2025. Leave a comment

NPK fertilizer (nitrogen-phosphorus-potassium compound fertilizer) production lines are core equipment for modern agriculture. By scientifically blending nitrogen, phosphorus, and potassium, they provide precise nutrients to crops. This is of great significance to high-quality agricultural development, and its impact is reflected in three key areas.

NPK fertilizer production lines are a stabilizer for ensuring food security. With population growth and limited arable land, increasing yields is crucial. NPK fertilizer production lines can customize balanced compound fertilizers based on the fertilizer needs of crops like wheat and rice, addressing the nutrient deficiencies of traditional single fertilizers. Data shows that high-quality NPK compound fertilizers can increase grain yields by 15%-25% per mu, effectively alleviating pressure on food supply and strengthening national food security.

NPK fertilizer production lines are an accelerator for promoting agricultural modernization. Traditional fertilizer production relies on manual labor, resulting in low efficiency and uneven nutrient distribution. NPK production lines, however, fully automate raw material mixing, granulation, drying, and packaging. A modern production line can produce hundreds of tons of fertilizer per day, significantly improving efficiency. Precise temperature and humidity control ensures uniform fertilizer particles and consistent nutrient content, reducing fertilizer waste and helping transform agriculture from extensive to intensive farming.

NPK fertilizer production lines are the “guardians” of sustainable agriculture. Today, NPK production lines can incorporate slow-release technology to produce slow-release compound fertilizers, which slowly release nutrients, prolong fertilizer effectiveness, and reduce soil and water pollution caused by fertilizer runoff. Some lines can also utilize agricultural waste such as straw and livestock manure as auxiliary materials, achieving resource recycling and reducing the environmental impact of chemical fertilizer production, meeting the needs of green agriculture.

In short, by ensuring yield, improving efficiency, and promoting green development, NPK fertilizer production lines have become an indispensable core force in agricultural modernization, injecting lasting momentum into sustainable agricultural development.
