by organic fertilizer production line

 How to transform loose powder into high-strength pellets? This industrial magic system has the answer

In modern fertilizer production, the transformation from raw materials to uniform fertilizer granules compaction represents a critical industrial process. This journey begins with specialized equipment like the fertilizer compaction machine, which applies tremendous pressure to convert fine powders into dense pellets. The complete fertilizer production machine ecosystem ensures consistent size, strength, and quality in every batch. This revolutionary roller press system has redefined efficiency across industries, turning volatile powders into perfectly formed pellets through a seamless, automated process that combines raw power with precision engineering.

The Perfect Transformation Journey

Imagine raw powder materials like fresh winter snow—soft yet unshapely. The roller press granulation line acts like an experienced sculptor, with crushers “carving” materials to ideal particle size through precise pretreatment, while vibrating screens work like meticulous gardeners removing impurity “weeds.” This preparatory combination lays solid groundwork for the magnificent transformation ahead.

The roller compactor’s twin-roll design resembles two slowly converging steel mountains, applying up to 200MPa pressure—equivalent to 2 tons per square centimeter! This tremendous squeezing force instantly converts loose powder into dense sheets, subsequently cut into uniform pellets by precision granulation blades.

The Intelligent Quality Guardian

The screening system serves as the production line’s strict quality inspector, separating pellets into “honor students,” “repeaters,” and “dropouts” through multi-layer vibrating screens. Substandard pellets either return to crushers for “remedial classes” or get automatically rejected. Meanwhile, the PLC control system acts as the brain, monitoring over 30 real-time parameters including pressure, moisture and temperature to ensure each pellet meets rigorous standards.

Automated Grand Finale

After passing all quality checkpoints, the automatic packaging system begins its performance: high-precision load cells ensure each bag’s weight is accurate to the gram, heat sealers apply perfect-temperature closures, while labeling robots affix “ID cards” to each product with mechanical arms. From raw material intake to finished product outbound, the entire process flows like an industrial ballet.

Across chemical, fertilizer, pharmaceutical and other industries, roller press granulation lines are redefining pellet manufacturing standards with exceptional efficiency and consistency. This system achieves not just physical transformation from powder to pellets, but demonstrates modern industry’s magic in converting simple materials into high-value products.

by organic fertilizer production line

In modern agricultural Production, we often hear the term “Fertilizer Production Line,” which covers the production of a range of fertilizers, from nitrogen fertilizer to phosphate fertilizer to potassium fertilizer. However, in addition to these well-known NPK fertilizers, other important nutrients in organic fertilizers are equally indispensable. Today, we talk about these unsung heroes.
First, let’s introduce the Organic Fertilizer Production Line. Imagine that you are a farmer and your land needs a special kind of nourishment. At this time, the Organic Fertilizer Production Line is like a chef. It converts various organic raw materials, such as livestock manure and crop stalks, into nutrient-rich organic fertilizers through a series of processing processes, such as compost treatment. These fertilizers not only provide a variety of trace elements needed for plant growth, but also improve the soil structure and enhance the soil’s water retention and permeability.
Next, let’s talk about Rotary Drum granulators. The Rotary Drum Granulator plays a vital role in the production of organic fertilizers. It extrudes the mixed raw materials into pellets through a rotating drum, which not only facilitates the storage and transportation of fertilizers, but also improves the application efficiency of fertilizers. Granular organic fertilizers can be more evenly distributed in the soil when applied, thus better promoting plant absorption.

New Type Organic Fertilizer Granulator: High-Efficiency Equipment Empowering Multi-Sector Production

by organic fertilizer production line

In response to the need for industrial upgrading, the new type organic fertilizer granulator (models YSL-60 to YSL-150) was developed by the Agricultural Machinery Research Institute. Leveraging its accumulated experience in compound fertilizer processing and its unique mixing and granulation method, it has become a practical device for granule production in various fields.

In terms of core technology, the new type organic fertilizer granulator utilizes high-speed rotating stirring teeth to stir, impact, and tumble the mixed material within the granulation drum. Friction, centrifugal force, and the material’s viscosity aggregate the material into granules, eliminating the need for complex extrusion equipment and making it suitable for high-viscosity or fibrous materials. Performance parameters include a production capacity of 1-8 tons/hour, motor power of 37-90 kW, and granule diameter of 1-5 mm. The YSL-60 produces 1-2 tons per hour, making it suitable for small and medium-sized operations; the YSL-150 produces 5-8 tons per hour, making it suitable for large-scale production.

It has a wide range of applications. In the fertilizer sector, livestock and poultry manure, straw, and other materials can be transformed into organic, bio-organic, and compound microbial fertilizers, eliminating caking issues while preserving bacterial activity and producing medium and trace element fertilizers. In the chemical industry, it can be used to granulate sticky raw materials; in the pharmaceutical industry, it can process traditional Chinese medicine granules; and in the feed industry, it can produce livestock and aquatic feed, achieving a “one machine for multiple uses.”

The core advantages are significant. Granulated particles are round and uniform, with good flowability, and are less prone to clumping during storage and transportation. Operation is simple, requiring only training. The low motor power and operating costs make the equipment affordable, making it suitable for small and medium-sized enterprises. Furthermore, it preserves fertilizer activity, extending its shelf life to 8-12 months, promoting the recycling of organic waste and achieving both economic and environmental benefits.

Daily maintenance requires three key points: regular inspections: daily inspection of the feed mechanism and transmission system; weekly inspection of agitator tooth wear; monthly bolt tightening and motor temperature monitoring; cleaning the granulation drum after production; lubricating transmission components according to specifications, and timely replacement of worn parts to ensure stable equipment operation.

This new type organic fertilizer granulator, with its multiple advantages in technology, performance and application, is providing strong support for production upgrades in agriculture, chemical industry, medicine, feed and other fields.

Key Considerations for Bio-Organic Fertilizer Production Lines

by organic fertilizer production line

A bio-organic fertilizer production line requires consistent equipment processes and standardized operations to consistently produce high-quality fertilizer. During production, five key considerations must be carefully considered, focusing on each key stage of the production line.

Raw material pretreatment is fundamental. Before feeding the bio-organic fertilizer production line, impurities such as gravel and plastic must be removed through a screening machine to prevent damage to equipment such as grinders and mixers. A crusher is then used to grind materials such as straw and mushroom residue to a particle size of 2-5 mm to ensure uniform mixing with livestock and poultry manure. The carbon-nitrogen ratio is also adjusted through online monitoring. If the carbon-nitrogen ratio deviates from 25:1-30:1, urea or straw powder can be precisely added through an automatic dosing device to ensure raw material compatibility.

The fermentation stage requires coordinated equipment and processes. When using windrow or trough fermentation equipment, the pile height should be set at 1.2-1.5 meters. Temperature sensors should be used to monitor the pile temperature in real time. When the temperature reaches 55-65°C, a turning machine should be activated to turn the pile every 3-5 days to ensure even aeration. A humidity control system should also be activated to automatically spray water if the moisture content is below 60%, and add dry materials if it exceeds 65% to prevent spoilage and bacterial inactivation.

Prevent quality loss during further processing. Before entering the pelletizer, the fermented material must pass through a dryer to reduce the moisture content to below 20% to prevent clumping during pelletizing. During pelletizing, the particle size should be controlled at 2-4 mm to avoid uneven particle size that could affect subsequent packaging and application. All processing equipment, such as the pulverizer blades and pelletizer molds, requires regular lubrication and maintenance to prevent equipment failures that could cause production interruptions or increase impurities in the fertilizer.

Quality testing must be conducted throughout the bio-organic fertilizer production line. Sampling points are set up at the raw material inlet, after fermentation, and at the finished product outlet to conduct real-time testing of the raw material’s heavy metal content, the fermentation material’s viable bacterial count, the finished product’s organic matter content (≥30%), and its pH value (5.5-8.5). This ensures compliance with GB/T 20287-2006 standards at each stage and prevents unqualified materials from flowing into the next stage.

The packaging and storage stages ensure the final activity of the fertilizer. At the end of the production line, the fertilizer is packaged using an automatic packaging machine in breathable, moisture-proof woven bags printed with information such as the production date and viable bacterial count. After packaging, the bags are transported via conveyor belts to a ventilated warehouse, stacked no higher than 1.5 meters and away from heat sources on the production line (such as dryers). The shelf life is controlled within 6 months to ensure the fertilizer maintains high activity after leaving the factory.

Crushing process of organic fertilizer production line

by organic fertilizer production line

In an organic fertilizer production line, the crushing process is the “throat” of the entire line, directly determining raw material processing efficiency and final product quality. It is the core link between raw material pretreatment and subsequent fermentation and granulation processes. Whether it is agricultural waste such as livestock and poultry manure, straw, and mushroom residue, or organic raw materials such as restaurant waste and garden branches, they all require scientific crushing to achieve “fragmentation” and lay the foundation for subsequent processes.

The primary task of the crushing process is to break down the raw materials’ physical structure and address the issues of uneven size and hardness among different raw materials. For example, unpulverized livestock and poultry manure may contain lumps such as straw residue and hair. If directly fed into the fermentation process, this can lead to imbalanced material permeability and localized anaerobic decay. Fibrous raw materials such as straw and branches require pulverization to reduce the particle size to 5-10 mm, making it easier for microorganisms to decompose the fiber structure and shortening the fermentation cycle. Currently, mainstream production lines mostly use cage crushers for fine grinding. For some large, hard raw materials, pre-screening is performed to remove oversized impurities before the raw materials enter the cage crusher, ensuring a particle size uniformity of over 90%.

Technical control in this process directly impacts the efficiency and product quality of the organic fertilizer production line. First, the particle size must be adjusted dynamically based on the raw material type: when processing high-moisture manure, the grinding fineness must be appropriately controlled to prevent clumping; when processing straw with a high lignin content, the particle size must be refined to improve composting maturity. Second, controlling dust and impurities during the grinding process is crucial. Reputable production lines install magnetic separation devices at the grinder inlet to remove metal impurities and bag filters at the discharge to meet environmental requirements and minimize equipment wear.

It is important to note that the finer the grinding process, the better. Excessive grinding not only increases energy costs but can also reduce the material’s aeration during fermentation, ultimately prolonging composting time. Industry practice demonstrates that crushing raw materials to a particle size that “clumps together in the hand and falls apart with a light squeeze” not only ensures microbial activity but also improves the yield rate in the subsequent granulation process. High-quality pulverization is a prerequisite for producing organic fertilizer products with uniform particles and meeting organic matter content standards. It is also a key step in promoting the efficient resource utilization of agricultural waste.

The production process of an NPK fertilizer production line

by organic fertilizer production line

NPK fertilizer contains three core nutrients: nitrogen, phosphorus, and potassium. Its production requires a precise process to ensure balanced nutrients and consistent quality. Every step, from raw materials to finished product, integrates industrial technology with agricultural needs.

The first step in production is raw material pretreatment. Raw materials such as urea, monoammonium phosphate, and potassium chloride are first crushed to 80-100 mesh in a crusher. They are then screened through a vibrating screen to remove impurities and ensure raw material purity, which is essential for subsequent fertilizer dissolution and absorption.

Next comes batching and mixing. The production line relies on an automated control system to precisely weigh the raw materials according to preset formulas such as 15-15-15 and 20-10-10. The raw materials are then fed into a twin-shaft mixer, where they are stirred at high speed for 3-5 minutes to create a uniform mixture, preventing imbalanced crop growth due to uneven nutrient distribution.

Then, the granulation process begins. The mixed material is conveyed to a rotary drum granulator, where centrifugal force and friction aggregate the material into 2-4 mm granules as the drum rotates. Some production lines spray a binder to enhance hardness and prevent breakage. The granules are initially screened at the exit, and unqualified fines are returned to the mixing stage for recycling.

After granulation, they are dried and cooled. First, they enter a drum fertilizer dryer, where hot air at 120-150°C reduces the moisture content to below 10%. They then enter a cooler, where countercurrent heat exchange with cold air cools them to room temperature, preventing clumping, extending shelf life, and improving granule stability.

Finally, they undergo screening and packaging. The cooled granules pass through a vibrating screen to separate the coarse particles (returned to the crusher) from the fines (returned to the granulator). Qualified granules are then bagged by an automatic packaging machine in sizes ranging from 25 kg to 50 kg. Labels are then applied with the formula and production date, and the bags are then stored for shipment, providing nutrition for crops.

The NPK fertilizer production line uses an automated and precise process to convert chemical raw materials into agricultural “nutrients”, ensuring quality while supporting the efficient development of modern agriculture.
