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

by organic fertilizer production line

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

by organic fertilizer production line

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.

Key Maintenance Points for Disc Granulators in Organic Fertilizer Production Lines

by organic fertilizer production line

In organic fertilizer production lines, the disc granulator is the core equipment for raw material processing. Its operating condition directly affects product quality and production efficiency. Scientific maintenance can extend equipment life, reduce downtime, and lower costs. The following details maintenance methods from three perspectives: daily, periodic, and long-term.

Daily maintenance requires “cleaning and inspection in tandem.” After each shutdown, promptly clean the discs of residual material to prevent hardening and scratching of the disc surface or increased operating load. Use soft tools to prevent damage to the liner. Also, check the disc’s tilt angle (normally 45°-55°). If offset, correct it using the bracket bolts. Observe the transmission system daily for abnormal noise and check the motor and reducer temperatures. If the temperature exceeds 60°C, shut down the machine for inspection.

Regular maintenance focuses on “component maintenance and lubrication.” Perform a comprehensive weekly inspection, focusing on the meshing of the transmission gears. Adjust and replace any wear or excessive clearance. Inspect the bearing seals to prevent dust intrusion. Replace the bearing grease monthly. Choose a high-temperature, dust-resistant lithium-based grease, filling it to fill 2/3 of the bearing’s internal space. Disassemble and inspect the scraper blade quarterly. If the blade wear exceeds 3mm, polish or replace it. Ensure a 1-2mm gap between the blade and the liner to prevent material adhesion.

For long-term maintenance, maintain “equipment inspection and record keeping.” Perform a comprehensive annual disassembly and inspection. If the liner thickness decreases by 1/3, replace it entirely. Perform a flaw inspection on the frame to identify any weld cracks and repair them. Maintain a maintenance log, recording maintenance times, details, and replaced parts. Use data analysis to predict failures and plan maintenance in advance.

In short, disc granulator maintenance should adhere to the principle of “prevention first, prevention combined.” This involves combining daily cleaning, regular maintenance, and ongoing inspections to ensure optimal equipment operation and a stable and efficient organic fertilizer production line.

Production process of fertilizer granules using a rotary drum granulator

by organic fertilizer production line

The rotary drum granulator is a core piece of equipment for producing compound fertilizers, organic fertilizers, and NPK fertilizers. It transforms powdered raw materials into uniform granules through physical tumbling and chemical binding.

1.Raw Material Preparation
Powdered raw materials are crushed and screened to ensure uniform particle size. This improves granulation efficiency and granule strength. Nutrient ratios (nitrogen, phosphorus, potassium, etc.) are adjusted according to the formula to ensure balanced nutrition in the final product.
2.Mixing and Moistening
Materials enter the rotary drum granulator, where liquid (water, steam, or a binder) is sprayed in. This moistens the material surface, promoting granule formation. Liquid spraying must be precisely controlled—too much causes over-wetting and clumping, while too little reduces granulation rates.
3.Tumbling and Granule Formation
The drum rotates at a suitable speed (typically 10-20 rpm). Material rolls and agglomerates under centrifugal force and friction, forming initial granules. Internal baffles may be installed to improve mixing and granule uniformity.
4.Drying and Screening
Newly formed granules move to a dryer to remove excess moisture, improving hardness and storage stability. After vibrating screening, qualified granules proceed to coating or packaging. Fine powder is recycled back to the granulator, reducing waste.

Factors Affecting Granulation Efficiency
1.Drum Rotation Speed: Low speed slows granule formation; high speed risks breaking granules.
2.Liquid Spray Method: Atomized spray ensures even distribution and higher granulation rates.
3.Raw Material Ratio: Proper nutrient balance and binder selection impact granule strength and solubility.
4.Temperature Control: Moderate heating speeds up moisture removal and drying efficiency.

By adjusting parameters like rotation speed, liquid spray volume, and material ratios, the rotary drum granulator process can be optimized to produce uniform, strong granules with excellent slow-release properties.

How Are Perfect Fertilizer Granules Made? The Magic of Compaction!

by organic fertilizer production line

 Have you ever wondered how small, uniform fertilizer granules are produced? The secret lies in an efficient process known as fertilizer granules compaction. With the ability to incorporate over 20 different materials—including essential trace elements like boron, iron, copper, zinc, and manganese—this method is both versatile and efficient.

1. Storage and Precise Measurement

Raw materials such as urea, ammonium phosphate, and potassium chloride are elevated and conveyed into storage bins. The complexity of the mixing system depends on the fertilizer formula, but accuracy is always key.

2. The Heart of the Process: Compaction

This is where the real magic happens. A specialized fertilizer compaction machine, also known as a roller press granulator, exerts tremendous pressure on the mixed powder. As the material passes between two counter-rotating rollers, it’s compressed into a solid plate. The pressure builds, then releases, forming dense sheets ready for the next stage.

3. Crushing and Sizing

The compacted plates are pre-crushed and screened into desired particle sizes. Fine particles are recycled back into the mix, while oversized granules are crushed again. Proper selection of crushers and screens is crucial for economic efficiency.

4. Polishing and Anti-Caking Treatment

Finally, the granules are polished in a rotating drum to smooth edges. Anti-dust and anti-caking agents are added to ensure a clean, free-flowing final product. The result? High-quality, uniform fertilizer granules ranging between 1-4mm.

For single-component fertilizers like granular potassium or ammonium sulfate, the process is even simpler—requiring less equipment and lower investment. Thanks to the efficiency of the fertilizer compaction machine, producing high-quality granules has never been easier!
