fertilizer granulator Aug 26, 2025

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

fertilizer granulator Aug 26, 2025

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

fertilizer granulator Aug 26, 2025

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

fertilizer granulator Aug 26, 2025

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.

Requirements for raw materials in double roller press granulator: How to choose suitable materials?

fertilizer granulator Aug 26, 2025

Double roller press granulators are efficient and energy-saving equipment widely used in producing granular fertilizers like organic fertilizer, compound fertilizer, and bio-fertilizer. However, not all raw materials are directly suitable for extrusion granulation. The physical and chemical properties of the material directly affect the granulation results.

Physical Property Requirements

1.Appropriate Particle Size

Raw materials must be crushed, generally to 80-200 mesh (0.074-0.2mm). Particles that are too coarse make forming difficult, while particles too fine can affect flowability and cause the material to stick to the rollers.

2.Moderate Moisture Content

Excessive moisture (>15%) causes material to stick to the rollers and affects demolding. Insufficient moisture (<8%) makes forming difficult, and the granules become brittle. The optimal moisture range is usually 8%-12%, though this may vary based on material characteristics.

3.Good Plasticity

Materials need some stickiness and plasticity (like humic acid, composted manure, bentonite) to help improve granule formation rate and hardness.

Chemical Property Requirements

1.Moderate Organic Matter Content

For organic fertilizer materials (like compost, humic acid), an organic matter content of 30%-70% is recommended. Too high can lead to loose granules; too low affects fertilizer efficiency.

2.No Corrosive Components

Strong acids, strong alkalis, or high-salt substances should be avoided in the raw materials to prevent equipment corrosion or harm to crops.

3.No Hard Impurities

Hard objects like stones or metal fragments can damage the double roller press granulator die. Screening or magnetic separation is needed before granulation.

Double roller press granulators have strict requirements for raw material particle size, moisture, and binding properties. Selecting suitable materials and optimizing process parameters are essential for producing high-strength, qualified granular fertilizer.

The Bio-Organic Fertilizer Revolution

Raw Material Pretreatment: Where Transformation Begins

On the bio organic fertilizer production line, everything starts with the remarkable transformation of organic waste. Livestock manure, crop straw, and food processing byproducts – these “misplaced resources” – are finely processed by grinders into uniform particles suitable for fermentation. These materials are then scientifically mixed with water and fermentation agents, like concocting a magical “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.
