How can you prevent organic fertilizer from “fermenting and spoiling” when using a windrow compost turner?

fertilizer granulator Oct 9, 2025

Many people use windrow compost turners, thinking that “just turning it is enough.” In reality, they fail to pay attention to details, which can easily lead to spoiled compost (turning it black, smelling, or not fermenting thoroughly).
First, adjust the frequency of turning based on the compost temperature. If the compost temperature is below 45°C, microbial activity is low, so turning it every two days is sufficient. Avoid frequent turning. If the compost temperature exceeds 65°C, turn it once a day. Use a windrow compost turner to move the hot material to the surface to dissipate heat and prevent beneficial bacteria from being killed. This will keep the compost temperature stable at 50-60°C, ensuring optimal fermentation.

Second, check the moisture content of the compost when turning it. If the turned material sticks to the blades and cannot be shaken off, it is too wet. Sprinkle a layer of dry straw on the compost before turning it again. The compost turner will automatically mix it during turning. If the material breaks down and becomes dusty when turned, it is too dry. Spray water on it while turning it, and control the moisture content so that it can be clumped when held in the hand but falls apart when released.
Third, don’t forget to turn the “edge piles.” Many people only turn the large pile in the center, neglecting the smaller piles on the sides, which can cause them to under-ferment. A windrow compost turner can move in a “U-shaped” pattern, turning the center first, then moving around to the edges, bringing the material toward the center, ensuring every pile is turned.

In modern agricultural production, fertilizer granulator is the key equipment to improve the utilization rate of fertilizer and meet the specific needs of crops. Choosing the right fertilizer granulator can not only improve the quality of fertilizer products, but also promote the healthy growth of crops. Here is a guide to choosing the right fertilizer granulation machine for your crop needs.
 

1. Crop demand analysis

 
First, it is necessary to analyze the characteristics of crop demand for fertilizer nutrients. The proportion and demand of main nutrients such as nitrogen, phosphorus and potassium are different in different crops. For example, leafy vegetables require more nitrogen fertilizer, while fruit trees require more phosphorus and potassium. Therefore, when choosing a fertilizer granulator, it should be considered whether it can meet the nutrient needs of specific crops.
 

2. Fertilizer Granulating Production Line

 
The fertilizer pelletizing line includes a variety of equipment, such as shredders, mixers, granulators, dryers and screeners. These devices work together to make the raw material into a granular fertilizer. When selecting, the integrity and synergy of the production line should be considered to ensure that the selected granulator can match the existing equipment to form an efficient production process.
 

3. Organic Fertilizer Production Line

 
For the Production of Organic Fertilizer, the Organic Fertilizer Production Line is key. Organic fertilizer is rich in organic matter and can improve soil structure and soil fertility. When selecting organic fertilizer granulator, it is necessary to consider its adaptability to organic raw materials, and whether it can produce uniform and high-quality granular fertilizer while maintaining the activity of organic matter.

4.Fertilizer Granules Compaction Machine

 
The Fertilizer Granules Compaction Machine is suitable for the production of high density granular fertilizers and is suitable for crops requiring high concentrations of fertilizers. This type of machine can compress fertilizer raw materials into particles through extrusion, improve the density and hardness of fertilizer, and reduce waste during application.

When choosing a fertilizer granulator, the following factors should also be considered:

 
Production scale: According to the production scale of the farm or fertilizer factory, choose the corresponding capacity of the granulator.
Cost-effectiveness: Considering the acquisition cost, operation cost and maintenance cost of the equipment, choose the cost-effective equipment.
Environmental impact: Choose environmentally friendly, low-energy equipment to reduce the impact on the environment during the production process.
Technical support and after-sales service: Select equipment suppliers with good technical support and after-sales service to ensure long-term stable operation of equipment.
 
To sum up, choosing the right fertilizer granulator requires comprehensive consideration of crop demand, production line supporting, equipment performance and economic factors. Through scientific and reasonable selection, the utilization efficiency of fertilizer can be improved, the healthy growth of crops can be promoted, and the sustainable development of agriculture can be achieved.

How Can Fertilizer Plants Reduce Costs And Improve Efficiency?

fertilizer granulator Oct 9, 2025

In an era of volatile raw material prices and intensified market competition, “cost reduction and efficiency improvement” has become a survival strategy for fertilizer manufacturers. Whether operating organic fertilizer production lines, optimizing nitrogen, phosphorus, and potassium fertilizer production lines, or expanding bio-organic fertilizer production, the key lies in intelligent upgrades, rational layout, and resource recycling—strategies that can transform operational pain points into profit drivers.

First, streamline production lines, reduce waste, and increase output. For example, one fertilizer company’s organic fertilizer production line previously suffered from significant raw material waste due to inconsistent decomposition. By integrating an intelligent temperature control system and automated crushing equipment, they reduced the waste rate from 15% to just 5%. Furthermore, the fermentation cycle was significantly shortened by 30%, directly reducing unit production costs. At ABC Fertilizer Company’s nitrogen, phosphorus, and potassium fertilizer production line, precision is key. They replaced manual batching with a state-of-the-art computer control system. This not only reduced nutrient deviation to within ±0.5% but also reduced labor costs by 35%. Furthermore, an upgrade to the granulator increased hourly output by 25%. Even bulk mixed fertilizer production lines, which require frequent recipe changes, can benefit from modular design. This fertilizer plant implemented this design, reducing downtime between batches by 50% and significantly improving equipment utilization.

Secondly, diversifying product lines can help balance market risks and increase revenue. A single organic fertilizer production line can struggle to cope with seasonal demand fluctuations. However, one fertilizer company decided to integrate it with bio-organic fertilizer production. This move opened doors to high-value markets such as organic farming and greenhouse cultivation, significantly expanding its customer base. Similarly, another fertilizer company integrated its NPK fertilizer production line with a bulk blended fertilizer line, offering a packaged combination of “basic NPK + customized blended fertilizer” for cash crops like strawberries and tomatoes. Data shows that, as in these success stories, plants with three or more complementary production lines are 50% more resilient than those operating a single line. Their average profit margins also increase by 8-12%. This synergy not only reduces raw material costs through bulk purchasing but also enables the reuse of by-products. For example, MNO Fertilizer Company uses fermentation residues from its organic fertilizer production line as an additive in its bio-organic fertilizer production, eliminating waste disposal fees.

Finally, energy conservation and recycling measures can be implemented to uncover hidden costs. This fertilizer company installed a waste heat recovery system in the drying process of its NPK fertilizer production line. This innovative measure successfully reused 70% of the waste heat, reducing fuel consumption by 20%. Meanwhile, in another fertilizer company’s organic fertilizer production line, biogas generated by fermentation now meets 40% of the plant’s electricity needs, significantly reducing utility bills. Implementing real-time energy monitoring is also crucial. They successfully identified and repaired a faulty pump in the bulk blended fertilizer production line that was consuming as much as 15% of the plant’s monthly electricity. This simple fix saved them over $20,000 annually.

For fertilizer plants, reducing costs and improving efficiency isn’t about cutting corners. Instead, it requires strategic investments in production lines, such as organic fertilizer and NPK, to leverage synergies and transform waste into value. By emulating these successful plants and focusing on these key areas, other fertilizer plants can not only withstand market fluctuations but also build sustainable long-term competitiveness.

How should a windrow compost turner be adjusted for different organic fertilizer raw materials?

fertilizer granulator Oct 9, 2025

Organic fertilizer raw materials vary greatly, such as straw, chicken manure, mushroom residue, and distiller’s grains, and their properties can vary greatly. When using a windrow compost turner, a few adjustments can ensure smoother fermentation.

If you’re turning dry straw, it’s fluffy and porous, but it’s prone to “lifting.” The blades of a windrow compost turner tend to only scrape the surface, failing to thoroughly turn the bottom. In this case, you can steepen the blade angle to allow it to penetrate deeper into the pile. At the same time, slow down the compost turner’s speed to 2-3 kilometers per hour. This ensures that both the top and bottom of the straw pile are turned loosely, breaking up any large clumps and facilitating subsequent fermentation.

If you’re turning wet, sticky raw materials like chicken manure and pig manure, they tend to clump and stick to the blades, and the pile may become compacted after turning. At this time, the blade angle should be adjusted to a gentler angle to reduce sticking, and the forward speed can be increased slightly to allow the turned manure pile to quickly disperse and breathe. Additionally, before turning the pile, sprinkle some dry sawdust on the surface. This will automatically mix the material as the compost turner turns, reducing moisture and preventing clumping.

When turning fine ingredients like mushroom residue and distiller’s grains, the main concern is “missing” them. If the pile is too loose, they can easily leak through the gaps between the blades. By reducing the blade spacing on the windrow compost turner and maintaining a moderate speed, the fine ingredients can be turned over, ensuring even mixing and accelerating fermentation by about 10 days.

Discover how modern organic fertilizer production lines transform agricultural waste into efficient nutrient granules through precision processes, opening a new chapter in sustainable agriculture

The Magical Transformation: From Waste to Nutrient Granules

Have you ever imagined how discarded livestock manure, crop straw, and food processing residues could undergo a magnificent transformation into valuable resources that nourish the land? This is not just resource recycling, but the wonderful art of modern organic fertilizer production. The entire organic fertilizer production process resembles a carefully orchestrated symphony, where each step plays an indispensable role.

The Carefully Prepared Overture: Raw Material Pre-treatment

1 – Intelligent Collection and Classification

The organic fertilizer production journey begins with precise raw material collection. Like treasure hunters, we gather various organic wastes from farms, food processing plants, and other sources, conducting scientific classification. This meticulous sorting not only lays the foundation for subsequent processing but also ensures the stability of raw material quality.

2 – Precision Crushing and Mixing

Using advanced crushing equipment, we process large raw materials into ideal particle sizes suitable for fermentation. Subsequently, materials are mixed according to scientific ratios to optimize the carbon-nitrogen ratio, much like preparing a “nutritious feast” for microorganisms, creating optimal conditions for efficient fermentation.

The Metamorphosis of Life: The Art of Fermentation

3 – The Magic of Compost Fermentation

Within carefully designed fermentation areas, raw materials begin their miraculous transformation under microbial action. Whether through natural fermentation or artificially controlled heating processes, pathogens and weed seeds are silently eliminated while complex organic matter is broken down into forms easily absorbed by plants.

4 – Precision Process Control

Through real-time monitoring of temperature, humidity, and oxygen levels, we carefully regulate the fermentation environment like attentive gardeners. Regular turning not only provides sufficient oxygen but ensures every part of the raw material ferments uniformly – this is key to guaranteeing product quality.

The Essence of Granulation: From Powder to Perfect Granules

After fermentation, materials undergo further screening and crushing to remove undecomposed impurities, then enter the most exciting phase of the entire organic fertilizer production process – granulation. In advanced organic fertilizer granulators, powdered raw materials gradually take shape under precise control, transforming into uniform granules. This transformation not only significantly enhances the product’s commercial value but makes fertilizer storage, transportation, and application exceptionally convenient.

Modern organic fertilizer production lines are equipped with complete post-processing systems: drying processes remove excess moisture to prevent caking; cooling ensures appropriate product temperature; fine screening guarantees uniform particle size; optional coating processes can form protective layers on granule surfaces, achieving controlled nutrient release effects.

The Perfect Finish: Quality Assurance and Storage

5 – Intelligent Packaging and Quality Inspection

Automatic packaging machines precisely complete weighing and packaging, with each bag carrying a commitment to quality. Strict quality testing ensures products meet relevant standards – from nutritional content to physical characteristics, no detail is overlooked.

Practical Methods for Improving the Granulation Yield of Flat Die Granulators

fertilizer granulator Sep 30, 2025

In organic fertilizer production lines, flat die granulators typically process materials such as livestock and poultry manure and composted straw. These materials contain coarse fiber and experience large moisture fluctuations, which can easily lead to low granulation yields and loose pellets. To improve granulation efficiency, precise optimization in four key areas is necessary, taking into account the characteristics of the organic fertilizer material.

Raw material pretreatment must be tailored to the characteristics of the organic fertilizer. First, the moisture content should be controlled between 25% and 30%, which is the optimal range for organic fertilizer granulation. A moisture content too low can easily result in broken pellets, while a moisture content too high can cause die sticking and clogging. This can be adjusted by airing the material or adding dry straw powder. Secondly, the composted material should be pulverized to ensure that the coarse fiber particle size does not exceed 1/2 the die hole diameter to prevent fibers from wrapping around the die rollers and causing uneven extrusion. Uncomposted lumps should also be removed to prevent clogging. Additionally, 2% to 3% bentonite can be added as a binder to enhance pellet density without affecting the fertilizer’s efficiency.

Equipment adjustments require targeted optimization. Organic fertilizer materials have poor fluidity, so the die roller gap should be adjusted to 0.2-0.4mm, slightly wider than the standard setting, to prevent material from getting stuck. The roller speed should be reduced to 15-20r/min to allow ample time for the coarse fibers to be extruded and formed. For die orifice selection, a tapered die with a diameter of 4-8mm is preferred to reduce material resistance within the die and minimize the likelihood of blockage. Regularly clean the die orifice with a steel brush to remove residual fiber impurities.

Process operations should be tailored to the production scenario. High-temperature preheating is not required before startup. Simply use a small amount of wet material to “prime” the die, forming a thin layer of material on the inner wall of the die orifice to prevent subsequent material from sticking to the wall. Use a spiral feeder with a constant speed to avoid concentrated lumps of material and prevent equipment overload. If fibers are found on the surface of the pellets and they are prone to breakage during production, add binder or adjust the moisture content promptly.

Maintenance should focus on vulnerable areas. Organic fertilizer materials contain corrosive components. The die roller surface should be cleaned weekly, and residual humus should be removed with a wire brush to prevent corrosion. The inner wall of the die hole should be inspected monthly, and burrs caused by coarse fiber wear should be removed with fine sandpaper. The transmission system lubricant should be replaced quarterly, using a corrosion-resistant, specialized oil to prevent component wear caused by humus contamination.

By optimizing these measures for organic fertilizer production lines, the flat die granulator’s pelletizing rate can be increased to over 90%, reducing waste of mature raw materials while ensuring uniform organic fertilizer pellets and ensuring stable and efficient production line operation.

Solutions to Production Difficulties in Bio-Organic Fertilizer Production Lines

fertilizer granulator Sep 30, 2025

Bio-organic fertilizer production lines often encounter challenges in raw materials, fermentation, equipment operation, and quality control. Through targeted, simple measures and process optimization, bottlenecks can be effectively overcome, ensuring stable production.

The core challenges of raw material pretreatment are uneven composition and excessive impurities. A “stratified sampling + manual blending” approach can be adopted: raw materials are sampled strata by stacking area. Moisture content is measured using a drying method (the sample is dried and then weighed to calculate moisture). The auxiliary materials are then mixed based on experience. If feces is wet and sticky, add pulverized straw at a ratio of 10:3; if it is dry, add an appropriate amount of water. Furthermore, workers are assigned to sort impurities such as plastic and stone from the raw materials. A small magnetic separator (low-cost and easy to operate) is used to remove metallic foreign matter. Samples from each batch of raw materials are sent to a third party for testing for heavy metals and antibiotics, mitigating risks at the source.

The difficulty in controlling temperature and humidity during fermentation, as well as exhaust gas pollution, can be addressed through “manual monitoring + process optimization.” Dedicated personnel are assigned to monitor different points in the stack with thermometers and hygrometers every morning, noon, and evening. A two-step process of “high-temperature composting + low-temperature aging” is employed: the high-temperature period (55-65°C) lasts approximately eight days, with the compost turned every two days to kill pathogens. During the low-temperature period (25-35°C), the materials are moved to a cool, shaded area and covered with film to insulate and promote the growth of beneficial bacteria. To address waste gas emissions, a shallow pond is dug next to the fermentation workshop and filled with a mixture of straw and soil. This is used to direct the waste gas into the pond for absorption and odor reduction.

Issue of unstable equipment operation and disconnected quality control can be addressed through “equipment fine-tuning + manual spot checks.” The crusher’s screen is changed based on the hardness of the raw material (a fine-mesh screen is used for higher hardness), and the feed rate is manually controlled to ensure that the crushed material passes through a 20-mesh screen. The granulator‘s heating knob is manually adjusted, and the temperature is gradually adjusted during pilot production until the pellets are non-sticky and non-fragile. For quality control, samples are taken daily during the fermentation stage to measure organic matter using the incineration method (weight loss after incineration is calculated). pH test paper is used to measure pH after granulation. Finished products are sampled and tested by batch, avoiding quality control vulnerabilities that can arise from reliance on complex equipment.

These methods are simple to operate and low-cost, effectively addressing challenges in bio-organic fertilizer production lines and helping small and medium-sized bio-organic fertilizer manufacturers improve product quality and production efficiency.

Organic Fertilizer Production Line Risk Response Plan

fertilizer granulator Sep 30, 2025

As a key component of the agricultural circular economy, the stable operation of the organic fertilizer production line directly impacts agricultural product quality and environmental safety. This contingency plan has been developed to effectively address various risks in the production process and ensure continuous and efficient operation of the production line.

Raw material supply risk is the primary challenge facing the production line. Organic fertilizer raw materials are primarily agricultural waste, such as livestock and poultry manure and straw. These are susceptible to seasonal fluctuations, epidemics, and other factors, leading to supply disruptions or substandard quality. To address this, it is necessary to establish records for at least three raw material suppliers, sign long-term supply agreements, clearly define raw material quality standards, and establish an emergency replenishment mechanism. Furthermore, a raw material storage area with a capacity of at least 15 days should be reserved within the plant, equipped with rainproof and anti-seepage facilities to prevent mold and loss of raw materials.

Equipment failure directly impacts production schedules. Sudden failure of core equipment in the organic fertilizer production line, such as the fermentation turner, granulator, and dryer, will result in a complete shutdown. A regular equipment inspection system should be established, with daily checks on the operating status of key components and weekly comprehensive maintenance. A spare parts warehouse should be established to stockpile vulnerable parts such as motors and bearings, ensuring replacement within two hours of a malfunction. Emergency maintenance agreements should be signed with equipment manufacturers, promising on-site response within 48 hours for major malfunctions.

Production safety risks cannot be ignored. The fermentation process of raw materials may produce flammable and explosive gases such as methane, and the drying process presents a fire hazard. Combustible gas detectors and alarms should be installed in the fermentation workshop, and automatic fire extinguishing systems should be installed in the drying section. Regular fire safety training and emergency drills should be conducted to ensure that every operator is proficient in the use of fire extinguishing equipment. A strict hot work approval system should be implemented, and supervisors and fire extinguishing equipment must be present on-site.

Furthermore, external risks such as market fluctuations and policy adjustments must be addressed. Diversified product sales channels should be established, and changes in agricultural subsidy policies should be closely monitored to adjust production plans in a timely manner. By establishing a comprehensive risk prevention and control system, the impact of various risks on organic fertilizer production lines can be effectively reduced, ensuring the stability of the green agricultural development industry chain.

Key Processes and Practices for Granular Fertilizer Production from NPK Raw Materials

fertilizer granulator Sep 30, 2025

Converting elemental nitrogen, phosphorus, and potassium raw materials into granular fertilizer requires scientific proportioning, physical shaping, and precise control to achieve balanced nutrients and convenient application. This npk fertilizer production line not only improves fertilizer utilization but also addresses the challenges of bulk raw materials, such as clumping and transportation difficulties.

The first step is raw material pretreatment and proportioning. Nitrogen sources (such as urea and ammonium chloride), phosphorus sources (superphosphate and diammonium phosphate), and potassium sources (potassium chloride and potassium sulfate) must be crushed to a fineness of 80-100 mesh to ensure uniform mixing. The nitrogen, phosphorus, and potassium ratios are precisely adjusted based on the needs of the target crop. For example, the 15-15-15 general formula commonly used for field crops requires strict control of the tolerance of each raw material within ±0.5%. 5%-8% bentonite is added as a binder to enhance granularity.

The core granulation process often utilizes a rotary drum granulation process. The mixed raw materials are fed into a rotary drum granulator, where a 30%-40% solution of warm water or dilute phosphoric acid is sprayed through a spray device to form “mother balls” within the drum. The drum speed is controlled at 20-25 rpm, and the inclination angle is maintained at 3°-5°. This ensures that the mother balls continuously absorb the raw material powder as they rotate, gradually growing into uniform granules with a diameter of 2-4mm. For the production of high-concentration granular fertilizers, an extrusion granulation process is used. A twin-screw extruder presses the material into a cylindrical shape, which is then sheared into granules by a pelletizer. This is suitable for formulas with low moisture content.

After granulation, the granules undergo drying and cooling. The temperature in the drum fertilizer dryer is controlled at 120-150°C to reduce the moisture content of the granules to below 10% to prevent clumping during storage. The granules then enter a drum fertilizer cooler, where low-temperature air is used to cool them to room temperature to prevent condensation during subsequent packaging. Finally, unqualified granules (overly coarse or fine) are separated by a screening machine and returned to the granulator for reprocessing. The finished product is then sprayed with an anti-caking agent in a coating machine to improve storage stability.

Throughout the entire production process, indicators such as granule strength (should be ≥20N) and disintegration (disintegrates in water within 30 minutes) are monitored in real time to ensure product compliance with national standards. This process transforms nitrogen, phosphorus, and potassium raw materials from bulk to granules, facilitating mechanized fertilization while reducing nutrient loss, providing strong support for improving agricultural quality and efficiency.
