How can you use new type organic fertilizer granulators more efficiently and save energy and materials?

fertilizer granulator Oct 9, 2025

Many organic fertilizer plants are concerned about costs. However, when using new type organic fertilizer granulators, paying attention to two small details can significantly save energy and materials.

To save energy, most new type organic fertilizer granulators are equipped with variable-frequency motors. Avoid running them at maximum speed all the time. For example, when initially feeding, use a low speed of 15 rpm. Once the raw materials have stabilized in the granulation chamber, gradually increase the speed to 20-25 rpm. This prevents the motor from exerting sudden force, saving 10%-15% of energy per hour. Additionally, avoid idling the machine. Do not start the machine until the raw materials are ready. The energy wasted in idling for one hour is enough to generate granules for 20 minutes.

To save materials, the key is to reduce waste. New type organic fertilizer granulators have a return device. Instead of discarding the crushed granules, they are directly returned to the granulation chamber through the return port, where they are mixed with new raw materials and granulated again. This can reduce the waste rate from 10% to less than 3%. Also, do not mix impurities such as stones and iron wire into the raw materials. Impurities will wear out machine parts and crush good particles. Use a sieve before feeding each time to avoid a lot of material waste.

Benefits of Using a Flat Die Granulator in an Organic Fertilizer Production Line

In organic fertilizer production, the granulator is a core piece of equipment that determines product quality and production efficiency. The flat die granulator, with its unique design, is the preferred equipment for organic fertilizer production lines. Its advantages are primarily reflected in five key areas.

First, it offers excellent adaptability to raw materials. Organic fertilizer raw materials are complex, with common materials like livestock and poultry manure, straw, and mushroom residue exhibiting widely varying moisture and fiber content. By adjusting the pressure of the rollers and the speed of the die, the flat die granulator can easily process raw materials with a moisture content of 15%-30%. This eliminates the need for over-drying or the addition of large amounts of binders, preserving the beneficial microorganisms in the raw materials while reducing pretreatment costs. This makes it particularly suitable for the diverse raw material production needs of small and medium-sized organic fertilizer plants.

Second, the granulation quality is stable and controllable. The flat die granulator utilizes a “fixed die plate, rotating pressure roller” extrusion granulation method, achieving a pellet forming rate exceeding 95%. Pellet diameter can be flexibly adjusted (typically between 2 and 12 mm) by replacing dies with different apertures, meeting the pellet specification requirements for various applications, such as seedling fertilizer and field fertilizer. The pellets have a moderate hardness and are resistant to breakage, making them easy to package, transport, and spread in the field, effectively enhancing the product’s market competitiveness.

Furthermore, they offer low energy consumption and operating costs. Compared to ring die granulators, flat die pelletizers utilize a lower motor power, reducing power consumption by 20%-30% at the same production capacity. Furthermore, their consumable parts (such as the pressure roller and die) are made of wear-resistant alloy, offering a service life of over 3,000 hours. Replacement frequency is low, and the cost of spare parts is only half that of ring die pelletizers, significantly reducing production line operating expenses over the long term.

Furthermore, they are easy to operate and maintain. The flat die granulator boasts a simple and compact structure, a small footprint, and a quick installation and commissioning cycle. Operators can easily master the machine after minimal training. Routine maintenance requires only the regular addition of lubricating oil and cleaning of residual material from the die holes, eliminating the need for complex technical expertise. This significantly reduces labor costs and is particularly suitable for small and medium-sized manufacturers facing a shortage of skilled personnel.

Overall, the flat die granulator, with its high adaptability, cost-effectiveness, and ease of operation, is an ideal choice for improving efficiency, reducing costs, and ensuring quality in organic fertilizer production lines. It provides strong support for the development of small and medium-sized organic fertilizer manufacturers.

The Difference Between Organic Fertilizer Production Lines and Bio-Organic Fertilizer Production Lines

fertilizer granulator Oct 9, 2025

While both organic fertilizers fall under the category of green fertilizers, their production lines differ significantly in terms of technical logic, process design, and product positioning. These differences directly determine the fertilizer’s function and application scenarios. Specifically, they can be distinguished in four key areas:

First, there are core definitions and raw material differences. Organic fertilizer production lines use agricultural or domestic organic waste, such as livestock and poultry manure, straw, and food waste, as raw materials. They achieve “reduction and harmlessness” through natural composting, eliminating the need for the addition of functional bacteria. Bio-organic fertilizer production lines, on the other hand, require the precise incorporation of specific functional microorganisms (such as Bacillus and Trichoderma) into the raw materials. The raw materials must also be selected with highly active carriers (such as soybean meal and humic acid) to provide nutrients for bacterial growth. The core goal is to leverage microbial activity to enhance fertilizer efficacy.

Second, there are key process differences. Organic fertilizer production lines rely on naturally occurring microorganisms for fermentation, resulting in large temperature fluctuations (typically 40-60°C) and a long composting cycle (1-2 months). Further processing primarily involves crushing and granulation, requiring no specialized temperature control. Bio-organic fertilizer production lines, on the other hand, require an additional “strain inoculation” step. During the fermentation phase, an intelligent temperature control system maintains a stable temperature of 55-65°C to ensure the raw materials are fully composted while preventing high temperatures from killing the functional bacteria. Subsequent low-temperature drying (≤60°C) is required to ensure the viable bacterial count in the finished product meets the national standard of ≥200 million/g. This process requires greater complexity and precision.

Secondly, there are differences in product characteristics. The core value of organic fertilizer products is to replenish soil organic matter and improve soil physical structure. They release nutrients slowly but lack specific functional properties. Bio-organic fertilizers, in addition to replenishing organic matter, also utilize functional bacteria to achieve specific benefits. For example, phosphate and potassium-solubilizing bacteria activate soil nutrients, while disease-resistant bacteria inhibit soil-borne diseases. Products must be labeled with the strain type and viable bacterial count, and quality standards are more stringent.

Finally, there are differences in application scenarios. Organic fertilizer has a wide range of applications. It can be used as base fertilizer for field crops and to improve poor soil. Bio-organic fertilizer is more suitable for cash crops (such as vegetables and fruit trees) or facility agriculture. It can specifically solve soil continuous cropping problems and improve the quality of agricultural products. It is more widely used in green agriculture and organic farming.

Key Considerations for Composting in Organic Fertilizer Production Lines

fertilizer granulator Oct 9, 2025

In organic fertilizer production lines, composting is a core step that determines the quality of organic fertilizer. Improper operation not only reduces fertilizer efficiency but can also lead to odor, pathogens, and other issues, impacting production efficiency and the environment. The following are key considerations during composting:

First, the raw material ratio must be scientifically and accurately formulated. Composting raw materials typically consist of livestock and poultry manure, straw, and mushroom residue. The carbon-nitrogen ratio (C/N) must be strictly controlled between 25:1 and 35:1. A high C/N ratio will slow composting and easily lead to a “cold pile.” A low C/N ratio will result in nitrogen loss and produce foul odors. Furthermore, the moisture content of the raw materials must be adjusted to 50%-60%. Hold the raw materials tightly with your fingers until water is present but not dripping. Excessive moisture can easily lead to anaerobic fermentation, while too low a moisture content can inhibit microbial activity.

Second, compost management requires dynamic monitoring. The recommended height of the compost pile is 1.2-1.5 meters, and the width is 2-3 meters. The length should be adjusted according to the scale of the organic fertilizer production line. Excessively high or wide compost piles will result in poor ventilation, while excessively low compost piles will dissipate heat too quickly, making it difficult to maintain a high temperature. During the composting process, the compost should be turned regularly. Typically, the compost temperature should rise above 60°C for 2-3 days before being turned using a compost turner. This not only replenishes oxygen but also maintains a uniform temperature throughout the compost, helping to inactivate pathogens and weed seeds. The frequency of turning should be adjusted based on temperature fluctuations, generally once or twice a week.

Finally, environmental conditions must be strictly controlled. The composting room must maintain good ventilation to prevent the accumulation of harmful gases. Rain protection measures should also be implemented to prevent nutrient loss and water accumulation due to rainwater erosion. Furthermore, compost temperature and pH should be monitored in real time. During normal composting, the compost temperature should rise first, then fall, ultimately stabilizing at room temperature, with the pH maintained between 7.5 and 8.5. If abnormalities are detected, the raw material ratio or the turning frequency should be adjusted promptly. Only by strictly following these precautions can we ensure an efficient and stable composting process, produce high-quality organic fertilizer that meets standards, and provide strong support for the green development of agriculture.

The Proportioning Process of an NPK Fertilizer Production Line

fertilizer granulator Oct 9, 2025

In an NPK fertilizer production line, the proportioning process is the key step in determining fertilizer quality and effectiveness. By precisely controlling the ratios of nitrogen (N), phosphorus (P), potassium (K), and trace elements, it adapts fertilizer to the needs of different crops, soils, and growth stages, directly impacting agricultural production yield and quality.

The proportioning process must adhere to the principle of “customization on demand.” Nutrient requirements vary significantly among crops: rice requires high nitrogen to promote tillering, so the nitrogen content in the proportion is often 20%-25%; fruit trees require high potassium to enhance sweetness during the fruit-bearing stage, so the potassium ratio should be adjusted to 15%-20%; vegetables require a balanced ratio of nitrogen, phosphorus, and potassium, typically maintaining a ratio of approximately 1:1:1. Soil conditions also influence the proportioning process. Acidic soils require reduced phosphorus application to prevent fixation, while saline-alkali soils require increased nitrogen to compensate for leaching losses.

Precise proportioning relies on advanced technology. Modern production lines often utilize “automatic batching systems.” Sensors monitor the moisture and particle size of raw materials in real time, and combined with a PLC control system, they automatically adjust the feed rate with an error controllable within ±0.5%. For example, for wheat fertilizer, the system automatically delivers urea, monoammonium phosphate, and potassium chloride to the mixer in the corresponding proportions according to an “18-12-15” formula, ensuring consistent nutrient content in each batch.

The batching process must also balance environmental protection and efficiency. Improper batching can lead to nutrient waste: excessive nitrogen content can easily lead to eutrophication, while excessive phosphorus can cause soil compaction. Therefore, production lines incorporate “nutrient balance algorithms” to optimize the batch based on regional soil testing data, minimizing nutrient loss while meeting crop needs. Furthermore, pre-mixing disperses insoluble raw materials, preventing localized nutrient excess or deficiency caused by uneven batching.

As the core link of the NPK fertilizer production line, scientific ratio is not only the key to improving fertilizer competitiveness, but also an important guarantee for helping agriculture “reduce weight and increase efficiency” and achieve green production.

Even in small spaces! Flexible placement tips for windrow compost turning machines

fertilizer granulator Oct 9, 2025

Many small organic fertilizer plants worry about “small space and compost turning machine maneuvers.” In fact, as long as you master placement and routing techniques, a windrow compost turning machine can operate smoothly even in a space as small as 100 square meters.

First, the pile must be placed smoothly. Avoid stacking the pile in small, scattered, round piles. Instead, create long, narrow piles—for example, a 1-meter-wide, 1.2-meter-high, and 5-meter-long strip. This allows the compost turner to move along the strip in a straight line, eliminating the need for frequent turns. This saves space and ensures thorough turning. Leave a 1.5-meter-wide aisle between two long piles—just enough for the compost turner to move back and forth without hitting the adjacent piles.

Second, turning techniques are crucial. If the space is truly limited and the windrow compost turning machine needs to turn, don’t do it directly on the pile; instead, move it into the aisle. First, raise the compost turner’s blades and move it to the center of the aisle. Then, slowly turn (keeping the turning radius at least 2 meters) to avoid the tracks pressing into the pile and causing the material to clump.

Also, you can turn the compost in layers. If the pile is high (over 1.5 meters) and the site is not wide enough, the windrow compost turning machine can turn the material on the top layer first, loosening it, and then lower the blades to turn the lower layers. This allows for thorough turning without breaking up the pile.

Why choose a disc granulator for granulation?

fertilizer granulator Oct 9, 2025

Disc granulators have always held a crucial position in granulation production in industries such as fertilizer, metallurgy, and building materials, becoming the preferred equipment for many companies. They offer numerous irreplaceable advantages.

In terms of granulation performance, disc granulators are considered “precision granulation experts.” The rotating disc drives the material in a circular motion. The combined effects of centrifugal force, gravity, and friction evenly coat the material with water or binder, resulting in a finished product with uniform size and high roundness. Compared to other granulation equipment, disc granulators produce granules with moderate strength and resistance to breakage. These granules maintain excellent condition during subsequent storage, transportation, and use, effectively improving product quality and market competitiveness.

Another key advantage of disc granulators is their ease of operation. With a simple structure consisting solely of a rotating disc and transmission mechanism, routine operation requires no complex technical skills and can be mastered by workers after a short training period. Furthermore, its operation is stable, with a low failure rate. Even if minor issues do occur, repairs are relatively simple, significantly reducing downtime, ensuring continuous and efficient production, and minimizing losses caused by equipment failure.

Disc granulators also offer significant advantages in terms of cost and energy consumption. Their relatively low manufacturing cost allows small and medium-sized enterprises to install advanced granulation equipment without a high investment. Furthermore, their low energy consumption during operation significantly reduces electricity, fuel, and other energy consumption compared to other granulation equipment with the same production capacity. Long-term use can help companies reduce production costs and increase profitability.

Disc granulators are also widely applicable, effectively adapting to fertilizer production lines such as organic fertilizer and compound fertilizer, as well as granulating industrial materials such as ore powder and coal powder. This “one machine, multiple uses” feature eliminates the need for companies to purchase separate equipment for different materials, further reducing equipment investment and improving resource utilization.

With its outstanding comprehensive performance, disc granulators are an ideal choice for granulation production, helping various industries achieve high-quality and efficient granulation operations.

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.
