fertilizer granulator Nov 3, 2025

As the organic fertilizer industry transforms towards high efficiency and green practices, the new type organic fertilizer granulator has developed unique advantages over traditional equipment through technological upgrades. It addresses the pain points of traditional granulators while meeting the demands of modern production and the market.

1.Versatile Raw Material Compatibility

The granulator is compatible with not only conventional raw materials such as livestock manure and straw, but also efficiently processes high-fiber (oil palm empty fruit bunch, mushroom residue) and high-moisture (30%-40%) raw materials that are difficult to form. Optimized extrusion structure and die design prevent blockages caused by fiber entanglement and material adhesion.

2.Low Energy Consumption and Environmental Protection

The new type organic fertilizer granulator uses an energy-saving motor and optimized transmission structure, resulting in low energy consumption. Simultaneously, the fully enclosed design, coupled with a dust recovery device, keeps dust generation during the granulation process to extremely low levels, reducing the impact on the workshop environment and operators.

3.Intelligent and Precise Parameter Control

The granulator incorporates a simple intelligent control system that automatically adjusts parameters such as roller pressure and speed based on raw material characteristics (humidity, particle size, viscosity). This eliminates the need for frequent manual adjustments, ensuring stable production of uniform granules with the required hardness.

4.Improved Granule Quality and Production Efficiency

By optimizing the contact method between the rollers and the die, the new type organic fertilizer granulator increases the material forming rate, reducing raw material waste. The formed granules are not only dense and less prone to breakage, but also form a uniform porous structure, facilitating the slow release of nutrients. Simultaneously, the equipment’s anti-clogging design and easy-to-clean structure reduce downtime for maintenance.

Flat die pelleting machine: Protecting the activity of microbial agents in low-temperature granulation

The core challenge in biofertilizer production lies in ensuring that the granulation process does not destroy the activity of the microbial agent. Most functional bacteria (such as Bacillus subtilis and Trichoderma harzianum) are significantly inactivated at temperatures above 45°C. The flat die pelleting machine, with its low-temperature granulation capabilities, is a suitable choice for biofertilizer production. Its core advantage lies in its low-friction, no-additional-heat granulation process.

The flat die pelleting machine utilizes a vertical extrusion process, with the rollers and the die in contact with each other over a surface area rather than at points. This results in more uniform force per unit area, less frictional heat generation, and a temperature within the granulation chamber typically maintained at 35-40°C, well below the inactivation threshold of the microbial agent.

Furthermore, the machine does not rely on high-temperature conditioning or hot air conditioning; instead, it achieves granulation solely through the viscosity of the raw material and moderate extrusion, eliminating the need for additional heat input.

Furthermore, the flat die granulator’s speed is adjustable (typically 30-50 rpm). For biofertilizer raw materials with high microbial content, the speed can be reduced to below 30 rpm to further reduce frictional heat generation and ensure a microbial survival rate above 85%.

In practical applications, it is even more effective when used with a “room-temperature binder.” This eliminates the need for heating and dissolving the pellets, while also improving the pelletizing efficiency and complementing the flat die pelleting machine‘s low-temperature characteristics. This ensures the biofertilizer’s core function (microbial activity) while producing uniform pellets, meeting the dual requirements of “functionality” and “commerciality.”

As a key carrier for ensuring product quality, bio-organic fertilizer equipment is designed and functions around the core needs of bio-organic fertilizer: “preserving activity, promoting composting, and ease of application.”

1.Strong Activity Protection Orientation

The core value of bio-organic fertilizer lies in the activity of beneficial microorganisms. The equipment avoids high-temperature damage throughout the entire process. In the fermentation stage, precise temperature control through a compost turning machine and fermentation tank satisfies both sterilization and composting requirements while preventing microbial inactivation. Granulation employs a low-temperature extrusion process, and cooling equipment quickly lowers the material to room temperature, reducing damage to the microbial community from high temperatures.

2.Controllable Composting Process

The equipment achieves precise control of fermentation conditions through mechanical design: the compost turning machine can adjust the turning frequency to ensure sufficient oxygen in the pile; the fermentation tank adopts a closed design, monitoring and adjusting temperature, humidity, and oxygen content in real time, shortening the composting cycle while ensuring uniform material composting and reducing odor emissions.

3.Wide Range of Raw Material Compatibility

The bio-organic fertilizer equipment is highly adaptable to various organic raw materials such as poultry and livestock manure, straw, mushroom residue, and distiller’s grains. The crushing equipment can adjust the particle size according to the hardness of the raw materials; the mixing equipment can evenly blend raw materials with different moisture content and specific gravity to ensure precise carbon-to-nitrogen ratio.

4.High Modularity and Flexibility

The equipment adopts a modular design, allowing for flexible combinations based on production scale. Small production lines can be equipped with simple compost turners and manual packaging equipment to reduce investment costs; large-scale production can be configured with automated fermenters and continuous granulation units to improve production efficiency.

Under the trend of green agricultural development, the bio-organic fertilizer production line, with its unique technological advantages, has become a key piece of equipment driving the transformation and upgrading of the fertilizer industry.

The production line’s technical core lies in three dimensions: First, a precise batching system. Automated equipment precisely controls the ratio of raw materials and inoculants, ensuring stable microbial activity and balanced nutrient distribution. Second, intelligent fermentation control. Sensors monitor the compost temperature, humidity, and oxygen content in real time, automatically adjusting the turning frequency and ventilation rate of the compost turning machine to shorten the fermentation cycle and improve compost maturity. Third, low-temperature post-processing technology utilizes a 60-80°C drying process to prevent high temperatures from damaging microbial activity and organic matter structure, thereby maximizing the nutrient value of the fertilizer.

From an industry perspective, the bio-organic fertilizer production line offers multiple benefits: For the livestock industry, it effectively disposes of waste such as livestock and poultry manure, addressing environmental concerns. For agricultural production, the bio-organic fertilizer produced improves soil compaction and fertility, reducing reliance on chemical fertilizers and promoting improved crop quality and efficiency. For the ecological environment, the fully closed-loop production process reduces pollutant emissions and promotes the recycling of agricultural waste.

The journey from organic waste to high-efficiency fertilizer

The bio-organic fertilizer production line utilizes organic waste such as livestock and poultry manure, straw, and mushroom residue as raw materials. Through microbial fermentation technology, it recycles resources and produces fertilizer rich in active bacteria and organic matter. Bio-organic fertilizer production lines serve as a vital link between the livestock and poultry industry, the agricultural industry, and the environmental protection industry.

Raw material pretreatment is a fundamental step. It requires crushing and screening the organic waste to remove impurities and ensure a uniform particle size (approximately 80 mesh). Auxiliary materials are then added to adjust the carbon-nitrogen ratio (25-30:1) and humidity (55%-65%) to create a suitable environment for microbial growth. This phase then enters the inoculation and fermentation stage, where specialized microbial agents are added to the mixture. A compost turning machine regularly turns the compost to provide oxygen, maintaining a temperature of 55-65°C. Composting continues for 20-30 days, effectively killing pathogens and insect eggs and breaking down large organic molecules.

The fermented material undergoes post-processing to optimize quality. First, it undergoes low-temperature drying to reduce moisture to below 12% to prevent mold and mildew during storage. It then undergoes crushing, screening, and grading, with unqualified particles returned to the pre-processing stage for recycling. Finally, functional microbial agents can be optionally added to the mix to enhance the bioactivity of the fertilizer, depending on crop needs. The resulting pellets are uniform and rich in humic acid, amino acids, and a variety of beneficial bacteria, providing nutrients for crops while also improving the soil microbial ecosystem.

Windrow compost turning machines offer a standardized, complete process for recycling chicken manure

fertilizer granulator Oct 29, 2025

Chicken manure, a common waste product in the livestock industry, is rich in nitrogen, phosphorus, potassium, and organic matter. However, its direct use without treatment can easily cause soil contamination and crop burn. The windrow compost turning machine uses a scientific processing process to transform chicken manure into high-quality organic fertilizer, effectively recycling pollutants.

The first step is raw material pretreatment. Fresh chicken manure has a moisture content of approximately 60%-70% and a low carbon-nitrogen ratio. Straw, sawdust, and other auxiliary materials are added proportionally to adjust the carbon-nitrogen ratio to 25-30:1, and the humidity is controlled at 55%-65% to create a suitable environment for aerobic microbial fermentation. After mixing, a loose pile is formed.

The second step is pile construction and initial fermentation. The mixed material is piled into a long, 3-5 meter wide and 1-1.5 meter high pile. The windrow compost turning machine, with its crawler tracks, can operate directly on the soft pile, avoiding sinking. After the equipment is started, the turning gears penetrate deep into the pile, thoroughly mixing the bottom and top layers. Air is introduced simultaneously, promoting the growth of aerobic microorganisms and rapidly raising the pile temperature to above 55°C.

The third step is continuous turning and temperature control. During the fermentation period, the compost turner operates at a set frequency: once daily in the early stages and every other day in the later stages. This turning process not only replenishes oxygen and removes fermentation waste gases, but also stabilizes the pile temperature at 55-65°C. This temperature effectively kills harmful substances such as E. coli and roundworm eggs in the chicken manure, while also accelerating the decomposition and conversion of organic matter.

The entire processing cycle takes approximately 25-35 days. After being processed by the windrow compost turner, the chicken manure is transformed from sticky, foul-smelling waste into a loose, odorless, and mature material. It can then be crushed and screened to produce organic fertilizer.

Windrow compost turning machine: Efficient equipment for converting livestock manure into organic fertilizer

In the resource utilization of livestock and poultry waste, windrow compost turning machines, with their flexible and efficient operation, have become a core piece of equipment for converting livestock manure into organic fertilizer. Through mechanized turning and plowing, they accelerate manure composting and fermentation, transforming livestock pollutants into high-quality organic fertilizer, addressing environmental challenges while also promoting resource recycling.

The core advantage of windrow compost turning machines lies in their adaptability. Their crawler-type design allows for free movement in muddy composting areas. The large ground contact area and low pressure prevent them from sinking into the manure pile, making them suitable for various sizes of fermentation workshops or open-air sites. Equipped with a hydraulically driven turning gear shaft, the equipment can reach a turning depth of 0.8-1.5 meters, thoroughly mixing the bottom layer of manure with the surface material, breaking up compacted materials and ensuring uniform fermentation.

In the livestock manure processing process, windrow compost turners play a key role in promoting fermentation. First, livestock manure is mixed with supplementary materials such as straw and sawdust in appropriate proportions, adjusting the carbon-nitrogen ratio to 25-30:1 and the humidity to 55%-65% to create optimal conditions for microbial fermentation.

Subsequently, a compost turning machine regularly turns the pile, introducing sufficient oxygen to support aerobic microbial activity and rapidly dissipating the heat generated by fermentation, keeping the pile temperature between 55-65°C. This temperature range effectively kills pathogens, insect eggs, and weed seeds in the manure, preparing the compost for subsequent operation in the fertilizer granulator.

This equipment boasts high efficiency and a high degree of automation. By setting the turning frequency and path, continuous operation is achieved, reducing labor input.

A brief discussion on the key role of extrusion in the organic fertilizer industry

fertilizer granulator Oct 28, 2025

In organic fertilizer production lines, there’s a seemingly simple yet crucial process: extrusion granulation. It transforms loose, uneven powdered organic raw materials into uniform, solid granules. This isn’t just a change in form; it’s a crucial step in improving the quality and modernizing the development of organic fertilizer.

Although rich in nutrients, unprocessed powdered organic fertilizer faces numerous challenges in practical application. First, its low density and bulk increase storage and transportation costs. Second, during application, powdered fertilizer is easily dispersed by the wind, resulting in fertilizer loss and environmental pollution. Extrusion technology specifically addresses these issues.

The extrusion process applies tremendous pressure to a fertilizer granulator, forcing the fine fertilizer powder through a specialized die, where it is squeezed into uniform, high-density, and strong granules.

The widespread adoption of extrusion granulation technology marks a significant shift in the organic fertilizer industry from extensive to refined, and from traditional to modern. This enables the standardization and commercialization of organic fertilizer products, shedding their image as “earth-based fertilizer” and making them more readily accepted and trusted by large-scale farms and specialized agricultural practitioners.

In short, these tiny fertilizer pellets embody not only rich organic matter but also the wisdom of modern processing technology. Extrusion molding, as a core component, continues to provide solid technical support for improving quality, increasing efficiency, and promoting green development in the organic fertilizer industry.

Small pellets, big impact: The evolution of organic fertilizer through granulation

fertilizer granulator Oct 28, 2025

In organic fertilizer production, granulation is more than just a cosmetic enhancement. Its primary purpose lies in practicality. Powdered organic fertilizers have a low density and are bulky, taking up a lot of space during storage and transportation. They are also prone to generating dust, leading to nutrient loss and environmental pollution. Granulation compacts the material, significantly reducing its volume, making long-distance transportation and economical storage possible.

More importantly, granulation profoundly impacts the ease and efficiency of fertilization. Uniform granules facilitate mechanized spreading, adapting to the operational needs of modern large-scale farms. Furthermore, their compact structure regulates the release rate of nutrients into the soil, preventing rapid decomposition and providing a more stable and long-lasting nutritional supply for crops.

So, how are various agricultural and forestry wastes transformed into uniform granules? Currently, mainstream granulation processes, such as disc granulators and double roller press granulators, each have their own advantages.

The advancement of granulation technology, from dusty powder fertilizer to uniform, uniform granules, is a significant step toward the modernization and standardization of traditional organic fertilizers. It has transformed organic fertilizer from a traditional “homegrown” method into a standardized commodity that can be integrated into modern agricultural production systems. These tiny granules embody the industry’s unwavering pursuit of efficiency, environmental protection, and practicality.

New type organic fertilizer granulator: Core equipment for efficient organic fertilizer conversion

fertilizer granulator Oct 27, 2025

With the development of organic agriculture, the diversification and high moisture content of organic fertilizer raw materials (such as straw, livestock and poultry manure, and mushroom residue) have driven technological upgrades in new type organic fertilizer granulators. Their optimized design, tailored to the characteristics of these raw materials, has significantly improved production efficiency and the quality of the finished product.

The new type organic fertilizer granulator features a new raw material conditioning system and an anti-sticking device. The conditioning system precisely controls the addition of steam or warm water to adjust the high-moisture organic fertilizer raw materials to a suitable moisture content for granulation (40%-50%), preventing clumping and loose granules. The anti-sticking device sprays a special wear-resistant coating on the inner wall of the granulation chamber, reducing the stickiness of the organic fertilizer raw materials and reducing cleaning frequency.

In terms of workflow, pre-treated organic fertilizer raw materials first enter the conditioning system for humidity and temperature adjustment before being transported to the granulation chamber. The spiral or extrusion mechanism within the granulation chamber mechanically compresses the raw materials into granules. The granules are then trimmed to a uniform size by a cutting device before entering a cooling system for final shaping.

The core value of the new type organic fertilizer granulator lies in its ability to efficiently process highly viscous and high-moisture organic fertilizer raw materials. The resulting granules are high in strength and water-solubility, while also reducing raw material waste. This equipment provides support for large-scale, high-quality production in the organic fertilizer industry.
