Flat die pelleting machines: A flexible solution for processing fiber materials in organic fertilizer

by organic fertilizer production line

In organic fertilizer granulation equipment, flat die pelleting machines are often praised for their adaptability and convenience, but their “flexible advantage” in processing fibrous materials is rarely mentioned. Thanks to its unique structural design, the flat die pelleting machine processes fibrous organic raw materials in a “gentle and adaptable” manner, ensuring molding efficiency while preserving the original characteristics of the material to the greatest extent.

Its “gentleness” stems from the design logic of its core structure. The large-area contact between the flat die and the pressure rollers allows for more even force distribution on the material, avoiding fiber breakage or nutrient damage caused by excessive local compression. For fibrous raw materials such as oil palm empty fruit bunch and decomposed straw, this force distribution allows the fibers to form a “net-like support structure” inside the granules, enhancing particle adhesion without damaging the physical properties of the fibers.

This “flexible processing” is also reflected in the material itself. The die orifice distribution and pressure roller speed design of the flat die pelleting machine allow the fibrous material to naturally unfold and pass through the die orifices in the correct direction during extrusion, reducing the probability of entanglement and blockage. No additional binders are needed; the material can be shaped solely by the inherent toughness of the fibers and the adhesiveness of the material.

With the increasing diversification of organic fertilizer raw materials, the “gentle and adaptable” characteristics of the flat die pelleting machine perfectly meet the needs of resource utilization of fibrous waste. It solves the shaping problem of such raw materials and endows organic fertilizer with superior physical properties and fertilizer efficacy.

Fermentation and application of organic fertilizer

by organic fertilizer production line

In today’s growing emphasis on organic agriculture, mastering scientific organic fertilizer fermentation techniques and application methods is crucial for improving crop yield and quality. Every step, from fermentation turning to field application, requires precise control.

Fermentation Turning: Core Technology of Aerobic Fermentation

Turning operations are a critical link in the aerobic fermentation process of organic fertilizer, directly affecting fermentation efficiency and final product quality. Modern organic fertilizer production mainly uses professional equipment such as trough turners, wheeled turners, and chain plate turners, which can efficiently complete material mixing and aeration. The timing of turning is particularly important – the first turning occurs on the third day after the pile temperature reaches 55°C during the heating phase, every 2-3 days during the high-temperature phase, and extended to 5-7 days during the cooling maturation phase. Proper turning operation requires turning bottom materials to the top and edge materials to the center, ensuring all materials evenly contact oxygen.

Turning is not just simple material mixing, but precise regulation of the fermentation process. Through timely turning, the optimal temperature range of 55-65°C can be effectively maintained, avoiding local anaerobic environments that produce odors, while promoting complete decomposition of organic matter.

Scientific Application: Site-Specific Fertilization Strategies

Organic fertilizer application requires developing personalized plans based on crop type, soil conditions, and growth stages. Base fertilizer application should be done before sowing or transplanting, with organic fertilizer evenly spread and deep plowed 20-30 centimeters to fully mix with soil. Top dressing should be applied during key crop growth periods, supplementing nutrients through trenching or hole application. For facility agriculture, fertigation or drip irrigation methods can be used, applying dissolved organic fertilizer through irrigation systems. Foliar spraying is suitable for crop seedling and flowering/fruiting stages, enabling rapid nutrient supplementation.

Storage Management: Key to Maintaining Fertilizer Efficiency

Proper storage methods are crucial for maintaining organic fertilizer efficiency. Factory storage requires ensuring dry and ventilated warehouses, with moisture-proof pads laid on the ground, stacking height not exceeding 10 layers, and sufficient ventilation spacing reserved. For small-scale farmer storage, well-sealed packaging should be selected and placed in dry, ventilated areas, avoiding rain and direct sunlight. Both factories and farmers should follow the first-in-first-out principle and use within the shelf life to ensure fertilizer effectiveness.

The scientific use of organic fertilizer is a systematic project, from fermentation production to field application, and then to storage management, each link requires professional knowledge and careful operation. Only by comprehensively mastering these technical points can organic fertilizer fully play its role in improving soil and enhancing crop quality, achieving sustainable agricultural development.

Integrated Systems for Modern Organic Fertilizer Production

The scientific application of organic fertilizers begins with efficient production systems. Modern organic fertilizer production line operations integrate advanced organic fertilizer fermentation equipment including the chain compost turner and large wheel compost turner to optimize the aerobic decomposition process. These specialized turning machines ensure proper aeration and temperature control during fermentation, which is fundamental for producing high-quality organic amendments. For enhanced biological activity, the bio organic fertilizer production line incorporates additional microbial inoculation stages following the fermentation process.

Following complete maturation, the fermented material proceeds to the organic fertilizer granulator for transformation into uniform, easy-to-handle pellets. This integrated approach—combining precise fermentation management with controlled granulation—ensures consistent product quality from production through field application. The synergy between optimized fermentation techniques and modern processing equipment enables the creation of organic fertilizers that not only improve soil structure and fertility but also support sustainable agricultural practices by efficiently recycling organic waste into valuable soil amendments.

Working Principle of Double Roller Granulator

by organic fertilizer production line

The double roller granulator is an advanced equipment based on dry extrusion granulation technology, widely used in multiple industrial fields including fertilizers, chemicals, pharmaceuticals, and feed production. The core advantage of this equipment lies in its ability to efficiently convert powdered raw materials without adding large quantities of binders, providing an environmentally friendly and economical solution for modern industrial production.

Core Working Principle: Five-Step Formation Method

The working process of the double roller granulator can be divided into five closely connected stages. First is the raw material feeding and preprocessing stage, where powdered materials are uniformly transported into the equipment through a precise feeding system. Raw materials require strict preprocessing, including controlling appropriate particle size ranges and moisture content to ensure subsequent forming effectiveness.

Next is the crucial roller extrusion forming stage. The core of the equipment consists of a pair of horizontally installed, counter-rotating press rollers made from high-strength wear-resistant materials. When raw materials enter the nip zone between the rollers, tremendous mechanical pressure compresses the powdered material into a dense sheet structure. During this process, air between raw material particles is expelled, molecular distances are reduced, and stable molded bodies are formed through physical forces.

The sheet material formed by extrusion then enters the crushing stage, where it is broken into particles of varying sizes. These particles undergo screening and classification systems, separated according to predetermined sizes. Particles meeting requirements are output as finished products, while oversized or undersized particles return to corresponding processes for reprocessing, ensuring raw material recycling.

Design Features and Technological Innovation

The successful operation of double roller granulators relies on multiple carefully designed technical features. Roller surface design can be adjusted according to raw material characteristics – grooved design increases contact area, while smooth design suits more viscous materials. The fine adjustment function of roller clearance allows the equipment to adapt to different raw material forming requirements.

The equipment’s synchronized rotation system ensures coordinated operation of both press rollers, preventing material deviation. This precise mechanical design not only improves forming efficiency but also guarantees product consistency. The advantages of dry granulation are fully demonstrated in this process – requiring no large amounts of water or binders saves costs while maintaining raw material purity.

Application Fields and Environmental Value

The application scope of double roller granulators is extensive. In fertilizer production, they can uniformly granulate various nutrient elements, improving fertilizer efficiency and application convenience. The chemical industry utilizes this equipment to process dust and powdered raw materials, achieving effective resource utilization. The pharmaceutical industry relies on it to produce uniform drug granules, ensuring product quality.

Compared to traditional wet granulation, double roller granulators offer significant environmental advantages. By eliminating the need for large quantities of water resources and binders, they reduce wastewater discharge and energy consumption. Meanwhile, high raw material recycling rates of 85-95% maximize raw material utilization while minimizing waste.

Future Development Trends

With continuous advancement in industrial technology, double roller granulators are developing toward greater intelligence and efficiency. New material applications improve equipment wear resistance and service life, while the introduction of automated control systems makes operation simpler and more precise.

In the future, this equipment is expected to play roles in more fields, particularly in resource recycling and environmental protection. By converting various industrial by-products into valuable granular products, double roller granulators will make important contributions to the development of circular economy, promoting industrial production toward more sustainable directions.

Synergistic application of NPK fertilizer production lines and BB fertilizer mixers

by organic fertilizer production line

NPK fertilizer production lines are crucial for compound fertilizer production. As a key piece of equipment, BB fertilizer mixers, when integrated with the production line, significantly improve overall production efficiency and product quality. NPK fertilizer production involves processes such as raw material crushing, mixing, granulation, and drying. The mixing stage directly impacts the nutrient balance of the final product, and BB fertilizer mixers are a perfect fit for this requirement.

In the production line, raw materials processed by the fertilizer crusher are delivered to the BB fertilizer mixer via a fertilizer conveyor. Upon startup, the drive system drives the mixing shaft and blades, evenly mixing nitrogen, phosphorus, and potassium, laying a solid foundation for the subsequent granulation process. Inhomogeneous mixing can result in significantly different nutrient distributions in the granulated fertilizer, impacting product quality.

The BB fertilizer mixer’s control system can be linked with the overall production line control system to synchronize parameters such as mixing speed and time, ensuring a smooth production process.

Core requirements for materials processed by the new type two in one organic fertilizer granulator

by organic fertilizer production line

While the new type two in one organic fertilizer granulator simplifies the organic fertilizer production process with its integrated design, it has more specific requirements regarding the adaptability of the processed materials.

Precise control of material particle size is crucial. Raw materials entering the new type two in one organic fertilizer granulator must undergo crushing and screening to ensure uniform particle size controlled within the 1-3 mm range. Large impurities or incompletely crushed lumps in the material will not only clog the equipment’s feed channel and die holes but may also accelerate the wear of internal components, affecting granulation continuity. Excessively fine powdery materials are prone to generating dust and will result in insufficient granule strength after molding.

Material moisture control is critical. The suitable material moisture content is 20%-30%, which needs to be fine-tuned based on the raw material composition. Excessive moisture content causes the material to easily clump together inside the machine, leading to a decrease in granulation rate and potentially causing die blockage. Insufficient moisture content results in a lack of viscosity, making it difficult to form through extrusion or granulation processes, and even if formed, it is prone to breakage.

The material composition ratio must be scientific. The carbon-to-nitrogen ratio of the raw materials should be maintained at 25-30:1. Avoid imbalances in the proportion of single high-nitrogen raw materials (such as poultry and livestock manure) or high-carbon raw materials (such as straw), otherwise the stability of the fertilizer effect after pelleting will be affected. At the same time, the proportion of fiber components in the material should not be too high. Excessive fiber can easily entangle equipment parts, requiring pretreatment to decompose some coarse fibers. If the raw material lacks viscosity, a suitable amount of natural binder can be added to improve the pelleting effect.

Furthermore, the material must be fully decomposed. Undecomposed raw materials may undergo secondary fermentation after granulation in the new type two in one organic fertilizer granulator, causing the pellets to expand and break, and potentially leading to seedling burn during fertilization.

Five key systems in fertilizer production

by organic fertilizer production line

Modern fertilizer production is a highly systematic process involving a complete industrial chain from raw material processing to finished product packaging. Fertilizer production equipment can be divided into five key systems according to the technological process, each playing an indispensable role.

Raw Material Pretreatment System

Raw material pretreatment is the first process in fertilizer production. Crushers are responsible for breaking down bulk raw materials such as potash ore and straw to suitable particle sizes below 8 millimeters. Mixers uniformly blend raw materials including nitrogen, phosphorus, and potassium according to precise formulas, ensuring balanced nutrient distribution. Screening machines remove impurities through vibration screening and precision filtration, providing clean raw materials for subsequent processes.

Core Reaction and Fermentation System

Depending on the fertilizer type, core reaction equipment has distinct characteristics. Organic fertilizer production mainly relies on fermentation turners and maturation tanks, converting organic materials into stable humus through aerobic fermentation processes. Chemical fertilizer production uses equipment such as dissolution tanks, flotation machines, and crystallizers to achieve raw material purification and transformation. Chelation tanks effectively prevent precipitation of medium and trace elements, ensuring fertilizer quality.

Granulation and Forming System

Granulation is a core step in fertilizer production. Extrusion granulators form granules through high-pressure extrusion and are suitable for materials such as organic fertilizers and potassium chloride. Disc granulators utilize centrifugal force to precisely control particle size within the 2-4 mm range. Spray granulators produce water-soluble fertilizers through atomization and drying processes, while coating granulators can precisely control the coating of slow-release fertilizers. Drum granulators, with their large-scale production capacity, are the preferred equipment for NPK compound fertilizer production.

Post-treatment and Packaging System

After granulation, the fertilizer requires meticulous post-processing. A secondary screening machine ensures uniform particle size, while anti-caking equipment uses a special coating agent to prevent clumping during storage. Environmental protection equipment, including dust removal and wastewater treatment systems, ensures the production process meets environmental requirements. The final packaging process utilizes automated equipment for accurate metering and efficient packaging.

Modern fertilizer production lines achieve efficient and environmentally friendly large-scale production through the coordinated operation of various systems. Taking a typical NPK compound fertilizer production line as an example, the entire process from raw material pretreatment to finished product packaging can reach a daily output of 500 tons. The products fully comply with national quality standards, providing a reliable fertilizer guarantee for global agricultural production.

Integrated Fertilizer Manufacturing: Advanced Technologies and Equipment

The comprehensive npk fertilizer production line exemplifies modern fertilizer granulation technology, integrating specialized equipment for optimal efficiency. The process begins with precise formulation using npk blending machine technology, followed by advanced fertilizer granulation processes that include both wet and dry granulation processes. Equipment selection varies by product type, with the disc granulator machine serving as the core of disc granulation production line systems, while the double roller press granulator forms the basis of roller press granulator production line operations for specific material requirements.

Parallel to chemical fertilizer production, the organic fertilizer production line and bio organic fertilizer production line utilize specialized equipment like the windrow composting machine for efficient organic matter decomposition. These diverse fertilizer granulator technologies, from disc granulator systems to specialized pressing equipment, represent the pinnacle of professional fertilizer manufacturing equipment. The continuous innovation in fertilizer granulation technology ensures that modern production lines can meet the growing global demand for both conventional and specialized fertilizers while maintaining high quality standards and environmental compliance across all fertilizer granulation processes.
