Mastering dry granulation technology for fertilizer processing

by organic fertilizer production line

In fertilizer processing, dry granulation boasts the core advantages of “no high-temperature drying and low water consumption,” making it a crucial forming technology suitable for various fertilizer types. It requires minimal moisture, relying solely on a small amount of binder and mechanical pressure to shape dry powder raw materials, simplifying the process, reducing energy consumption, and aligning with green production requirements.

The core of the process relies on fertilizer granules compaction technology to achieve physical shaping, resulting in a simple and controllable process. First, uniformly pulverized and mixed dry fertilizer powder (such as NPK compound fertilizer or decomposed organic fertilizer powder) is fed into a fertilizer compaction machine. Pressure is applied through roller extrusion and other methods to bind the raw materials into granules. These granules are then sieved and graded, with substandard granules returned for reprocessing, forming a closed loop.

Compared to wet granulation, it offers significant energy-saving and consumption-reducing advantages, eliminating the energy consumption and equipment investment required for drying. It has low tolerance for raw material moisture, is suitable for low-moisture dry powders, avoids clumping and moisture reabsorption problems, and is more adaptable to heat-sensitive and volatile nutrient fertilizers, maximizing fertilizer efficacy.

Two key aspects need to be controlled in practical operation: First, the raw materials must be crushed to the appropriate particle size and thoroughly mixed to lay the foundation for the implementation of fertilizer granules compaction technology and ensure uniform molding; second, the pressure must be precisely controlled through the fertilizer granules compaction machine. This process is widely applicable to medium and low concentration compound fertilizers and organic-inorganic compound fertilizers, and is especially suitable for scenarios with water scarcity and high environmental protection requirements.

Roller press granulation technology: A reliable choice for improving the strength and uniformity of fertilizer granules

by organic fertilizer production line

The strength and uniformity of fertilizer granules directly affect their transportation and storage stability and application effectiveness, making them a core indicator of high-quality fertilizers. Roller press granulation technology, with its unique principle of “dry extrusion and die-hole molding,” can precisely control particle characteristics from the molding source, effectively improving strength uniformity.

Roller press granulation uses the synchronized pressure rollers of a fertilizer compaction machine to apply constant pressure to dry powder raw materials that have been mixed by a fertilizer mixer and screened by a fertilizer screener machine. The raw materials are then extruded and molded through die holes. The fertilizer compaction machine’s pressure control is precise, and the roller speed and pressure are constant, ensuring that each granule receives the same extrusion pressure, thus preventing strength differences caused by uneven pressure from the source.

This technology has wide raw material adaptability; NPK compound fertilizers and other materials, after pretreatment, can be stably granulated through the fertilizer compaction machine. At the same time, the precise feeding system of the fertilizer compaction machine can stabilize the raw material supply speed, avoiding local pressure changes caused by feeding fluctuations; secondary screening after molding removes irregular particles, further improving the consistency of finished product particle size and strength.

In practical applications, fertilizer granules produced by roller press granulation have a coefficient of variation in strength of ≤5%, far superior to traditional processes, with a transportation pulverization rate of less than 2%. This meets the high requirements for particle stability in large-scale planting, reducing fertilizer waste and ensuring uniform application. In summary, roller press granulation technology, through precise pressure control and process optimization, can significantly improve the strength and uniformity of fertilizer granules, providing strong support for the production of high-quality fertilizers.

Fertilizer compaction machine dry granulation: Technological support for fertilizer processing

by organic fertilizer production line

In the field of fertilizer processing, dry granulation technology using fertilizer compaction machines has become a key link in promoting green industrial upgrading and improving production efficiency, thanks to its unique advantages. Compared to wet granulation, this technology does not require the addition of water and binders, achieving raw material shaping through mechanical extrusion. Its importance is reflected in several core dimensions, including environmental protection, raw material adaptability, and product quality.

Environmental upgrading is one of the core values of dry granulation. Wet granulation requires a subsequent drying process, which consumes a lot of energy and easily generates exhaust gas pollution. Dry granulation, however, eliminates the need for drying, significantly reducing energy and water consumption while minimizing pollutant emissions, perfectly aligning with green production policies.

Expanding the range of adaptable raw materials enhances industrial flexibility. Dry granulation is more compatible with varying raw material moisture content and composition. Whether it’s organic raw materials such as livestock and poultry manure compost or straw powder, or inorganic raw materials such as chemical fertilizer intermediates, efficient shaping can be achieved through fertilizer granules compaction machines.

Ensuring product quality enhances application value. The dry granulation process is gentle, preserving the nutrient components in the raw materials to the greatest extent possible, avoiding nutrient loss caused by high-temperature drying. At the same time, the granules formed by fertilizer extrusion technology have uniform hardness and good solubility, facilitating storage, transportation, and application. This technology is suitable for large-scale planting scenarios such as mechanical fertilization, improving fertilizer application efficiency and nutrient conversion rates, and providing support for improving the quality and efficiency of agricultural production.

Three core equipment pieces build a robust quality defense line for NPK granular fertilizers

by organic fertilizer production line

The market competitiveness of NPK granular fertilizers hinges on granule strength, particle size uniformity, and nutrient stability. The progressive synergy of the fertilizer compaction machine, fertilizer screener machine, and NPK fertilizer granulator, from molding and strengthening to screening, builds a robust quality defense line at every stage.

The NPK fertilizer granulator is the first line of quality control. After precisely proportioned nitrogen, phosphorus, and potassium raw materials are fed into the equipment, they are formed into preliminary granules through wet rolling or dry pre-molding. This ensures that the multiple nutrients are evenly distributed within the granules, preventing stratification, and also initially controls the particle size range, laying the foundation for subsequent quality improvement.

The fertilizer compaction machine undertakes the mission of strengthening the granules. The initially formed granules lack sufficient strength and are prone to pulverization in subsequent stages. After precise extrusion, the internal structure of the granules becomes denser, significantly increasing strength and resulting in a more regular shape. Especially in dry granulation scenarios, the combination of these two machines can increase the granule formation rate to over 95%, meeting the needs of storage and transportation.

The fertilizer screener machine is the final quality control officer. The granules, after molding and strengthening, are graded by the multi-layer screens of the screening machine, removing oversized, undersized, and damaged unqualified products. Qualified products enter the packaging stage, while unqualified products are returned to the granulator for reprocessing, forming a closed loop that ensures uniform particle size and reduces raw material waste.

The synergy of these three pieces of equipment achieves controllable quality throughout the entire cycle of NPK granular fertilizer production, from molding to factory delivery. This not only improves the finished product qualification rate but also ensures stable fertilizer efficacy, precisely meeting the core needs of large-scale agriculture for high-quality fertilizers.

A three-step value enhancement process in organic fertilizer production lines

by organic fertilizer production line

In modern organic fertilizer production, a complete production line not only needs to complete basic processing but also achieves significant value enhancement through refined processing.

After the materials have completed fermentation and mixing, the fertilizer compaction machine initiates the refined processing journey. It shapes loose powdery materials into uniformly sized granules using physical pressure. This process not only improves the physical properties of the product, making it easier to store and transport, but more importantly, it lays the morphological foundation for subsequent processing.

The extruded granules then enter the screening stage. The fertilizer screener machine, through a precise screening mechanism, strictly grades the finished product according to particle size specifications. Particles that meet the standards proceed to the next process, while products with unqualified particle sizes are returned to the previous process for reprocessing.

At the end of the entire organic fertilizer production line, the fertilizer coating machine plays a crucial role. This equipment effectively reduces clumping during storage by coating the granules with a special film material, while also enabling the slow release of nutrients. Products treated with coating not only have a brighter appearance but also significantly enhanced functionality and added value.

The coordinated operation of these specialized organic fertilizer production equipment demonstrates the high level of precision in modern fertilizer production. From the shaping process of the fertilizer compaction machine to the fine selection by the fertilizer screener machine, and then to the value-added processing by the fertilizer coating machine, each step contributes to the quality of the final product.
