Granulation Process and Equipment Advantages of the New Type Organic Fertilizer Granulator

fertilizer granulator Aug 22, 2025

The new type organic fertilizer granulator utilizes the mechanical agitation force of high-speed rotation and the resulting air dynamics to continuously mix, granulate, spheroidize, and compact fine powders within the machine, achieving the desired granulation effect.

The resulting granules are spherical with a sphericity ≥0.7, a particle size generally ranging from 0.3 to 3 mm, and a granulation rate ≥80%. Particle size can be adjusted appropriately by adjusting the material mixing ratio and spindle speed. Generally, lower mixing ratios and higher spindle speeds result in smaller particles, and vice versa. This machine is suitable for granulating lightweight, fine powders. The finer the basic particles of the fine powder, the higher the sphericity and the better the particle quality. The particle size before granulation is generally required to be less than 300 mesh.

Typical applications of the new type organic fertilizer granulator include chicken manure, pig manure, cow dung, charcoal, clay, kaolin, and other materials. The new type organic fertilizer granulator boasts uniform granulation and a yield rate exceeding 97%, making it the optimal granulation equipment for organic-inorganic compound fertilizers, organic fertilizers, and bio-organic fertilizers. Due to the coarse fiber properties of the material, rotary granulators have a lower granulation rate, while agitator-type granulators cannot process materials with a nitrogen content exceeding 8% (due to sticking to the wall). This granulator overcomes the shortcomings of both, capable of producing both organic and organic-inorganic compound fertilizers with low energy consumption and high-quality granulation.

The new type organic fertilizer granulator‘s housing is welded from thickened, high-quality carbon steel plates. Ancillary equipment includes pulley assemblies, transmission components, a blower head, and a blower tail. The entire machine is sturdy and durable. The core agitator is precision-cast from a high-chromium alloy and undergoes a special heat treatment, resulting in wear resistance over three times greater than that of ordinary steel. It can withstand the high-frequency friction of fine powders for long periods of time. The main shaft and agitator blades feature a modular design and are fastened with high-strength bolts, enabling easy assembly and simple component replacement, reducing maintenance costs. Adjustable support feet on the bottom of the machine adapt to the flatness of the site, ensuring stable operation and reducing vibration-induced noise and component wear.

The role of uniform feeder in fertilizer production line

fertilizer granulator Aug 20, 2025

In the continuous process of fertilizer production, the uniform feeder is the “nerve center” to ensure the coordinated operation of all links. Whether in compound fertilizer production line or organic fertilizer production line, it can improve the stability of raw material supply by more than 50%, and reduce product quality fluctuations from the source.

The uniform feeder adopts a design combining spiral conveying and frequency conversion speed regulation. The conveying screw is made of wear-resistant alloy material, which can adapt to raw materials with different physical properties such as urea granules, phosphate rock powder, fermented organic fertilizer, etc. The feeding amount can be set with an accuracy of ±2%. It can automatically adjust the conveying speed according to the needs of subsequent crushing, mixing, granulation and other processes to avoid raw material accumulation or feed interruption.

In the compound fertilizer production line, it can accurately convey basic raw materials such as nitrogen, phosphorus, and potassium according to the ratio, so that the nutrient deviation in the mixing link is controlled within 2%, which is much better than 8% of manual feeding. When handling wet organic fertilizer raw materials, its anti-blocking spiral structure combined with the vibration device can effectively avoid material adhesion and blockage, ensuring that the feeding amount per minute is stable at more than 98% of the preset value.

Compared with traditional feeding equipment, the uniform feeder does not require frequent manual adjustment, can reduce 80% of operational intervention, and reduce energy consumption by 30%. The material level sensor equipped with the equipment can monitor the inventory of the silo in real time, automatically start and stop the feeding, and realize unmanned continuous operation.

Whether it is connected to the crushing equipment or the mixer, the uniform feeder can lay a good foundation for the subsequent processes through the stable supply of raw materials. Choosing an appropriate uniform feeder can make the fertilizer production process smoother, the product quality more stable, and demonstrate the core value in large-scale production.

Application of Disc Granulators in NPK Fertilizer Production Lines

fertilizer granulator Aug 20, 2025

In the NPK fertilizer production line, disc granulators are a widely used and highly favored granulation equipment.

The disc granulator‘s structure is relatively simple yet unique. It primarily consists of an inclined disc, a drive mechanism, and a spray system. The disc, the core of the granulation process, is typically constructed of high-strength steel to ensure it can withstand the various forces involved in the granulation process. The drive mechanism provides stable rotational power to the disc, ensuring it rotates at an appropriate speed.

The disc’s operating principle is based on the movement and interaction of the materials within the rotating disc. When the mixed NPK fertilizer raw materials are fed into the rotating disc, the disc’s tilt and rotational motion cause the materials to roll upward along the disc’s inner wall due to a combination of centrifugal force, friction, and gravity. During this rolling process, a spray system applies a binder to the material. The binder acts like “glue,” gradually binding the loose raw material particles together and causing them to aggregate and grow. Over time, these agglomerated particles continuously roll and collide within the disc, further compacting and shaping them, ultimately forming relatively uniformly sized round granules that roll off the disc’s edge, completing the granulation process.

Disc granulators offer numerous advantages. First, they produce fertilizer granules with high roundness, excellent appearance, and strong market competitiveness. Second, they are relatively simple to operate and easy to master, requiring minimal operator skill. Furthermore, disc granulators are highly adaptable and can produce fertilizer granules of varying sizes to meet diverse market demands by adjusting parameters such as disc speed, tilt angle, and binder spraying rate to meet specific production needs.

However, disc granulators also have limitations. For example, compared to some large-scale granulation equipment, their production efficiency may be relatively low, making them less suitable for large-scale industrial production. Furthermore, when processing high-viscosity raw materials, material may stick to the disc, affecting granulation efficiency and equipment operation. Nevertheless, due to their unique advantages, disc granulators still play an important role in the production of NPK compound fertilizers by small and medium-sized enterprises, as well as in production scenarios where the appearance of fertilizer granules is a high priority.
