There are many significant benefits to using a rotary drum granulator for granulation of NPK fertilizers. These advantages not only improve the production efficiency and product quality of fertilizers, but also optimize the storage, transportation, and application effects of fertilizers. The following are the main benefits of using a rotary drum granulator to granulate NPK fertilizer:

Improving the physical properties of fertilizers:

Uniform particle size: The rotary drum granulator can produce particles of uniform size, which helps to evenly distribute fertilizers in the soil, avoid local fertilizer concentrations that are too high or too low, and promote balanced crop growth.

Enhanced particle strength: Through the granulation process, the physical strength of the particles is enhanced, reducing crushing and dust generation during storage and transportation, and improving the storage stability and logistics efficiency of fertilizers.

Improve fertilizer utilization efficiency:

Reduce loss: Granular NPK fertilizers are less likely to be blown away by wind or washed away by rainwater than powdered fertilizers, reducing fertilizer loss and improving the retention rate of fertilizers in the soil, thereby increasing fertilizer utilization efficiency.

Controlled release effect: The release rate of granular fertilizers is relatively more controllable, which helps to gradually release fertilizer nutrients, meet the nutritional needs of crops at different growth stages, and avoid excessive or insufficient nutrition.

Convenient storage and transportation:

Small size and heavy weight: Granular fertilizers have a small volume and heavy weight, making them easy to package, store, and transport, reducing the need for storage and transportation space, and lowering logistics costs.

Optimize application effect:

Uniform application: Granular fertilizers are distributed more evenly during application, avoiding the problem of high or low local concentration of fertilizers, helping crops absorb nutrients in a balanced manner, and promoting healthy growth.

Reducing environmental pollution: The application of granular fertilizers reduces the volatilization and loss of fertilizers, reduces environmental pollution, and contributes to the sustainable development of agriculture.

Extended storage time:

Reduce moisture content: Through granulation and drying processes, the moisture content of granular fertilizers is reduced, reducing their moisture absorption and the possibility of mold and deterioration, and extending their storage time.

By using a rotary drum granulator to granulate NPK fertilizer, not only does it improve the physical and chemical stability of the fertilizer, but it also optimizes the application effect and reduces the impact on the environment. It is an indispensable technical means in modern agricultural fertilizer production.

What is the working principle of the cow manure organic fertilizer granulator

fertilizer granulator Aug 27, 2024

The cow manure organic fertilizer granulator is a key equipment used in organic fertilizer production lines to process organic materials such as cow manure into granular fertilizers. The working principle varies depending on the type of granulator, and can be mainly divided into the following categories:

Disc granulator:

Working principle: The raw materials are fed into the rotating disc of the disc granulator, which tilts at a certain angle and rotates at a certain speed. The raw material forms a thin film at the edge of the disc under the action of centrifugal force and gravity. During the rotation process, the raw material particles gradually increase through mutual collision and adhesion, forming spherical particles. Meanwhile, the disc granulator is usually equipped with a water spray device, which can control the humidity during the granulation process to facilitate the formation of particles.

Roll squeezing granulator:

Working principle: After pre-treatment, the raw materials are fed between two relatively rotating rollers. The pressure between the rollers compresses and extrudes the raw material, forming a continuous strip of material. Strip shaped materials are cut into particles of the desired size using a cutting knife. The roller extrusion granulator is suitable for raw materials with low humidity. By adjusting the pressure and spacing of the rollers, the size and shape of the particles can be controlled.

Ring mold granulator (also known as extrusion granulator):

Working principle: After pre-treatment, the raw materials are sent between the ring mold and the pressure roller of the ring mold granulator. There are multiple holes on the ring mold, and the pressure roller applies high pressure to the raw material, forcing it to pass through the holes on the ring mold to form a continuous strip of material, which is then cut into particles by a cutting knife. The ring mold granulator is suitable for various humidity and viscosity raw materials. By adjusting the ring mold aperture and roller pressure, the particle size and density can be controlled.

Drum granulator:

Working principle: The raw materials are subjected to mechanical force and moisture in the drum. Through the rotation of the drum and the design of its internal structure, the raw materials continuously roll, collide, and bond in the drum, gradually forming the required particles. The drum granulator is suitable for processing raw materials with high humidity. By adjusting the speed and internal structure of the drum, the size and shape of the particles can be controlled.

The cow manure organic fertilizer granulator processes raw materials into granules through different working principles, which not only improves the storage and transportation efficiency of fertilizers, but also enhances the application effect of fertilizers. It is an indispensable equipment in organic fertilizer production. When choosing a granulator, the most suitable type should be selected based on the characteristics of the raw materials, the expected particle size and shape, and production requirements.
