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

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.
