The annual production line of 50000 tons of granular organic fertilizer mainly includes fermentation equipment, granulation equipment, and screening equipment.

Fermentation equipment

Fermentation is one of the key links in the production of granular organic fertilizers, and the main equipment includes a fermentation tank and a tipping machine. The fermentation tank is used to store materials for aerobic fermentation. The tipping machine is used to flip materials during the fermentation process, allowing them to come into full contact with air and accelerate the fermentation process.

Granulation equipment

Granulation equipment is the core equipment for the production of granular organic fertilizers, mainly divided into two types: disc granulator and agitator toothed granulator. The disc granulator uses a high-speed rotating disc to knead the fermented material into granules. The stirring teeth granulator uses the stirring teeth to force the material into particles, which has higher production efficiency.

Screening equipment

The screening equipment is used to screen the particles after granulation, and the main equipment includes a vibrating screen and a flat screen. The vibrating screen separates materials with different particle sizes through vibration, while the flat screen separates particles from unqualified products by swinging back and forth.

The main process flow of the granular organic fertilizer production line includes three stages: fermentation, granulation, and screening.

Fermentation process

The quality of the fermentation process directly affects the quality of the granular organic fertilizer. In this process, the raw materials are added to the fermentation tank, and through the irregular flipping of the stacker, the raw materials are fully in contact with oxygen for rapid fermentation. The fermentation time is generally 7-10 days.

Granulation process

The fermented material is fed into the granulation equipment and made into granules through a disc granulator or a toothed granulator. In this process, the size and shape of particles can be controlled by adjusting device parameters. After the granulation process is completed, the embryonic form of granular organic fertilizer has been formed.

Screening process

The screening process is the final and crucial step in the production process. The vibrating screen and flat screen will screen the particles after granulation, separating qualified particles from unqualified particles and impurities. In this process, it is necessary to select the appropriate mesh size according to the product requirements to ensure product quality.
