How does a granulator work

News Disc Pelletizer750

Organic fertilizer granulator is a specialized machine equipment used for producing organic fertilizers. Its working principle mainly involves multiple steps such as raw material processing, mixing, granulation, drying, and cooling. The following is a detailed workflow:

Using materials

Using materials

material processing

  • Raw material selection: The main raw materials required for organic fertilizer granulators are various organic waste, crop straw, livestock manure, etc.
  • Preliminary processing: Clean, screen, and crush the raw materials to ensure their quality and particle size meet the requirements, and to ensure the smooth progress of subsequent process steps.

Mixing and regulating moisture

  • Mixing: Mixing different types of raw materials in a certain proportion to meet the standards for making organic fertilizers.
  • Adjust moisture: Adjust the humidity of the raw materials to ensure their suitability for subsequent granulation processes. This step is crucial for the granulation effect.

Granulation

  • Granulation process: The mixed raw materials are pressed into granules through the mold of the granulator. The shape and size of the mold can be adjusted as needed. During the pressing process, cellulose and hemicellulose in the raw materials will be destroyed to facilitate subsequent microbial decomposition.
  • Granulation type: Depending on the different types of granulators (such as disc type, drum type, vertical type, etc.), the shape and particle size of the produced particles will also vary. But overall, the granulation process compresses the raw materials into granules through the action of mechanical force.

Drying and Cooling

  • Drying: Place the processed organic fertilizer particles in a well ventilated area or dry them using specialized drying equipment to reduce moisture content, improve fertilizer stability and shelf life.
  • Cooling: The dried organic fertilizer particles are cooled by a cooling device for subsequent packaging and storage.

Screening and packaging

The organic fertilizer particles that have been dried and cooled need to be screened to remove particles that do not meet the standards, and then packaged and sold.

maintenance

In order to ensure the normal operation and prolong the service life of the organic fertilizer granulator, regular maintenance and upkeep are necessary. This includes checking whether the various components of the machine are working properly, replacing worn parts in a timely manner, and maintaining good lubrication.

In summary, the organic fertilizer granulator converts organic waste into high-quality granular organic fertilizer through a series of complex process steps. The application of this machine not only improves the utilization rate and quality of organic fertilizers, but also promotes the sustainable development of agriculture.
