As one of the high-quality sources of organic fertilizer, cow manure can be converted into granular fertilizer through specific organic fertilizer granulators, improving its convenience in storage, transportation, and use. Based on the characteristics of cow manure and the requirements for final fertilizer, the following are several commonly used types of organic fertilizer granulators:
A disc granulator is a traditional granulation equipment that aggregates cow manure and other organic materials into spherical particles in a rotating disc through centrifugal force. This machine has a simple structure and is easy to operate, especially suitable for producing small and medium-sized organic fertilizer plants.
The rotary drum granulator utilizes the centrifugal force generated by the rotation of the drum and its own gravity to continuously roll and aggregate cow manure and additives inside the drum, ultimately forming round particles. This type of granulator is usually used for large-scale production, and the appearance of the finished granules is beautiful, suitable for granulating various organic materials.
3. Roll squeezing granulator
The roller extrusion granulator applies high pressure to cow manure and auxiliary materials through two or several parallel arranged rollers, extrudes them into strips, and then cuts them into granules. This method is suitable for processing organic matter with high fiber content, producing particles with high strength and not easily broken.
4. New conical granulator
This granulator combines the advantages of traditional disc and drum granulators. By rotating at different speeds in the central cone and peripheral annular area, shear forces are generated, which promote the collision and agglomeration of cow manure between particles. The new conical granulation machine can process materials with high humidity, and the particle forming speed is fast with high particle strength.
Production process of cow manure pellet fertilizer:
Pre treatment: Cow manure undergoes preliminary dehydration, fermentation, grinding, and mixing.
Granulation: Choose a suitable granulator for granulation.
Drying: Use drying equipment to remove excess moisture and improve the stability of particles.
Screening: Unqualified particles are returned to the granulation process for reprocessing.
Encapsulation: To enhance water retention and extend shelf life, particles can be wrapped with a protective film.
Packaging: The final product is packaged according to the specified weight.
matters needing attention
Before choosing a granulator, it is necessary to evaluate the specific composition, moisture content, and target particle size of cow manure.
It is necessary to consider the overall layout and maintenance of the production line to ensure compatibility between the selected granulator and other equipment.
Regularly maintain and clean the granulator to maintain optimal performance and extend its service life.
Through the rational use of professional organic fertilizer pelletizers, cow manure can not only turn waste into treasure, but also produce high-quality organic pellet fertilizers, supporting the development of sustainable agriculture. When selecting and configuring production equipment, it is recommended to consult industry experts or manufacturers for the most suitable technical solutions.
