Material pretreatment: Firstly, the material needs to undergo pretreatment, including crushing, screening, and appropriate mixing, to ensure the uniformity and suitable particle size of the material, as well as control the humidity and viscosity of the material to make it suitable for the granulation process.
Feeding and conveying: The pre treated material is evenly fed into the rollers of the granulator through the feeding system. Accurate control of the feeding system is crucial for ensuring uniform distribution of materials and continuity of the granulation process.
High pressure squeezing: When the material enters between the rollers, the hydraulic system provides stable pressure, allowing the two sets of rotating rollers to apply high pressure to the material. Under high pressure, the material undergoes plastic deformation, the distance between molecules decreases, the gaps between material particles are compressed, and the material is bonded and formed under high pressure.
Particle formation and discharge: Under the squeezing effect of the roller, the material gradually forms continuous strips. As the roller rotates, the strips are squeezed out and naturally break into particles. These particles typically have high hardness and stability, making them suitable for subsequent processing or direct application.
Cooling and post-treatment (optional): For certain materials, the granulated particles may need to be cooled to stabilize the particle structure and prevent deformation or adhesion due to high temperatures. The cooled particles can also be processed through a crushing and screening system to remove unqualified particles, ensuring the quality of the final product.
