The working principle of the disc granulator is based on the principles of centrifugal force and extrusion force. Its main components include a rotating disc, feeding system, screen, and transmission device.
The working process of the disc granulator is as follows:
Feeding system: The raw materials are evenly fed into the center of the rotating disc through the feeding system.
Disc rotation: The disc rotates at a certain speed, and the raw material is thrown towards the edge of the disc under the action of centrifugal force.
Particle formation: During the process of throwing towards the edge, the raw material is compressed and rubbed by the disc, gradually forming wet particles.
Screening: The formed wet particles are screened through a sieve installed at the edge of the disc. Only particles that meet the particle size requirements can pass through the sieve, while unqualified particles or raw materials that have not formed particles will be returned to the center of the disc for further processing.
Collection: Qualified particles passing through the sieve fall into the collection device, completing the entire granulation process.
The disc granulator can control the size and shape of particles, as well as the production yield, by adjusting the rotation speed of the disc, the feeding speed, and the aperture of the sieve. The disc granulator has been widely used in industries such as organic fertilizers and feed due to its simple structure, easy operation, and strong adaptability.
