The disc granulator occupies an important position in the granulation field due to its unique working mode. A deep understanding of its working principle can help to better utilize this equipment for production.

The disc granulator is mainly composed of a power system, disc, feeding device, spraying device, and other parts. The power system provides the operating power for the entire equipment, ensuring that the disc can rotate stably.

At the beginning of the work, the feeding device uniformly transports the pre treated powdered material onto the rotating disc. At this time, the disc is continuously rotating at the set speed under the drive of the power system.

During the rotation of the disc, the material is subjected to a combination of multiple forces. Centrifugal force drives the material to move towards the edge of the disc, while frictional force drives the material to move upward along the inner wall of the disc. Under the combined influence of these two forces, the material forms a specific motion trajectory on the disc, constantly circulating between the bottom and top of the disc.

The spraying device plays a crucial role in this process. It evenly sprays adhesive or an appropriate amount of water in a mist form onto the moving material. The role of adhesive is crucial as it can reduce the surface tension between material particles, making it easier for particles to attract and bond with each other. After the adhesive is sprayed onto the material, small powder particles gradually gather together to form tiny particle nuclei.

As the disk continues to rotate, these particle nuclei continuously roll and collide, coming into contact with the surrounding powdery materials and adsorbing them, thereby increasing their own volume. During this process, the shape of the particles gradually becomes regular.

In order to obtain ideal granular products, operators can adjust some parameters. The rotational speed of the disc is a key parameter, and the speed directly affects the motion and residence time of the material on the disc, thereby affecting the size and uniformity of the particles. In addition, the spraying amount and frequency of the adhesive also need to be precisely controlled according to the characteristics of the material and production requirements. If too much adhesive is sprayed, the particles may become too large and prone to clumping; Insufficient spraying may lead to difficulty in forming particles.

The disc granulator achieves efficient conversion from powdered materials to granular products through the collaborative work of these components and clever use of force, providing a reliable granulation solution for industrial production.
