Feeding: Powdery raw materials enter the rotating disc uniformly through the feed opening.
Agglomeration nucleation: the material rolls along the wall of the disc under the action of centrifugal force, and the core of the particles is formed by spray humidification or natural adhesion.
Snowball effect: the particles continuously adsorb fine powder in rolling, gradually increasing to the target particle size.
Discharge: Finished particles overflow from the edge of the disc and enter the next process (drying, sieving, etc.).
