The disc granulator is a rotating disc mounted on a fixed base. It is one of the most commonly used types of granulation equipment,because it can produce refined granules and provides a highly flexible granulation method. Many variables such as disc angle, speed, feed rate, etc. can be adjusted to control particle size and other characteristics.Disc granulator is a granulation equipment widely used in organic fertilizer and compound fertilizer shaping, petrochemical, pharmaceutical, food, building materials, mining and metallurgy, ceramics, and other industries.

WORKING PRINCIPLE

The disc is installed at a certain tilt angle. The material rolls rapidly in the rotating disc as the disc rotates. When it rises to the highest point, it falls vertically under the obstruction of the scraper. During the rotation of the disk, the particles squeeze and roll with the disk wall under the action of centrifugal force. Due to these comprehensive mechanical extrusions, rolling, and collisions, the powdery materials gather together to form a "cue ball" with the help of the surface tension of the liquid phase. As the "cue ball" increases, it slowly spherifies into complete particles, ranging from small to large. Large, the strength gradually increases and the granulation process is completed until the finished product granularity overflows from the edge of the disc.

DISC GRANULATOR ADVANTAGES: 

*This type of equipment has simple structure, light weight, flexible and convenient process layout;

* the particle size and output of the ball can be controlled by adjusting the inclination angle of the ball disc, the motor speed and the amount of water spray.
