Structure Composition and Working Principle of Disc Granulator

Disc granulator is a kind of forming equipment that manufactures powdered materials into specific shapes. It is widely used in petrochemical, pharmaceutical, food, building materials, mining and metallurgy, ceramics, rubber, plastics, fertilizers and other industries.

1. Structure Composition of Disc Granulator

The disc granulator is mainly composed of disc, scraper device, pinion gear, reducer, motor, angle adjustment screw, base and inner gear ring. The reducer and the motor are driven by a flexible belt, so the starting is stable. The base of the pelletizing disc is welded by steel plate, which is strong and durable without deformation. The main gear of the granulator generally adopts high frequency quenching, which effectively extends its service life.

2. Working Process and Principle

The disc granulator is to add water to the powder, and a thin water film is formed on the surface of the powder particles. Due to the surface tension of the water, the water and the powder combine to form a small nucleus, which follows the rotation of the disc. , The ball core absorbs materials during rolling and gradually turns into particles. The particles roll to the edge of the disc under the action of centrifugal force. During this process, the particles continuously stick to the powder and become spherical, and the spherical materials are discharged under the action of centrifugal force. Disc body: The materials that have become balls are continuously discharged from the disc body, and new materials are continuously replenished into the tray. The above process is repeated again and again to make the powdery materials become spherical products.

3. Advantages of Disc Granulator

This type of equipment has simple structure, light weight, flexible and convenient process layout; it can control the particle size and output of the ball by adjusting the inclination angle of the ball disc, the motor speed and the amount of water spray.
