Disc granulator

1. Description of Disc Granulator

Disc granulator is an important equipment widely used in metallurgy, chemical industry, building material industry and other industries. It is mainly used to convert small particles or fine powder materials into spherical particles with certain strength and uniformity. This equipment uses a rotating disc and a corresponding water spray system, making the material roll on the surface of the disc and gradually form granules.

2. Working Principle

The main component of the disc granulator is an inclined circular disc surface. The material is continuously fed onto the rotating disc and moves down the surface of the disc under the action of gravity. At the same time, an appropriate amount of water (or binder) is uniformly sprayed onto the material through the nozzle, making the particles adhere to each other. As the disc rotates, the material repeatedly rolls on its surface, gradually gathers into a sphere, and rolls to the edge of the disc under the action of its own weight, and is discharged through the outlet.

3. Main Components

1. Disc: It is the main working area of the ball making process, its angle and speed can be adjusted according to production needs.

2. Driving device: Including motor, reducer, etc., providing the required rotating power for the disc.

3. Water spray system: Ensures proper wetting of the material and promotes particle adhesion.

4. Scraper device: Used to clean the materials adhered to the inner wall of the disc, keep the disc clean and improve the ball production efficiency.

4. Applications

1. Metallurgical industry: Used for granulating raw materials such as iron ore powder and limestone powder to improve the permeability of the furnace charge and improve the smelting efficiency.

2. Chemical industry: Applied to the production of fertilizer, catalyst and other products, helping to improve the quality and productivity of products.

3. Building material industry: For example, cement plants use the remaining industrial waste to produce building materials, which is both environmentally friendly and economical.

5. Conclusion

Disc granulator plays an important role in many industries due to its simple structure, easy operation and low maintenance cost. With the development of technology, modern disc granulators are developing toward automation and intelligence, which not only improves production efficiency but also better meets the needs of different users.
