Disc Granulator

The Introduction of Disc Granulator

The disc granulator is a circular structure that offers a granulation rate of over 93%. It is suitable for transferring non-viscous materials such as coal, cement, clinker, and fertilizer in powder, granular, or small sizes. It is also commonly referred to as a grain making machine due to its ability to produce uniform particles with a high granulation rate. The disc granulator operates stably, has a long service life, and is considered an ideal granulating equipment. It can also be referred to as a disk grain making machine or disk granulator. It serves as a feeding device, ensuring uniform transportation of materials to the next process and withstanding high storage pressure. The disk granulator has a simple structure, is easy to use, and exhibits superior performance. It finds applications in various fields such as gold concentrators, coal mining plants, and chemical plants.

The Features of Disk Granulator

• Reasonable structure: The disc granulator has a well-designed structure that is lightweight and compact, making it suitable for installation in both new and old plants.
• Adjustable large obliquity: The disc granulator allows for flexible adjustment of the obliquity angle, providing convenience and adaptability in different operating conditions.
• Reduced power consumption: The disc granulator incorporates a unique unpowered combination and scraper integration, resulting in reduced power consumption of auxiliary equipment.
• Efficient use of main motor power: The disc granulator is designed with a disk body and disk section, which reduces the power requirements of the main motor. The pitch of the disc can be adjusted along the disc body, and the side flange at the end of the plate section ensures that material balls are not pulled or torn when discharged from the plate.
• Effective desilting design: The disc granulator features a new desilting design that utilizes a combination scraper to clean the edge, bottom, and disc angle. This design ensures efficient desilting of material, preventing the formation of large lumps. Approximately 90% of the material balls produced have a diameter ranging from 3-5mm.

Applications of Disc Granulator

Gold concentrators: The disc granulator is commonly used in gold concentrators to process gold ore and produce uniform particles for further processing and extraction.

Coal mining plants: The disc granulator is utilized in coal mining plants for granulating coal and coal gangue, transforming them into uniform-sized particles for efficient storage, transportation, and utilization.

Chemical plants: The disc granulator is suitable for granulating various non-viscous materials in chemical plants. It can process materials such as pulverized coal, cement, limestone, and other powdered or small-sized materials.

In summary, the disc granulator’s simple structure, ease of use, and superior performance make it a versatile equipment choice for gold concentrators, coal mining plants, chemical plants, and other industries requiring efficient granulation of non-viscous materials.

The Applications of Disc Granulator

The working principle of the disc granulator can be summarized as follows:

1. Mixing: The raw material powder is mixed with water in a double-shaft mixer to form a ball core with a uniform particle size. The water content in the pellet should be controlled between 12% and 14%, with most of the water added in the mixer.
2. Balling: The ball core is then fed into the balling disk for ball formation. Only a small amount of water (about 0% to 3%) is added in the balling dish. The raw material is added to the disk as dry powder, and a suitable amount of water is sprayed onto it.
3. Granulation: The raw material is subjected to the impact of centrifugal force, friction, and gravity as it moves along a parabolic path in the balling disk. The materials gradually bond and become larger in size due to their adhesive properties and plasticity.
4. Separation: When the inclination, edge, rotation speed, and moisture of the balling disk are fixed, balls of different sizes will separate from the edge and roll downward at different angles due to gravity.
5. Drying and Discharge: The material balls continue to lose water during the rolling process. Due to the adhesion of the material and the natural evaporation of the liquid film on the surface, the material balls gain sufficient strength. They are then discharged from the edge of the disk as it rotates inclinedly.

In summary, the disc granulator uses a combination of mixing, balling, granulation, separation, and drying to form and discharge uniformly sized material balls. The rotation of the inclined disk and the controlled addition of water play important roles in the granulation process.
