Disc Granulator

The Introduction of Disc Granulator

Disc granulator adopts circular structure with above 93 granulation rates, which is applicable for transferring powder, granular or small sized non-viscous materials, such as coal, cement, clinker, fertilizer and other materials. At the same time, it is also a kind of grain making machine, which has the advantages of a uniform particle, high granulation rate, stable operation and long service life, and it is the ideal granulating equipment. The disc granulator also has other names, such as disk grain making machine or disk granulator. The disc granulator machine is also known as a feeding device, which can transport materials uniformly to the next process and can withstand high storage pressure during the process. The disk granulator structure is very simple, easy to use, and the performance is also relatively superior. It is often used in the field of gold concentrator, coal mining plant, chemical plant.

The Features of Disk Granulator

• Reasonable structure, light weight, short length, flexible and convenient layout, and it is suitable for the transformation of old plants.
• Adjustable large obliquity. It adopts point gasket, which is convenient and flexible to adjust.
• It adopts the unique unpowered combination and scraper integration so that the power consumption of auxiliary equipment is reduced.
• The dish consists of disk body and disk section, reducing main motor power. The pitch can be adjusted up and down along the disc body. The end of the plate section is a side flange, which can ensure that the material ball will not be pulled or torn when the material ball is out of the plate.
• The new desilting design, by no power combination scraper cleaning edge, bottom and disc angle with the unique treatment technology. Desilting ball effect is good, and will not appear big mud. 90% material ball diameter is in the 3-5mm range.

The Structures of Disc Granulator

Applications of Disc Granulator

Since the space of disc granulator is not very large, it is suitable to transport various non-viscous materials in the form of powder, particle or small pieces, such as pulverized coal, cement, limestone, coal gangue and other materials. The disc granulator structure is very simple, easy to use, and the performance is also relatively superior. It often appeared in the field of gold concentrator, coal mining plant, chemical plant.

The Applications of Disc Granulator

The Working Principle of Disc Granulator

When the disk granulator works, the raw material powder is atomized with water in the double-shaft mixer, forming the ball core with very uniform particle size, and then sent into the balling disk for ball formation. The water content of the pellet should be controlled at 12 ~ 14%. Most of the water should be added in the double-shaft mixer. 

Only a small amount of water should be added in the ball-forming dish, and the added water should be controlled at about 0 ~ 3%. Dry powder granulation is directly added in the ball into the disk, and spray an appropriate amount of water, raw material into the disk after the impact of centrifugal force, friction and gravity, along the parabola. 

Due to the bond and plasticity of materials, they bond with each other in the process of movement and gradually become larger. When inclination, edge, rotation speed and moisture of the ball disc are fixed, the balls of different sizes will leave the edge and roll downward according to different separation angles due to different gravity. 

Material ball in the continuous rolling process will continue to discharge water of the ball. Due to the adhesive property of the material and the natural volatilization of liquid film on the surface, the material ball has a certain strength, and then it is discharged from the edge of the disk with the rotation of the inclined disk body.
