Disc granulator: How does it work?

We designed disc granulator can make the raw materials into round pellets.How does it work? The disc granulator mainly relies on centrifugal force. After starting the disc granulator, its motor  will guide the movement of the belt. When the rotating disk reaches a certain speed, the spray device sprays water vapor into the container.Therefore, the raw materials in the rotating disk will compress each other, forming round particles in the process. When reaching the top of the disc container, they will eventually exit the disc through the discharge port.In addition,you can set the suitable granular size according your production needs.

Why disc granulator can help you make perfect pellets?

We have designed disc granulator with different specifications. It can meet any production needs of your particle diameter of 0.5 ~ 3.5m. The screening function of the disc granulator itself is an important feature of it.It can save you production costs in fertilizer production. Generally speaking, you can directly get the particle size you want through this function. This method eliminates the need for additional screening processes. However, if you are very strict about the diameter of the fertilizer, we recommend that you install a screening machine after the disc granulator. It can help you screen out more uniform and better-looking fertilizer particles.

How do you use a disc granulator efficiently in production process?

You can adjust an incline about 40-55 degrees from the ground. The particle sizes formed by different inclination angles are also different. In general, the larger the angle of inclination, the larger the particle diameter.

After the disc rotates, the raw materials are added into the disc container from the inlet at the top, and the spray device is activated to add water vapor to help the raw materials agglomerate into particles faster.

Some raw materials are agglomerated into granules and sent out through the discharge port. As the material is reduced,you should putmore material is into the disc granulation vessel, which runs continuously.

5 Pan Granulator Design Highlights To Increase Your Fertilizer Making Efficiency

The disc granulator is composed of multiple parts, and the overall design is exquisite and durable. Every part of our granulator adopts a unique design. In order to understand its advantages, we will briefly cover these individual parts:

The chassis of the disc granulator is designed as an integral arc with a rim to accommodate the tumbling pellets. The lining inside the disc is a highly efficient glass-reinforced plastic. They are more durable and more resistant to corrosion. The bottom of the disc is strong, durable, and not easily deformed because we use multiple radiating steel plates.

The disc granulator relies on gears to drive the disc movement. Our companydisc granulator adopts high-frequency quenching production technology. The large gear of the granulator is twice as long as the ordinary gear, which can quickly start production work and reduce production time.

You can check the model and capacity of these parts in the table below. They are also of high quality and durability.

We continue to integrate domestic and foreign advanced accessories, such as Siemens, Schneider, ABB, Delivery, Baosteel and other excellent accessories. We always provide customers with convenient and stable equipment. And adopt German Siemens PLC centralized control system, which can help you realize fully automatic production in the whole production process.

The bottom of the disc granulator for fertilizer production is heavier than normal and the steel plate thickens. Machine installation does not require fixing bolts. Even when the machine is running intensely, it runs smoothly and steadily.
