What is a Disc Granulator?

A Disc Granulator, also known as a pan granulator, is a key piece of equipment in solid material processing. It consists of a large, inclined rotating disc. Raw materials (typically a mixture of fine powders and a liquid binder such as water) are continuously fed into the disc. As the disc rotates, the material is lifted by the friction of the disc surface and then rolls down under gravity. This rolling motion, combined with the controlled addition of liquid, causes fine particles to agglomerate into larger, spherical pellets through a process called granulation. The inclination angle and rotational speed of the disc can be precisely adjusted to control pellet size and density.

Core Applications: What Fields is the Disc Granulator Suitable For?

Our Disc Granulator is designed for versatility and is an ideal choice for the following industries:

• Fertilizer Production Lines: It is the preferred equipment for producing uniform granules of organic fertilizer, NPK compound fertilizer, and urea-based fertilizers.

• Cat Litter Manufacturing: Effectively forms uniform, highly absorbent pellets from raw materials like bentonite, sawdust, and silica.

• Mineral and Chemical Processing: Used for granulating powdered ores, chemicals, and other industrial materials to reduce dust and improve flowability.

Whether you are establishing a new organic fertilizer production line or upgrading an existing compound fertilizer plant, our Disc Granulator provides a reliable and efficient granulation solution.

How Does the Lane Disc Granulator Work?

Its operating principle is elegantly simple, which is key to its high reliability and low maintenance requirements.

1. Feeding: Pre-mixed raw materials are fed into the rotating granulating disc via a belt conveyor or feeder.

2. Liquid Addition: A spray of water or binder is introduced through nozzles to moisten the powder, initiating the nucleation process.

3. Pellet Formation: As the disc rotates, the moistened fines begin to aggregate into small nuclei. Through continuous tumbling and layering, these nuclei gradually grow into spherical pellets.

4. Particle Size Classification: Thanks to the inclined design, matured pellets reaching the desired size migrate to the edge of the disc and overflow for discharge, while smaller particles continue to circulate and grow.

5. Discharge: Uniformly sized pellets are discharged from the machine, ready for the next drying or cooling process in your complete fertilizer production system.

Highlighting the Advantages of Our Granulation Equipment.

For fertilizer producers, a core objective of investing in equipment is to manufacture products that meet high market standards and are competitive. Among these standards, physical indicators of fertilizer granules—such as uniformity, strength, and flowability—are key focuses for many purchasers and agricultural guidelines, as emphasized by the Food and Agriculture Organization (FAO) [refer to FAO’s guidance documents on fertilizer specifications]. The Henan Lane Disc Granulator is designed from the ground up to target these quality requirements, empowering our clients to effortlessly produce granules that are not only compliant but also of superior quality.

Why do numerous global customers choose our granulation equipment?

• High Balling Rate and Uniform Granules: Achieves a balling rate exceeding 90%, producing strong, uniformly sized pellets with a smooth surface.

• Low Energy Consumption: The simple mechanical design requires lower operating power compared to other complex granulators, reducing your operational costs.

• Easy Operation and Adjustment: Pellet size can be easily controlled by adjusting the disc’s inclination angle, rotational speed, and material moisture content. This flexibility is crucial for customized fertilizer production.

• Robust and Durable Construction: Manufactured with high-quality steel, with optional acid-resistant or stainless-steel linings for corrosion resistance and long service life.

• Low Maintenance Cost: Few moving parts and a design that facilitates inspection simplify daily maintenance and reduce downtime.
