Disc/Pan Granulator

The disc granulator operates based on the principle of wet granulation. It transforms fine powder materials into uniform, round granules through continuous rolling, spraying, and agglomeration inside the rotating disc.

1.Material Feeding

The raw materials (such as organic fertilizer, compound fertilizer, or other powdered materials) are fed into the rotating disc through a conveyor or feeder.
Disc Rotation & Rolling:

The granulation disc rotates at a controlled speed, causing the materials inside to roll and collide, forming small granules.
The angle of the disc (typically 40°-55°) can be adjusted to control granule size.

2.Water Spraying & Agglomeration

A spraying system continuously sprays a controlled amount of water or binder onto the rolling particles, helping them stick together and grow.
The particles gradually increase in size as more fine powder attaches to them.

3.Granule Growth & Shaping

Due to the centrifugal force, gravity, and friction, the granules roll and polish themselves, becoming round and uniform in size.
Fine powder that does not form granules falls back and gets recycled.

4.Granule Discharge

Once the granules reach the desired size, they roll down to the discharge outlet and are transported to the drying process for further solidification.

Key Factors Affecting Granulation Efficiency

1.Disc Angle Adjustment: Controls the retention time of materials and granule size.
2.Moisture Content: Proper water addition ensures smooth granulation.
3.Rotation Speed: Affects the rolling motion and granule formation.
4.Raw Material Properties: The fineness and stickiness of the powder influence granule quality.

The disc granulator is widely used in fertilizer production, chemical industries, and mineral processing, offering a cost-effective, efficient, and eco-friendly granulation method.

1.High Granulation Rate: The granulation rate can reach over 90%, ensuring minimal material waste.
2.Adjustable Disc Angle: The tilt of the disc can be adjusted to optimize granulation efficiency.
3.Durable and Corrosion-Resistant: Made of strong, anti-corrosion materials, ensuring long service life.
4.Easy Operation and Maintenance: Simple structure with user-friendly operation and low maintenance costs.
5.Wide Application: Suitable for organic fertilizer, compound fertilizer, and bio-fertilizer production.
