How Disc Granulators Make Organic Waste into Granules?

Disc granulator plays a crucial role in the process of transforming organic waste into granules. The granulation process involves several steps that leverage the design and functionality of this granulation machine. Here’s a step-by-step guide on how disc granulator makes organic waste into granules.

1. Feedstock Preparation

The process begins with the preparation of organic waste feedstock. This can include a variety of materials such as kitchen waste, crop residues, and green waste. It’s important to ensure that the feedstock is properly sorted and any non-organic contaminants are removed. You may need organic fertilizer crusher, dewatering machine or compost fermentation equipment.

2. Feeding the Materials

The prepared organic waste is then fed into the pan granulator. The feeding mechanism may vary depending on the specific design of the granulator, but typically, a conveyor belt or a feeding system from our company is used to introduce the organic waste onto the rotating disc.

3. Rotating Discs Action

The heart of the disc granulator is the rotating disc or discs. These discs are set at an angle and are connected to a central shaft. As the discs rotate, they create a tumbling motion for the organic waste materials.

4. Spraying Liquid Binder (Optional)

In some cases, a liquid binder may be sprayed onto the organic material during the granulation process. This binder can be a solution containing water or other substances that help in agglomerating the organic powder into granules.

5. Granulation and Agglomeration

The rotating motion of the discs causes the organic waste materials to agglomerate and stick together. This agglomeration process is essential for forming granules. The rotating discs create a dynamic environment where the particles collide and adhere, forming spherical or cylindrical granules.

6. Adjustable Disc Angles

Disc granulators often feature adjustable disc angles. This allows operators to control the size and density of the granules produced. By altering the angle of the discs, the residence time of the material on the discs can be adjusted, impacting the final characteristics of the granules.

7. Particle Size Control

The speed of the rotating discs and the size of the screen or grate beneath the discs contribute to controlling the particle size of the granules. Smaller particles pass through the screen, while larger ones are retained and continue to grow through additional collisions.

8. Collection and Screening

As the organic waste is transformed into granules, they are collected and screened to separate any undersized or oversized particles. This screening step ensures that the final product meets the desired specifications. You may need SX rotary screening machine to help you finish the granulation process.

9. Drying (Optional)

Depending on the moisture content of the organic waste and the desired characteristics of the final granules, a drying step may be employed to reduce moisture levels. This can be crucial for the storage and application of the organic fertilizer. You can select drum dryer to reduce this pellets’ moisture.

10. Packaging and Storage

The final step involves packaging the granulated organic fertilizer for distribution or storage. Proper packaging ensures the longevity and quality of the organic fertilizer product. You are available to choose different kinds of automatic bagging machines according to your production needs.

In summary, disc granulators make organic waste into granules by leveraging the mechanical action of rotating discs, creating a dynamic environment for agglomeration. This controlled process results in the formation of uniform and high-quality organic fertilizer granules ready for use in sustainable agriculture practices.
