Converting fertilizer compost into granules is a process commonly used in the agricultural industry to make it easier to handle, transport, and apply. Granulating composted fertilizer can also help improve its nutrient distribution and release, making it more effective as a soil amendment. Here’s a general overview of the steps involved in turning fertilizer compost into granules:
Select the Right Compost
Ensure that your composted fertilizer is fully matured, free from any contaminants, and has the desired nutrient composition for your specific crops or soil needs. Here, windrow composting turning machine can help you finish the aerobic fermentation of organic waste quickly.
The compost should be properly prepared before granulation. This may include drying it to the right moisture content. Excess moisture can cause issues during the compost granulation process.
a. Mixing: Blend the composted fertilizer with other necessary ingredients, such as binding agents or additional nutrients if required. This mixture should have a homogeneous composition.
b. Granulation: There are several methods for granulating fertilizer compost , including:
- Extrusion: This process involves forcing the compost mixture through a die or screen with the help of an extruder. The compost mixture is shaped into granules as it passes through the die.
- Rotary Drum Granulation: In this method, the compost mixture is introduced into a rotating drum. As the drum rotates, the compost adheres together and forms granules.
- Pan Granulation: A pan granulator uses a rotating pan with high edges. The compost mixture is continuously sprayed with a liquid binder as it moves around the pan, forming granules.

Steps after compost granulation
Drying: After granulation, the newly formed granules may contain excess moisture. They need to be dried to reduce their moisture content to a suitable level for storage and transportation. A rotary dryer is often used for this purpose.
Cooling: The dried granules should be cooled to ambient temperature before packaging to prevent them from clumping due to residual heat.
Screening and Sizing: The granules are usually passed through screens to separate out any oversized or undersized particles, ensuring uniformity in size.
Packaging: Then you can prepare quality compost pellets. The final granulated compost can be packaged in bags, sacks, or bulk containers for distribution and sale.
Quality Control: Perform quality checks on the granules to ensure they meet the desired specifications in terms of size, nutrient content, and other relevant factors.
Storage: Store the granulated compost in a cool, dry place to prevent moisture absorption and maintain product quality.
Application: Farmers and gardeners can then easily apply the granulated compost to their fields or gardens using traditional fertilizer spreaders or seeders.
The specific equipment and methods used for granulating composted fertilizer can vary depending on the scale of production and the resources available. It’s important to consult with experts or manufacturers of granulation equipment for guidance tailored to your specific needs. Additionally, consider local regulations and environmental guidelines when producing and applying granulated fertilizers to ensure sustainable and responsible agricultural practices.
