How to Make Chicken Manure Granules in Rotary Drum Pelletizer?

Chicken manure is a valuable organic fertilizer due to its nutrient-rich composition. One effective way to utilize chicken manure is by converting it into granules using a rotary drum pelletizer. This process helps enhance the convenience of handling and application of the fertilizer while preserving its nutrients. In this guide, we will walk you through the steps involved in making chicken manure granules using a rotary drum pelletizer.

Subtitle: Step 1 – Preparing the Chicken Manure

Before using the rotary drum pelletizer, it is essential to prepare the chicken manure properly. Begin by collecting fresh chicken manure from your poultry farm or a trusted supplier. You can use a manure scraper or shovel to gather the manure into a container. Make sure to remove any large debris or foreign objects from the manure, such as feathers or bedding material.

Subtitle: Step 2 – Drying the Chicken Manure

Chicken manure typically contains a high moisture content, which can affect the pelletizing process. To ensure optimal granulation, it is crucial to dry the manure before feeding it into the pelletizer. Spread the collected manure in a thin layer on a clean, dry surface, such as a concrete slab or a drying bed. Allow it to air dry naturally or use mechanical means like fans or a drying machine to expedite the process. Aim for a moisture content of around 20-30% for efficient pelletizing.

Subtitle: Step 3 – Grinding the Dried Manure (Optional)

In some cases, it may be beneficial to grind the dried chicken manure before pelletizing. Grinding can help break down any large particles and make the manure more uniform in size, resulting in consistent granule formation. You can use a hammer mill or a similar grinding machine to achieve the desired particle size. However, this step is optional and can be skipped if the dried manure is already adequately fine.

Subtitle: Step 4 – Preparing the Binder (Optional)

If the chicken manure lacks sufficient binding properties, it may be necessary to add a binder to facilitate granulation. Binders like bentonite clay or carboxymethyl cellulose (CMC) can help improve the pelletizing process. Prepare the binder according to the manufacturer’s instructions and mix it thoroughly with the dried manure. The binder should be evenly distributed to ensure proper adhesion during pellet formation. Keep in mind that the use of a binder is optional and may not be necessary if the manure has adequate natural binding properties.

Now it’s time to operate the rotary drum pelletizer to convert the prepared chicken manure into granules. Follow these steps:

  1. Set up the pelletizer: Position the rotary drum pelletizer in a well-ventilated area with proper power supply. Ensure all safety precautions are in place before starting the machine.
  2. Adjust the settings: Adjust the speed and inclination of the drum according to the desired granule size and production rate. Refer to the manufacturer’s guidelines for specific instructions.
  3. Load the manure: Feed the prepared chicken manure into the pelletizer’s drum. Make sure to maintain a consistent feed rate to achieve uniform granules.
  4. Pellet formation: As the drum rotates, the manure will undergo a tumbling motion, and the granulation process will take place. The rolling action of the drum helps agglomerate the manure particles into granules.
  5. Monitor the process: Regularly inspect the granules during the process to ensure they are forming correctly. Adjust the drum speed or feed rate if necessary to optimize granule formation.
  6. Collect the granules: Once the granules reach the desired size and consistency, they will discharge from the pelletizer. Collect the granules in a clean container or a conveying system for further processing or storage.

Subtitle: Step 6 – Drying and Cooling the Granules

After pelletizing, the chicken manure granules may still contain excess moisture. It is essential to dry and cool the granules to improve their shelf life and prevent spoilage. Spread the granules in a well-ventilated area or use a drying machine to reduce the moisture content to an appropriate level (around 10-15%).

Subtitle: Step 7 – Screening and Packaging

Once the granules are dry and cool, it is advisable to screen them to remove any oversized or undersized particles. This step helps ensure consistent product quality. Use a vibrating screen or a similar device to separate the granules into desired size fractions.

Finally, package the screened chicken manure granules in suitable containers, such as bags or bulk storage, for storage or distribution. Ensure the packaging is airtight and labeled properly with the necessary information regarding the product.

Subtitle: Conclusion

By following these steps, you can efficiently convert chicken manure into valuable granular fertilizer using a rotary drum pelletizer. This process not only helps in proper utilization of poultry waste but also enhances the convenience of handling and application of the fertilizer. Remember to prioritize safety measures during the operation of the pelletizer and adhere to local regulations regarding waste management. For details you can visit
