Do you know why so many people start to invest organic fertilizer granules manufacturing plant? At present, more and more people are investing in organic fertilizer granules production. Because the demand for organic fertilizer on the market is increasing, and the profit of organic fertilizer is large. For example, on 3rd August 2023, a customer from Singapore wanted to make pellet organic fertilizer. For this, if you have organic waste which need to be disposed, it will be a right time to set up an organic fertilizer granules producing plant.

How to Reduce the Moisture of Organic Fertilizer Material?

When you want to produce organic fertilizer granules successfully, adjusting the moisture of organic fertilizer material is the most important step. Hence, Singaporean client wanted to know how to reduce the moisture of material before composting and granulation?

Composting Moisture

After Dewatering Moisture


Suitable Moisture for Better Organic Fertilizer Composting

In general, there are two choices for you. For one thing, pave dry materials under the organic fertilizer composting piles, such as straw, leaves, corn cobs, etc. For another, using dewatering machine directly. This can remove water from organic fertilizer material quickly. And after dewatering, the moisture can decrease to 30%- 40%. Why should you need to remove the moisture from these material?

Because excessive water (over 60%) will block the transport of oxygen, which is necessary for aerobic fermentation of organic waste. While too low water content (below 40%) also can not support the activity of composting bacteria. So it is advisable to keep the moisture content of materials at 40%-60%.

Ideal Moisture for Organic Fertilizer Granulation

In order to turn compost into organic fertilizer pellets successfully, you also need to pay attention to water content before granulation. Then what is the optimum feeding water content of material for organic fertilizer granulation? 20-40%. But how to adjust moisture content for better organic fertilizer granulation? Generally, you don’t need to do anything extra. Why? Because composting is a temperature rising, which will evaporate water continuously. And after composting, the moisture content of raw materials is 30%, which is suitable for making fertilizer pellets.

Which Granulation Process is Suitable for Making Organic Fertilizer Pellets?

Then how do you produce high quality organic fertilizer pellets? Different granulation process can make different quality granules. So customer from Singapore wanted to know which granulation process is suitable for this?

Wet Granulation Method to Make Organic Fertilizer

If you choose wet granulation process to make organic fertilizer, there are three organic fertilizer granulator machine for your choice. New type organic fertilizer granulator, disc pelletizer and rotary drum granulation machine. When you use these machines to make fertilizer, you need to add water to 45%-50%. Because they all use water to agglomerate pellets. Hence, drying and cooling these granules after granulation is necessary. It is a complicated process to make organic fertilizer.

Dry Granulation Method for Organic Fertilizer Production

There are two machines adopting dry granulation process: double roller granulator anf flat die pellet mill. Because the customer from Singapore wanted to make organic fertilizer. Hence, the flat die pellet mill is the best choice. It can make cylindrical pellets with a diameter of 2-8mm to meet different needs. What’s more, you cannot dry and cool these pellets after granulating. It adopts extruding material to shape them, which decreases your cost about drying and cooling.

What Other Equipment can Upgrade your Quality of Organic Fertilizer Granules?

Finally, this Singaporean customer wanted to buy an organic fertilizer granulation line to process his materials. So we recommend other ferilizer equipment to help him improve granules quality. Before granulating, besides composter, crusher and mixer are important as well. Meanwhile, drying and cooling machines are also essential to prevent sticking. And the screener can help you distinguish qualified pellets from the unqualified. Finally you need to use coating and packaging equipment to make fertilizer easier to storage and transport. Anything else? Conveyor belt is necessary to link these fertilizer equipment.
