How to Make Organic Fertilizer Granules in Singapore

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?

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.

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.

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.
