Generally speaking, it is quite simple to manufacture all kinds of fertilizer pellets if you adopt the method of dry granulation, including bio fertilizer, NPK fertilizer and animal waste fertilizer. You can pour your raw materials into the feeders of our dry granulator as long as their water content is in the range between 5% and 10%. However, please control the speed of feeding. If you feed too much fertilizer powder at once, it is likely to block the dry granulating machines, weighing on the granulation rate.
In fact, a dry granulator works in a way of pressing fertilizer powder by a huge extrusion force. While our flat die granulation machine and dry granulator roller compactor work on the principle of dry granulation, they have some differences in their working principles. Then, how exactly do they work to turn fertilizer powder into small granules?
