The rotary drum granulator is the core equipment in fertilizer production lines. It forms powdered raw materials into uniform granules through a rotating drum. This granulation process not only enhances the physical stability of the fertilizer but also makes it easier to store, transport, and apply. As the raw materials tumble inside the drum, the addition of a suitable liquid binder helps tiny particles gradually form, eventually becoming evenly sized fertilizer granules.
However, the efficient operation of the rotary drum granulator relies on the coordination of other equipment. A chain crusher first pulverizes the raw materials to the appropriate particle size, preparing them for granulation. A drum fertilizer dryer then removes excess moisture from the granules, ensuring stable fertilizer quality. Subsequently, a cooler reduces the temperature of the granules, increasing their hardness. Finally, a screening machine sorts the finished products by size, while a packaging machine completes the final sealing process.
This complete production line offers multiple advantages. First, it significantly improves fertilizer utilization—granular fertilizers release nutrients more slowly in the soil, reducing nutrient loss. Second, granular fertilizers are less prone to caking, making storage and application more convenient. Additionally, the production line allows precise control over particle size and composition, meeting the specific needs of different crops. Most importantly, this production method reduces dust pollution, making it more environmentally friendly.
From powdered raw materials to uniform granules, fertilizer granulation technology not only enhances product quality but also provides robust support for the sustainable development of modern agriculture. As technology continues to advance, this efficient and eco-friendly production method is poised to play an increasingly vital role in global agriculture.
