Organic-Inorganic NPK Compound Fertilizer Production: Granulation Technology and Equipment Matching

Against the backdrop of the compound fertilizer industry’s upgrade towards green and efficient practices, organic-inorganic compound fertilizers are becoming increasingly popular due to their dual advantages of improving soil and providing readily available nutrients. However, granulating fermented organic raw materials (such as pig manure and straw) with inorganic NPK powder is far from a simple process—problems such as high fiber content, significant differences in specific gravity, and uneven moisture content have led many production lines into a predicament of “loose granules and nutrient stratification.” Scientific granulation technology and equipment matching are key to solving this problem.
