In the field of fertilizer processing, dry granulation technology using fertilizer compaction machines has become a key link in promoting green industrial upgrading and improving production efficiency, thanks to its unique advantages. Compared to wet granulation, this technology does not require the addition of water and binders, achieving raw material shaping through mechanical extrusion. Its importance is reflected in several core dimensions, including environmental protection, raw material adaptability, and product quality.
Environmental upgrading is one of the core values of dry granulation. Wet granulation requires a subsequent drying process, which consumes a lot of energy and easily generates exhaust gas pollution. Dry granulation, however, eliminates the need for drying, significantly reducing energy and water consumption while minimizing pollutant emissions, perfectly aligning with green production policies.
Expanding the range of adaptable raw materials enhances industrial flexibility. Dry granulation is more compatible with varying raw material moisture content and composition. Whether it’s organic raw materials such as livestock and poultry manure compost or straw powder, or inorganic raw materials such as chemical fertilizer intermediates, efficient shaping can be achieved through fertilizer granules compaction machines.
Ensuring product quality enhances application value. The dry granulation process is gentle, preserving the nutrient components in the raw materials to the greatest extent possible, avoiding nutrient loss caused by high-temperature drying. At the same time, the granules formed by fertilizer extrusion technology have uniform hardness and good solubility, facilitating storage, transportation, and application. This technology is suitable for large-scale planting scenarios such as mechanical fertilization, improving fertilizer application efficiency and nutrient conversion rates, and providing support for improving the quality and efficiency of agricultural production.
