Granulation is a core component of NPK compound fertilizer production lines, and the selection of granulation equipment directly determines product quality and production efficiency. Double roller press granulators, with their strong adaptability, low energy consumption, and excellent forming effect, have become the most widely used core granulation equipment in this production line, perfectly meeting the needs of compound fertilizers with multiple nutrient ratios and large-scale production.
Its high adaptability to NPK compound fertilizer production lines stems from its unique working principle. Without high-temperature drying, the NPK raw materials are uniformly mixed and then directly pressed into granules through double-roller extrusion. This retains the activity of nitrogen, phosphorus, and potassium nutrients while achieving rapid and uniform granule forming, preventing nutrient loss.
Its advantages are significant: low energy consumption, stable operation, adaptability to various raw material ratios, forming rate exceeding 90%, high granule strength, resistance to clumping, and ease of storage, transportation, and application; it is also simple to operate and maintain, adaptable to continuous production line operation, and improves overall production efficiency.
When using this equipment, please note the following: Adjust the extrusion pressure and roller gap according to the compound fertilizer ratio to ensure uniform granules; ensure the raw materials are thoroughly mixed to avoid impurities, which could lead to equipment wear and poor granulation.
In summary, the double roller press granulator, with its advantages of high adaptability, high molding rate, and low energy consumption, has become an indispensable core piece of equipment in NPK compound fertilizer production lines, helping to achieve large-scale and standardized compound fertilizer production.
