(FAQ)What is fertilizer granules compaction technology?

Fertilizer granules compaction technology is a mainstream physical forming process in dry granulation. It relies on pure mechanical pressure to form powdered fertilizer, eliminating the need for high-temperature and humid processes. It is a core technology for modern refined and low-carbon fertilizer production, widely applicable to the granulation of single-element fertilizers, inorganic compound fertilizers, and organic-inorganic compound fertilizers. The core of this technology is the principle of room-temperature dry forming, resulting in a simple and efficient production process. Uniformly proportioned powdered fertilizer raw materials are fed into the equipment, where stable mechanical pressure is applied through a roller press structure, causing the loose powder to compact and solidify. After screening and shaping, uniformly sized solid granules are formed. The entire process requires no water or chemical additives, eliminating cumbersome drying and cooling processes, significantly simplifying the production process. Compared to traditional processes, fertilizer granules compaction technology offers significant advantages. Operating at room temperature throughout completely avoids nutrient decomposition and volatilization caused by high temperatures, preserving the original nutrient components of the fertilizer to the greatest extent and ensuring stable fertilizer efficacy. Meanwhile, the technology is highly adaptable, capable of processing various materials such as urea, phosphate and potassium fertilizers, and micronutrient fertilizers, supporting flexible formulation adjustments to meet various customized production needs. Furthermore, the extruded fertilizer granules have uniform hardness, are not prone to pulverization, produce no dust, have low storage and transportation losses, and are convenient for field application. The entire production process is pollution-free with lower energy consumption, effectively controlling production costs and aligning with green agriculture and low-carbon production standards, making it the preferred technology for large-scale, standardized fertilizer production.
