The rapid development and widespread adoption of double roller press granulators is an inevitable result of process upgrades, policy guidance, market demand, and technological iteration. Roller press granulator produciton lines built with these granulators have become the core preferred solution for fertilizer and other granulation production fields.
This equipment adopts a room-temperature dry extrusion process, requiring no heating and little or no binder, eliminating the drying and cooling stages. Compared to traditional wet granulation, energy consumption is reduced by more than 30%, and there are no wastewater or exhaust emissions, aligning with dual-carbon goals and clean production requirements, and adapting to the increasingly stringent environmental protection environment of industrial development. Extrusion granulation production lines based on this granulator have a shorter process flow and smaller footprint. Continuous double-roller extrusion achieves a large-scale production capacity of 30 tons/hour, producing high-strength granules with a uniformity exceeding 92%, and flexible particle size adjustment, significantly reducing storage and transportation losses.
Extrusion granulation production lines have extremely wide raw material adaptability, processing various powdery materials such as organic fertilizers, NPK compound fertilizers, and mineral powders. Changing the die allows for switching granule specifications and shapes, meeting customized, multi-category flexible production needs, and significantly reducing enterprise investment and operating costs. Meanwhile, with the support of intelligent equipment upgrades, the PLC intelligent control system enables precise parameter control and remote operation and maintenance, while the modular design makes maintenance more convenient, further improving the production line's operating efficiency.
Today, extrusion granulation production lines have expanded from the fertilizer industry to fields such as chemicals, building materials, and metallurgy, adapting to the green, efficient, and large-scale production needs of various industries. Their development is an inevitable choice for industrial upgrading and a mainstream trend in future granulation production.
