Designed specifically for small-to-medium mineral fertilizer processing and specialty plant nutrition producers, the Roller Press Mineral Fertilizer Pelletizing Line (1-5 T/H) provides an adaptable, binderless compaction solution tailored to variable feed rates. Unlike standard wet-granulation lines that demand massive capital investment in fuel-burning drying drums, this line utilizes room-temperature mechanical hydraulic extrusion to compact abrasive mineral powders—including ammonium sulfate, potassium nitrate, phosphate rock, and gypsum—into high-strength, water-soluble spherical or oval pellets.

This complete turnkey unit integrates precision loss-in-weight batching feeders, dynamic twin-shaft mixers, heavy-duty double roller press granulators, multi-deck rotary sizing screens, automated undersize recycling bucket elevators, and a semi-automatic packing machine. Built with modular scalability, operators can easily adjust production outputs between 1 and 5 tons per hour depending on raw material characteristics and market demands. As a dedicated factory supplier, Gofine Machine equips the extrusion rolls with custom-molded, work-hardening alloy steel sleeves, ensuring exceptional wear resistance against severe mineral abrasion while lowering total energy consumption by up to 35%.
