Double Roller Press Or Extrude Fertilizer Production Line For Chemical Fertilizer

Extrusion Granulation Solutions

Our Turnkey Double Roller Press Granulation Line provides a highly efficient, dry-compaction solution designed specifically to eliminate the high energy costs and thermal degradation issues faced by compound fertilizer manufacturers:

• Zero-Drying Technology Cuts Energy by 50%: Operating entirely via room-temperature mechanical compaction, this line requires no water or steam. By completely eliminating bulky rotary dryers and coolers, it slashes your fuel and electricity bills by over 50% and reduces factory floor space requirements by 30–40%.

• 100% Nutrient & Formula Integrity: Because the process runs at ambient temperature, it preserves the bio-activity of heat-sensitive micro-elements, amino acids, and microbes. Paired with our automated PLC batching, crushing, and mixing systems, it guarantees exact, uniform NPK ratios in every batch.

• High-Hardness Pellets Prevent Caking: The heavy-duty alloy rollers exert extreme linear pressure to form ultra-dense granules with moisture levels below 2%. This high physical strength prevents crumbling, eliminates messy product dust, and stops fertilizer caking during long-term warehouse storage and transit.

• Closed-Loop Automation with Zero Waste: The entire 6-stage process—Batching, Crushing, Mixing, Granulating, Screening, and Packaging—is fully integrated. A closed-loop conveyor automatically returns fine powders for re-pressing, achieving a 95% granulation rate with zero raw material waste and requiring only 2–3 operators to run the entire line.
