The non-drying double-roller extrusion granulator process offers versatile powder processing capabilities without requiring material humidification or heating. This efficient system directly processes materials into particles suitable for both organic and inorganic fertilizers, as well as feed applications.

1. Add qualified raw materials into the mixer according to ratio requirements and mix evenly
2. Transport to disc feeder, removing metallic substances during transportation
3. Material enters extrusion granulator and is forced between two pressure rollers to form flakes
4. Flakes are broken into pieces by coarse crusher and sieved
5. Semi-finished products are transported to finished screening machine
6. Fine particles return to disc feeder; large particles are crushed and returned
7. Qualified products are transported to automatic packaging scale for weighing, packaging, and storage

• No heating or humidification required - saves investment and energy
• Suitable for heat-sensitive materials like ammonium bicarbonate and organic fertilizers
• No wastewater or gas emissions - environmentally friendly
• Short process, easy operation, automated production control
• Flexible raw material requirements with wide source availability
• Production flexibility for special fertilizer batches
• Uniform particle size distribution without segregation
• Customizable particle shapes with optional rounding
