The Double Roller Extrusion Granulator Machine is a dry granulation equipment designed for producing uniform fertilizer pellets through high-pressure extrusion technology. Unlike traditional wet granulation methods, this machine does not require additional drying processes, making it a practical solution for fertilizer manufacturers seeking a simplified and energy-efficient granulation process.

The roller extrusion granulator is widely used in organic fertilizer production, NPK fertilizer manufacturing, compound fertilizer plants, and chemical fertilizer processing industries. It can process various dry materials and can be integrated with crushing, mixing, screening, and packaging equipment to form a complete fertilizer production line.

The double roller granulator adopts a dry granulation process, eliminating the need for a drying stage after pelletizing. This helps simplify the production process and reduces equipment requirements for fertilizer manufacturing.

The two rollers apply continuous pressure to compress fertilizer materials into compact particles. The extrusion process improves granule density and provides stable pellet formation.

After extrusion and screening, the machine produces fertilizer particles with relatively uniform size, making them suitable for transportation, storage, and agricultural application.

Compared with complete wet granulation systems, the roller extrusion granulator has a compact structure and can be easily integrated into fertilizer production lines with mixers, crushers, screening machines, and packaging systems.

The Double Roller Extrusion Granulator Machine is widely applied in:

Used for converting processed organic materials into granular fertilizer products with improved handling performance.

Suitable for producing compound fertilizer pellets with different nutrient formulas.

Applied in medium and large fertilizer manufacturing projects requiring efficient dry granulation solutions.

Can be used for processing recycled fertilizer materials and dry organic resources.

1. Material Preparation
Raw materials are crushed and mixed according to the fertilizer formula.

2. Feeding Process
Prepared powder materials enter the extrusion chamber through the feeding system.

3. Roller Extrusion
Two rotating rollers compress the materials under high pressure to form compact sheets or granules.

4. Crushing and Screening
Extruded materials are crushed and screened to obtain qualified fertilizer particles.

5. Packaging
Finished granules are transported for storage or automatic packaging.
