High Pressure Double Roller Extrusion Granulator for Dry Extrusion Granulation

The Double Roller Extrusion Granulator Machine is an efficient dry granulation equipment designed for producing uniform fertilizer pellets from powder materials. By using a pair of high-pressure rollers, the machine compresses raw materials into dense sheets and granules without requiring a drying process, making it an ideal solution for organic fertilizer production, NPK fertilizer manufacturing, and compound fertilizer processing.

Compared with traditional wet granulation methods, the roller extrusion granulator simplifies the production process by reducing moisture requirements and eliminating the need for additional drying equipment. This helps fertilizer manufacturers reduce processing steps while improving production efficiency.

The equipment is widely used for processing various dry fertilizer materials, including organic fertilizer powder, compound fertilizer ingredients, NPK materials, and mineral fertilizer components. It can be integrated with crushing machines, mixers, screening machines, and packaging systems to create a complete fertilizer production line.

The double roller granulator adopts a dry extrusion process. Materials are compressed between two rotating rollers under high pressure, forming compact fertilizer particles without adding additional water or requiring a drying stage.

The extrusion process helps transform powder materials into granular fertilizer products with improved density and convenient storage and transportation characteristics. The final particle size can be adjusted according to production requirements.

The double roller extrusion granulator features a compact design, simple operating principle, and convenient maintenance. The feeding system and roller structure ensure continuous material processing during production.

Because the dry granulation method does not require a drying process, the production flow is simplified. This makes the equipment suitable for manufacturers seeking efficient fertilizer pelletizing solutions.

The equipment can work together with:

• Fertilizer crusher
• Mixing machine
• Screening machine
• Conveyor system
• Packaging machine

to form a complete fertilizer manufacturing system.

The Double Roller Extrusion Granulator Machine is widely used in:

Used for converting prepared organic fertilizer materials into granular products suitable for agricultural application.

Suitable for producing compound fertilizer granules with different nutrient formulas.

Provides an effective granulation solution for blended fertilizer processing.

Applicable for commercial fertilizer factories requiring continuous and efficient pellet production.

1. Raw Material Preparation
   Fertilizer powders are crushed and mixed according to the required formula.
2. Feeding Process
   Prepared materials enter the extrusion chamber through the feeding system.
3. Roller Compression
   Two rotating rollers apply pressure to compress the materials into dense sheets.
4. Granule Formation
   The compressed materials are crushed and screened into qualified fertilizer particles.
5. Packaging and Storage
   Finished granules are packaged for transportation and agricultural use.
