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.
Product Highlights
Dry Extrusion Granulation Technology
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.
Efficient Fertilizer Pellet Production
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.
Compact Structure and Easy Operation
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.
Energy-Saving Production Process
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.
Flexible Production Line Integration
The equipment can work together with:
- Fertilizer crusher
- Mixing machine
- Screening machine
- Conveyor system
- Packaging machine
to form a complete fertilizer manufacturing system.
Applications
The Double Roller Extrusion Granulator Machine is widely used in:
Organic Fertilizer Production
Used for converting prepared organic fertilizer materials into granular products suitable for agricultural application.
NPK Fertilizer Manufacturing
Suitable for producing compound fertilizer granules with different nutrient formulas.
BB Fertilizer Production
Provides an effective granulation solution for blended fertilizer processing.
Fertilizer Processing Plants
Applicable for commercial fertilizer factories requiring continuous and efficient pellet production.
Working Process
- Raw Material Preparation
Fertilizer powders are crushed and mixed according to the required formula.
- Feeding Process
Prepared materials enter the extrusion chamber through the feeding system.
- Roller Compression
Two rotating rollers apply pressure to compress the materials into dense sheets.
- Granule Formation
The compressed materials are crushed and screened into qualified fertilizer particles.
- Packaging and Storage
Finished granules are packaged for transportation and agricultural use.
