The Double Roller Granulator Machine is an advanced fertilizer pelletizing equipment that uses extrusion technology to transform dry powder materials into compact and uniform granules. It is designed for fertilizer manufacturers who require an efficient granulation solution with a simple processing flow and flexible material adaptability.
Unlike traditional wet granulation equipment, the roller granulator forms particles through mechanical pressure without adding large amounts of water. This dry granulation method reduces the dependence on drying equipment and is suitable for producing various fertilizer products with different formulations.
The machine is widely applied in organic fertilizer plants, compound fertilizer factories, NPK fertilizer production lines, and agricultural resource recycling projects. It can work together with crushing machines, mixers, screening equipment, and automatic packaging systems to create a complete fertilizer pellet production process.
Applications
The Double Roller Granulator Machine is commonly used in:
Organic Fertilizer Manufacturing
Processes composted organic materials into granular fertilizer products for agricultural applications.
Compound and NPK Fertilizer Production
Produces fertilizer pellets according to different nutrient formulas by compressing mixed raw materials.
Fertilizer Processing Plants
Provides a reliable granulation solution for commercial fertilizer manufacturers requiring continuous production.
Recycling-Based Fertilizer Projects
Supports the conversion of suitable agricultural and industrial resources into valuable fertilizer products.
How It Works: Extrusion Granulation Process
-
Raw Material Preparation
Fertilizer ingredients are crushed, mixed, and prepared according to the required formula.
-
Feeding and Compression
Materials enter the extrusion chamber and are compressed between two counter-rotating rollers.
-
Pellet Formation
The compressed material forms sheets or blocks, which are then processed into smaller fertilizer particles.
-
Screening and Collection
Qualified granules are separated through screening equipment, while unqualified materials can be recycled.
