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.
