The Roller Extrusion Granulator Machine is a dry granulation equipment designed for producing uniform fertilizer pellets without the need for drying processes. By using a pair of rotating rollers to apply pressure on prepared materials, the machine compresses powder materials into dense granules with consistent shape and size.
This fertilizer granulator is widely used in organic fertilizer production, NPK fertilizer manufacturing, compound fertilizer processing, and chemical fertilizer plants. Its compact structure, low moisture requirement, and simple production process make it an efficient solution for fertilizer manufacturers looking to produce high-quality granular products.
The equipment mainly consists of a feed inlet hopper, extrusion rollers, gearbox, and discharge outlet hopper. Raw materials enter through the feeding system, are compressed between the rollers, and are discharged as formed granules for further screening and packaging.
Product Highlights
Dry Extrusion Granulation Process
The roller extrusion granulator adopts a dry granulation method, reducing the need for additional drying equipment after granulation. This process helps simplify the production flow and reduce energy consumption during fertilizer processing.
Uniform Granule Formation
The two roller system applies continuous pressure to the material, allowing powder fertilizer materials to form compact granules with improved density and uniformity. The final particle size can be adjusted according to production requirements.
Wide Material Compatibility
The machine is suitable for processing various fertilizer materials, including:
- NPK fertilizer raw materials
- Compound fertilizer powder
- Organic fertilizer materials
- Mineral fertilizer ingredients
- Potassium fertilizer and other dry materials
It is commonly integrated into fertilizer production lines where dry granulation is required.
Compact Structure and Easy Operation
The roller extrusion granulator features a compact design with simple operating principles. The gearbox provides stable power transmission, while the feeding hopper ensures continuous material input during production.
Flexible Production Integration
The equipment can be combined with crushers, mixers, screening machines, and packaging systems to create a complete fertilizer manufacturing process.
Applications
Organic Fertilizer Production
Used for granulating processed organic materials into convenient fertilizer particles for storage, transportation, and agricultural application.
NPK Fertilizer Manufacturing
Suitable for producing compound fertilizer granules with different nutrient formulas by compressing mixed powder materials.
Industrial Fertilizer Processing
Applied in fertilizer factories, chemical fertilizer plants, and agricultural resource recycling projects requiring efficient dry granulation solutions.
Working Process
Material Feeding
Prepared fertilizer powder enters the machine through the feed inlet hopper.
Roller Extrusion
The rotating rollers compress the material under high pressure to form dense fertilizer sheets or granules.
Granule Discharge
The formed materials are discharged through the outlet hopper.
Screening and Packaging
Qualified fertilizer particles are collected, while oversized materials can be recycled for further processing.
