The Roller Compaction Granulation System is an advanced dry granulation technology used to convert powder materials into uniform granules through high-pressure extrusion. Unlike traditional wet granulation processes, this system does not require water, binders, or a drying stage, making it highly efficient and environmentally friendly.
With the increasing demand for high-quality granules in industries such as fertilizers, pharmaceuticals, chemicals, and food processing, the Roller Compaction Granulation System has become one of the most reliable and cost-effective solutions for large-scale industrial production.
The roller compaction granulation system offers exceptional flexibility and is widely used across various industries, adapting to the processing and production of different raw materials.
In fertilizer manufacturing, roller compaction technology is commonly used to produce various types of granulated fertilizers.
Typical products include:
NPK compound fertilizers
Potassium sulfate fertilizer
Ammonium sulfate fertilizer
Potassium chloride fertilizer
Organic and bio-organic fertilizers
Micronutrient fertilizers
The system can produce fertilizer granules with varying elemental content by adjusting the feed ratio of raw materials, enabling diversified production and significantly reducing caking problems.
The chemical industry frequently uses roller compaction granulation systems to convert fine powders into stable granules that are easier to transport, store, and process.
Typical chemical products include:
Detergent powders
Catalysts
Pigments such as titanium dioxide
Chemical additives
Battery materials
Granulation improves the density and handling properties of these materials while maintaining chemical stability.
The Roller Compaction Granulation System plays a crucial role in pharmaceutical production, especially for moisture-sensitive or heat-sensitive active ingredients.
Common applications include:
Tablet and capsule granules
Traditional herbal medicine granules
Antibiotic powders
Nutraceutical formulations
Dry granulation helps preserve the activity of pharmaceutical ingredients and ensures consistent particle size distribution for downstream processing.
The system is also widely used in the food and nutraceutical industries.
Typical products include:
Protein powders
Instant beverage powders
Milk powder granules
Nutritional supplements
Flavoring agents
Granulation improves solubility, flowability, and product stability during packaging and transportation.
In metallurgical and environmental industries, roller compaction is used to recycle industrial powders and waste materials.
Applications include:
Metal powders
Mineral powders
Industrial dust recycling
Smelting additives
This process converts fine powders into dense granules, reducing dust pollution and improving material utilization.
A complete Roller Compaction Granulation System typically includes several integrated pieces of equipment working together to ensure continuous production.
Includes:
Screw feeder
Storage hopper
This system ensures stable and continuous feeding of powder materials into the granulator.
A mixer is often used before granulation to ensure uniform blending of different raw materials or additives.
Common types include:
Horizontal mixer
Ribbon mixer
Double shaft mixer
This is the core equipment of the system.
Working principle:
Powder materials are fed between two counter-rotating rollers
High pressure compresses the powder into flakes or sheets
The sheets are crushed and processed into granules
Roller gap and pressure can be adjusted to control granule size and density.
After compaction, the formed sheets are crushed into granules of the desired size.
Typical equipment:
Flake crusher
Chain crusher
A vibrating screen separates qualified granules from oversized or undersized particles.
Oversized particles are returned for re-crushing.
Cage crusher & Vibrating screener & Belt conveyor
Finished granules are automatically weighed and packed using:
Automatic packing machines
Bagging systems
Palletizing systems
The Roller Compaction Granulation System offers multiple technical and economic advantages.
Dry granulation eliminates the need for water and drying equipment, reducing production complexity and energy consumption.
Materials that degrade under heat or moisture can be safely processed using roller compaction.
Compared with wet granulation systems, roller compaction requires:
Less equipment
Lower energy consumption
Reduced maintenance costs
The system produces granules with:
Consistent density
Good flowability
High mechanical strength
These properties improve product quality and downstream processing efficiency.
Roller compaction granulators can operate continuously, making them ideal for large-scale industrial production.
Because no liquid binders or solvents are used, the process generates:
No wastewater
Less dust emissions
Reduced environmental impact
The Roller Compaction Granulation System can process a wide range of powder materials.
Ammonium sulfate
Ammonium chloride
Potassium chloride
Potassium sulfate
Urea powder
Monoammonium phosphate (MAP)
Diammonium phosphate (DAP)
Titanium dioxide
Sodium carbonate
Detergent powder
Chemical catalysts
Additives
Active pharmaceutical ingredients (API)
Lactose
Starch
Herbal powders
Protein powder
Milk powder
Instant beverage powders
Nutritional supplement powders
