Dry granulation has become an essential process for manufacturers seeking lower energy consumption, stable productquality, and environmentally friendly production. Among various solutions, the double roller dry granulator stands out as a reliable and cost-effective roller compaction granulation system.
In this article, we explain how double roller dry granulation works, its key advantages, and why more industries are adopting this technology.
A double roller dry granulator, also called a double roller compactor granulator or twin roller granulator, is a type of dry granulation machine that forms granules by compressing powder between two counter-rotating rollers.
Unlike wet granulation, this process:
1.Requires no liquid binders
2.Requires no drying system
3.Preserves material stability
Dry powder is evenly fed into the roller press granulator through a controlled feeding system to ensure uniform compaction.
Two rollers apply high, adjustable pressure to compact the powder into dense flakes. This step determines granule density and strength.
The flakes are processed by a flake crusher granulator and screened to achieve uniform granule size.

Q1: What is a double roller dry granulator used for?
A double roller dry granulator is used to convert fine powders into uniform granules through roller compaction. It is widely used in fertilizer, chemical, pharmaceutical, food additive, and battery material industries.
Q2: Does a double roller dry granulator require drying?
No. The dry granulation process does not require liquid binders or drying equipment, which helps reduce energy consumption and production cost.
Q3: What materials are suitable for dry granulation?
Dry granulation is ideal for heat-sensitive and moisture-sensitive materials, including chemical powders, fertilizers, pharmaceuticals, and battery materials.
Q4: How is granule size controlled in a double roller dry granulator?
Granule size is controlled through adjustable roller pressure, roller gap, and the crushing and screening system.
Q5: What are the advantages of roller compaction granulation compared to wet granulation?
Roller compaction granulation offers lower energy consumption, no wastewater discharge, simpler operation, and more stable material properties.
