Technical Features Of Double Roller Granulator

  • Unique Double Roller Design: The Double Roller Granulator is equipped with two counter-rotating rollers that exert pressure on the raw materials, ensuring efficient and uniform granulation.

  • Adjustable Roller Gap: The roller gap can be easily adjusted to control the size and density of the granules produced, allowing for precise customization based on specific requirements.


  • High Granulation Efficiency: The Double Roller Granulator offers high granulation efficiency, thanks to its compacting and shaping action that enhances the agglomeration of the raw materials.

  • Wide Range of Capacity: It is available in various models with different production capacities, allowing for scalability and adaptation to specific production requirements.

  • Robust Construction: The Double Roller Granulator is built with sturdy materials, ensuring durability and long-lasting performance even in demanding industrial environments.

Working Principle Of Double Roller Granulator

The Double Roller Granulator operates based on the principle of extrusion and granulation. The raw materials are fed into the gap between two counter-rotating rollers. As the rollers rotate, they exert pressure on the materials, forcing them to undergo plastic deformation.

During this process, the fine powders or small particles are compacted and adhere together to form larger granules. The compacting action also helps in shaping the granules. The size and density of the granules can be adjusted by controlling the roller gap.

The rotation of the rollers moves the granules forward through the machine. As they move, the granules are further densified and rounded due to the continuous pressure and shaping effect of the rollers.

The granules produced by the Double Roller Granulator are uniform in size and have good strength. They can be further processed, such as drying or coating, or used directly as a final product.

The working principle of the Double Roller Granulator ensures efficient and uniform granulation, offering advantages such as controlled granule size, improved handling properties, and enhanced product quality in various industries.
