Working principle

A double roller granulator is an equipment that uses dry granulation technology to make powder or loose materials into particles. Its working process mainly includes two stages: extrusion and granulation, which are closely connected and work together to complete the conversion from powder to particles. Here is a specific introduction:

• Squeezing stage: After the material enters the double roller granulator, it is first strongly compressed, air is discharged, and the distance between materials is close enough to generate various attractive forces such as van der Waals force, adsorption force, crystal bridge, and embedded connection. These forces are the key to forming particle strength. Without the addition of adhesive, the intermolecular forces of the material itself are sufficient to form sturdy blocks. The double roller granulator does not require the addition of adhesive, simplifying the process and reducing energy consumption.
• Granulation stage: The cake material formed by extrusion is further crushed and screened, and particles that meet the size requirements are screened out, while the unqualified parts may be recycled back to the system for re granulation. This process of the Double Roller Granulator ensures the quality and consistency of particles, reducing energy and material waste.

Overall, the double roller granulator is an efficient, energy-saving, and environmentally friendly granulator, especially suitable for applications where hard particles can be formed by the intermolecular forces of the material itself without the need for adding adhesives. Its concise working process and numerous technological advantages make it have important application value in multiple industrial fields.For more information, please contact us by sending an inquiry today!
