Roller Press Granulator Production Line: The Dry Granulation Revolution Without Drying

In multiple industrial fields such as fertilizers, chemicals, and minerals, the granulation of powdered materials has long faced challenges like high energy consumption and complex processes. The emergence of roller press granulator production lines has completely changed this landscape. This innovative dry granulation technology can transform powder into high-strength granules through high-pressure physical compression alone, without adding binders or requiring drying processes, ushering in a new era of granulation technology.

Finished Granules
High-density, high-strength solid granules
Roller Press Granulation: The Miracle Created by Pressure
The core principle of roller press granulation technology is to apply extremely high mechanical pressure (typically 50-200 MPa) to powdered materials using two parallel, counter-rotating press rolls. Under immense pressure, the distance between material particles is forcibly reduced, causing plastic deformation. Atoms and molecules on particle surfaces form strong bonds under pressure, creating dense, solid sheet or strip products, which are then crushed and sized to obtain granules of the required specifications.
This purely physical granulation method offers numerous unique advantages: no liquid binders needed, avoiding subsequent drying processes; no introduction of foreign impurities, ensuring high product purity; capability to handle heat-sensitive materials without damaging active components due to high temperatures; high granule density and strength, facilitating storage and transportation.
Compared to traditional wet granulation, roller press granulation production lines can reduce energy consumption by 50-70%, water consumption by 100%, and dust emissions by over 90%. This "green granulation" technology is becoming an important choice for sustainable development.
