Roller Compaction & Granulation Technology

This video requires you to register/login before continuing.

 

The compaction and granulation of chemical materials is an important part of the chemical industry. This is because it increases the capability to store and transport the material, especially if that material is hazardous. This webinar focuses on the processes and machines used to accomplish the compaction and granulation of chemical material. Here are some basic definitions of compaction, granulation, and briquetting. For more information, be sure to watch the full webinar. You can also click here if you wish to learn more about Hosokawa’s individual products.


Compaction


Compaction is the process of turning a powder into a single solid material, or flake. This is accomplished through a process called “densification,” which uses a controlled feed to push powders through a chamber containing to counter-rotating rollers, densifying the material as it passes through the rollers.


Granulation


Granulation is the process of turning powder into grains. This process makes use of a granulator, which turns the powder into grains that are no more than 0.2 mm to 4 mm in size.


Briquetting


Briquetting is another “densification” process, only this turns the material into separated “briquettes,” rather than one large “flake.” This process is also completed using a series of counter-rotating rollers, only these rollers have grooves in them, which give the briquettes their shape.
