Ten Things You Need To Consider When Choosing And Installing A Roller Press System

Compacting your powder into briquets or producing granules with a roller press system can make both you and your customers happy. The briquets and granules are easier to handle than powders — they're much less dusty, don't segregate by size, shape, ordensity, and provide several other benefits as well. But selecting the right rollerpress system for yourapplication and completing the installation is a complex process. After introducing you to some roll compaction and roller press basics, this article details 10 things you need to consider when choosing and installing a rollerpress system.

Roll compaction is a form of high-pressure agglomeration. The method requires a roller press, which exerts mechanical pressure on a powder or other dry bulk material as it's forced between two counter-rotating rolls. This pressure compresses the material into compacts, which are either briquets or a sheet that's subsequently passed through a mill to produce granules.

The latter process, called compaction-granulation, offers advantages over wet granulation processes. In many cases, the dry process requires no liquid binder. It costs less to operate, requires less and simpler equipment, and can handle moisture-sensitive materials.
