Process & Application:

A roller compactor generally consists of three major units:

• A feeding system, which converts the powder to the compaction area between the rolls.
• A compaction unit, where powder is compacted between two counter rotating rolls to a ribbon by applying a force.
• A size reduction unit, for milling the ribbons to the desired particle size.
• The most important parameter in the dry granulation process is the force applied on the powder compacted between two rolls.
• The applied force is expressed in kN/cm, being the force per cm roll width.
