Roller Compacted Ribbon Mill

  • Which Roller Compaction Model Best Fulfills Your Process Needs

    Sep 21, 2020· This System enables the best compression or tamping of the powder, and inherent deaeration of the feed powders so that the cantilevered rolls can produce a consistent compacted ribbon. Both IR and CCS-Series models utilize the world-class FitzMill ™ to mill and granulate the ribbon.

    More specifically, the roller compaction method provides an alternative to 'slugging', in which dry powders are aggregated into large compacted slugs of powder blend. Instead, roller compaction compresses the material into a solid, densified 'ribbon' sheet that is easier to mill down into granules.

    Apr 23, 2007· Both compact hardness and tensile strength drop dramatically when microcrystalline cellulose is roller compacted to higher SF of 0.64 or 0.84. When the microcrystalline cellulose is roller compacted, it undergoes volume reduction as the ribbon is compressed and pressure must be increased to form ribbons with a higher SF.

  • Roller compaction press force, gap on ribbon and granule

    The applied press force during roller compaction is called the 'specific press roller force', specified in kN/cm; the minimum distance between the press rollers is the gap [mm]. Force and gap are the main drivers affecting ribbon density in roller compaction. Further, ribbon density is the main determining factor for granule properties.
