The POLYGRAN® roller compactor is the entry level Gerteis roller compactor. With many of the unique roller compactor technologies of the PACTOR® range included, the POLYGRAN® offers outstanding value for money for such a sophisticated roller compactor that will deliver excellent dry granulation results. With a capacity of 500g up to 200kg per hour, the POLYGRAN® is suitable for both development and production environments.
POLYGRAN® roller compactor features:
Simple but accurate feed system to the rollers to ensure consistent dosing of powder to the rollers
Angled compaction rollers to allow feed consistency, constant ribbon density and minimisation of temperature gain
Free floating gap design and in-process force control producing a constant density ribbon
Large roller diameters to produce a longer dwell time in the nip area
Superior punch & die roller design to provide a constant density over the ribbon width and to virtually eliminate fines (no recirculation required!)
Simple but effective granulating oscillating mill with adjustable screen clearance, to produce a consistent and controllable particle size distribution
Full instrumentation with critical quality process parameter data-acquisition
Full machine calibration
Reduced number of interchangeable parts for easy disassembly and reassembly
