MINI-PACTOR® Roller Compactor

Advanced Dry Granulation Technology
The MINI-PACTOR® Roller Compactor is designed for both laboratory development and for small to medium scale production runs. Roller Compaction is a fully continuous granulation technology; the MINI-PACTOR® has capacities from 10 grams per trial up to 100kg per hour, and with harmonisation with the other PACTOR® designs by having identical roller diameters, scale-up is simple and quick, avoiding risks and reducing costs.

Unique Gerteis® Roller Compaction features

• Consistent feed system to the rollers with torque control of the screw feeder and tamp auger to ensure precision dosing of powder
• Angled compaction rollers to allow feed consistency, constant ribbon density and to minimise temperature gain.
• Free floating gap design and in-process force control producing a constant density ribbon
• Large diameter rollers 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!)
• Three stage milling process with the 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
• Standard containment performance of 3 µg/m³ Time Weighted Average

• WIP/CIP cleaning,
• Enhanced containment performance
• Build in PAT control systems
• Press roller cooling/heating
• Vacuum de-aeration.
• Different roller surface designs
• Separate feed funnel for small quantities.
• Industrial PC solutions
