Spheronizer R series

About the R series
The R series rotor insert is a retrofit rotor attachment for fluid‑bed combination machines developed for pharmaceutical production. Integrated into a single container, it enables pelletisation, dry powder layering, rotor granulation/suspension coating and spherical granulation while delivering narrow particle‑size distribution and high‑density pellets. Process development and optimisation are supported by ACG experts with experience across more than 1,000 formulations.

Applications

• Spheronisation / pelletisation
• Dry powder layering (powder layering)
• Solution and suspension coating (rotor granulation / suspension coating)

Features & Benefits

• Plug‑and‑play interchangeable insert retrofittable to existing fluid‑bed combination machines — extends process capability without new capital equipment
• High‑accuracy powder dosing system compatible with a wide range of formulations — precise control for layering and coating processes
• Interchangeable rotor discs covering the full application range — enables spheronisation and targeted drug layering
• Easy integration with multiple powder feeders and dosing systems — flexible configuration for different production scenarios
