Roller compactor for pharmaceutical and chemical industries
Optimize your powder processing with precision compaction and consistent granule quality, reducing particle stress and generating fewer fines through an innovative multi-stage granulation process.

Compacts and Granulates Powders into Consistent Flakes
The Roller Compactor by Germany’s Alexanderwerk, represented by AUSTAR, excels in transforming powders into high-quality flakes and granules, crucial for pharmaceuticals and chemicals. Featuring a vertical roller setup and integrated 3-stage granulation, it minimizes product stress and fines. The Combi-Vent-Feeder ensures effective air venting, promoting flake consistency. The included standard vacuum deaeration system, initially invented by Alexanderwerk, enhances process efficiency. With applications spanning from tablets to silica gel, the compactor supports continuous high-speed operations within processing departments. This machine’s diagonal design doubles granulator output capacity, while stainless steel construction options offer robust chemical resistance. Meeting GMP standards, it integrates seamlessly, offering low-maintenance operation for demanding production lines.
