Pharmaceutical roller compactor for granulation
Achieve precise granulation with streamlined compaction, ensuring consistent quality and efficiency in pharmaceutical powders and fine chemical products.

Compacts and Granulates Pharmaceutical Powders
The WP 150 Pharmaceutical Roller Compactor from Alexanderwerk is engineered to meet the rigorous demands of pharmaceutical and chemical manufacturing. This compact production model excels in optimizing granulation and compaction processes for pharmaceutical tablets, granulated APIs, and specialty chemical granules.
The WP 150 utilizes a vertical roller arrangement and the Combi-Vent-Feeder® system for efficient feeding and precise compaction, minimizing fine material output and ensuring batch consistency. With its single-stage granulation using the patented Diagonal-Design®, the device doubles throughput and maximizes screen utilization for optimal granule sizing.
Rated for up to 250 kg/h of granulated product, this machine suits high-speed continuous operations. Its advanced interface allows seamless control of roller gap and compaction pressure, adapting to physical product changes. Designed for pharmaceutical manufacturers and CDMOs, the WP 150 adheres to OEB5 containment standards and provides a robust solution for those requiring high precision in granulation.
Integration into existing production lines is streamlined through PLC controls and efficient air management, enhancing overall operational efficiency. Additionally, Alexanderwerk offers engineering support and customization options, ensuring that the WP 150 fits your specific production requirements.
