Roller compactor WP 150 Pharma

Contained compaction and granulation machine

The Alexanderwerk WP 150 Pharma is especially designed as a production model which meets the highest requirements and standards of the pharmaceutical industry. With its sealing system customized for containment and a throughput of up to 150 kg/h, it is highly suited when it comes to compacting and granulation of both standard and potent products.

Moreover, the machine is equipped as standard with the patented Combi-Vent-Feeder®. Through the improved de-aeration capability more raw materials can be processed in a given period, which leads to a more efficient and therefore profitable operation.

Because of its modular design, the process parts can be almost completely disassembled without the Need of special tools. Due to its cantilever bearing design the rollers can be easily replaced and cleaned, which provides efficient and flexible production and product changeover. To ensure a compact design, the machine has a low overall height and the control system is integrated in an external control cabinet.
