Roller compactor WP 120 Pharma

Laboratory and pilot production machine for the pharmaceutical industry

With the introduction of the WP 120 Pharma, Alexanderwerk offers a roller compactor designed to meet the highest requirements and standards in pharmaceutical research and development. On this machine small amounts of as little as 5 g to a maximum up to 40 kg/h (Lactose) can be processed with the standard roller width of 40 mm into granulates of varying sizes. This enables realistic and fully controlled production conditions when processing special products, producing small batches in laboratory or at the lower production levels.

Because of its modular design, the process technology can be almost completely disassembled without special tools. Due to its canter lever bearing design the rollers can be easily cleaned or replaced. The mobile design provides great flexibility during compaction feasibility studies and allows an easy maintenance.

The WP 120 Pharma is designed to meet cGMP and its mobility is ensured due to its compact design and fully integrated control and operator panel. Moreover, previously determined process parameters can easily be scaled up to larger production machines.
