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.

The design and construction are orientated on the strict requirements of pharmaceutical industry and provide the following advantages:

  • cGMP design consistent separation between process material and technical equipment
  • Rollers in cantilever design integrated two-stage rotor fine granulators in Diagonal-Design® made completely of high quality stainless steel, non-metallic parts FDA approved
  • Automated PLC
  • URS-conformity as required
  • Tool free disassembly
  • Easy and accurate Scale-up mobile machine base


  • micro compaction unit for small quantities
  • mini compaction unit with smaller screw (25 mm Ø) and narrower rollers (25 mm width)
  • circumferential side seals WIP (Wash in Place) 21 CFR Part 11
  • containment solution with isolator technology
  • additional roller surface (smooth/grooved/knurled/squared or a desired combination)
  • pressure water cooling
  • hopper with level limit switch
  • pneumatic conveyor for raw material/final granule
  • through-the-wall-design
  • AGS (Automatic Granulation System
  • Remote Access
