Roller compactor PP 175

Compaction machine for the chemical industry

The PP 175 from Alexanderwerk is the perfect roller compactor designed to meet all requirements and standards of economical compaction and is capable of achieving a throughput of approximately 2,000 kg/h with a roller diameter of 175 mm.

The machine is equipped with the patented Combi-Vent-Feeder®, improving the de-aeration capability and allowing more raw material to be processed in a given period, resulting in a more efficient, and therefore more profitable operation.

Through the double-sided bearing of the rollers and a robust construction, a maximum pressure force of 30 kN/cm can be delivered. Previously determined process parameters can easily be scaled up to larger production machines of the Alexanderwerk machine series. In addition, a great flexibility as well as adaptability to different granule sizes is achievable with the PP 175.
