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 an economic compaction. The PP 175 completes the series below the PP 250 and achieves a throughput up to 2,000 kg/h with a roller diameter of 175 mm.

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

Through the double sided bearing of the rollers and a robust construction a maximum pressure force of 30 kN/cm can be assured. Moreover, 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 guaranteed with the PP 175.
