Roller Compactor PP 350

Compaction machine for the chemical industry

The PP 350 from Alexanderwerk is the perfect roller compactor designed to meet all requirements and standards of an economic compaction. The PP 350 completes the series below the PP 500 and achieves a throughput up to 15,200 kg/h with a roller diameter of 350 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 60 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 350.
