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 economical compaction and is capable of achieving a throughput of approximately 15,200 kg/h with a roller diameter of 250 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 60 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 350.
