HUBER Wash Drum RoSF9

Efficient and reliable coarse material separation:

  • Grit from WWTPs and sewer systems
  • Road refuse and oil grit
  • Septic sludge
  • Industrial applications
  • Homogenisation of the material to be processed
  • Break-up of big aggolomerates in the material
  • Washout of all material < 10 mm
  • Clean material after coarse material washing
  • Self-cleaning screen drum
  • Different screen perforations available
  • A frequency converter allows for different rotation speeds

While wash water is added to pre-wash and homogenise the raw material within the HUBER Wash Drum in RoSF9 version, the perforated plate of the Wash Drum retains all particles > 10 mm, which are dewatered and then discharged into a skip. Since only coarse material > 10 mm is separated, the volume of the resultant residues is vastly reduced.

Virtually the complete mineral material being further treated in the down-stream COANDA Grit Washer. The resultant coarse material can then be further separated into a mineral and organic fraction by means of a coarse material washer.

The Wash Drum is also available as Sludge Acceptance Plant RoFAS version.
