Recycling in General

Typical applications are e.g.:
Manufacture of pellets from reclaim, e.g. PVC cable or PE sheet reclaim,
irect recycling, e.g. for the manufacture of PET fiber, PET sheet, PE blown film and nonwovens

  • Typical materials: PE, PP, PS, PET, PA 6, PA 66, PVC
  • Common throughputs up to 3.000kg/h
  • Filtration finenesses down to 20µm

Recycling places particularly high demands on the efficiency and flexibility of filtration systems. Since contamination level and particle size are constantly changing, the filtration system must react quickly to changes in the process, and fast changes of filter elements must be possible. Gneuss Filtration Systems react automatically to changing contamination levels, so that efficient filtration without disturbances is always guaranteed. In addition, the fully-automatic operation of the RSFgenius permits high throughput levels of contaminated materials. Last but not least, the RSFgenius is the perfect filtration system for direct recycling e.g. the direct manufacture of staple fibre, non-wovens, sheet etc. from reclaim.

The advantages of Rotary Filtration

  • Improved product properties
    Due to process- and pressure-constant operation, finer filtration of the melt can be achieved. This guarantees constant high quality and high line availability.
  • Short dwell time of the melt in the filtration system
    Due to the optimum rheological design of Gneuss Filtration Systems, the dwell time of the melt in the system is reduced and thus thermal stress is avoided.
  • Low operating costs
    With the fully-automatic filtration of the RSFgenius – with its high pressure cleaning of filter elements – screens are automatically re-used 100 to 400 times (depending on the filtration fineness) without any additional costs.
  • No production interruptions, no machine downtime
    Changing screens of Gneuss Rotary Filtration Systems does not have any influence on the production process, so that quality variations and strand breaks can be avoided.
  • Fully enclosed design
    Due to the fully enclosed design of the RSFgenius any influence from air during the filtration process is avoided, so that critical materials like PET, POM, PA etc. can be processed very well. Danger to the personnel and environment is excluded at all times.
