ID2 & ID3 Screening Concepts

 

The ID2 and ID3 screening concepts bring innovative and technically advanced solutions to improve fine slot screening. These concepts are included in products such as the ScreenONE™ three-stage fine screening system and the FiberNET™ multi-stage pressure screen.

 

Working Principle

The ID2 and ID3 screening concepts consist of creating an intermediate deflocculation and dilution inside the screen. These features, associated with guidance of the stock inside the screen, allow us to duplicate in one screen the same conditions as for a screening system comprising screens in two or three stages.

 

Applications

  • Fine or very fine slot screening with highest efficiency,capacity and yield at best runnability
  • ScreenONE is an integrated three stage screen. It is a self contained fine slot screening plant with a very low reject rate, energy consumption for a very low overall investment.
  • ScreenTWO & TriFRactor are integrated two stage fine slot screens or Fractionators for very low energy consumption and overall investment.
  • FiberNET is a continuous tailing screen for both, stock preparation and approach flow with various specific features depending upon the applications.
  • ScreenTEK, like ScreenONE, ScreenTWO, TriFRactor with its UP-Flow design, is a modern one stage screen integrating, together with other features, the new ID2- Technology.
  • ID2-RetroFIT of existing screens needing either a reduction in slot width, or an increase in capacity, or a reduction of fiber losses, or any combination of these parameters.

 

Benefits

  • One-stage or two-stage screening plant even for high capacities
  • Extremely low reject rates without plugging
  • Increased fibre throughput with high accept consistency and reduced pick passing speed
  • Rejects are almost fibre free in the last stage, although operating continuously
  • Considerable energy savings
  • Considerable installation and space savings
  • Reduced maintenance costs compared to a conventional system
  • Better stickies removal for the last stage compared with a discontinuous tailing screen
