Improved low consistency screening with Ro-Tec LC rotors

Ro-Tec rotors are designed for approach flow, recycled/deinked, TMP, and groundwood applications. They create lower shear forces, have low pulsation, minimize fiber losses, and contribute towards achieving best power efficiency.

Ro-Tec rotors are application-matched. ANDRITZ Fiedler has the depth of experience to evaluate your process and apply the right combination of rotor and screen basket – ensuring best performance.

Benefits

  • Available to retrofit/upgrade screens from all major OEMs
  • Stickies and other impurities are removed prior to downstream processing
  • Optimized fine screening leads to fewer breaks on PM, coating streaks, or basis weight variations
  • Increased production capacity with minimum long fiber rejection
  • Foils are adjustable so that the gap between rotor and screen basket can be optimized
  • Low pulsation and gentle screening through optimized foil geometries
  • Individual foils and foil sets are easy to replace

Ro-Tec LC

Ro-Tec LC

  • Optimal interaction between pressure and suction impulses
  • High capacity and high screening efficiency in the same unit
  • For consistencies between 0.5 and 3%
 

Ro-Tec LCs

Ro-Tec LCs

  • Counteracts reject thickening
  • Eliminates specific pressure zones so that impurities are not accelerated through the screen basket
  • For consistencies between 0.5 and 4%
 

Ro-Tec EN

Ro-Tec EN

  • Specially designed for headbox screening
  • Extremely low pulsation to ensure uniform flow to the paper machine
  • No stringing and spinning
 

Ro-Tec C

Ro-Tec C

  • Centripetal operation ensures smooth and gentle screening (inflow screens)
  • Centrifugal forces ensure that debris is not caught between basket and rotor
 

Ro-Tec DS

Ro-Tec DS

  • For double screen units where balancing flows is critical to maximum efficiency
  • Well suited for conversions to slotted screen baskets in double screen units
