Broke screening at high and medium consistency

Protection screening before refining and broke screening

Maximum cleanliness with minimum costs

Small debris in the approach system can cause quality problems like coating streaks or other visual defects and production problems such as web breaks downtime. Broke screening removes impurities before they can enter the paper machine approach system. The broke is screened with narrow slots of 0.15–0.25 mm.

Benefits of broke screening

  • Screening with narrow slots in high consistency area reduces the system and pumping volumes
  • Narrow slots allow the highest screening efficiency
  • Flexible basket/rotor combinations allow easy and quick adaptations for all the different raw materials and applications
  • Optimized rotor dilution options and intermittent rejecting in the tailing screen allow high yield and lowest good fiber losses

Benefits of protection screens - screening instead of high density cleaners

  • Screen cylinders with 4–5 mm holes are an efficient method to stop the bale wires, stones, and coarse debris destroying expensive refiner plates.
  • High-consistency screening with consistencies up to 5% allows the optimum process conditions for LC refining.
  • Intermittent reject removal leads to high yield and minimum good fiber loss
