Deflaking

Deflaking - Deflaking offers a tool to eliminate process disturbances in an early process stage. By eliminating large particles from broke, deflaking contributes to a reduced number of web breaks and less screening rejects. Typically, deflaking is applied in CTMP, flash-dried bale pulping, in various coated paper and board machines as well as in tissue broke lines.
