Deflaker
TOP
Deflaker reduces the flakes in the stock to individual fibres and is suitable for a wide range of applications including waste paper systems, virgin pulp handling and broke systems.
Deflaker 
Excellent defibering with speck-free pulp and minimal change in stock freeness:
The stock suspension enters the deflaker centrally, flows from rotor holes to stator holes and is thus acclerated and decelerated repeatedly. The resulting machinal forces loosen and release the bonds between the individual fibres.
Gap clearance between rotor and stator can be field adjusted in accordance with the furnish to give defibering without any change in stock freeness.
Reduced load on refining system which need not do any defibering,
Reduced pumping energy requirements,
Reduced screening losses.
