Fibersorter FS.B

Fibersorter FS.B

Operationally reliable screening with the highest contaminant content

The Fibersorter FS.B allows efficient screening and deflaking of paper grades that are difficult to pulp. It achieves a very high degree of deflaking efficiency, i.e. up to 80%.

The Fibersorter FS.B is suitable for intake stock consistencies of 3% to 5%. It works in an absolutely operationally reliable fashion, even with the highest contaminant content, thanks to the use of defibering blocks when deflaking. This achieves an optimized ratio between machine volume and screening surface and a tangential intake.

A continuous light rejects overflow and screen holes with a diameter between 2.0 and 4.0 millimeters also contribute to a high degree of deflaking effectiveness of up to 80%. Rotor assembly is extremely easy thanks to the shrink-on disk. In addition, the fiber screen FS.B has a shaft seal without sealing water.

The Fibersorter FS.B is used in screening for paper grades that are difficult to pulp.
