摘要 |
Method and drum filter for thickening of slurry and for treatment of the slurry with liquid. The slurry to be thickened is passed onto the filter face of a drum (3) revolving in a basin (3), and the treatment liquid is passed through the pulp web formed on the drum. The consistency of the pulp web is increased by pressing a compression plate (10) against the pulp web. The compression force of the compression plate (10) is produced by means of the pressure of a liquid and/or gas passed to the convex side of the plate. The compression force can be adjusted by adjusting the pressure prevailing in the gas space outside the drum (3). |
