In a method for concentrating a suspension, where the suspension during increase of its dry content is moving as a web (18) between a first, relatively tight surface (17), and a second, relatively pervious surface (11), which is moving relative to the first surface and through which suction is applied, the suspension web (18) is subjected to shear forces generated by relative movement between the first (17) and the second surface (11), so that particles (21) of the suspension are subjected to rolling between the surfaces. In a device for practising the method means (20) is provided for subjecting the web (18) moving between the first and the second surface for shear forces, so that particles (21) of the suspension are subjected to rolling between the surfaces.
Dans un procédé de concentration d'une suspension, dans lequel la suspension pendant l'augmentation de sa siccité se déplace sous la forme d'une bande (18) entre une première surface relativement imperméable (17) et une seconde surface relativement perméable (11), laquelle se déplace par rapport à la première surface et à travers laquelle une aspiration est appliquée, la bande de suspension (18) est soumise à des forces de cisaillement générées par le mouvement relatif entre la première surface (17) et la seconde surface (11), de sorte que des particules (21) de la suspension sont soumises à un roulement entre les surfaces. Dans un dispositif de mise en application du procédé, on a prévu un moyen (20) destiné à soumettre la bande (18) se déplaçant entre les première et seconde surfaces à des forces de cisaillement, de sorte que des particules (21) de la suspension sont soumises à un roulement entre lesdites surfaces.
