<p>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.</p> |
