Abstract (en)
[origin: WO2019108055A1] Rotary press for sludge or pulp, comprising a rotor and mesh screen at least partially surrounding the rotor, wherein a distance of the mesh screen to the rotor decreases along a direction of rotation of the rotor, and wherein the rotor comprises a hub to which a plurality of blades is attached at their respective proximate edges, each blade having a distal edge for contacting the mesh screen, wherein during rotation of the rotor the mesh screen remains stationary with respect to the press, wherein each blade comprises a flexible portion extending between the a hub and the distal edge, wherein the flexible portion is adapted for, upon contact of the distal edge with the mesh screen during rotation of the rotor and when seen in projection onto a plane normal to the central axis, bending relative to the proximal edge of the blade over an included bend angle of at least 90 degrees.
