ROTOR UNIT FOR PROCESSING RECYCLED MATERIAL

A rotor unit in a vessel containing a mixture of water and particles of recycled material, comprising a rotor unit body (19); a screen plate (18) installed to the vessel; a rotor (78) connected to the rotor unit body (19) and configured to rotate inside the vessel, comprising at least two wings (81) configured to slush recycled material in a rotating action and at least two foils (82) configured to clean the screen plate (18) by rotating above the screen plate (18); a space (89) around the rotor (78) defined by a rotor body (77); pipework (21) configured to bring diluting water from outside the vessel to the space (89) around the rotor (78); wherein the rotor body (77) defining the space (89) around the rotor (78) comprises an opening (76) allowing the diluting water to pass through the opening (76) towards the mixture of water and particles of recycled material. The opening (76) at the rotor body (77) is at the same level with the lower edge of the at least two wings (81) or the at least two foils (82), wherein the diluting water is allowed to pass through the opening (76) to the screen plate (18).
