Abstract: In the field of mixing rubber mixtures, the invention is directed to a rotor (100) for use in an internal mixer having a mixing vessel in which the rotor rotates, the rotor having one or more blades (104), each blade having a tip (104a) with a profile having a predefined curvature; and an anti-wear device detachably fixed to the tip (104a) of at least one blade, the anti-wear device including a plate (110) with a profile defined by a lower surface (112) with a curvature complementary to that of the tip 104a and an upper surface (114) with a curvature complementary to that of a wall of the vessel to define, between them, a zone of minimum distance that allows passage of the mixture between the plate (110) and the wall of the vessel. The invention is also directed to an internal mixer having at least one mixing vessel in which the disclosed rotor (100) rotates.

Abstract: In the field of mixing rubber mixtures, o a rotor (100), for use in an internal mixer having a mixing vessel in which the rotor rotates includes one or more blades (104), each blade having a tip (104a) with a profile having a predefined curvature and an anti-wear device detachably fixed to the tip (104a) of at least one blade. The anti-wear device includes a plate (110) with a profile defined by a lower surface (112) with a curvature complementary to that of the tip (104a) and an upper surface (114) with a curvature complementary to that of a wall of the vessel to define, between them, a zone of minimum distance that allows a passage of the mixture between the plate (110) and the wall of the vessel. One or more fastening systems (135) are fitted and tightened with respect to the plate (110) so as to engage the rotor (100).
