Rotor, for a pulper, has hardened guides fitted to the leading edges of the rotor blades, which resist wear and are rapidly replaced on site

The rotor (1), especially for a pulper in the papermaking industry, has at least one hardened guide (7) fitted to the rotor by a release mounting or a fixed fastening. The guide is fitted to the leading edge (2A) of a rotor blade (2), with a shearing structure (3) at the leading side (3A) of at least one guide.
