ABSTRACT:
A rotor (1) for impact or hammer mills is formed out of several rotor disks (1) made of cast steel and welded together, where the rotor disks exhibit hubs (3) contacting each other at annular sections representing the longest extension of the rotors in an axial direction. The rotor disks are connected to each other by annular weld seams at the hubs. According to a further embodiment of this rotor, the turn-outs (17), furnished for the weld seams (9) at the front faces of the hubs (3), extend from the outer edges over a substantial part of the radial thickness of the hubs, and the weld seam grooves (16), formed by the turn-outs of the neighboring rotor disks, are filled with welding materials.
