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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
